- Suitable for applications with high load-bearing capacity requirements but relatively low precision requirements, such as heavy machinery.
Spur Rack vs Helical Rack
Transmission efficiency
Spur racks have higher transmission efficiency and are suitable for simple linear motion transmission.
Helical racks have a larger tooth surface contact area and slightly lower transmission efficiency, but can provide smoother transmission when the load is large.
Noise and vibration
Spur racks may generate greater noise and vibration during operation, especially at high speeds.
Helical racks usually reduce noise and vibration due to the gradual contact of the tooth surface, and are suitable for noise-sensitive applications.
Load-bearing capacity
Spur racks have lower load-bearing capacity and are suitable for light load applications.
Helical racks have higher load-bearing capacity due to the design of the helical teeth and are suitable for heavy load and high-strength applications.
