Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1, the present invention includes: axis body 1 the one end of axis body 1 sets up power input driving gear 2, and the other end sets up power output driving gear 3, and power input driving gear 2 and power output driving gear 3 are the arc tooth, and the even distribution on the circumference, its characterized in that: be provided with the mounting hole in power input driving gear 2 and the power output driving gear 3, the buffer is covered with to the mounting hole inner wall, be provided with reference column 4 in the mounting hole.

In this embodiment, the positioning post 4 is preferably arranged coaxially with the mounting hole.

Set up above-mentioned structure, play the pre-positioning effect through reference column 4, improve work efficiency.

In this implementation, it is preferred that buffer includes blotter 5 and strengthens lateral wall 6 and constitute, strengthen lateral wall 6 around pasting on the installing port inner wall, blotter 5 equipartition is on strengthening lateral wall 6.

In this embodiment, the side wall 6 is preferably reinforced with a hard resin.

The arrangement of the structure can protect the shaft body 1 and prolong the service life.

In this embodiment, the cushion pad 5 is preferably distributed in a plurality of particles.
