PLANETARY REDUCTION DEVICE

摘要

The invention concerns a planetary reduction device comprising an input rotor (202) including a pinion (203), an output rotor (205) including a mobile ring (206) with internal teeth, a fixed ring (211) with internal teeth and satellites (208) meshing with the pinion and comprising first and second gear wheels or first and second portions of gear wheels (209, 210) meshing with the fixed and mobile rings respectively. The diameter of the contact points of the teeth of the mobile ring with the teeth of the first gear wheel portion (209) of the satellite is essentially identical to the diameter of the contact points of the mobile ring with the teeth of the second gear wheel portion (210) of the satellites.
