Study of the Calculation Method for Direction Angle of Equivalent Coefficient of V-belt Friction

摘要

According to the actual transmit situation of v-belt, analyze radial deformation and circular deformation of any position of dynamicarcarea of driving wheel and driven wheel and the method and Formula Equivalent Coefficient of friction direction angle is given; on the basis of a practical example, a relationship figure of α and Φ has been obtained. In regard to direction angle of friction, find the regular of the equivalent coefficient of friction of driving wheel and driven wheel. in driven wheel the equivalent coefficient of friction decrease with the increase of direction angle; in driving wheel the equivalent coefficient of friction increase with the increase of absolute of direction angle; According to the equivalent coefficient of friction of the driving wheel no more than μ/(sinθ/2), and the formula of limit skid torque, then emplains the numble of actual limit skid torque more the number of theory limit skid torque.
