Abstract

The invention discloses a power shunt type combined planetary reducer which comprises an input gear pair, a differential planet gear pair, a closed planet gear pair arranged between the input gear pair and the differential planet gear pair, a flexible shaft and a supporting rod. In the invention, only the supporting rod is grounded through a torque stand mechanism, and the torque stand mechanism can absorb vibration, angular deviation and displacement generated when a mill operates and can not influence gears and bearings, thereby prolonging the service life of components; and the planet rotating stand of the differential planet gear pair is an output flange for transferring a small part of torque, and the closed inner gear ring of the closed planet gear pair is connected with the output flange for transferring a large part of torque, i.e. the output flange and the closed inner gear ring are used for outputting the torque together in a shunt way. The power shunt type combined planetary reducer is more safe and reliable, has compact structure, small volume and light weight and saves a large amount of manufacturing cost. By adopting the direct connection mode of the output flange, atransmission shaft is omitted, thereby having the advantages of light weight and compact structure, greatly shortening the arrangement size and reducing the construction investment of a factory building.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a power split type combined planetary speed reducer with high power, high speed ratio and small volume. Background technique [0002] At present, the center drive reducer is generally a power double split, two-stage reduction, symmetrical arrangement, and coaxial structure. The main motor is connected to the first-stage pinion shaft of the main reducer through a coupling, and the first-stage pinion gear meshes with the two large gears to complete the first-stage deceleration; the first-stage large gear is connected to the second-stage pinion through a flexible shaft , the secondary pinion gear meshes with the large gear for secondary deceleration and transmits the torque to the mill. The disadvantage is that the process layout occupies a large area, the cost is high, and the cycle is long. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention ...
