RV-40E

Description

1. Example for calculating RV-40E torqueThe RV-40E is installed at the end of the power arm, the length of the mechanical arm is 67CM, the load is 82KG, and the torque can be calculated as 538.4(N/M), which does not reach the ultimate load.
2. 2. Example of RV-40E precision testThe RV-40E is installed at the end of the power arm, which is 65cm (650mm) long, and the test speed is 20. Then the arm was lifted and reset. After the reset, the gauge read 12.008 mm. After 500 tests, the average absolute error was 0.0549 mm. The motion circumference of the top of the moving arm is 650*2*3.14=4082mm, and the circumference of 1 degree is 11.33mm, so the circumference of 1 arc minute is 11.33/60=0.18mm. The absolute value of our average error is 0.0549mm, which is equivalent to 0.0549/0.18=0.305 arc minute. The back gap has been achieved by less than 1 arc minute.
