Everything You Need to Know About Worm Gearboxes

gearbox repair technicianIndustrial gearboxes are used all around the world in a variety of applications. There are actually multiple different types of industrial gearboxes that serve different purposes. One common type of industrial gearbox is a worm gearbox. This article is going to explore a few main points that should be known about worm gearboxes.

Like other gearboxes, the worm gearbox is named after the components of the box itself. The worm gearbox contains the worm gear — this gear can transmit power at 90° and as well as in places that require high reductions. The individual parts of the worm gear, the worm screw and worm wheel, work together to allow the gearbox to function properly. This design allows for complete control over the direction and speed of the rotation as well as allowing for a higher torque transmission. The worm shaft can be single- or multiple-threaded depending on the use of the gearbox.

There are many benefits that worm gearboxes can offer. For starters, because they have a low output speed, they run fairly quietly. Additionally, they are relatively small and take up minimal space. And at high transmission ratios, these gearboxes are self-locking.

Because worm gearboxes offer so many benefits, they can be found in a variety of applications. This type of gearbox is commonly used in conveyors, small machinery, and even packaging equipment. This compact size comes in handy when designs have limited space for gearboxes. Additionally, the worm gearbox’s non-reversing application makes it ideal in situations that need to prevent equipment from moving backward, like in the operation of gates and conveyor belts. If a system needs to operate in a way that allows equipment to move in two directions, two worm gearboxes can be used: each direction is controlled by one gearbox.

Because worm gearboxes are commonly used with higher grade materials, like steel, it’s important to find a gearbox repair technician who can specialize in worm gearbox repair services.

Gearbox repair and renewal needs to be done accurately and efficiently in order to ensure the gearbox remains in perfect working condition. So if you have a worm gearbox in need or repair or renewal, make sure you find a gearbox repair technician with the necessary knowledge and skills to get the job done right.

What Is Vibration Analysis and Why Is it Important?

vibration analysisWhen it comes to evaluating the condition of industrial gearboxes, predictive maintenance is key. One method that allows people to avoid problems with their gearboxes is vibration analysis. Vibration maintenance can help users avoid failures and unplanned downtime, reducing costs. But what exactly is vibration analysis? This article is going to provide a brief overview of this gearbox maintenance method.

This process looks for abnormalities and changes in a system. To do this, various vibrations with specified amplitudes, frequencies, and intensities are used to put industrial gearboxes to the test. In doing this, the test can reveal and detect any developing problems and ensure repairs are done correctly.

Before this analysis is done, a baseline must be established. A baseline vibration spectrum is important to be able to identify any abnormalities. It also allows users to tell the differences between normal vibrations that have no effect on the performance of the machinery and dangerous vibrations causing stress to key components.

After a baseline has been established, vibration analyzers will be used to display the vibration spectrum. Today’s processes allow for three axes, vertical, horizontal, and axial, to be shown at the same time, allowing users to see exactly what’s going on in their machinery. It’s important to gather data from all three axes to gather comprehensive data. With data from just one axis, users may not get an accurate reading of the entire machine. If this occurs, a problem could still remain undetected and lead to failure down the line.

Basic principles of predictive maintenance vibration analysis can be applied to a variety of gearbox repair services. During the analysis process, users should watch for high-frequency peaks and match them to the expected frequencies. In doing this, users will be able to determine if a problem is present. This analysis process is crucial in catching problems before they become serious. If problems are detected as soon as they begin, users can reduce downtime needed for repairs as well as significant failures that could lead to even more downtime and expenses.

With machinery manufacturing shipments totaling 7.1%, or $407.4 billion, of all manufacturing shipments as of 2012 , gearbox repair specialists are well experienced in this analysis process. If you’re experiencing any sort of problems with your gearbox, or are looking to avoid problems in the first place, vibration analysis is key. With this process, you’ll be able to detect problems, evaluate performance, and overall ensure your gearbox is in the best shape possible.

Does a Low Speed Engine Need a Gearbox? (Probably Not)

gearbox repair servicesIt probably isn’t news to anyone that a boat and a car aren’t built the same way. There are many aspects of both that differ greatly from each other, while there are some that are very similar. In a boat, the need for a gearbox comes only when the speed capability of the engine exceeds the speed of the propeller and there needs to be a reduction in revolutions. So which speeds need a gear box?

