a plurality of spline grooves are formed in the periphery of the spline shaft, and a baffle ring is fixedly installed at the end part of the spline shaft through a countersunk bolt;

one side that the spline shaft sleeve is close to the integral key shaft is constructed with the arch with spline groove adaptation, the inside of spline shaft sleeve is constructed with the spout with spline shaft adaptation, and the internal peripheral thread of spline shaft sleeve is connected with sealed apron, the inner wall welded fastening of sealed apron has many damping spring, many damping spring's tip all with keep off the ring butt.

Furthermore, lubricating grease is coated on the surface of the spline groove; the lubricating grease is beneficial to the sliding between the spline shaft and the spline shaft sleeve.

Further, the periphery of the sealing cover plate is configured with a thread groove; the sealing cover plate is convenient to take down and install, the use is convenient, and the damping spring is convenient to replace.

Furthermore, the outer diameter of the baffle ring is equal to that of the spline shaft; the spline shaft and the spline shaft sleeve can be ensured to normally slide.

Further, a plurality of the spline grooves are distributed in an annular array.

Compared with the prior art, the utility model has the following beneficial effects: one end of the spline shaft is provided with a fixed baffle ring through a countersunk bolt, the other end of the spline shaft penetrates through the spline shaft sleeve, and the transmission shaft and the spline shaft are connected and fixed through a connecting column, so that the installation can be completed, the use is convenient, and the structure is simple; the spline shaft and the spline shaft sleeve can be prevented from being separated through the arranged baffle ring and the arranged bulge; when the spline shaft and the spline shaft sleeve slide relatively, the spline shaft can extrude the damping spring, so that the impact effect between the spline shaft and the spline shaft sleeve is reduced, the noise is reduced, and the service life is prolonged.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, a spline shaft sleeve special for a transmission bearing comprises a transmission shaft 1, and further comprises a spline shaft 2 and a spline shaft sleeve 3, wherein a connection column 4 is fixedly welded at the end of the transmission shaft 1, the spline shaft 2 is fixedly connected at the end of the connection column 4, and the spline shaft sleeve 3 is slidably connected to the periphery of the spline shaft 2;

a plurality of spline grooves 21 are formed in the periphery of the spline shaft 2, and a retaining ring 22 is fixedly installed at the end of the spline shaft 2 through a countersunk bolt;

spline shaft sleeve 3 is close to one side of integral key shaft 2 and is constructed the arch 31 with spline shaft 21 adaptation, spline shaft sleeve 3's inside is constructed the spout with spline shaft 2 adaptation, and spline shaft sleeve 3's internal peripheral thread is connected with sealed apron 5, the inner wall welded fastening of sealed apron 5 has many damping spring 32, many damping spring 32's tip all with keep off ring 22 butt.
