The cost of the global robot is mainly composed of: about 35% of the reducer, about 20% of the servo machine, about 15% of the control system, and only about 15% of the mechanical processing of the robot body. The world's high-end robots are mainly controlled by a small number of international robotics companies such as ABB, Fanuc and Kuka, and 75% of the fine deceleration they use is made by Japan companies.
The fine reducer used in the robot industry can be divided into three types: RV reducer, harmonic reducer and planetary reducer, and the proportion of the three in the market is about: 40%, 40% and 20%.
Industrial robots are widely used in car production, electrical equipment production, food machinery processing and other industries, with the growth of labor costs in China, the trend of robots replacing labor is becoming more and more significant, and the products produced by robots have good consistency, installation accuracy and advanced advantages are also more and more valued by manufacturers.
The working principle of harmonic reducer
The technical difficulties of the harmonic reducer are mainly reflected in the life of the flexible wheel and the machining accuracy.
Harmonic reducer structure
Harmonic transmission reducer, a kind of gear transmission that relies on the flexible bearing installed on the wave generator to produce controllable elastic deformation of the flexible gear, and meshes with the rigid gear to transmit motion and power.
RV reducer structure
The transmission device of the RV reducer is composed of two parts: the planetary deceleration organization of the involute cylindrical gear and the planetary deceleration organization of the second-stage cycloidal pinwheel, which is a closed differential gear train.
The active sun wheel 1 is connected with the input shaft, if the involute center wheel 1 rotates clockwise, it will drive three planetary wheels 2 that are arranged in 120 ° to rotate together around the axis of the central wheel and rotate in the counterclockwise direction, three crank shafts 3 are connected with planetary wheel 2 and roll at the same speed, the cycloidal wheel 4 of two pieces of phase difference 180 ° is hinged on three crank shafts, and is meshed with the fixed needle wheel, and together with the axis of its axis revolves around the axis of the needle wheel, it will also rotate in the opposite direction, that is, it rolls clockwise. The output organization (i.e., planetary carrier) 6 is propelled by three pairs of crank shaft support bearings mounted on it, and the rotation vector on the cycloidal wheel is transmitted at a speed ratio of 1:1
The operating principle of RV reducer
The difficulty of the RV reducer manufacturing center lies in the close cooperation of various processes, including: tooth surface heat treatment, machining accuracy, part symmetry, group skills, installation accuracy, etc., and the result of the total distribution of the general assembly tolerance of these processes is the wear and life of the product.
