Precision Reduction Gear RV-E Reducer

Short Description:

Reduction gear RV is a reduction gear for precise motion control which uses a planocentric reduction gear mechanism. This reduction gear design has advantages in rigidity and resistace against overload with a compact body due to a large number of simultaneously engaged gear teeth. Furthermore, minimal backlash, rotational vibration and low inerita lead to rapid acceleration, smooth motion and accurate positioning.


  • Feature 1: Minimal vibration
  • Feature 2: Wide range of reduction ratios
  • Feature 3: High torque density
  • Feature 4: High shock load resistance
  • Feature 5: High rigidity
  • Feature 6: High accuracy

    Features

    _DSC0286

    Integrated angular ball breaings

    Benefits: increases reliabity

    Reduces overall cost

    Attributed to: Built-in angular ball bearing construction improves the ability to support external loads, increases moment rigidity and maximum allowable moment.

    2 Stage reduction

    Benefits: Reduces vibration, Reduces inertia

    Attributed to Low speed rotation of the RV gear reduces vibration Reduced size of the motor coupling part lowers inertia

    FQA

    Q: What should I provide when I choose a gearbox/speed reducer?
    A: The best way is to provide the motor drawing with parameters. Our engineer will check and recommend the most suitable gearbox model for your reference.
    Or you can also provide the below specification as well:
    1) Type, model, and torque.
    2) Ratio or output speed
    3) Working condition and connection method
    4) Quality and installed machine name
    5) Input mode and input speed
    6) Motor brand model or flange and motor shaft size
