Some connection ways are only used for hub connection， and some connection ways can be used as other connecti***. Key and spline are the most common hub connecti***.
楔键联接：键的上下两表面是工作面，键的上表面和轮毂键槽底面均有1∶100的斜度，装配后，圣霖国际联接机，键即楔紧在轴和轮毂的键槽里，工作表面产生很大预紧力。
Wedge key connection: the upper and lower two surfaces of the key are the working faces. The upper surface of the key and the bottom of the hub keyway h***e 1 to 100 slope. After assembly， the key is wedged tightly in the keyway of the shaft and hub， and the working surface has a large pre tightening force.
