The clamping shell coupling cannot be processed due to the shaft hole being too long. Therefore, a lifting ring is made in the middle of the axial direction to prevent axial movement and to ensure the accuracy of the shaft hole.
The rigid coupling has good starting performance, which can transform the load starting of the motor into no-load transmission, realize the soft starting of the working machine, reduce the starting current, adjust the transmitted torque, realize overload protection, and have compensation performance.
The brake wheel coupling is mainly composed of two protruding teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation.
The JQ type-clamping shell coupling uses two axially split shells, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface, and the flat key is used for Auxiliary connection.
The surface roughness of GY, GYS, GYH couplings refers to the small spacing and small peak and valley unevenness of the machined surface.The distance (wave distance) between the two wave crests or two wave troughs is very small (below 1mm), which is difficult to distinguish with the naked eye, so it belongs to the microscopic geometric shape error.
