Multifunctional angle calibration device and method for precision speed reducer detector

Abstract

The invention discloses a multifunctional angle calibration device and a method for a precision speed reducer detector. The multifunctional angle calibration device comprises an adapter shell, a rotation system, a combined shaft locking structure and a circular grating angle measurement system. Whether the high-speed end circular grating angle measurement system and the low-speed end circular grating angle measurement system meet the requirement for measurement precision can be judged through the circular grating angle measurement systems in the multifunctional angle calibration device. The actual spline connection gap value in the measurement process can be accurately obtained, and the situation that the gap measurement is inaccurate due to the fact that a spline shaft is not actually used in the calibration process is avoided; furthermore, the error distribution relation of the high-speed end circular grating angle measurement system and the low-speed end circular grating angle measurement system can be obtained at the same time, the relation between input end angular displacement and output end angular displacement is explored more accurately, and the device is applied to parameters related to input end angle measurement and output end angle measurement.

Problems solved by technology

This will lead to the measurement of the gap of the spline connection when the positive and negative conversion is performed when measuring the return difference and torsional stiffness parameters of the reducer, which will introduce measurement errors

Different splines have inconsistent machining accuracy and machining level, and their gaps are also different, so it is not reasonable to use the same spline to replace the gap value of other splines
