Description
Technical field
The utility model motor belongs to the technical field that rotor is axially located, particularly the technical field of rain shaving electrical machine rotor axial location.
Background technology
Current wiper motor rotor axial location is all adopt middle part processing two stopper slots, fix rolling bearing with two jump rings and utilize spring bearer plate to be rigidly attached on deceleration box, utilizing deceleration box screwed hole to assist trip bolt and steel-ball limiting rotor axial gap at rotor head.Rotor axially location employing is rigidly connected, and the slight jitter that rotor produces in the process of running up can utilize the deceleration box transmission amplify and cause motor vibrating probability to increase of being rigidly connected; Due to the machining tolerance of armature spindle two stopper slots, the dimensional tolerance of jump ring itself, make rotor really cannot eliminate end play, motor in the course of the work rotor has the possibility of axial endplay.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of New-type electric machine, and this New-type electric machine utilizes gap telescopic spring to produce flexible feature, eliminates the gap that the part such as rotor, jump ring causes in the tolerance of process and assemble.
The purpose of this utility model is achieved through the following technical solutions:
A kind of New-type electric machine, comprise trip bolt (1), the first jump ring (2), deceleration box (3), rolling bearing (4), spring bearer plate (5), gap spring (6), rotor (7), bearing (8), the second jump ring (9), armature spindle (10), it is characterized in that: gap spring (6) two ends are fixedly connected with spring bearer plate (5) right side outer surface, the second jump ring (9) left outer surface respectively, and the first jump ring (2) and the second jump ring (9) are buckled on armature spindle (10) respectively.
Described spring bearer plate (5) and rolling bearing (4) left outer surface are close to, gap spring (6) one end is fixedly connected on spring bearer plate (5), gap spring (6) other end is fixedly connected with the second jump ring (9), and rolling bearing (4) and the first jump ring (2) are close to.
Described rolling bearing (4) is fixedly connected with deceleration box (3).
Described first jump ring (2) is buckled in top, armature spindle (10) left side, and the second jump ring (9) is buckled in top, armature spindle (10) right side.
By above-mentioned the technical solution of the utility model, the utility model is very effective solve rotor axially location employing be rigidly connected, the slight jitter that rotor produces in the process of running up can utilize the deceleration box transmission amplify and cause motor vibrating probability to increase of being rigidly connected; Due to the machining tolerance of armature spindle two stopper slots, the dimensional tolerance of jump ring itself, make rotor really cannot eliminate end play, motor in the course of the work rotor has the problem of the possibility of axial endplay.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is gap of the present utility model spring structure schematic diagram;
In figure:
1, trip bolt; 2, jump ring; 3, deceleration box; 4, rolling bearing; 5, spring bearer plate; 6, gap spring; 7, rotor; 8, bearing; 9, jump ring; 10, armature spindle.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
As shown in Figure 1, trip bolt (1), deceleration box (3), rolling bearing (4), rotor (7), bearing (8) are conventional motors structure.Rotor (7) has axial force generation at rotary course and causes rotor to have axial endplay, and by extruding, rolling bearing (4) and gap spring (6) are stuck on armature spindle (10) by the first jump ring (2) and the second jump ring (9), by spring bearer plate (5), rolling bearing is fixed on (3) on deceleration box again, rotor head trip bolt (1) carries out normal direction supplemental support, afterbody adopts bearing (8) to carry out supplemental support, and rotor (7) is operated in the state of the equilibrium normally.
As shown in Figure 2, rolling bearing (4), spring bearer plate (5) make gap spring (6) shrink and keep stress balance by extruding by the first jump ring (2) and the second jump ring (9), keep rotor (7) to balance at the volley by gap spring (6) tension force.
In use, rotor operates in the state of the equilibrium normally, utilizes the flexible resilient feature of gap spring, keeps gap spring to be in pressured state for the gap of eliminating rotor, the tolerance of jump ring process and assemble causes.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
Claims (4)
1. a New-type electric machine, comprise trip bolt (1), the first jump ring (2), deceleration box (3), rolling bearing (4), spring bearer plate (5), gap spring (6), rotor (7), bearing (8), the second jump ring (9), armature spindle (10), it is characterized in that: gap spring (6) two ends are fixedly connected with spring bearer plate (5) right side outer surface, the second jump ring (9) left outer surface respectively, and the first jump ring (2) and the second jump ring (9) are buckled on armature spindle (10) respectively.
