SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a ball cage universal joint based on damping performance, the steel ball receives external vibration's influence when it can reduce the ball cage universal joint operation, reduces the friction between steel ball and spherical shell, guarantees the stability of steel ball, avoids the steel ball to drop from spherical shell.
The utility model discloses a ball cage universal joint based on damping performance, including spherical shell, primary shaft, secondary shaft, star cover, holder and a plurality of steel ball, be equipped with two at least arcs on the inner wall of spherical shell, every can dismantle in the arc and be equipped with the rubber pad.
Preferably, the number of the rubber pads is equal to that of the steel balls, and the rubber pads are matched with the steel balls in a one-to-one correspondence mode.
Preferably, at least two grooves are formed in the end face, facing the steel ball, of one side of the rubber pad, and lubricating oil is filled in each groove.
Preferably, one end face, facing the steel ball, of each rubber pad is arranged in a step shape along the length direction of the spherical shell.
Preferably, a plurality of through holes are formed in the end arm of the spherical shell, the number of the through holes is equal to that of the steel balls, and the rubber pads are communicated with the external environment of the spherical shell through the through holes.
Compared with the prior art, the utility model has the advantages of:
1. through the arrangement of the rubber pad, the direct contact between the steel ball and the inner wall of the spherical shell is avoided, the abrasion of the steel ball is reduced, and the service life of the universal joint is prolonged.
2. Through the arrangement of the grooves in the rubber pad, lubricating oil is filled in the contact surface between the rubber pad and the steel ball, so that the lubricating property between the steel ball and the rubber pad is ensured, the friction of the steel ball is reduced, and the normal operation of the universal joint is ensured.
3. Through the arrangement of the stepped rubber pads, the full butt between the steel ball and the rubber pads is ensured, the stability of the steel ball in the spherical shell is ensured, and the steel ball is prevented from falling off from the spherical shell.
4. Through the establishment of through-hole, guaranteed spherical shell 1's temperature control, avoided the rubber pad because of the friction temperature rise, the performance reduces.
