摘要:

通过对虎克万向节运动特性的分析,利用空间坐标变换法及空间投影几何法,建立虎克万向节轴承的瞬时转角方程,并建立轴承瞬时转速分析的数值方法,分析轴承的瞬时转速及瞬时转角与轴间夹角之间的关系;采用运动仿真法验证了分析结果的正确性。分析结果表明:主动叉头的轴承瞬时转速与从动轴承的瞬时转速并不相等,主动轴承的瞬时转速的波动大于从动轴承的瞬时转速的波动。研究结果为分析虎克万向节轴承的摩擦、磨损及润滑状态提供依据。

Abstract:

The formulas of bearing rotation angle in Hooke's joint were established based on  the coordinate transformation  method and space perspective geometry according to the analysis of kinetics' behaviors of the Hooke's  joint. A numerical method  for calculating bearing  rotation speed  in  Hooke's  joint was set up. By adaption of above mentioned formulas and numerical method, the relations  among  instantaneous rotation angle, rotational speed and true joint angle were  analyzed, and the  results were validated by kinematics simulation. The results indicate that the bearing rotation speed in driving fork is higher than that in driven fork and the bearing rotation speed wave in  driving fork is higher than that  in  driven fork. The conclusions obtained give basis for analysis of friction, abrasion and lubrication state of bearings in Hooke's joint.

Key words: Hooke joint, space perspective geometry, bearing, motion characteristic analysis
