This utility model double reduction implement body operation principle is as follows：Decelerator is divided to two kinds of speed to compare state：
1：When 1, the principle of transmission is that electromagnetic clutch is powered and closes, in running order, brake guaranties release, place
In working condition, so, just make input shaft constitute the dish axle of an integral type with planetary gearsets, make reductor be in 1：1 is defeated
Do well.
1：When 81, the principle of transmission is that electromagnetic clutch power-off discharges, and in off working state, brake power machine is closed
Close braking, in off working state, so since, the revolution of output shaft input passes through after planetary gearsets, to be slowed down,
But, the speed estimated of maximum of single-stage planetary slowing down compares within 15, it is important to how to reach 1 by the planetary gearsets of single-stage：81
Speed ratio, key here is exactly that planetary gearsets have added the external toothing of two few teeth differences, by the one of external tooth of fixation
Circle, then allows the rotating speed that planetary reduction gear is exported to do few teeth difference motion by another movable external toothing again, and again one group of generation is fast
Than, two groups of speed than product be the output speed ratio of decelerator, as soon as so having reached single-stage planetary and slowed down and not accomplished
Band reaches the purpose of the small volume of large speed ratio than scope.
Prior art is different from, this utility model double reduction device can realize speed-changing ratio, and switching mode is simple,
Stability Analysis of Structures, using effect is good
