The jacketed coupling uses two axially split jacketed shells, which are clamped by bolts to realize the two-axis connection, and the torque is transmitted by the friction between the surfaces of the two halves of the coupling, and Ping Jian is used as an auxiliary connection.

The double-shell coupling uses two split shells along the axial direction, and the separator of the double-shell coupling has multiple blade branches, among which, like the slider coupling, it is widely used in the case of strong vibration because of its elasticity as a buffer and vibration reduction. The performance limit temperature of the elastomer determines the service temperature of the coupling, which has good universality and wide application range, so it is easy to use and popularize. One of the most prominent advantages of the coupling is that it is only suitable for the difficult installation of axis alignment, thus ensuring its zero clearance performance. Different from the slider coupling, the plum blossom coupling is driven by squeezing, while the slider coupling is driven by shearing force.

performance

The radial and angular axis deviation performance of the jacketed coupling requires that the working environment of auxiliary working hours be minimized. It also matches the plum blossom elastic spacer with the shaft sleeves on both sides by pressing, so as to realize the connection of the two halves of the slider coupling. Good damping performance, simple structure, stable and reliable operation, no noise, no lubrication, simple maintenance, convenient assembly and disassembly, good manufacturability and low cost, and can be derived into various structural forms. The power is transmitted through the extrusion between the claw and the elastic ring, and the relative deviation between the two shafts is compensated by the elastic deformation of the elastic ring, thus realizing damping and buffering.
