Abstract

The invention relates to a planetary transmission swinging mechanism which comprises a motor. The mechanism is characterized by also comprising a coupler, a multi-plate-type friction brake, a multi-stage planetary speed reducing mechanism and an output gear shaft; the motor is connected with a main shaft through the coupler; the multi-plate-type friction brake is assembled on the coupler; the main shaft is provided with a sun wheel of the multi-stage planetary speed reducing mechanism; the output end of the multi-stage planetary speed reducing mechanism is a planetary frame; the planetary frame is connected with an output gear shaft through a spline; the planetary frame of the multi-stage planetary speed reducing mechanism is provided with a suspending arm; and the suspending arm is provided with a planetary wheel through an outer-ring-free bearing. The brake of a walking mechanism is reliable by adopting the multi-plate-type friction brake; a full-floating structure is adopted for the sun wheel and the planetary wheel, thus the loadings of the two wheels are uniform; the suspending arm structure is adopted for the planetary frame, thus the axial size of the swing mechanism is compact; and the outer-ring-free structure is adopted for the planetary wheel bearing, thus the radial size of the swinging mechanism is smaller.

Description

technical field [0001] The invention relates to a rotary mechanism of construction machinery. Background technique [0002] At present, most of the rotary mechanisms used in construction machinery are driven by worm gears or cycloidal pinwheels. The above two rotary mechanisms are large in size, heavy in weight, and small in torque transmission capacity. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the object of the present invention is to provide a planetary transmission slewing mechanism, which is compact in size and has uniform loads on the two wheels. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: the planetary transmission slewing mechanism includes a motor, and also includes a coupling, a multi-plate friction brake, a multi-stage planetary reduction mechanism, and an output gear shaft. A main shaft is connected, and the coupling is equipped w...
