Abstract
The utility model relates to an armature which belongs to the technical field of motor assemblies. A rotating shaft is provided with an iron core stacked by silicon steel sheets and a reverser, wherein the iron core is provided with a winding element; one end of a rotor shaft, closing to the reverser, is provided with a worm in an integrative structure with the rotating shaft. The utility model has the characteristics of high coaxiality of the worm and the rotating shaft, high fit precision of the worm and a gear on the output end of a motor, small noise in operational process, light wear level of the worm and the gear, long service life, etc. The utility model solves the problems in the prior art that the motor armature with the structural requirement hardly ensures the coaxiality of the rotating shaft and the worm, causes low fit precision between the worm and the loaded gear, big noise in operational process and serious abrasion, shortens the service life of equipment, etc.
Description
Technical field
The utility model relates to a kind of armature, belongs to the technical field of electric motor assembly.
Technical background
The motor lead-out wire must be at the axle head that goes out of motor, and motor base of selecting for use and required shaft external diameter are disproportionate, and promptly the external diameter of Motor Shaft is more much bigger than the external diameter of folded punching place of motor.In the prior art, run into the motor of this kind requirement, the designer makes split-type structural with machine shaft and worm screw, both adopt pin or rivet to connect, since the error of processing and assembling, the very difficult axiality that guarantees rotating shaft and worm screw, cause the quality of fit between worm and wheel not high, noise is bigger in the running, and it is comparatively serious to wear and tear, and has shortened the useful life of equipment.
The axial location of commutator and rotating shaft then adopts axle sleeve etc., and it is unreliable that this location structure exists the location, has reduced the operational reliability of motor.
Summary of the invention
The utility model provides the axiality height of a kind of worm screw and rotating shaft, the quality of fit height of the worm and wheel of motor output end, noise is less in the running, the degree of wear of worm and gear is lighter, the armature that useful life is long, solved the very difficult axiality that guarantees rotating shaft and worm screw of the armature of this kind structural requirement motor in the prior art, cause the quality of fit between the worm gear of worm screw and load not high, noise is bigger in the running, it is comparatively serious to wear and tear, and has shortened the problems such as useful life of equipment.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: rotating shaft is provided with iron core and the commutator that is built up by silicon steel sheet, the element of winding is arranged on the iron core, armature spindle is provided with worm screw near an end of commutator, and described worm screw and rotating shaft are integral structure.Transmission component and rotating shaft are adopted an axle one processing, can guarantee the axiality of rotating shaft and worm screw well, improved the reliability of transmission between rotating shaft and transmission component on the one hand, on the other hand, can improve the quality of fit between the worm gear of worm screw and load greatly, reduce the noise in the engagement process, reduced wearing and tearing therebetween, prolonged their useful life.
As preferably, be provided with pillow block between described worm screw and the commutator, end face of this pillow block and an end face of commutator offsets and with rotating shaft be integral structure; The diameter at described pillow block place be described rotating shaft with the 1.5-2 of the cooperation place unshakable in one's determination diameter that builds up by silicon steel sheet doubly.Axial positioning structure between commutator and rotating shaft is designed to pillow block with the rotating shaft integral structure, increased the reliability that cooperates between commutator and rotating shaft, improved the motor reliability of operation.
Therefore, the utlity model has the axiality height of worm screw and rotating shaft, the quality of fit height of the worm and wheel of motor output end, noise is less in the running, and the degree of wear of worm and gear is lighter, and useful life is than characteristics such as length.Transmission component and rotating shaft are adopted an axle one processing, can guarantee the axiality of rotating shaft and worm screw well, improved the reliability of transmission between rotating shaft and transmission component on the one hand, on the other hand, can improve the quality of fit between the worm gear of worm screw and load greatly, reduce the noise in the engagement process, reduced wearing and tearing therebetween, prolonged their useful life.Axial positioning structure between commutator and rotating shaft is designed to pillow block with the rotating shaft integral structure, increased the reliability that cooperates between commutator and rotating shaft, improved the motor reliability of operation.
