Low Backlash Cycloidal Pin Gearbox Speed Reducer Motor Internal Angular Support Bearings

The presence of a precision cycloidal pin gear speed reducer allows the servo motor to operate at a suitable speed and accurately reduce the speed to the speed required by various parts of the industrial robot, increasing the rigidity of the machine while outputting greater torque. Compared with universal reducers, industrial robot joint reducers require short drive chains, small size, high power, light weight and easy control.

There are two main types of reducers that are widely used on articulated industrial robots: cycloidal pin gear speed reducer and harmonic reducers. Compared to harmonic reducers, cycloidal pin gear speed reducer have higher stiffness and rotational accuracy. Therefore, in an articulated industrial robot, the cycloidal pin gear speed reducer is generally placed at a heavy load such as a base, a boom, a shoulder, etc., and the harmonic reducer is placed at the arm, wrist or hand.

Nabtesco Japan, World Speed Reducer

Nabtesco was founded in September 2003. In fact, it is composed of a combination of Teijin Seiki and Nabok. As the world's largest company in the field of precision reducers for industrial robot joints, Nabtesco accounts for 60% of the global market.

The Japanese Teijin Seiki was established in 1944. Around 1980, Teijin Seiki proposed the RV transmission theory and started to apply to the robot industry. In 1986, the Teijin Seiki RV reducer was officially mass-produced and succeeded.

As a manufacturer of motion control systems and components, both companies have mastered high - end core technologies in their specific business areas and controlled a high market share. In 2003, Teijin Seiki and Nabok merged to form Nabtesco, which has developed into a leader in the RV gearbox industry, accounting for more than 60% of the market, especially in medium / heavy duty robots, and its RV reducer market. The share is as high as 90%.

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

    Shanghai Genius Industrial Co.,Ltd is the branch of Nantong Zhenkang Machinery Co.,Ltd, which founded in 1993, with 30 years of experience in the production of CO2 welding wire feeder, nowadays we occupy 70% Chinese market and 50% global market for wire feeder, long partners of PANASONIC and OTC Daihen.

    In 2009, we started R&D high precison RV reduction gearbox, this is core part of industrial robots, through 4 years research and development, in 2013, our high precision RV reduction gearbox start bulk production. Nowadays we become China biggest RV reduction gearbox manufacturer, realized robotic automatically produce RV reduction gearbox, also we are supplier of world famous company ABB, FNUC, YASKAWA for gearbox.

    As had advantage of wire feeder and RV gear reducer, with accumulated years of welding experience, we decide to R&D welding robot, After more than one year testing, our welding robot developed successfully in 2016, much earlier than other robot manufacturers in China, now our robot already in market for 5 years, still work well, got good comments from customers.
