Selection and Introduction of RV Series Worm Gear Reducer

There are two classification forms for RV series worm gear reducers:

The input forms of RV reducers are divided into: hole input, shaft input, and extended worm shaft type;

The output types of RV reducers are divided into: hole output, one-way shaft output, and two-way shaft output.

The standard basic model is:

NRV25  NRV30  NRV40 NRV50 NRV63  NRV75  NRV90  NRV110  NRV130  NRV150

NMRV25  NMRV30  NMRV40  NMRV50  NMRV63  NMRV75  NMRV90  NMRV110 NMRV130  NMRV150

Suggestions and precautions for selecting RV worm gear reducer models:

The applicable power is usually the applicable power of servo models on the market, and the applicability of reducers is high, with a working coefficient

Both can be maintained at 1.2 or above, and the selection can also be made according to one's own needs:

1. The output shaft diameter of the selected servo motor cannot exceed the larger shaft diameter on the table.

2. If the torque calculation is performed and the speed can meet the normal operation, but there is a shortage when the servo is fully output, we can perform current limiting control on the motor side driver or torque protection on the mechanical shaft, which is necessary. Reduction ratio=servo motor speed/reducer output shaft speed, this universal formula is definitely familiar to everyone! I hope everyone can find a model that is close to the reduction ratio when choosing a gearbox.

Precautions for installation of RV series worm gear reducer:

1. Multiple installation forms can be adopted according to actual requirements, and multiple surfaces can be installed;

2. The installation must be firm and reliable;

3. The working mechanisms of the prime mover and reducer must be carefully aligned, and the error should not exceed the allowable value of the coupling used

Compensation;

4. After installation, it must be flexible and free of jamming when rotated by hand.
