1. Reduce the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but it must be noted that the rated torque of the reducer cannot be exceeded;
2. Deceleration reduces the inertia of the load at the same time, and the reduction in inertia is the square of the reduction ratio.
Industrial robots are widely used in automobile manufacturing, electrical equipment production, food machinery processing and other industrial manufacturing. With the increase of labor costs, the trend of robots replacing labor is becoming more and more obvious, and the products produced by robots have good consistency and high assembly accuracy. The advantages are getting more and more attention from manufacturers.
At present, the cost of global robots is mainly composed of: about 35% of the reducer, about 20% of the servo, 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 few international robot companies such as ABB, Fanuc and Kuka, and 75% of the precision decelerations they use are manufactured by Japanese companies.
The precision reducers used in the robotics industry can be divided into three types: precision cycloidal pinwheel RV gear reducers, harmonic reducers and planetary reducers. The three of them account for approximately 40% and 40% of the market. , 20%.
In articulated robots, the precision cycloidal pinwheel RV gear reducer is generally placed on the base, arm, shoulder and other heavy loads, and the harmonic reducer is generally placed on the forearm, wrist or hand.
The precision cycloid pin wheel RV gear reducer is the abbreviation of the Rotary Vector reducer. It is a new hybrid of the traditional cycloid pin wheel and planetary gear transmission. The transmission of the RV reducer is relatively large (30- 260).
In the entire industry, 80% of the market for precision cycloidal pinwheel RV gear reducers is still occupied by Japan, and the main brand is Nabtesco.
The transmission device of the precision cycloidal pinwheel RV gear reducer is composed of the first-stage involute cylindrical gear planetary reduction mechanism and the second-stage cycloidal pinwheel planetary reduction mechanism, which is a closed differential gear train.
The active sun gear 1 is connected to the input shaft. If the involute center wheel 1 rotates clockwise, it will drive the three planetary wheels 2 arranged at 120° to revolve around the center wheel axis while still rotating counterclockwise. The three crankshafts 3 are fixedly connected with the planetary gear 2 and rotate at the same speed. Two cycloidal gears 4 with a phase difference of 180° are hinged on the three crankshafts and mesh with a fixed pin wheel, and the needle is wound on its axis. While the wheel axis revolves, it also rotates in the opposite direction, that is, clockwise. The output mechanism (that is, the planet carrier) 6 is driven by the three pairs of crankshaft support bearings mounted on it, and transmits the rotation vector on the cycloid at a speed ratio of 1:1.
RV-E is a two-stage reduction gear. The first-stage reduction is the external meshing of the input gear and the spur gear. The three spur gears are symmetrical to the output shaft at an interval of 120°.
The second-stage reduction drives the eccentric shaft through the spur gear, and drives the RV gear mounted on the eccentric shaft, causing the eccentric movement of the two RV gears. The two RV gears drive the output shaft with a phase difference of 180° to provide a balanced load.
RV-C is a two-stage reduction gear. The first reduction is the external meshing of the input gear and the first central gear, and then the external meshing of the second central gear and the spur gear. The three spur gears are symmetrical to the output shaft at intervals of 120°.
The second-stage reduction drives the eccentric shaft through the spur gear, and drives the RV gear mounted on the eccentric shaft, causing the eccentric movement of the two RV gears. The two RV gears drive the output shaft with a phase difference of 180° to provide a balanced load.
