Mechanical transmission gear spline shaft is a key, key, peace, oblique key as the action is the transfer of mechanical torque, with longitudinal keyway in the shaft sleeve appearance, rotating parts on the shaft also have corresponding keyway, can be maintained with axis synchronous rotating. In the rotation at the same time, some can also be on the axis of the longitudinal sliding, such as transmission gear box, etc..
Spline shaft of gear spline shaft for milling machine in middle section of Longmen
1: is a mechanical transmission, the key to peace, the semicircular key, oblique key role, is the transfer of mechanical torque,
2, structure: a longitudinal keyway in the shaft sleeve appearance, rotating parts on the shaft also have corresponding keyway, can be maintained with axis synchronous rotating. In the rotation at the same time, some can also be on the axis of the longitudinal sliding, such as transmission gear box, etc..
3, application examples: in the brake, steering mechanism. There is also an extension of the shaft, from the inner and outer tubes, the outer tube with inner teeth, the inner tube with the outer teeth, set together. When in use, the rotating torque is transmitted, and the length direction can be extended.
4, material: 40Cr
5, heat treatment. Quenching surface hardness HRC45--50.
