Spiral bevel gears are typically created from hardened steel. The teeth of these gears are usually ground for a far more precise finish enabling 
little noise at high speeds. You can specify left hands or right hand depending on the direction you need to run the gears
If you have a higher 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 teeth which gives maximum tooth surface contact while rotating. With contact spread over the complete tooth the spiral bevel equipment could be run much quicker compared to the straight tooth bevel gear and handle harder begins and stops.
We make spiral bevel gears limited to industrial applications.
Worm gears are used in large gear reductions. Gear ratio ranges of 5:1 to 300:1 are normal. The setup was created to ensure that the worm can change the gear, however the gear cannot convert the worm. The angle of the worm can be shallow and as a result the apparatus is held in place because of the friction between the two. The equipment is situated in applications such as for example conveyor systems where the locking feature can become a brake or an emergency stop.
The model cross-section shows an average placement and use of a worm gear. Worm gears possess an inherent security mechanism built-in to its style since they cannot function in the invert direction.
