Popis: | In this paper, a new static mechanical model is established to study the rolling-sliding contact in the real-time non-clearance precision ball drive. Meshing forces at the main and the secondary transmission force points in two types of mechanical models are deduced shown in moment equilibrium equations and energy balance equations. Based on coupling coefficient determined by the Carter narrow theory, a new mechanical model of coupling rolling and sliding friction is established. The meshing force simulated by the finite element method has good matching with theoretical calculation with error less than 5.6%, which verifies the feasibility of the coupled model. Outcome of the research could be a theoretical support in improving the transmission accuracy of the drive. |
