Abstract
A planetary transmission slewing mechanism comprises a motor and is characterized by further comprising a coupler, a multi-piece friction brake, a multi-stage planetary deceleration mechanism and an output gear shaft. The motor is connected with a spindle through the coupler which is provided with the multi-piece friction brake, the spindle is provided with a sun wheel of the multi-stage planetary deceleration mechanism, and an output end of the multi-stage planetary deceleration mechanism is provided with a planet carrier which is connected with the output gear shaft through a spline. The planet carrier of the multi-stage planetary deceleration mechanism is provided with a suspension arm which is provided with a planet wheel through a non-outer-ring bearing. The multi-piece friction brake enables the braking of a travelling mechanism to be reliable. The sun wheel and the planet wheel are both in full floating structures, and accordingly the loading of the two wheels is even. The planet carrier adopts a suspension arm structure to enable the axial dimension of the slewing mechanism to be compact, and the planet wheel bearing adopts the non-outer-ring structure to enable the radial direction of the slewing mechanism to be small.
Description
Technical field
The utility model relates to a kind of swirl gear of engineering machinery.
Background technique
The slew gear that is applied to engineering machinery at present adopts worm and gear or cycloidal-pin wheel transmission more, and above-mentioned two kinds of slew gear volumes are big, Heavy Weight, torque transmission capacity are little.
The model utility content
In order to overcome the shortcoming that above-mentioned existing technology exists, the purpose of the utility model is to provide a kind of Gear Planet Transmission swirl gear, and the load of its compact dimensions, two-wheeled is even.
In order to address the above problem; The utility model adopts following technological scheme: this Gear Planet Transmission swirl gear; Comprise motor; Also comprise coupling, multidisc friction brake, multistage planet reducing gear, output gear shaft, said motor connects a main shaft through coupling, assembling multidisc friction brake on the said coupling; The sun gear of multistage planet reducing gear is set on the main shaft, and the output terminal of multistage planet reducing gear is a planet carrier; Planet carrier connects an output gear shaft through spline; Planet carrier in the multistage planet reducing gear is provided with cantilever, and said cantilever is through no outer shroud Bearing Installation planet wheel.
The beneficial effect of the utility model is:
1, adopt the multidisc friction brake to make the traveller braking reliable.
2, sun gear, planet wheel adopt the full floating structure, make the load of two-wheeled even.
3, planet carrier adopts cantilever structure to make the swirl gear axial dimension compact.
4, planet wheel bearing adopts the outer ring structure of nothing to make the swirl gear radial dimension little.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the utility model embodiment's a structural representation;
Among the figure: 1 motor, 2 coupling, 3 multidisc friction brakes, 31 pistons, 32 springs, 4 sun gears, 5 planet wheels, 6 planet carriers, 8 do not have outer collar bearing, 9 main shafts, 10 output gear shafts.
Embodiment
As shown in Figure 1; This Gear Planet Transmission swirl gear comprises motor 1; Also comprise coupling 2, multidisc friction brake 3, multistage planet reducing gear, output gear shaft 10, said motor 1 connects a main shaft 9 through coupling 2, assembling multidisc friction brake 3 on the said coupling 2; The sun gear 4 of multistage planet reducing gear is set on the main shaft 9, and the output terminal of multistage planet reducing gear is a planet carrier 6; Planet carrier 6 connects an output gear shaft 10 through spline; Planet carrier in the multistage planet reducing gear is provided with cantilever, and said cantilever is not installed planet wheel 5 through there being outer collar bearing 8.
Act on through pressure oil on the piston 31 of multidisc friction brake; Open multidisc friction brake 3; When motor 1 power is passed to coupling 2, through coupling 2 power is passed to sun gear 4 again, sun gear 4 is passed to planet wheel 5 with power; Planet wheel 5 is passed to planet carrier 6 with power, the rotation of planet carrier 6 usefulness splined output gear shafts 10 driving devices.
When removing the pressure oil that acts on the piston 31, piston 31 is closed multidisc friction brake 3 under the effect of spring 32, and coupling 2 is stopped to rotation, thereby realizes the swirl gear braking.
All the other technology are known technology.
