Abstract
The utility model discloses an end cover for a motor of a dust collector, which comprises a cover body provided with a shaft hole, wherein, an annular brace rod is formed on the matching surface of the cover body and a stator core. The existing cylindrical brace rod loaded on the matching surface of the stator core is changed into the annular brace rod, so the end cover greatly strengthens the strength of the brace structure. Thereby, the stable bracing can be provided for the stator core when the motor of the dust collector runs at high speeds; the vibration is effectively prevented; and the operation stability of the motor of the dust collector is greatly enhanced.
Description
Technical field
The utility model relates to a kind of motor of dust collector end cap.
Background technology
Supporting construction contained on the end cap in the present conventional motor of dust collector and the mating surface of stator core mostly is common columnar stays muscle, this class columnar stays muscle is because single intensity difference, add to lack each other and connect and consolidation, cause by the stator core of its carrying structural instability when the motor high-speed cruising, be easy to generate vibration, the normal operation of motor is caused impairment.
Summary of the invention
The utility model purpose is: in order to overcome the deficiency of mentioning in the background technology, and provide a kind of motor of dust collector end cap with high strength stator core supporting construction, can when motor of dust collector runs up, offer the stable support of stator core, prevent its vibration.
The technical solution of the utility model is: a kind of motor of dust collector end cap comprises the lid that has axis hole; Form the annular brace muscle on the mating surface of described lid with stator core.
Go back two locating convex blocks that are formed with symmetry of one on the inwall of the muscle of annular brace described in the utility model, each locating convex block is provided with the locating hole that runs through lid, the same with prior art, these two locating holes are used for wearing screw or bolt, connect with the screwed hole of being located on the stator core, so that the utility model and stator core fixation.The surface of each locating convex block has some projections in the utility model simultaneously, and these projections are with the corresponding coupling of being located on the stator core mating surface of shrinkage pool, to make that further the location is reliable between the utility model and the stator core.
In the utility model on the inner edge of described annular brace muscle being formed with four and being used for the support stator core of one also about the centrosymmetric support face of axis hole, reliable and stable support is provided further for the stator iron core.
On described annular brace muscle, further have two relative wind-guiding gap in the utility model, when assembling motor of dust collector of the present utility model operates, the cooling air from top to bottom that these two wind-guiding gap can effectively guide the motor of dust collector fan to produce is concentrated by the following winding on the stator core, improves the cooling effect of motor of dust collector.
The utility model advantage is:
1. this dust catcher end cap described in the utility model, to originally make the annular brace muscle into columnar stays muscle contained on the stator core mating surface, strengthened the intensity of this supporting construction greatly, thereby can when running up, motor of dust collector offer the stable support of stator core, effectively prevent its vibration, improved the stability of motor of dust collector work greatly.
In the utility model because further being formed with four and can offering the more solid and reliable support of stator core, the stability when further guaranteeing the motor of dust collector running of one on the inner edge of annular brace muscle about the centrosymmetric support face of axis hole.
In the utility model owing to further on the annular brace muscle, have two relative wind-guiding gap, when assembling motor of dust collector of the present utility model operates, the cooling air from top to bottom that these two wind-guiding gap can effectively guide the motor of dust collector fan to produce is concentrated by the following winding on the stator core, improves the cooling effect of motor of dust collector.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the utility model specific embodiment.
Wherein: 1, lid; 2, axis hole; 3, annular brace muscle; 4, locating convex block; 5, locating hole; 6, projection; 7, support face; 8, wind-guiding gap.
The specific embodiment
Embodiment: be illustrated in figure 1 as a kind of specific embodiment of the utility model motor of dust collector end cap, it comprises the lid 1 that has axis hole 2; Form annular brace muscle 3 on the mating surface of described lid 1 with stator core.
Two locating convex blocks 4 that are formed with symmetry of one on the inwall of described annular brace muscle 3, each locating convex block 4 is provided with the locating hole 5 that runs through lid 1; These two locating holes 5 are used for wearing screw or bolt, connect with the screwed hole of being located on the stator core, so that present embodiment and stator core fixation.The surface of described each locating convex block 4 has two projections 6 simultaneously, and these projections 6 are with the corresponding coupling of being located on the stator core mating surface of shrinkage pool, to make that further the location is reliable between present embodiment and the stator core.
Being formed with four and being used for the support stator core about axis hole 2 centrosymmetric support faces 7 of one also on the inner edge of described annular brace muscle 3 provides reliable and stable support further for the stator iron core.
Have two relative wind-guiding gap 8 on the described annular brace muscle 3, when the motor of dust collector of assembling present embodiment operates, the cooling air from top to bottom that these two wind-guiding gap 8 can effectively guide the motor of dust collector fan to produce is concentrated by the following winding on the stator core, improves the cooling effect of motor of dust collector.
The described this dust catcher end cap of present embodiment, to originally make annular brace muscle 3 into columnar stays muscle contained on the stator core mating surface, strengthened the intensity of this supporting construction greatly, thereby can when running up, motor of dust collector offer the stable support of stator core, effectively prevent its vibration, improved the stability of motor of dust collector work greatly.
Simultaneously in the present embodiment since further on the inner edge of annular brace muscle 3 one be formed with four about axis hole 2 centrosymmetric support faces 7, can offer the more solid and reliable support of stator core, the stability when further guaranteeing the motor of dust collector running.
And in the present embodiment owing to further on annular brace muscle 3, have two relative wind-guiding gap 8, when the motor of dust collector of assembling present embodiment operates, the cooling air from top to bottom that these two wind-guiding gap 8 can effectively guide the motor of dust collector fan to produce is concentrated by the following winding on the stator core, improves the cooling effect of motor of dust collector.
