What You Should Know About Worm Gears

There are many gearbox technologies in the market. This being the case, it can be difficult to choose the right gear for a particular speed reduction application. The precision and efficiency of modern worm gears have greatly improved. This being the case, you need to know the various improvements made to find the right worm gear for your application.

There are different factors you should keep in mind when choosing a worm gear. For instance, you should know the right torque, power, speed and ratio of the gear. It is also important to check the acceleration torque, repetitive peak torque and barking torque of the gear. You can know the best worm gear to choose depending on the application you have. Some of the things to keep in mind include the mounting arrangement, efficiency, duty cycle, backlash, smoothness of transmission, shaft alignment, noise, size and weight.

Gear Materials
You should check the material used to make the worm gear you want. You should look for gears made of metal if you have a robotics or automation machine project. However, there are other applications where gears made from plastics are common. A plastic gear will be ideal if your application requires low torque and has low loads. Acetyl, nylon, rugged rubber and delerin are some of the common materials used to make plastic gears. Find out for further details on  Gear cutting right here. 

Types of Worm Gears
You will come across different types of gears in the market. The straight cut gear is the most common one found in the market. Also known as spur, the gear comprising of a disk or cylinder with teeth that project radially and are aligned parallel to the axis of rotation. It is possible to mesh the gears correctly if they are fitted to parallel axes.

One of the benefits of spur gears is that they are more efficient and can handle high ratio gears. However, one of their disadvantages is that the teeth meet suddenly at the line of contact across the whole width. The result is that noise and stress come about. If the gear is rotating at high speeds, the noise can be disturbing. For this reason, spur gears are mostly used in applications that require low speed or where noise control is not a problem.

The other common worm gear is the helical gear. This gear is simply an improvement of the spur gear. The teeth of a helical gear are set at an angle instead of parallel to the rotation axis like is the case with the spur gear. The helix of the helical gear is tooth-shaped. These gears can be meshed in crossed or parallel orientation.
