Several principles for the selection of cross slide coupling

　　The important surface for the selection of the cross slide coupling is the rough reference, which requires sufficient margin for each processing surface. The selection principle should be as follows:

　　1. Choose the unprocessed surface as the rough reference;

　　2. Select the surface with a small machining allowance as the rough reference;

　　3. The rough datum can only be used once in the same dimension direction;

　　4. Choose a relatively flat and smooth surface with a larger processing area as the rough reference.

　　In the structural design and series design of the cross slider coupling, the size of the transmission torque, the structure of the coupling and the strength of the hub are used as the basis to determine the range of the shaft hole of the coupling of each specification, and the length of the shaft hole, cross The allowable speed range of the slider coupling is determined by calculation according to the allowable linear speed and the size of the large outer edge of the different materials of the coupling.
