The width of a timing belt is correct when the permissible values for tooth shear strength, tension cord strength and flexibility are not exceeded under unfavourable operating conditions. In our catalogue, load limits are stated which have been reliably proven and confirmed by bench tests and results obtained in practice. A safety factor is only required for drives with transmission into higher speed.
It is important, that the unfavourable load types occuring in the drive are known resp. correctly estimated by the engineer. With a positive fit transmission, even shortperiod overloads act via the timing belt being the drive member. Some instructions to this issue:
Rated operationDesign timing belts for the operating condition of the rated load. The rated load is the operating condition atwhich the drive should transmit the torque or the power at rated speeds under normal conditions 意拉泰同步带总代理
