| description | The purpose of this study is to propose an effective model for predicting the slip ratio of a belt transmission mechanism during power transmission, considering the different tensile stiffness of the drive belt. The slip ratio of the belt mechanism was measured under a constant applied torque to compare it with the theoretical value based on belt elastic elongation. The apparent friction coefficient between the belt material and the pulley was measured using a laboratory-made counter-type disc-on-block friction tester under a constant fixed slip velocity condition. The test results showed that when a soft rubber belt was used, the slip ratio of the belt mechanism could be accurately predicted by considering only the elastic elongation of the belt itself. However, when a rigid metal belt was used, the experimental slip ratio of the belt mechanism was larger than the theoretical value. The observed friction coefficient between the belt material and the pulley indicated that the friction force depended on the slip velocity, with the friction force at low slip velocity being smaller than that at high slip velocity. Based on these results, a prediction model for the slip ratio was proposed, considering micro-slip due to the varied frictional coefficient, and its validity was examined. |
