Description

Centrifuge coupling

Technical field

The utility model relates to cement electric pole centrifuge field, specifically a kind of centrifuge coupling.

Background technique

Cement electric pole centrifuge transmission shaft divides multistage connection, and rotating speed is fast, and moment of torsion is large, poor working environment, installation and maintenance difficulty is large, because two half-couplings directly connect with bolt when adopting coupling general at present, often there is the situation that bolt fractures, bring impact to the running of centrifuge.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of connecting bolt not frangibility, connects reliable centrifuge coupling.

The technological scheme that the utility model adopts is: provide a kind of centrifuge coupling, comprise the first half-coupling and the second half-coupling, first half-coupling and the second half-coupling are equipped with corresponding axial attachment hole, described first half-coupling is connected by the bolt of through-shaft to attachment hole with the second half-coupling, described axial attachment hole is counterbore, be provided with nylon jacket in the large stomidium of counterbore, described nylon jacket is socketed on bolt.

After adopting above structure; the connecting bolt of the utility model centrifuge coupling is socketed with nylon jacket; coupling is when rotating; when there is coaxiality deviation in the first half-coupling and the second half-coupling; nylon jacket can play the effect of certain buffering and adjustment bias; greatly reduce the connecting bolt shearing force suffered when coupling rotates, play certain protective action to connecting bolt, connection reliability is enhanced.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in detail.

As shown in Figure 1, the utility model centrifuge coupling, comprise the first half-coupling 1 and the second half-coupling 2, first half-coupling 1 is socketed on driving shaft, second half-coupling 2 is socketed on driven shaft, first half-coupling 1 and the second half-coupling 2 are equipped with corresponding axial attachment hole, namely the first half-coupling 1 and the second half-coupling 2 are equipped with the axial attachment hole of even circumferential arrangement, the dead in line of the axial attachment hole of the first half-coupling 1 and the axial attachment hole of second half-coupling 2 corresponding with it, axial attachment hole is counterbore, nylon jacket 3 is provided with in the large stomidium of counterbore, nylon jacket 3 is socketed on bolt 4, namely nylon jacket 3 is located between large stomidium wall and bolt 4.

The utility model in the specific implementation, the large end of the axial attachment hole of the first half-coupling 1 and the second half-coupling 2 is all located at the outside of the first half-coupling 1 and the second half-coupling 2, namely the large end of the axial attachment hole of the first half-coupling 1 is located at the side away from the second half-coupling 2, and the large end of the axial attachment hole of the second half-coupling 2 is located at the side away from the first half-coupling 1.

Nylon jacket 3 in use, is first contained in the large stomidium of axial attachment hole by the utility model, then bolt 4 is run through the axial attachment hole of the first half-coupling 1 and the second half-coupling 2, fastening nut.
