Spiral bevel gears are typically made from hardened steel. One’s teeth of these gears are usually ground for a more precise finish allowing for little noise 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 high speed application that requires a lot of torque then spiral bevel gears are a great choice. The gears run at 90° to each other and have “spiral” shaped teeth which provides maximum tooth surface contact while rotating. With get in touch with spread over the whole tooth the spiral bevel equipment could be run much faster than the straight tooth bevel equipment and handle harder starts and stops.
We make spiral bevel gears only for industrial applications.
Worm gears are used in large equipment reductions. Gear ratio ranges of 5:1 to 300:1 are typical. The setup was created to ensure that the worm can turn the gear, but the equipment cannot change the worm. The angle of the worm is definitely shallow and consequently the gear is held in place due to 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 a typical placement and utilization of a worm gear. Worm gears have an inherent security mechanism built-in to its design since they cannot function in the invert direction.
