Worm Gears for Beginners

There are many gearbox technologies in the market. However, if you have a speed reduction application, it can be a daunting task deciding which gearbox will be right for you. Over the last few years, manufacturers of linear motion devices have come up with new worm gears that are more precise and provide great performance. It is important to know the main features of the improved worm gears to know the right one to use for your application. Read more great facts on Reverse engineering gears , click here.

When you want to buy a worm gear, there are a number of factors you need to consider. For example, it is important to know the ratio, speed, torque and power 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. Maintenance requirements, operating lifespan, smoothness of transmission, noise, weight, size, mounting arrangement, efficiency, backlash, duty cycle, and shaft alignment of your application are a few things you should consider.

Gear Materials
It is important to consider the material that the worm gear is made of. If you want a gear to use in robotics or automation machine projects, you should go for those made of metal. However, you may also want a plastic gear depending on your project. A plastic gear will be ideal if your application requires low torque and has low loads. Plastic gears can be made from a number of materials, including rugged rubber, delerin, nylon and acetyl.

Types of Worm Gears
The gears you will come across in the market will be different depending on a number of things. The most common gear is the straight cut type. 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. The gears can be meshed correctly if they are fitted to parallel axes. For more useful reference regarding Custom gears Cleveland , have a peek here.

One of the benefits of spur gears is that they are more efficient and can handle high ratio gears. However, at the point of contact of the gears, the teeth meet suddenly. As a result, noise and stress are created. This noise can be troublesome when the gear is rotating at high speeds. For this reason, spur gears are mostly used in applications that require low speed or where noise control is not a problem.

The helical gear is the other type of worm gear available in the market. This gear is simply an improvement of the spur gear. With the helical gear, the teeth are set at an angle rather than parallel to the axis of rotation. You will notice that the helix of the gear is shaped like a tooth. These gears can be meshed in crossed or parallel orientation.
