Abstract
The utility model relates to a motor structure, specifically relates to an axial endplay automatic adjustment motor structure and belongs to the motor technology field. The axial endplay automatic adjustment motor structure comprises an armature which is arranged both in a back end cover and a front end cover, wherein the part of the armature which is in the front end cover is in sliding connection with a plain washer, a saddle type washer and a gear sequentially, and the plain washer and the saddle type washer compact the gear tightly. The axial endplay automatic adjustment motor structure has a simple, compact and reasonable structure and employs the saddle type washer to carry out automatic gap adjustment to a certain degree to realize zero gap; no extra adjustment pad is required, so cost is reduced; reliability of the motor is improved, assembly efficiency is improved, and the axial endplay automatic adjustment motor structure is simple and easy to assemble.
Description
Technical field
The utility model relates to a kind of electric motor structure, and the self-adjusting electric motor structure of a kind of axial motion, belongs to motor technology field specifically.
Background technology
There is axial motion in series-wound motor, and the vibration size of every motor is inconsistent, need to adjust axial motion by increasing appropriate adjustment pad in the time of assembling, and this has increased assembly difficulty just to motor assembler, has also reduced efficiency of assembling simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of axial motion self-adjusting electric motor structure, adopts saddle shaped washer automatic regulating gap within the specific limits, makes it reach zero clearance, has improved efficiency of assembling.
The technical scheme providing according to the utility model, the self-adjusting electric motor structure of axial motion comprises the armature that is positioned at rear end cap and front end housing, armature front end is arranged in front end housing by front end housing bearings, and the rear end of armature is supported and is arranged in rear end cap by bearing of rear end cover; Between described rear end cap and front end housing, be bolted stator, stator is positioned at armature outer ring, it is characterized in that: described armature is positioned at front end housing part be slidably connected successively plain washer, saddle shaped washer and gear, and plain washer and saddle shaped washer compress gear.
Further, on bolt, attaching nut locks rear end cap, stator and front end housing.
Further, gear one end is provided with the location notch of U-shaped, is provided with the alignment pin that connects armature in location notch.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, adopts saddle shaped washer automatic regulating gap within the specific limits, makes it reach zero clearance; Adjust pad without increasing, reduced cost; Improve motor reliability, improved efficiency of assembling; Assemble simple.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-rear end cap, 2-bearing of rear end cover, 3-nut, 4-stator, 5-bolt, 6-armature, 7-plain washer, 8-saddle shaped washer, 9-gear, 10-front end housing bearing, 11-front end housing, 12-location notch, 13-alignment pin.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises the armature 6 that is positioned at rear end cap 1 and front end housing 11, and armature 6 front ends are supported and are arranged in front end housing 11 by front end housing bearing 10, and the rear end of armature 6 is supported and is arranged in rear end cap 1 by bearing of rear end cover 2.
Between described rear end cap 1 and front end housing 11, by bolt 5 connecting stators 4, stator 4 is positioned at armature 6 outer rings.On described bolt 5, attaching nut 3 locks rear end cap 1, stator 4 and front end housing 11.
Described armature 6 is positioned at front end housing 1 part be slidably connected successively plain washer 7, saddle shaped washer 8 and gear 9, and plain washer 7 and saddle shaped washer 8 compress gear 9.Gear 9 one end are provided with the location notch 12 of U-shaped, are provided with the alignment pin 13 that connects armature 6 in location notch 12, and alignment pin 13 is the position on armature 6 for fixed gear.
Bearing of rear end cover 2 outer faces are L1 to the distance of stator 4, and stator 4 length are L2, and front end housing bearing 10 outer faces are L3 to the distance of stator 4, total length L 0=L1+L2+L3.Therefore the distance L of two bearing two outer faces=(L1+L2+L3).In the time of L<L0, will there is axial motion in motor; In the time of L>L0, motor axial motion will be adjusted to 0 automatically, and saddle shaped washer 8 automatic regulating gap within the specific limits makes it reach zero clearance.
