Spiral bevel gears are typically created from spiral gear china hardened steel. The teeth of these gears are usually ground for a far more precise finish enabling little sound at high speeds. You can specify left hand or right hand based on the direction you should run the gears
If you have a high speed application that will require a lot of torque then spiral bevel gears certainly are a great option. The gears run at 90° to one another and also have “spiral” shaped the teeth which provides maximum tooth surface get in touch with while rotating. With get in touch with spread over the whole tooth the spiral bevel gear could be run much quicker than the straight tooth bevel equipment and handle harder begins and stops.
We make spiral bevel gears limited to industrial applications.
Worm 
gears are found in large equipment reductions. Gear ratio ranges of 5:1 to 300:1 are typical. The setup is designed to ensure that the worm can change the gear, but the equipment cannot convert the worm. The position of the worm is usually shallow and because of this the gear is held in place due to the friction between your two. The gear is found in applications such as for example conveyor systems in which the locking feature can act as a brake or an emergency stop.
The model cross-section shows a typical placement and usage of a worm gear. Worm gears possess an inherent security mechanism built-in to its design given that they cannot function in the reverse direction.
