| 摘要 |
The invention relates to a geared motor (1), consisting of a DC motor (2) with a motor shaft (3), a planetary gear mechanism (4) with a sun gear (5), a plurality of planetary gears (6), an internal gear (7), a gear mechanism housing (8), a gear mechanism output shaft (9) and a planetary carrier (24), wherein the planetary gears (6) are in engagement with toothing systems of the internal gear (7), wherein the planetary gear mechanism (4) consists of one or more planetary gear stages, all sun gears (5, 21), all planetary gears (6, 22) and all planetary carriers (19, 24) are held axially in the gear mechanism housing (8) by way of a disc (10) which is provided with a shaft leadthrough (11), and form a preassembled module, the first sun gear (5) on the motor side has a central shaft receptacle (29) which is configured with a positively locking contour which acts in the rotational direction and is coupled, via a corresponding positively locking contour, to the motor shaft (3) so as to rotate with it or leaving a rotational play, and wherein there is a toothing engagement of the first sun gear (5) with toothing systems of the first planetary gears (6) both before and after final assembly of the DC motor (2) on the preassembed module. |
