A rack is a component that has teeth made on a flat plate or a straight rod, and there are two types: straight rack and helical rack. The straight rack meshes with spur gears and facilitates the conversion between linear motion and rotational motion. The helical rack meshes with helical gears and also facilitates the conversion between linear motion and rotational motion. They are used in machine tools and printing machines, among other applications. For more details, please contact us.

• gear

A worm is something that resembles a screw made on a round rod, and a worm wheel is something that meshes with it, similar to a helical gear. The combination of these two is called a worm gear. Worms can have one or multiple threads. They can achieve a large reduction ratio and operate quietly, but they have low efficiency and require attention to issues like heat generation. Worm gears are used in various machines, such as elevators and escalators. For more details, please contact us.

• gear

It is a cylindrical gear with tooth profiles that are helical. It may appear to be a type of spur gear with its teeth angled, but it offers advantages in strength, vibration, and noise compared to spur gears, although it generates thrust (axial force). In everyday applications, such as in automobile transmissions, where quiet operation is required under high speed and heavy load, helical gears are commonly used. It is also known as a helical gear.

• gear

An internal gear is a gear with teeth formed on the inside of a cylinder or cone. It is commonly used in planetary gear mechanisms. A regular gear is an external gear. The counterpart that meshes with an internal gear is always an external gear. Internal gears do not mesh with each other. Furthermore, the internal gear is always the larger gear, while the meshing external gear is always the smaller gear. The smaller gear is referred to as a pinion.

• gear

This is a cylindrical gear with teeth that are parallel to the axis. It is easy to manufacture and assemble, making it the most popular type of gear. Since spur gears do not generate thrust loads (axial loads) associated with power transmission, they can be adequately supported by standard deep groove ball bearings that handle radial loads perpendicular to the axis.
