Abstract
The invention discloses a duplex type supporting clearance automatic compensation structure of a motor rotor, comprising a positioning structure and a compensation structure. The positioning structure comprises a sleeve, a gland, an angular contact ball bearing and an spacer bush, wherein the sleeve is sleeved between an end cap inner bore and a rotor shaft and is locked through a round nut, and the angular contact ball bearing is installed with a big conical end facing outward. The compensation structure is arranged between two outer rings of the angular contact ball bearing and is formed by uniformly and axially arranging pressure springs between an annular flat gasket and a seat cushion. By using the elastic tension of the springs to push the seat cushion and the flat gasket which is in clearance fit with the end cap to move axially, the outer rings of the angular contact ball bearing are automatically jacked so as to ensure that the angular contact ball bearing is in zero clearance fit, thereby effectively improving the rotation quality of the support of the motor rotor and reducing rotation noises.
Description
Technical field
The present invention relates to the compound supported clearance of a kind of rotor and adjust structure, the structure of the compound supported clearance of particularly a kind of automatic small electromotor rotor.
Background technology
Motor rotates the mechanical abrasion that produces and mainly concentrates on the rotor bearing, and the rotor bearing of wearing and tearing must reduce the rotor rotation precision and increase rotational noise if can not get effective compensation.The motor bigger to service load becomes duplex with the rotor support design usually, and two angular contact ball bearings that direction is opposing promptly are installed on same supporting point.For the gap of play between the inside and outside circle of angular contact ball bearing and rotation wearing and tearing generation, prior art is regulated by the gland axial location and is eliminated.But this structure can only can realize just by manual adjustment under stopped status that the structure that seems during practical application is unreasonable, and it is convenient inadequately to regulate, and promptness is relatively poor.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, proposes a kind of simple in structure, compensation in time, the compound supported clearance automatic compensation structure of the rotor of even regulation.
The present invention is achieved through the following technical solutions technical goal.
The compound supported clearance automatic compensation structure of rotor, it comprises location structure and collocation structure.Described location structure comprises suit between end cap endoporus and the armature spindle, and cover, gland, angular contact ball bearing and spacer by round nut locking, and angular contact ball bearing is installed outwardly with the big end of circular cone.Its improvements are: described collocation structure is between two angular contact ball bearing outer rings, and it is made of jointly the column spring of uniform axial installation between the annular plain cushion of parallel installation and the seat cushion.
In the said structure, spring is a compression spring, and spring is the ring-type plain cushion of the parallel installation of basic roof pressure with seat cushion.Plain cushion and seat cushion outer wall and end cap endoporus matched in clearance.
The present invention compared with prior art has following good effect:
1, elastic compensating is simple in structure, makes easily;
2, the elastic compensating structure is done uninterrupted compensation, and the compensation promptness is good, makes rotor bearing remain the best fit state, and rotation precision height, noise are low;
3, the elastic compensating structure that is in place need not shut down and be made the artificial angular contact ball bearing fit clearance of adjusting, and saves cost of upkeep.
Description of drawings
Accompanying drawing is a structural profile schematic diagram of the present invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Be structural representation of the present invention shown in the accompanying drawing, it is the motor embodiment of horizontal type structure, comprises location structure and collocation structure two parts altogether.Described location structure comprises suit between end cap 8 endoporus and the armature spindle 1, and cover 3, gland 4, angular contact ball bearing 5 and spacer 7 by round nut 2 locking, be separated by by spacer 7 between the angular contact ball bearing 5, spacer 7 rotates with axle 1 between two angular contact ball bearing 5 inner rings, and the big end of the taper hole of two angular contact ball bearings 5 outwardly.Described collocation structure is between two angular contact ball bearing 5 outer rings, it is made of jointly the column spring 9 of uniform axial installation between the annular plain cushion 6 of parallel installation and the seat cushion 10, spring 9 is a compression spring, utilize spring 9 elasticity tensions to promote to move axially with the plain cushion 6 and the seat cushion 10 of end cap 8 matched in clearance, make it the outer ring of automatic roof pressure angular contact ball bearing 5, guarantee that angular contact ball bearing 5 is in no gap all the time and cooperates.This elastic compensating structure can compensate automatically in motor operation course and in time compensate the supporting abrasion gap, effectively improves rotor supporting rotating mass, alleviates rotational noise.
