What should be done about the error of the coupling when using it?

With the development of science and technology, people's requirements for data are becoming higher and higher, and the error of the accuracy of the parts of the equipment is also more and more attention, and the requirements for the coupling industry as a transmission part are the same, although the coupling is also error, but the error is acceptable within the allowable range.



What should be done about the error of the coupling when using it?


In the chemical plant, 50% ~ 70% of the transmission equipment damage is caused by the coupling overbalance, the direct loss is the cost of replacing spare parts, and the indirect loss is the loss of more downtime caused by unplanned shutdown. How to find the alignment error of couplings early and take timely measures to avoid the expansion of losses is a serious concern in chemical plants.
The error of the high-precision coupling, when the output shaft of the coupling is rotated from forward to reverse under the action of the specified torque, the quantity of the output shaft on the Angle is indicated by the code. The optical dial is installed on the input axis of the high-precision coupling, the readout is positioned with the help of the reading microscope, the theodolite is installed on the output axis and the parallel light tube is set in the distance, which is used as the theodolite telescope aiming target.
The transmission error of high-precision coupling, the difference between the actual Angle of the output shaft and the Angle of the output shaft when the input shaft of the coupling is rotating unidirectional, is indicated by the code. The technical requirements, test methods and inspection specifications of high-precision couplings are specified, which provide a basis for the design, manufacture and inspection of high-precision couplings.
In the mechanical transmission of high-precision coupling, the transmission error and space error should be less than that of the device connecting the two axes of the transmission mechanism. No matter how the load changes when the alignment is good, the coupling will operate at close to the ambient temperature, and the temperature of the coupling will increase when the alignment error increases.
