Spiral bevel gears are typically made from hardened steel. The teeth of these gears are usually ground for a far more precise finish spiral gear china allowing for little sound 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 requires a lot of torque then spiral bevel gears are a great option. The gears run at 90° to one another and have “spiral” shaped the teeth which gives maximum tooth surface contact while rotating. With contact spread over the complete tooth the spiral bevel gear can be run much faster compared to the straight tooth bevel gear and handle harder starts and stops.
We make spiral bevel gears only for industrial applications.
Worm gears are used in large gear reductions. Gear ratio ranges of 5:1 to 300:1 are normal. The setup is designed so that the worm can turn the gear, however the gear cannot change the worm. The angle of the worm is shallow and consequently the apparatus is held in place because of the friction between your two. The equipment is situated in applications such as conveyor systems where the locking feature can act as a brake or an emergency stop.
The model cross-section shows a typical placement and utilization of a worm gear. Worm gears have got an inherent safety mechanism built-in to its style given that they cannot function in the invert direction.
