0.5M-8M Cylindrical Helical Gears Transmission Parts High Precision Gear

The teeth of cylindrical helical gears are inclined at a certain angle to the axis, forming an involute spiral surface. They have the characteristics of smooth transmission, high load-bearing capacity and low noise, and are widely used in various mechanical transmission systems.

Definition of cylindrical helical gear:

Cylindrical helical gears are cylindrical gears with helical teeth that are inclined to the axis.

Classification of cylindrical gears:
Spur gears, helical gears and herringbone gears

Characteristics of cylindrical helical gear transmission

1. Smooth transmission: Due to the large number of gear pairs meshing at the same time and the long contact line, the impact, noise and vibration of helical gear transmission are small, and the transmission stability is better than that of spur gear.
2. Strong load-bearing capacity: The transmission stability and stress dispersion characteristics of helical gears make them have stronger load-bearing capacity and are suitable for high-speed and high-power transmission.
3. Axial force: Axial force will be generated when helical gears are transmitted.

Structural features of cylindrical helical gears

1. Tooth surface contact line: The contact line on the tooth surface of the helical cylindrical gear is an oblique straight line, which is different from the point contact of the spur gear. This contact mode helps to disperse stress and improve the load-bearing capacity.
2. Number of teeth meshing at the same time: Due to the inclination of the gear teeth, the number of gear pairs meshing at the same time of the helical cylindrical gear during transmission is more than that of the spur gear, which helps to ensure smooth transmission and reduce impact and vibration.
3. Axial force: The helical cylindrical gear will generate axial force during transmission, which is its unique phenomenon and needs to be considered and balanced in the design.