Low Speed Engines
These engines typically do not need a gearbox because the engine and propeller rotate at a matched speed. In most cases, a propeller shaft connects the propeller to the flywheel with a damper shaft to reduce vibration. There are bearings as well to help keep consistent alignment as well.

Medium to High Speed Engines
Engines with speeds that exceed the rotation speed of the propeller will need to have a gearbox to ensure speeds are matched. The gearbox reduced the rotation speed of the final drive to a speed that the propeller can keep up with. In single engine layouts, the gearbox is usually installed between the engine and the propeller. For multiple engine layouts, things can get a little bit more complicated because the gearbox will need to register inputs from both sources. Adding a gearbox however will increase vibration so dampers are commonly used to help reduce this effect. Gearbox repair services can provide vibration analysis to find a more effective solution if necessary.

Gearboxes are usually supplied by the engine maker but many independent gearbox makers will provide products that may be better suited by customers who request them. There are times, however, in which a gearbox will be in need of repair or renewal and gearbox repair services should be used. Many gearbox makers will provide gearbox repair and renewal services and onsite machining. Gearbox repair services should also be asked if shaft ad bearing replacements are also possible. Four of the most common signs that a gearbox is in need of attention are too much noise, excessive vibration (especially if dampers are being used), leaks from anywhere, and oil contamination. These signs can be indicative of bad seals, electrical fluting, or bearing failure and should be looked at quickly to avoid further damage.

Whether in a car or in a boat — you’ll probably find a gearbox. There might be slight differences but both types should have routine inspections and repairs. Nothing is worse than a fast car or a nice boat that you can’t drive.

What Happens During a Gearbox Inspection?

onsite machining servicesThe gearbox is one of the most important parts of your vehicle. Without it, you can’t drive your car. So when something starts to go wrong, it’s important to get your gearbox inspected quickly and efficiently. This article is going to provide a brief overview of what happens during a gearbox inspection.

First, let’s discuss a few signs that your car is telling you that you should get your gearbox inspected.

  1. Dragging clutch: If there’s a grinding noise when you’re trying to shift gear, it’s probably because the still-engaged clutch is failing to disengage and is still spinning with the engine. Luckily, this is generally an inexpensive issue to get fixed.
  2. Slipping gears: Your car should be staying in the gear that you put it in until a change is made. If your car is randomly popping out of gear, get your gearbox looked at right away.
  3. Leaking fluids: Fluid is crucial to a properly functioning gearbox, so even if there is a slight leak it’s important to get it taken care of quickly.
  4. “Check engine” light is on: This is one of the easiest ways to tell when you need to take your vehicle in for inspection – your vehicle is telling you to do so! Your “check engine” light may come on for a variety of reasons, so the mechanic will need to utilize onsite machining services and run a diagnostics test to see what code is showing.

So if you are experiencing one of the problems previously discussed or any other problems with your gearbox, it’s time to take your vehicle in for inspection. When you take your vehicle in for gearbox inspection, it’s a fairly simple process. This process is made easy by onsite machining services. Without the technology mechanics have today, it would take much longer to figure out why something isn’t working properly. With machinery manufacturing shipments totaling $407.4 billion in 2012, the amount of mechanical machines in auto shops has only increased since.

Gearbox repair or inspection will begin with paperwork like most vehicle services do. It’s important to fill out any necessary paperwork to ensure you’re paying for the onsite machining services you need and nothing else. Additionally, it’s important to know the mechanic’s gearbox repair cost and policy on tune-ups and re-inspections if needed.

When it’s time to start the inspection, the gearbox first needs to be cleaned. Like most car parts, your gearbox gets dirty with use so it’s important that it is properly cleaned. Additionally, you should ensure that the area the gearbox inspection is going to take place is clean as well. If the gearbox or surrounding area is dirty, there is a chance something important could be missed during the inspection.

And finally, the gearbox is thoroughly inspected by an experienced mechanic. The mechanic will look for signs of corrosion, overheating, oil leaks, and other damages. The foundation fasteners and the cover fasteners of the gearbox will be checked for signs of tightness. Additionally, the input and output shafts will be checked for leaks. Overall, the entire part will be checked for signs of cracking or damage. Any damage that is found will be fixed accordingly.

