RV Reducer

RV-40E reducer Install the RV-40E on the end of the power arm, the length of the boom is 65cm , that is, 650mm, and the test speed is 20 . Let it press the dial indicator, the reading is 12.047 mm, then the robot arm is lifted and then reset, the dial indicator reading is 12.008 mm after reset, and then after 500 tests, the average absolute value of the error is 0.0549 mm. The perimeter of the top of the boom is 650*2*3.14=4082mm, the perimeter of 1 degree is 11.33mm, then the perimeter of 1 arc minute is 11.33/60=0.18mm, the absolute value of our average error is 0.0549mm, Equivalent to a perimeter of 0.0549/0.18=0.305 arcmin, it has reached a backlash of less than 1 arcmin.
