Mechanical gearing forged alloy steel spline shaft

Mechanical gearing forged alloy steel spline shaft ：

Spline shaft is a kind of mechanical transmission, flat keys, semicircle keys, oblique keys are the same role, are the transmission of mechanical torque, in the shaft appearance of the longitudinal keyway, sleeve on the shaft of the rotating parts also have corresponding keyway, can keep synchronized with the shaft rotation.At the same time of rotation, some can also be on the shaft for longitudinal sliding, such as the gearbox gear shift.

In the brake, steering mechanism.There is also a telescopic shaft, composed of inner and outer tubes, outer tubes have inner teeth, inner tubes have outer teeth, sleeve together.When in use, the rotation torque can be transferred and the length can be extended.
Material: 40Cr.
Heat treatment.Quench surface hardness HRC45–50 [2].
