Cycloidal RV Gear Reducer , Reduction Gear Box Big Ratio Powerful Roller Bearings

Strong Impact Resistance RV Gear Reducer RV-C Precision Cycloidal Gear RV-200C -34.86

Accuracy 1μm RV gear reducer

The robot RV precision reducer, commonly known as "robot joint", is the core transmission component of high - end automation equipment represented by industrial robots. In the field of global industrial robot core components, the Japanese reducer brand Nabtesco has long occupied 60% to 80% of the international market share of precision reducers for industrial robots.

Nantong Zhenkang is the first company in China to overcome the technical difficulties of RV reducer and realize mass production. It integrates independent design, processing and assembly.

1) Strong detection capability, high - precision Zeiss three - coordinate, gear detector, bearing detector, profilometer, finish meter, industrial computer. The current detection capability of Zhenkang has reached the national professional testing room testing standards.

2) Everyone knows that the precision of the parts is 2μm, and the precision of the tooling cannot exceed 1/3 of 2μm. In order to ensure the accuracy of the tooling, Zhenkang not only purchased the thousand - level Xia Mier wire - cutting machine, Swiss grinding machine, etc., but also modified the special machine tool and independently developed and manufactured the bearing. At present, the self - made bearing precision is stable at P4 level, and some reach P2. level. High - precision machine tools are developed or modified by themselves, achieving an accuracy requirement of 1μm.

3) Zhenkang's production workshop, each station is using a large amount of dust - free paper. Every time the worker uses dust - free paper, the parts and tooling are wiped clean before the clamping process is performed to ensure each part of the reducer. All are μm - class precision. Under this precision requirement, any dust and iron filings that are invisible to the naked eye will affect the accuracy of the parts and the whole machine.

4) In the testing room, a variety of testing equipment and parts are arranged neatly, and each part or machine corresponds to at least one test report.
Each part undergoes rigorous testing before entering the next process, and each machine undergoes rigorous testing before it leaves the factory.

It is not difficult to achieve a precision of 1μm. It is difficult to achieve 1μm at any position of 360 degrees. Only precision, stiffness, noise, backlash, transmission efficiency, temperature rise... all meet the standard is a qualified reducer. ZKRV is such a qualified RV reducer.

Features of RV gear reducer

  • Less than 1 arc - min Backlash.
  • Strong impact resistance.
  • Very compact with high torsional rigidity.
  • Component in - line version for greater design and space saving flexibility.
  • Large transmission ratio range.
  • High transmission efficiency.
  • Long working life, the gear reducer is operated at rated conditions with a life of >6000 hours.
    It is not advisable to operate for longer than the rated speed or rated torque, otherwise the life will be reduced.
    To ensure the accuracy and longevity of the gear unit, please replace the grease after every 2000 hours of operation.
  • The gear unit is operated at rated speed with a noise of < 75 dB.
    The noise level is related to installation accuracy, lubrication, temperature, load and other factors.
