MULTI-STAGE PLANETARY REDUCTION GEAR

摘要

1. A multi-stage planetary reduction gear in which the planetary carrier (5) of the first stage (1) is drivingly connected to the sun gear (11) of the following stage (2) by means of a splined shaft connection, wherein the planetary carrier (5) of the first stage is arranged floatingly and is provided with a neck (9) which is connected to the sun gear (11) of the following stage (2) and located closely to said sun gear, and wherein in the following stage (2) the sun gear (11) is arranged floatingly, the planetary carrier (13) of the last stage runs on rigidly mounted bearings and the ring gear (8, 15) is rigidly connected with the gearbox case (16), characterized in that the planetary carrier (5) of the first state (1) is connected to the sun gear (11) of the following stage (2) in a per se known manner by means of a denture clutch (9, 10) whereat sun gear (11) and planetary carrier (5) can float relative to each other, wherein he neck (9) of the floatingly arranged planetary carrier (5) of the first stage (1) had the internal denture of the denture clutch (9, 10) and wherein the floatingly arranged planetary carrier (5) in a per se known manner has planet pinion gears (6) running on self-aligning bearings.
