    摘要: Planacentric gear box having at least one gear wheel with external teeth (8) meshing with a gear ring with internal teeth (5) whose number of teeth is slightly bigger than the number of teeth of the gear wheel (8), this gear wheel (8) orbiting inside the gear ring (5) by the means of two eccentrics (27)(28) synchronously and simultaneously driven by prime reducers having a common input shaft, planacentric gear box for which the eccentic bearings (23)(24) are located outside the gear ring (5), the gear wheel with external teeth (8) being fixed on a torque arm (14) passing beside the gear ring (5), this torque arm (14) having, diametricaly opposed, two protuberances (19)(20) receiving each the outer ring of the bearings for the eccentrics (27)(28) which are generating the orbitation of the gear wheel (8), the median planes of the gear wheel (8) and of the eccentric bearings (23)(24) being close one to the other.
