Description

Technical Field

[0001] The utility model relates to the technical field of reducer testing, in particular to a precision reducer backlash testing device. Background Art

[0002] The precision reducer hysteresis test device is a device used to test the hysteresis of the reducer. Hysteresis refers to the percentage of the output shaft speed difference during the forward and reverse switching process of the reducer. The test device mainly measures the output shaft speed during the forward and reverse switching and calculates the hysteresis value to evaluate the performance of the reducer. Generally speaking, the precision reducer hysteresis test device mainly includes the following parts: drive system: used to drive the reducer to switch forward and reverse. Measurement system: used to measure the forward and reverse speed of the output shaft, such as photoelectric encoder or Hall sensor. Control system: used to control the drive system to switch forward and reverse, and process the measured data to calculate the hysteresis value. Display and storage system: used to display test results and store data. Communication interface: used to communicate data with the host computer or other devices. The test process is as follows: Set test parameters, such as the number of tests, switching speed, etc. Start the drive system to switch the reducer forward and reverse. The measurement system collects the output shaft speed in real time and sends it to the control system. The control system calculates the hysteresis value and sends it to the display and storage system. The display and storage system displays the hysteresis value in real time and stores it in the database. After the test is completed, the test data is uploaded to the host computer or other equipment through the communication interface. The test data is analyzed to evaluate the reducer performance. However, the current precision reducer backlash test device is cumbersome to operate and requires a lot of calculations and operations, resulting in low test efficiency.
