XINLAN analyzes transmission error and idle travel error

Transmission error

In high precisionCouplingAn optical dial is installed on the input shaft of the instrument, and it is positioned with the help of a reading microscope (a dial indicator can also be used as a positioning device), a theodolite is installed on the output shaft, and a collimator is set at a distance as the aiming target of the theodolite telescope.After that, turn the output shaft through a certain angle, and record the reading of the optical dial. At this time, the theodolite on the output shaft will also turn the corresponding angle, and then turn the telescope of the theodolite back to re-aim the collimator and crosshairs. At this time, the rotation angle of the theodolite is the actual rotation angle of the output shaft, and the difference between the rotation angle and the theoretical rotation angle is the transmission error of the output shaft in the shop.The sequential method is measured in the range of one revolution of the output shaft, and the average value of 7~10 points is taken to obtain the transmission error of the high-precision coupling.

Empty scale error:

First, fix the coupling on the test frame, fix one end of the shaft on the test price, fix the block gauge at the other end and add weights, align the block gauge with a parallel light pipe, debug the reflection cross line of the block gauge and write down the initial Readings, the difference between the two is the corresponding torsion deformation angle, and multiplying this deformation angle by 2 is the nominal error of the coupling.Add weights one by one to measure the deformation angle under each corresponding torsion.
