Gears

5241 Products

Straight-tooth cylindrical gears transmitting motion and power between parallel shafts with high efficiency, simple design, and reliable performance in moderate-speed applications.

Miter Gears and Bevel Gears

Miter gears and bevel gears transmit power between intersecting shafts, typically at a 90° angle. Bevel gears can have different numbers of teeth to change speed and torque, while miter gears have equal tooth counts that provide a 1:1 speed ratio for direction change only. Both are available in straight, spiral, or zerol designs to suit different load and noise requirements.

Worms and Worm Gears

A screw-like worm driving a worm gear to achieve high reduction ratios, smooth and quiet operation, self-locking capability, but lower efficiency due to sliding contact.

Ratcheting Gears

Gears working with pawls to allow rotation in one direction while preventing reverse motion, providing controlled motion in mechanisms requiring unidirectional drive.

Helical Gears

Gears with angled teeth for smoother, quieter operation and higher load capacity than spur gears, ideal for high-speed applications.

Gear Rod Stock

Gear rod stock is a continuous length of gear-shaped material, typically made from metal or plastic, used for custom gear manufacturing or for creating gear racks and other gear components in various mechanical applications.

Gear Tooth Pitch Identifiers

Measuring tools with calibrated profiles to identify gear tooth pitch, module, and spacing, ensuring compatibility, accurate meshing, and proper gear system function.

What Is a Gear?

A gear is a mechanical component designed with evenly spaced teeth along a cylindrical or conical surface, enabling the transfer of torque and rotational motion between shafts. By interlocking with another toothed part, gears ensure precise power transmission, allowing adjustment of speed, direction, and torque. Depending on design, gear teeth may be cut or molded directly into the gear body. When two or more gears operate together, they form a gear train, while a toothed linear element known as a rack enables conversion between rotary and linear motion.

Key Functions of Gears

Speed Regulation

Gears enable precise control of rotational speed. By selecting appropriate gear ratios, our products can either increase output speed or reduce it while maintaining optimal torque.

Power Transmission

Interlocking gear teeth ensure smooth and slip-free power transfer between shafts, providing consistent motion and energy efficiency in industrial systems.

Torque Adjustment

Gears can amplify torque or increase speed depending on the ratio. Overall efficiency depends on gear type and lubrication.

Directional Control

Through careful design and configuration, gears can change the direction of rotation, enabling compact and versatile machinery designs for automotive, industrial, and precision equipment.
