Standard polyurethane belt selection method according to the motor output power selection. Another is based on the calculation of the main applications are frequent reversal occasions. The third is effective pulling force, mainly used in low-speed transmission belt occasions.
According to the motor power design, should first determine the motor design features, such as; motor rated power, pulley speed, pulley pitch diameter. According to the motor rated power, combined with the actual conditions, determine the load correction factor, the idler correction factor, speed correction factor, the environmental correction factor, draw the design power, and then according to the diameter of the pitch circle, the speed is converted into a belt Line speed. Combination of the above values, a clear model of the belt, with the calculation of the number of teeth with the pulley, meshing belt and pulley to amend the number of teeth, and then determine the bandwidth, the final design of the transmission to confirm.
According to the actual load design, we must first determine whether the need for positive and negative and rapid speed change, if there is frequent reversal, you need to consider the design of the moment of inertia, to calculate the load moment of inertia, calculate the acceleration and deceleration torque, to determine various Correction coefficient, in determining the type of belt, follow the same steps with the motor power design is the same, if there is no reversal frequent and rapid changes in the occasion, according to the effective design of tension, the effective tension calculation, and then draw the value of its design Rally, in determining the belt model, follow-up steps and then according to the same motor power design.
