汽车紧固扭矩的确定方法

The Methods for Tightening Torque of Automotive

对汽车空调压缩机异响进行分析,以压缩机连接螺栓紧固扭矩选择过程为实例,详细说明了应用扭矩法进行装配时紧固扭矩的确定方法,在确定螺栓扭矩的时候,除了螺栓所受预紧力、螺栓机械性能、螺纹摩擦系数、螺纹直径外,还应考虑连接件结构、材料强度影响。

By analyzing the automobile air conditioning compressor noise, taking the compressor bolt tightening torque selection process as an example, showed the definition of tightening torque by the method of torque to as- semble in detail.In determining the bolt torque.When determining the bolt torque, the effect of connected structure and strength of materialsshould be consideredin addition to the bolt preload, bolt mechanical properties, friction coefficient, and screw thread diameter.