When looking for someone to conduct your gearbox repair services, it’s important to choose carefully. The gearbox is a vital part of your vehicle and you should ensure you trust only a qualified, experienced technician to do necessary repairs.

A Short Guide to the Long History of the Gear

industrial gearbox repairsOver the last century and beyond, the machining industry has been one of the most important sectors across the globe. In the U.S., machinery manufacturing shipments totaled roughly $407.4 billion in 2012 — and that’s only 7.1% of all the manufacturing shipments that year.

One aspect of this historic industry that often goes unnoticed is the gear.

While the wheel is normally cited as the most important invention in human history, a strong case could be made for the gear. This simple device allows for the building of incredibly complex machines, and this component is at the heart of the world’s most complex machines. From industrial gearbox repairs to keeping machines running efficiently, gears are essential and should be appreciated much more.

Gears have been an integral part of industry success for much longer than just 100 years. In fact, the Antikythera mechanism is estimated to have been created around the late second century BC.

The Antikythera mechanism is ancient Greece’s version of the gear, an analogue computer used to predict astronomical positions and eclipses for astrological and calendar purposes. It was also used to track the ancient Olympic Games throughout each four-year cycle.

The ancient artifact was discovered in 1902 by Valerios Stais, an archaeologist, among wreckage from a wreck off the coast of the Greek island Antikythera. It contained gears and other components, but one gear attached to the device is approximately 5.5 inches and held 223 teeth.

Famous Greek philosopher and scientist Aristotle provided the world with the earliest description of the gear. He wrote that the “direction of rotation is reversed when one gear wheel drives another gear wheel.” That description might seem simplistic now, but 2,400 ago, it was quite revolutionary.

Today, without industrial gearbox repairs and complicated machine intricacies, manufacturing companies wouldn’t be able to succeed. But the gear is still an important part of today’s industrial success and the history of the world.

If you want to learn more about these simple, yet complex historic devices, contact a professional company that is knowledgeable about industrial gearbox repairs and can provide you with a quality gearbox rebuild guide. Visit Northern Engineering today.

Impellers 101: Understanding the Importance of Impeller Design

gearbox repair and renewalWhen you’re thinking about gearbox repair and renewal, it’s important to understand all of the components surrounding the engine. The impeller design in your vehicle is a critical component of ensuring the efficiency and functionality of your vehicle.

What is an impeller?
Impellers are rotating devices that are designed to change the flow or pressure of liquids, gases, and vapors. They consist of various vanes, or blades, which are arranged around a central shaft. When the device rotates, it sucks in fluids or gases and forces them out the opposite side.

While impellers may seem very similar to propellers, they are used to move different types of objects. A propeller typically refers to a device that moves an object to which it is attached, like a propeller on a boat. On the other hand, impellers are designed to move the substance passing through it without moving the attached object.

Types of impeller designs
Since the impeller is a critical component of your vehicle, the design of the impeller is the most significant factor in determining performance of the car. There are three basic types of impellers:

  1. Open impeller: This impeller design has the vanes free on both sides. Because open impellers are structurally weak, they are generally used in small pumps.
  2. Semi-open impeller: This impeller design consists of free vanes on one side and enclosed vanes on the other. this design offers higher efficiency and strength. Because of this, they are often used in medium-diameter pumps.
  3. Closed impeller: In this impeller design, the vanes are located between the two discs and are usually used in large pumps.

Aside from the overall impeller design, there are also design options for the impeller blades. The blades can be backward-curved, radial, or forward curved. The design of the impeller and its blades is very important to understand, as the design can impact the functionality of your vehicle.

When considering industrial gearbox repair and renewal, it’s important to remember that your a gearbox is a huge factor in the overall functioning of a vehicle or machine. With that in mind, it’s important to look out for warning signs of gearbox problems like vibration, excessive noise, oil contamination, and fluid leaks. Typically, these may be a result of bearing failure, electrical fluting, or leaky seals, but you should always ask experiences gearbox repair specialists to determine the cause of any issues you may be experiencing.
