Abstract
The utility model discloses an axial positioning structure of a water pump motor rotor. The motor comprises a motor cylinder, one end of the motor cylinder is sealed, and the other end of the motor cylinder is open, an oil cylinder cover is disposed on the opening end. A rotor shaft of the motor goes through the oil cylinder cover, a bearing is disposed between the rotor shaft and the oil cylinder cover. A stop opening is disposed on the rotor shaft at the internal side of the bearing, and a clamping spring is disposed on the rotor shaft at the external side of the bearing. A groove which cooperates with the bearing is disposed on the oil cylinder cover, the rotor shaft goes through the groove, and the opening part of the groove is provided with a clamping board which is used for fixing the bearing in a pressing manner. With the axial positioning structure, good axial stability of the rotor is obtained, and the service life of the water pump motor is guaranteed.
Description
Technical field
The utility model relates to a kind of axial positioning structure, relates in particular to a kind of pump motor rotor axial location structure.
Background technology
The structure of pump motor comprises motor cylinder, is provided with coaxially rotor and stator in motor cylinder, and the center position of rotor is provided with armature spindle.One end sealing of motor cylinder, other end opening, need to arrange oil cylinder cover at the openend of motor cylinder, so that an airtight cavity of the inner formation of motor cylinder injects lubricating oil with tank.The outer end of armature spindle is through oil cylinder cover, and inner end is rotatably supported in the blind end of motor cylinder, between the two ends of armature spindle and motor cylinder, all needs to arrange bearing.Water pump is in the time of work, because rotor needs to rotate, armature spindle should be subject to footpath power upwards, power on being subject to again axially, after the power of armature spindle on being subject to axially, can act directly on bearing, therefore, the axial location between bearing and motor cylinder is related to the stability of working rotor, and the axial location stability that is particularly arranged on oil cylinder cover place bearing is even more important to the job stability of rotor.Existing pump motor is because the axial location stability at oil cylinder cover place can not guarantee, the phenomenon that pump motor is easily damaged in the course of the work.
Summary of the invention
For overcoming above-mentioned defect, the utility model technical issues that need to address are: a kind of pump motor rotor axial location structure is provided, and this location structure can effectively guarantee the axial location stability of oil cylinder cover place bearing, can effectively improve the useful life of water pump.
For solveing the technical problem, the technical solution of the utility model: a kind of pump motor rotor axial location structure, described motor comprises motor cylinder, the sealing of motor cylinder one end, other end opening, be provided with oil cylinder cover at this openend, armature spindle in motor, through oil cylinder cover, is provided with bearing between armature spindle and oil cylinder cover, it is characterized in that, on armature spindle in the interior distolateral seam that is provided with of bearing, on armature spindle in the outer distolateral jump ring that is provided with of bearing; On oil cylinder cover, be provided with the pit for matching with bearing, armature spindle, through pit, is provided with the clamp for bearing is pressed solidly at the oral area of pit.Oil cylinder cover is generally to realize fixing with motor nozzle portion by fastening bolt, described pit can be arranged on to the medial surface of oil cylinder cover, utilizes the blind end of oil cylinder cover and motor cylinder and from the both sides of armature spindle, armature spindle is clamped.
Described clamp is circular, and armature spindle is through clamp.
In bearing outer ring, distolateral outer rim is provided with the L-shaped breach of truncation surface, and the interior oral area of clamp is plugged in this breach.
In the interior distolateral one-body molded plush copper that has of oil cylinder cover, described pit is formed in plush copper, and the outer face of bearing and the bottom surface of pit fit.
The beneficial effects of the utility model are: due to described pit can be set on the medial surface of oil cylinder cover, can utilize oil cylinder cover and motor cylinder blind end from both sides, two bearings on armature spindle to be gripped, on armature spindle, be provided with in addition described seam, bearing is pressed close to mutually with seam, the bearing at oil cylinder cover place has good axial location stability, there is good axial location stability at the bearing at motor cylinder blind end place itself, thereby this has guaranteed the axial stability of armature spindle, armature spindle good stability in the course of the work, guarantee the useful life of motor.The clamp arranging is spacing for the bearing in depression is carried out, and this bearing is remained in depression well, and this bearing is realized tight fit between can not needing and cave in, thus the convenient assembling to motor.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view with the pump motor of this rotor axial location structure.
Embodiment
See in figure, the utility model pump motor rotor axial location structure is arranged on pump motor, the structure of motor comprises the motor cylinder 1 of hollow, one end sealing of motor cylinder 1, the other end is opening, be fixed with oil cylinder cover 5 at this opening part by fastening bolt 4, thus make motor cylinder 1 inner form a sealing, for containing the cavity of lubricating oil.In motor cylinder 1, be provided with coaxially rotor 8 and stator 9, rotor 8 and stator 9 are immersed in the lubricating oil in motor cylinder 1.
Be provided with armature spindle 10 at the center position of rotor 8, the inner end of armature spindle 10 is bearing in the blind end place of motor cylinder 1 by bearing 7, and oil cylinder cover 5 is passed in the outer end of armature spindle 10, and reaches the outside of oil cylinder cover 5, and the outer end of armature spindle 10 is fixed with impeller.
Between armature spindle 10 and oil cylinder cover 5, be provided with bearing 7, specifically one-body molded on the inner face of oil cylinder cover 5 have a plush copper, is provided with pit in plush copper, utilizes plush copper to be plugged in the opening of motor cylinder 1, and make the assembling between oil cylinder cover 5 and motor cylinder 1 stable.The bearing 7 of being located at oil cylinder cover 5 positions is arranged in pit, and the outer face of this bearing 7 and the end of pit fit mutually.At the outer distolateral seam that is formed with of armature spindle 10, inner face and this seam of the bearing 7 of oil cylinder cover 5 positions fit, on armature spindle 10, be provided with jump ring 6 in the outside of this bearing 7, jump ring 6 and seam coordinate for limiting the axial location of this bearing 7 on armature spindle 10.
Be provided with clamp 3 at the oral area of pit, ringwise, clamp 3 is socketed on armature spindle 10 this clamp 3, and clamp 3 is fixed on the oral area of pit by fastening bolt 2, on the inner face of described plush copper.The outer rim place of oil cylinder cover 5 position bearing 7 the inners, outer ring is provided with the L-shaped breach of truncation surface, and breach is annular, and it extends along the whole outer rim of these bearing 7 outer rings, and the interior oral area of clamp 3 is plugged in this breach.After the interior oral area of clamp 3 is plugged in this breach, can, for the bearing 7 at oil cylinder cover 5 places provides the effect of pressing solidly, also make the fitment stability between clamp 3 and this bearing 7 good on the one hand simultaneously.
