Abstract
The invention relates to a device for guaranteeing the no-axial-power-consumption function of a rotor. The device comprises the casing of a motor, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are arranged on the casing; a rotor shaft is arranged in the casing and extends into the front end cover; an axial automatic control device is arranged on the rotor shaft and mounted in the bearing position in the front end cover; a pair of ball bearings is arranged at the front end and the rear end of the rotor shaft. When the motor runs at a high speed, the inner chambers of the ball bearings at the two ends of the rotor shaft run along with the rotor. Therefore, when the motor is in operation, no axial float and no axial power consumption of the motor are guaranteed.
Description
Technical field
The present invention relates to a kind of wiper motor, the lossless function ensuring equipment of especially a kind of rotor axial.
Background technology
The rotor axial of the motor internal that uses on market is now controlled, with screw, to tighten mutually with pellet at the armature spindle two ends, although can fix the interval of rotor axial, but armature spindle and pellet and the screw of twisting mutually can produce friction and cause a large amount of idle works in the time of machine operation, the phenomenon that makes that the motor feels hot clearly, also can affect to a certain extent the performance of motor, motor its wearing and tearing after high-speed cruising after a while produce increasing gap, make motor cause increasing axial endplay.Therefore need to make improvement to this kind motor, reduce the generation of idle work, improve motor performance.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem that in the above-mentioned background technology, existing wiper motor exists, provide a kind of rotor axial lossless function ensuring equipment.
the technical solution adopted in the present invention is: the lossless function ensuring equipment of a kind of rotor axial, comprise motor case and be arranged on front end housing and the rear end cap on casing, one armature spindle is arranged in casing and gos deep into front end housing inside, on described armature spindle, be provided with axial automatic control equipment, axially automatic control equipment is arranged on the place, position of bearings in front end housing, the front-end and back-end of described armature spindle are provided with a pair of ball bearing, the external diameter circle of front end ball bearing leans against on axial automatic control equipment, the external diameter circle of rear end ball bearing leans against on the rear end cap of casing, in motor case and front end housing assembling, adjusting axial automatic control equipment coincide to casing end face and front end housing end face, motor this moment ball bearing inner chamber at two ends in the process of running up turns round with rotor high-speed.
The invention has the beneficial effects as follows: rotor axial of the present invention lossless function ensuring equipment has overcome the shortcoming that the traditional electrical chance produces a large amount of idle works, motor is on-stream can ensure axial without play can ensure again motor without wasted work.
The accompanying drawing explanation
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
In figure: 1. casing, 2. front end housing, 3. rear end cap, 4. armature spindle, 5. axially automatic control equipment, 6. ball bearing.
Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
the lossless function ensuring equipment of a kind of rotor axial of the present invention as shown in Figure 1, comprise motor case 1 and be arranged on front end housing 2 and the rear end cap 3 on casing 1, one armature spindle 4 is arranged in casing 1 and gos deep into front end housing 2 inside, on described armature spindle 4, be provided with axial automatic control equipment 5, axially automatic control equipment 5 is arranged on the place, position of bearings in front end housing 2, the front-end and back-end of described armature spindle 4 are provided with a pair of ball bearing 6, the external diameter circle of front end ball bearing 6 leans against on axial automatic control equipment 5, the external diameter circle of rear end ball bearing 6 leans against on the rear end cap 3 of casing 1, in motor case 1 and front end housing 2 assemblings, adjusting axial automatic control equipment 5 coincide to casing 1 end face and front end housing 2 end faces, this moment, ball bearing 6 inner chambers at motor two ends in the process of running up turned round with rotor high-speed, the two ends external diameter maintains static, under the effect of axial automatic control equipment, make motor on-stream can ensure axial without play can ensure again motor without wasted work.
Just the specific embodiment of the present invention of describing in above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
