Slider couplingWhen designing the structure, based on the size of the transmitted torque, the structure of the coupling and the strength of the hub, determine the shaft hole range (maximum and minimum shaft hole) of the coupling of each specification and the long cross slider coupling of the shaft hole The allowable speed range of the coupling is determined by calculation according to the allowable linear speed and maximum outer edge size of different materials of the coupling.
The allowable speed range of Oldham couplings of different materials, varieties and specifications are different. Changing the material of the coupling can increase the allowable speed range of the coupling. The allowable speed range for steel is greater than the allowable speed for cast iron. Use speed.If it is used for the coupling under the working condition of n>5000r/min, the influence factors such as the centrifugal force of the outer edge of the coupling and the deformation of the elastic element should be considered, and the dynamic balance should be carried out.Non-metallic elastic element elastic couplings should not be used at high speeds. When the elastic elements are deformed at high speeds, high-precision flexible couplings should be selected. The couplings used for high-speed abroad are nothing more than diaphragm couplings and high-speed couplings. Precision drum gear coupling.
