Abstract
The invention relates to a motor structure, in particular to a motor structure with an automatic axial-endplay adjustment function, and belongs to the technical field of motors. The motor structure comprises a rear end cap and an armature in a front end cap; the part of the armature disposed in the front end cap is connected with plane washer, a saddle washer and a gear in a sliding manner sequentially; the plane washer and the saddle washer together compress the gear. The motor structure is simple, compact and reasonable, is easy to assemble, is free of clearance due to the fact that the saddle washer can realize automatic clearance adjustment within a certain range, and is low in cost since no adjusting washer is needed. With the motor structure, motor reliability is improved while assembling efficiency is increased.
Description
Technical field
The present invention relates to a kind of electric motor structure, 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 object of the invention is to overcome above-mentioned weak point, thereby provide a kind of axial motion self-adjusting electric motor structure, adopt saddle shaped washer automatic regulating gap within the specific limits, make it reach zero clearance, improved efficiency of assembling.
According to technical scheme provided by the invention, 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 present invention has the following advantages:
The present invention 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 structural representation of the present invention.
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 present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention 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.
