Technical Field
The utility model belongs to the field of couplings, and particularly relates to a conical self-adjusting coupling.
Background
A coupling is a mechanical device for connecting two or more rotating shafts. The transmission mechanism has the functions of transmitting torque and rotating motion, so that the shafts connected with each other can rotate simultaneously, and the coordination of power transmission and a mechanical system is realized. The coupling is typically composed of two parts: one attached to one shaft and the other attached to the other shaft and tightly coupled by some mechanical means of attachment (e.g., splines, threads, gears, etc.). The coupling is widely applied to various mechanical equipment and transmission systems, such as automobiles, machinery manufacturing, wind generating sets and the like.
However, the coupling in the prior art has some drawbacks, and certain errors, such as axial offset, larger concentricity deviation and the like, always exist between the shafts to be connected, and the errors can cause the problems of vibration, unbalance, abnormal noise and the like when the coupling operates. For example, a spline-type coupling cannot perform small axial and longitudinal displacement to perform self-adjustment when the shafts on both sides are offset, and the service life of components is greatly reduced.
Therefore, a new design is needed that can self-adjust the displacement by a small margin during operation, adjust the posture of the coupler during operation, prolong the service life, and reduce the abnormal noise generated.

When the two-stage transmission part is in a state of being compressed towards the middle, the conical surface of the root part of the fixing pin is contacted with the fixing groove, and the transmission is performed by the friction force provided by the two surfaces. When the transmission part is in a state of stretching leftwards and rightwards, the reverse conical surface at the top of the fixing pin is contacted with the fixing pin, and the transmission is also performed by the friction force provided by the two surfaces.
