The characteristics and application range of elastic sleeve pin coupling

The elastic sleeve pin is connected with the flange of the column pin and the two halves. One end of the column pin is fixed with a conical surface and a nut on the conical pin hole on the half flange, and the other end is equipped with an elastic set in the column pin hole of the other half of the flange to realize the elasticity of the transfer torque function. The outer surface of the elastic sleeve is equipped with trapezoidal groove to increase the elastic deformation, and because the outer diameter of the elastic sleeve is slightly smaller than the diameter of the pin hole, the relative displacement of the two axes can be compensated. Due to the small deformation of the elastic sleeve during work, and the fitting gap between the elastic sleeve and the pin hole should not be too large, the cushioning and vibration reduction performance of the elastic sleeve is not high, and the compensation for the relative displacement of the two shafts is small. If the relative displacement of the two axes is too large, the operation performance will deteriorate, the wear of the elastic sleeve is aggravated, and it is easy to damage. In order to adapt to the need of larger angular displacement, the drum elastic sleeve can be used. The main characteristics of elastic sleeve pin are simple structure, easy installation, easy replacement, small size, light weight. If the relative displacement of the two axes can be maintained within the specified range after installation and adjustment, it will have satisfactory performance and long working life. Therefore, it is widely used in the impact load is not large, driven by the motor base rigidity is good, accurate to a variety of medium and small power transmission shafting.
