WH:No buffer and the vibration reduction, radial size is small, small moment of inertia. For less torque, load changes little, no severe impact two shaft connected.

Slider coupling noise , low efficiency , faster wear , generally try not to use only low speed applications, such as ball mill was selected .
The amount of compensation allowable : axial △ x = 1 to 2mm , radially △ y ≦ 0.2 mm , angle to △ α ≤ 40 ' .
Also known as metal slider coupling,Its slider cylindrical ring of steel or wear-resistant alloy , suitable for the speed is low , large transmission torque transmission .By two on the end surface of the opening with grooves semi couplings and a two-sided with a convex tooth intermediate disc . Convex teeth can slide in the recess , it can compensate for the installation and operation of the relative displacement between the two axes .
Material available Steel 45 , the working surface need to be heat treated to increase its hardness ; lower requirement is also available when the Q275 steel without heat treatment . In order to reduce friction and wear , oiling from the intermediate disk hole should be used for lubrication .
Mobile Vice half coupling and intermediate plate , relative rotation can not occur , so the drive shaft and the driven shaft angular velocity should be equal . But in between the two axes , the relative displacement of the case , the intermediate disc will produce a great centrifugal force , thereby increasing the dynamic load and wear .
Generally used for speed n < 250r/min , the stiffness of the shaft , and not at the severe impact .
