Compact RV Speed Reduction Gear,
High Torque RV Cycloidal Gear,
Cycloidal Pinwheel Rv Gear Reducer
There are three main types of reducers for robots: precision cycloid pinwheel RV gear reducer, harmonic reducer, planetary reducer
The cycloidal pinwheel RV gear reducer is mainly used on six-axis robots with heavy loads. The weight of this robot is about 10kg or more. This is still in the no-load state, once loaded, it is heavier. The robot with the largest load currently can load 2 meals. The total volume of the entire fuselage reaches about 10 tons. At this time, there is basically no electric motor that can provide such a large torque. Obviously, it is necessary to rely on a large reducer to increase the torque.
For a super-large robot, you can see that the first axis drive motor is not large, and it is obvious that a reducer is needed to increase the torque.
The precision cycloidal pinwheel RV gear reducer was invented and developed in Japan in the early years. The development of the precision cycloidal pinwheel RV gear reducer in the Chinese market was about 2000. The current RV reducer market is still mainly Japanese brands. Approximately can occupy more than 80%. The main brand Nabtesco, Sumitomo.
(1) RV reducer is mainly composed of three parts:
These three pieces are very important in processing. First of all, we must ensure that the tooth profile accuracy of the cycloid is ±3μm, and the indexing accuracy is within ±5". The accuracy of the eccentric shaft should be within the eccentricity accuracy of ±3μm, and the roundness within ±1μm. As far as machining accuracy is concerned, according to my understanding, the world is basically Japanese: Machining centers such as Yamazaki Mazak, Fanuc, Sumitomo, etc. can handle this accuracy.
(2) Parameter comparison of top brands of RV reducer. China's RV reducer Genius Robotics Zhenkang has indeed reached the top level of the industry, and has the strength of pk with foreign brands.
From these parameters, we can see the gear processing accuracy, transmission efficiency, and stability in long-term use. These three are the key points.
Regarding the characteristic of long-term stability. This kind of durability requires very high materials.
(3) Cost-effectiveness of RV reducer
Any commercial product is inseparable from the cost-effective thing. If it can be manufactured in batches and reduce costs, this is very critical. Genius Robotics Zhenkang precision cycloid RV gear reducer is of high quality and competitive price.
Genius Robotics Zhenkang reducer has been industrialized, and the company has made great breakthroughs in technological innovation, mainly in:
1. Innovation of structural system optimization design;
Solve key scientific issues such as the reasonable layout of the space structure of key components such as eccentric shaft and cycloid pin wheel, interference, gear clearance, and how to adjust the structural size parameters to increase the load-bearing capacity.
2. The double eccentric shaft structure is adopted to improve the heavy load capacity;
The double eccentric structure is adopted to improve the torque and running stability, and improve the heavy load capacity of the reducer. And change the I/O transmission mode: adopt inner circle input and outer circle output to achieve high transmission efficiency.
Third, a heavy-duty RD cycloid gear tooth profile modification technology is proposed.
Study the coupling of forming method and curve gear processing method, according to the change of the gear tooth profile curve and the correlation coefficient in the series, realize the cycloidal needle contour line modification; improve the gear transmission accuracy by modifying the pressure angle and other design methods; The gear shape design and the gear structure are equipped to reduce the gear gap and increase the contact surface area.
Genius Robotics Zhenkang's product advantages are also reflected in a reasonable process route. A set of strict process routes have been formed from the technical route and product plan, with an annual output of 50,000 units a year, providing core equipment for the fast-growing Chinese robotics industry.
