What are gears and gearboxes? A gear is a rotating machine part featuring cut teeth or cogs, which is supposed to mesh with another toothed part in order to transmit torque. In a layman’s language, gears are one of the most crucial parts of any motors and machine which help to increase the torque output by providing gear reduction and adjusting the direction of rotation. Two or more gears working together in tandem are called transmission or gearbox. Geared devices are more likely to change the speed, torque, direction of a power source.
Types Of Gears And How Are They Different From Each Other?
Spur gears are the most common products used in a series for large gear reduction. The teeth of spur gears are straight and are mounted in parallel on different shafts.
Unlike Spur gears, Helical gears and Helical Gearbox both have the capacity to conduct a smooth operation. The teeth on a helical gear cut at an angle to the face of the gear. So, during the process when two of the teeth start to engage, the contact is gradual- starting at one end of the tooth and maintaining contact as the gear rotates into full engagement. When it comes to transmissions, helical is the most commonly used gears and it even generates large amounts of thrust.
Bevel gears are mostly used to change the direction of shaft’s rotation. They have teeth in straight, spiral, hypoid shapes. Each one of a kind, for example, straight teeth have similar characteristics to spur gears while spiral operates the same as helical gears as they produce less vibration.
Most of the Industrial Gearbox Suppliers prefer providing Worm Gears to their valuable clients as it is used for large gear reductions. The setup is designed in such a way that setup can turn the gear, but the gear cannot turn the worm. The angle of the worm is shallow and as a result, the gear is used in conveyor systems for brake or emergency stop.
Why Helical Gears?
Helical gears are cylindrical gears whose teeth are not parallel to the axis of rotation. The teeth are angled and appear as a segment of a helix which makes it transmit power between parallel or right angle axes. The main difference between a helical gearbox and others is that the teeth form a helix and has the potential to run more quietly. Another advantage of using these gears are that they will have more capability to transmit load between two parallel shafts as compared to the similar module and equivalent width of spur gears. And of course, there will be less wear and tear as the load will be distributed between several teeth.
Most of the reputable Industrial Gearbox Suppliers suggest helical gears to work under heavy load efficiency and of course when we need silent operation such as automotive applications.
Addition to the above applications, there are many others. The overall application of helical gears and helical gearboxes are widespread. Keep an eye on the space to know more.
