Reducer of component of industrial robot core is the core of mechanical drive, the speed of the robot, precision is concerned with reducer, the reducer that industrial robot uses basically includes: Harmonic reducer, RV reducer. Harmonic reducer generator of wave of join of · motor axis, flexspline encircles the strong base · that manipulator arm joins flexspline is encircled to encircle little N than rigid gear generator of wave of · of tine position of wheel turns circuit, flexspline encircles mobile N · of tine position of wheel can achieve very tall decelerate to compare RV reducer RV-E of RV reducer structure is gear of two class decelerate, decelerate of the first class is input gear is mixed of gear outside clench the teeth, 3 gear (Spur Gear) the interval with 120 ° is symmetrical at take-off. Decelerate of the 2nd class is passed through gear drive eccentric shafe, the RV gear that drives installation to go up in eccentric shafe, cause the prejudicial movement of two RV gear. Two RV gear drives take-off with the phasic difference of 180 ° , in order to offer balance load. RV-C is gear of two class decelerate, decelerate of the first class is input gear and gear wheel of the first center outside clench the teeth, next gear wheel of the 2nd center and of gear outside clench the teeth. 3 gear the interval with 120 ° is symmetrical at take-off. Decelerate of the 2nd class is passed through gear drive eccentric shafe, the RV gear that drives installation to go up in eccentric shafe, cause the prejudicial movement of two RV gear. Two RV gear drives take-off with the phasic difference of 180 ° , in order to offer balance load. The decelerate principle of RV contains inside the core group of crust cylindroid needle roller, the clench the teeth that the prejudicial motion of RV gear causes needle roller and teeth of a cogwheel of cycloidal form RV and break away from, teeth of a cogwheel of RV of generation much group and needle roller at the same time clench the teeth, increase laden capacity. As a result of little １ of needle roller of RV gear ratio amount, rotate when eccentric shafe accordingly when a week, if secure crust (Case) , criterion RV gear and input axis are the same as to turn １ the angle of tine. Outputting end can be transmission shaft (Shaft) or crust (Case) . If crust is secured, criterion transmission shaft is output, output is with direction. If transmission shaft is secured, crust is output, the way of output is apropos and opposite. Change to secure and export a part, can get different drive is compared. CNC Milling CNC Machining
