Industrial robot bearing
Industrial robot reducer with RV reducer, harmonic reducer, cycloidal pin wheel reducer, planetary reducer, etc., the largest consumption, the highest level of technology is the RV reducer and harmonic reducer, master the two kinds of reducer bearing technology, also master the highest technology of industrial robot reducer.
RV reducer bearing
RV reducer, also known as precision joint reducer, is widely used in industrial robots for its small size, strong impact resistance, large torque, high positioning accuracy and many other advantages.
Rv Reducer Bearings include thin-wall
Angular Contact Ball Bearings as the main bearing of the reducer, thin-wall
Tapered Roller Bearings for eccentric shaft positioning and main support, needle roller cage assemblies for cycloidal wheel support, and thin-wall
Deep Groove Ball Bearings for gear support.

Special bearings for harmonic reducer
Harmonic reducer is a kind of wave generator to make flexible wheel produce controllable elastic deformation, the use of flexible bearing controllable elastic deformation to transfer motion and power, it is characterized by compact structure, high motion accuracy, large transmission ratio, used for small and medium torque robot joint.
The flexible bearing is one of the core components of the harmonic reducer, through the flexible bearing elastic deformation to achieve the requirements of high reduction ratio, and the life of the harmonic reducer also largely depends on the life of the flexible bearing. The flexible bearing changes constantly with the elastic deformation of the flexible wheel, which not only bears cyclic stress load, but also bears alternating stress load.

The key technology of | bearing industrial robot
Modern industrial
Robot Bearings to be installed in limited space, must be small size, light weight, that is, lightweight. But at the same time, the robot has the performance of high load, high rotation accuracy, high running smoothness, high positioning speed, high repeated positioning accuracy, long life and high reliability, requiring that the supporting robot bearing must have the performance of high bearing capacity, high precision, high stiffness, low friction torque, long life and high reliability.
Product design:
Thin wall bearings for industrial robots should not only ensure sufficient bearing capacity, but also require accurate positioning and flexible operation. Therefore, bearing design analysis and main parameters determination can not only take the rated dynamic load as the objective function, but also take the rated dynamic load, stiffness and friction torque as the objective function for multi-objective optimization design. At the same time, the finite element analysis method based on ring and frame deformation of thin wall bearing is used.
Manufacturing process and equipment:
(1) High precision detection technology of robot bearing dynamic quality;
(2) Micro-deformation heat treatment of thin-wall bearing rings;
(3) Fine grinding process of bearing rings based on grinding metamorphic layer control;
(4) Precise control technology of thin-wall bearing negative clearance;
(5) Precise control technology of protrusion of thin-wall angular contact ball bearing;
(6) Precision assembly technology of thin-wall bearings;
(7) Non-contact measurement technology of thin wall bearing ring.
Robot | bearing development trend
The development trend of lightweight modern industrial robot also puts forward higher requirements for its supporting bearings. According to the application characteristics of industrial robot bearings, Wuzhou New Spring carries out the optimization design of product structure and process, adopts the design principles of integration, lightweight and multi-rolling body, selects high quality and pure special bearing steel, and pursues the best process path of bearing manufacturing from forging and net forming, precision machining, heat treatment organization, hardness and grain size control, as well as ultra-precision machining. In order to achieve light weight, small body, high precision, long life and other excellent performance, help industrial robots more and more widely serve industrial production and daily life.
