Spiral bevel gears are typically made from hardened steel. The teeth of these gears are often ground for a more precise finish allowing for little sound at high speeds. You can specify left hand or right hand depending on the direction you have 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 operate at 90° to each other and have “spiral” shaped tooth which provides maximum tooth surface contact while rotating. With contact spread over the whole tooth the spiral bevel gear can 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 used in large gear reductions. Gear ratio ranges of 5:1 to 300:1 are common. The setup is designed so that the worm can change the gear, but the equipment cannot switch the worm. The angle of the worm is shallow and consequently 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 become a brake or a crisis stop.
The model cross-section shows a typical placement and utilization of a worm gear. Worm gears have an inherent safety mechanism built-in to its spiral gear china design given that they cannot function in the reverse direction.
