Tooth Design
Spur gear rack: The tooth shape is straight, the tooth line is parallel to the axis, and the design is simple.
Helical gear rack: The tooth shape is spiral, the tooth line is at a certain angle to the axis, and the design is complex.
Transmission Performance
Spur gear rack: High transmission efficiency, but high noise, suitable for low speed and light load.
Helical gear rack: Smooth transmission, low noise, suitable for high speed and high load.
Axial Force
Spur gear rack: No axial force is generated, and the bearing design is simple.
Helical gear rack: Axial force is generated due to the helix angle, and additional bearings are required for balancing.
