[0002] The impeller core shaft taper sleeve is a key component in mechanical transmission. It is mainly used to connect the impeller and the core shaft to realize the transmission of torque and the synchronization of rotational motion. The impeller core shaft taper sleeve is a conical part that is sleeved on the impeller core shaft. Its inner cone surface cooperates with the outer cone surface of the impeller or the core shaft to realize the fastening and transmission functions. The impeller core shaft taper sleeve is usually composed of two parts, namely the inner cone sleeve and the outer cone sleeve (or called the cone sleeve body and the cone sleeve kit). The inner cone sleeve is sleeved on the core shaft, and the outer cone sleeve is connected to the impeller or other components.
