Abstract
The utility model discloses a brush built-in direct-current motor. The brush built-in direct-current motor comprises a housing, a front end cover and a rear end cover which are arranged at two ends of the housing respectively, a motor shaft which is supported between the front end cover and the rear end cover, a rotor which is fixed on the motor shaft, and a stator which is distributed in a manner that the rotor is surrounded by the stator. A brush which is vertical to the motor shaft is located at the rear end cover side. The rear end cover is provided with an annular portion. The annular portion is provided with an insulating gland which is movably compacted onto the brush. According to the utility model, the brush is compacted through the movement of the insulating gland, and the brush can be replaced conveniently only by loosening the insulating gland after the brush is worn, so the advantage of easy operation can be realized, and the working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of brush built-in type direct current motor.
Background technology
In general DC motor structure, brush normally is fixed in casing, uses after brush is worn after a while, need take casing apart the brush of wearing and tearing is changed, and more loaded down with trivial details, operating efficiency is lower.The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of brush built-in type direct current motor is provided,, to simplify brush changing, increase work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of brush built-in type direct current motor, comprise casing, minute be located at front end housing and the rear end cap at casing two ends, the stator that is supported in motor shaft between forward and backward end cap, is fixed on the rotor on motor shaft and is fixed on casing inner wall and distribute around the rotor surrounding, be positioned at the brush that rear end cap one side is provided with the motor vertical axle, described rear end cap has ring part, and ring part is provided with the removable insulation gland that is pressed on brush.
Described ring part is provided with the cutting ferrule that is threaded hole, the insulation gland is located in the screwed hole of cutting ferrule and is threaded with cutting ferrule, the insulation gland has the endoporus of lower ending opening, and brush is positioned at described endoporus, is provided with holddown spring between the insulation gland medial surface of brush and endoporus upper end.
The beneficial effects of the utility model are: the utility model center brush compresses by the movement of insulation gland, after wear of brush,, as long as unclamp the insulation gland, can change easily the brush that has has worn and torn, and is simple to operate, improved operating efficiency.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of brush built-in type direct current motor as shown in Figure 1, comprise casing 1, be respectively equipped with front end housing 2 and rear end cap 3 at casing 1 two ends, motor shaft 4 by bearings between forward and backward end cap 2,3, be fixed with rotor 5 on motor shaft 4, be fixed with the stator 6 that distributes around rotor 5 surroundings at casing 1 inwall, be positioned at rear end cap 3 one sides and be provided with the brush 7 of motor vertical axle 4.
Described rear end cap 3 has a ring part 31, is being provided with the removable insulation gland 8 that is pressed on brush 7 on the wall of ring part 31.
specifically, be provided with the cutting ferrule 9 that is threaded hole on the wall of described ring part 31, insulation gland 8 is located in the screwed hole of cutting ferrule 9 and is threaded with cutting ferrule 9, insulation gland 8 has the endoporus of lower ending opening, brush 7 is positioned at described endoporus, be provided with holddown spring 10 between insulation gland 8 medial surfaces of brush 7 and endoporus upper end, brush 7 be arranged on the insulation gland 8 endoporus in after, the gland 8 that will insulate is threaded with cutting ferrule 9, rely on holddown spring 10 effects in this process, brush 7 is compressed, while needing to change after brush 7 uses and weares and teares, gland 8 withdraws from from cutting ferrule 9 as long as will insulate, can change easily the brush 7 that has damaged.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art can understand content of the present utility model and be implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
