Gear is a common part often used in mechanical transmission. The gear is made of high-quality high-strength alloy steel, and its surface is carburized and hardened. In practical applications, helical gears are widely used in high-speed and heavy-load occasions because of their stable transmission, low impact, vibration, and noise.

Helical gears are not exactly helical gears, and helical gears are the meshing mode of two helical gears, which are distinguished by the different directions in which they transmit forces in space. Ordinary spur gears are meshed at the same time along the width of the teeth, which results in shock vibration noise and unstable transmission. Helical helical gear transmission is better than straight teeth, and can tighten the center distance for high-speed heavy loads.

The helical gear reducer is a novel reduction transmission. Adopting the optimized and advanced design concept of the module combination system, it has small size, light weight, large transmission torque, smooth starting, and fine transmission ratio classification. It can be arbitrarily connected and selected according to user requirements.

Helical gears are used with parallel shafts similar to spur gears and are cylindrical gears with winding tooth lines, that is the helical gear shaft. They have better teeth meshing than spur gears and have superior quietness and can transmit higher loads, making them suitable for high speed applications. When using helical gears, they create thrust force in the axial direction, necessitating the use of thrust bearings.
