The coupling torque transmission function becomes an important criterion for coupling selection. So how do we come to the correct calculation of a coupling in the end to pass much of the torque? Here we come to a specific introduction.

    For standard couplings, each model has a permissible torque value, so when choosing a model, the coupling actually needs to deliver torque less than the permissible torque [T] of the selected coupling. Couplings actually need to pass the torque commonly used to calculate the torque T0. , It is equal to the theoretical torque T of the coupling multiplied by the operating condition coefficient K. Therefore, the above conditions can be expressed as: T0 = KT.

    The coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole form, the connection form and the size mainly depend on the type and size of the connected shaft, Product design generally cylindrical and conical shaft depth of the international standard design axis, shaft depth standard is designed for the shaft. The shaft drive is usually connected by one or several couplings to the main and slave shafts to form a shaft drive system to transmit rotation or movement. The power of the power machine in the transmission system should be greater than the power required by the workpiece. According to the power factor and speed of the power machine can be calculated with the power machine connected to the high-speed side of the theoretical short moment T; according to the working coefficient K and other relevant coefficients, can calculate the coupling torque Tc. The coupling T is inversely proportional to n, so the low speed terminal T is greater than the high speed terminal T.
