The utility model discloses a reduction motor comprising a motor shell, wherein a stator and a rotor are mounted in the motor shell; a fixed annular gear is further arranged in the motor shell; a sun gear is connected to the rotor; a planet gear engaged with the sun gear and the annular gear is arranged on the planet carrier in the motor shell; and an output shaft is fixedly connected to the planet carrier. By organically and fixedly combining the motor and a reduction mechanism into a whole, the utility model has the advantages of good assembly manufacturability, lower weight, smaller size and convenient use and increases the concentricity of the motor in the operation; moreover, the utility model further improves the overall performance of the motor.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of reducing motor.
Background technology
At present, guardrail in the middle of being equipped with on the highway in city, cities and towns, the road, be used to safeguard vehicle and pedestrian's traffic order and safety, because road is seriously polluted, dust is many, after a period of time, just can speckle with a large amount of dusts and booty on guardrail, greatly influence the attractive in appearance of city, also influenced the useful life of guardrail.
The basal conditions of guardrail cleaning now is: adopt the automobile Cleaning vehicle for guardrail to clean, comprising cleaning brush mechanism, cleaning brush mechanism can realize passing in and out and lifting in car body, after cleaning brush mechanism stretches out outside the car body, the preceding brush of cleaning brush will be realized upwards upset, come to make the back brush near guardrail, again by the rotation of fluid motor-driven cleaning brush, the rotation by the front and back brush realizes the cleaning to guardrail.But the structure more complicated of hydraulic system causes the structure of cleaning brush mechanism to become complicated, and volume increases, so cleaning brush mechanism can not shrink in the car body fully, it is bigger not only to take path space, and not attractive in appearance, pollutes cleaning brush easily.Adopt the rotation of motor-driven cleaning brush, compare power source part and control circuit with hydraulic motor and want simple many, but all such driving mechanism to be installed on every cover cleaning brush, motor need drive cleaning brush afterwards by the reductor speed change, motor connects by shaft coupling with reductor, one independently motor add independently a reductor and a shaft coupling again, this combined volume and weight are all bigger, be unfavorable for the installation on the cleaning brush support, particularly preceding cleaning brush is to hang on the outside, therefore needs the stronger telescoping mechanism of counter-bending ability.So the driving that present motor and speed reducer constitutes, though control system is simpler than hydraulic motor, the volume and weight of motor plus-minus band machine than big many of hydraulic motor, is the protection axiality again when connecting by shaft coupling in addition, and join operation is relatively more difficult.Therefore, provide a kind of motor simple in structure, that volume is little to help simplifying Cleaning vehicle for guardrail and reduction energy resource consumption.
The utility model content
At the complicated in mechanical structure that exists in the prior art, bulky problem, the purpose of this utility model is to provide a kind of reducing motor, this motor simple in structure, and volume is little, thereby has simplified the structure of entire mechanism, makes smaller volume.
The technical solution of the utility model is achieved in that a kind of reducing motor, comprise housing, stator and rotor are housed in the housing, the housing inboard is provided with fixing ring gear, connect sun gear on the rotor, the planetary gear that is meshed with sun gear and ring gear is arranged on the planet carrier in the housing, is fixed with output shaft on the planet carrier.
Preferably, described planet carrier and output shaft are structure as a whole.
Preferably, described output shaft is a hollow shaft, and described sun gear is mounted on the armature spindle, and insert in the described hollow output shaft armature spindle end, between hollow output shaft and the armature spindle and between hollow output shaft and the described housing bearing is housed all.
Preferably, described hollow output shaft spindle nose adopts the external diameter spindle nose that contracts.
Preferably, described housing comprises platen and following platen, and last platen is connected with bolt by concavo-convex flange with following platen, and described ring gear, sun gear and planetary gear and planet carrier are the cavitys that is positioned at platen and following platen formation.
Preferably, described ring gear and electric machine casing are structure as a whole.
Preferably, be provided with a motor loam cake on the described electric machine casing.
The beneficial effects of the utility model are: in the utility model with the rotor of motor, the motor assembly that stator constitutes and by sun gear, planetary gear, the planet-gear speed reducer assembly that ring gear constitutes is combined as a whole and is assemblied in the set of shells, to compare assembly process process good with motor and speed reducer independently, make the concentricity of motor and speed reducer in operation process improve, also improved the overall performance of motor in addition, and weight saving, smaller volume, the convenient use, be particularly suitable for the traffic guardrail cleaning Vehicle, especially be situated between as the rotational driving device use of the cleaning brush on the traffic guardrail cleaning Vehicle.This motor also can be applied to other needs little, the lightweight field of volume and mechanically.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Among the figure: 1 housing, platen on 2,3 ring gears, 4 times platens, 5 planetary gears, 6 output shafts, 7 sun gears, 8 motor loam cakes, 9 bearings, 10 spindle noses, 11 stators and rotor combination, 12 armature spindles.
Embodiment
In conjunction with the accompanying drawings the utility model is described further:
As shown in Figure 1, a kind of reducing motor, this motor are the combination of a direct current motor and reducing gear, comprise output shaft 6 and electric machine casing 1, wherein, stator and rotor combination 11 are housed in the electric machine casing 1, constitute motor assembly.In housing, also be integrated with the reductor assembly, reductor adopts the planetary gear reducing gear, this mechanism comprises ring gear 3, sun gear 7 and the planetary gear 5 that is meshed with sun gear 7 and ring gear 3, ring gear 3 is fixed on electric machine casing 1 inboard, ring gear 3 can also be an integral structure with electric machine casing 1, sun gear 7 is installed on the armature spindle 12, and planetary gear 5 is arranged on the planet carrier of output shaft 6 end one.
The spindle nose of output shaft 6 adopts the external diameter spindle nose 10 that contracts, and this undergauge spindle nose 10 can be installed the round brush of Cleaning vehicle for guardrail easily at axle head.
Housing removes and comprises the tubular electric machine casing part that stator and roller are installed, and also comprises platen 2 and following platen 4, and last platen 2 is connected with bolt by concavo-convex flange with following platen 4, adopts concavo-convex flange to be convenient to concentric fits and sealing.Ring gear, sun gear and planetary gear and planet carrier are the cavitys that is positioned at platen 2 and following platen 4 formations, are convenient to the I﹠ M of planetary gear reducing mechanism like this.
