Abstract

See full text

A method for checking the design of locking assemblies is provided. A pressure on each contact surface and a torque that can be transferred by a spindle and a bushing after locking assemblies are locked are calculated. The calculated torque is compared with the designed maximum transferable torque to calculate a torque safety coefficient. Based on a minimum fit clearance, a resultant stress of components is calculated and is compared with a yield strength of the material of the components to calculate a strength safety coefficient of the components. A pre-tightening force of the bolts is obtained according to a given pre-tightening moment of the bolts. A maximum equivalent stress of the bolts is calculated to obtain a safety coefficient of the bolts. This method is able to be applied to the manufacturing of the locking assemblies.
