Abstract

The invention relates to a spline shaft stable in an engagement performance. The spline shaft has a spline shaft body, wherein an external thread is arranged at the head part of the spline shaft body; the middle part of the spline shaft body is set as a frustum-shaped mounting end; a key slot is formed in the mounting end; the mounting end and the back end of the spline shaft body are connected through a grinding undercut; and a gear is arranged at the back end of the spline shaft body. The spline shaft is simple in structure, is convenient for use, works through multiple teeth, is excellent in bearing capacity, is high in guide performance, is low in stress concentration, is convenient for machining and manufacturing, is high in machining precision, is not easy to influence normal work of users, improves the working efficiency, and reduces the production cost.

Description

technical field [0001] The invention relates to a spline shaft with stable meshing performance. Background technique [0002] The spline shaft is a kind of mechanical transmission, and the flat key, half-round key, and oblique key have the same function, and they all transmit mechanical torque. There are longitudinal key grooves on the outer surface of the shaft, and the rotating parts on the shaft also have corresponding key grooves. It rotates synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears. The spline shaft uses the cooperation of the ball and the keyway to achieve circumferential positioning, which is more suitable for precision equipment. The spline shaft currently used is prone to meshing instability, poor bearing capacity, poor guiding performance, and stress concentration during use. It cannot obtain high precision during processing and grinding, and at the same time affects the normal work o...
