Precision gear shaft spline related presentations
1, precision gear shaft spline functions: mechanical transmission is one of peace key, Woodruff key, oblique key role, are transmitting mechanical torque on the outer shaft has a longitudinal keyway, set in the axis of the rotary member also has a corresponding keyway, can be synchronized with the rotation axis. While rotating, and some can also slide longitudinally on the shaft, such as transmission shifting gears.
2, precision spline shaft gear structure: the outer shaft has a longitudinal keyway, set in the axis of the rotary member also has a corresponding keyway, can be synchronized with the rotation axis. While rotating, and some can also slide longitudinally on the shaft, such as transmission shifting gears.
3, precision gear shaft spline Application Example: brakes, steering mechanism. There is also a telescopic shaft, inner and outer tubes, an outer tube with internal gear teeth, the inner tube with external gear teeth, sets together. While transmitting the rotational torque, in the longitudinal direction can be scaled used.
4, precision gear spline shaft heat treatment: hardening the surface hardness HRC45--50.
