The purpose is to find it when the motor works so that the drive shaft.the driven shaft center line in the same line. Looking for the accuracy related to whether the normal operation of the machine, the high speed operation of the machine is especially important. Two absolute accuracy is difficult to achieve in the continuous operation of the machine keep accurate on the even more difficult. All the parts of the uneven thermal expansion, shaft deflection, bearing uneven wear, displacement.base machine generated by uneven subsidence, are caused by the reasons is not easy to maintain on the axis. Therefore, in the design of the machine provides two axis center has a allowable deviation, which is needed to install the coupling. From the perspective of the assembly, as long as to ensure safe.reliable coupling to transmit torque, deviation of axis center allows the greater the value, more easy to reach the installation requirements. But from the installation quality perspective, the center line of the two axes deviation is smaller, the more precise machine running better, longer service life. So, can not put on the two coupling installation allowable deviation as the installer hasty construction of leave allowance.常州市武鸿锅炉辅机设备有限公司
