Description
Spiral miter gears have their teeth formed along spiral lines. They are somewhat analogous to cylindrical helical gears in that the teeth are angled; however, the teeth are also curved with spiral gears. Spiral Miter gears have a strength, oscillation, and noise level advantage over straight Miter gears. The disadvantage of Spiral miter gears is that they produce an axial thrust load. Therefore proper bearing location and firm support are required for their assembly.
Basic Information
Module: 2 – 5
Material: SCM415
Hardening: Carburized
Tooth finish: Cut (non Ground)
Grade: JIS 4
Gears that have been hardened have excellent strength and wear resistance. Secondary operations are possible except for the teeth.
Product Features
- Right-hand spiral miter 90 degree mesh transmits mechanical power between perpendicular shafts
- The spiral angle of 35 degrees better suits this spiral miter gear for higher speed and larger torque applications than straight miter gears
- Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion
- Hardened teeth for 1:1 gear ratio applications where hardness and strength are needed to transmit torque and motion
- Bore has keyway and setscrew for use with keyed shaft
- Stocked Materials range from steel, brass, and stainless steel
