<p>A planetary gear has a central input shaft (12) with a spur gear (7). The spur gear (7) is in mesh with a planetary gear wheel (6), located on a transmission shaft (5). The transmission shaft (5) is carried by a central disc (8) so that it can orbit about the central gear axis. The output shaft of the gear (9) is an integral part of the disc (8). The input torque from shaft (12) is thus transmitted to the drive shaft (5) and from there by two similar gear wheels (3, 4) to the gear housing (1). To balance the rotating disc (8), a weight (13) or an identical gear wheel arrangement is located diametrically opposite the first one.</p> |
