About Gears

Gears Sold Separately

With Keyed Bore and Set Screw

With straight, conically shaped teeth and a 1:1 speed ratio, miter gears connect two shafts at an angle without changing shaft speed or torque. They're more efficient than spiral miter gears because they create less friction.

For two gears to mesh correctly, they must have the same pressure angle, shaft angle, pitch/module, and number of teeth.

Carbon steel gears have hard, strong, and wear-resistant teeth. They’re best for heavy duty and high-torque applications, such as lifting equipment. However, these gears will rust when exposed to moisture or corrosive chemicals. Some gears have hardened teeth for additional wear resistance; gears with teeth that are not hardened can be hardened to fit your application.

Stainless steel gears won’t rust in damp or wet environments. They’re commonly used in food-processing plants and other areas where frequent cleaning takes place.

High-Power Metal Bevel Gears

Gear and Pinion Sold Separately

Made from carbon steel with spiral teeth, these gears handle heavier loads at higher speeds than bevel gears with straight teeth because their teeth stay in contact longer. Their teeth engage gradually, which reduces vibration and noise, and they’re hardened for extra wear resistance. Use these gears to transmit motion at a right angle while changing shaft speed and torque. They reduce speeds at ratios of 2:1, 3:1, or 4:1. Customize their machinable bore to fit them on a variety of shafts. They’re also known as spiral bevel gears.

A complete set consists of a gear and pinion (sold separately). The gear is larger than the pinion, but for them to mesh correctly, they must have the same pressure angle, module, and face width.

Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear. To increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.
