Robot planetary reducer boosts robot industry

Workers who want to do their best must first sharpen their tools. The emergence of robot planetary reducers has provided the possibility for the rapid development of modern robots.

The planetary reducer is an intermediate device that connects the power source and the actuator. Generally, it uses the small gear on the input shaft to mesh with the large gear on the output shaft to achieve the purpose of speed reduction. Torque is widely used in automation equipment. For robots, robot planetary reducer is an essential core component. Different from the planetary reducer for conventional automation equipment, because general robots will constantly perform repetitive actions during work, the positioning accuracy and repeated positioning accuracy requirements are very high, and robots, especially light robots, are compared with large automation equipment. Small size and light weight, so as a core part, the planetary reducer should also meet the requirements of light weight.

The reducers currently used in industrial robots are mainly planetary reducers (rectangular coordinate robots), harmonic reducers and RV reducers (articulated robots). Planets, as the name suggests, are orbiting stars. Planetary reducers have three planetary wheels that rotate around a sun wheel. The planetary reducer is small in size, light in weight, high in bearing capacity, long in service life, stable in operation, and low in noise. It has the characteristics of power splitting and multi-tooth meshing, and is widely used in industry.

However, when one set of planetary gears cannot meet the larger transmission ratio, two or three sets are required to meet the user's requirements for larger transmission ratios. Therefore, if the number of planetary gears is increased, the volume will become larger and cannot meet the requirements Therefore, planetary reducers are mostly used in Cartesian robots.

Precision planetary reducer, flange output, firm installation; it can reduce the speed of the motor and increase the output torque at the same time. It has the characteristics of high rigidity, high output torque, high stability, low noise, long life, wide adaptability to the motor, etc.

Driven by the development of the robot industry, domestic manufacturers realize the importance of the planetary reducer as a component and have also made continuous progress. In terms of planetary reducers, domestic manufacturers have gradually narrowed the gap with foreign products, and are constantly seeking breakthroughs in planetary reducers. The state has also issued related policies in recent years and has given great support. It is believed that in the context of market prosperity and policy support, the rise of robot planetary reducers is just around the corner.
