Planet gear and use thereof

A friction transmitting connecting, the friction transmitting connecting with the input/output shaft of a centre, can rotate (1a), an elastic outer ring (4); and elastic outer ring of the elastic deformation, surrounding and compresses at least three planetary gear (6 and 12), a planetary gear formed with a radial direction and close of the central central shaft (2), of the central shaft of the axial and input/output shaft (1a) alining. The planetary gear (6 and 12) with a central hole, and is rotationally mounted on the shaft part (7 and 13), shaft part (7 and 13) is a central shaft (2) in. At least planetary gear (12) with the planetary gear (12) related shaft part (13) formed as centre; and when the pawnshop star wheel (6) (2) engaged with the central shaft, and other or the planetary gear (6) related and one or more shaft part (7) structure on the central line of the shaft part near the central ring (2) and a distance of distribution than the planetary gear (6) axis. With the so the red torque transmission, the process with the central shaft and one or more planetary gear is the centre to at least two on the pinpointing of the shaft are part of the planetary gear.
