The inventive internal eccentric planetary gear relates to mechanical engineering, in particular to internal mechanical planetary gears whose central gear axis is arranged inside the basic circle of a planetary pinion and whose gearwheels have an insignificant size difference. The inventive gear comprises two mutually embracing collars (1, 2) which form a module with the aid of bearings (4, 6; 5, 7) and an eccentric socket (3). The axes of rotation (OO1, CC1) of the collars are offset with respect to each other. Any collar is provided with an eccentric section (9) on which a planetary wheel (11) is fitted by means of bearings (10), therein a mounting bore is shifted from the satellite gear centre and the sun gear (13) of the internal gear set is rigidly connected to the other collar. The external collar (2) and eccentric socket (3) are provided with elements (15, 14) for connecting to the shaft and body of an external mechanism, respectively. |
