Abstract
The utility model discloses a retainer ring for a motor. The retainer ring is characterized in that the retainer ring is made of an epoxy glass cloth board. An annular step concentric with the retainer ring is arranged on the inner edge of the retainer ring, a plurality of axial through holes are formed in the outer edge of the retainer ring circumferentially and evenly, and a plurality of annular grooves concentric with the retainer ring are further formed in the inner wall of the retainer ring. Due to the fact that the retainer ring is made of the epoxy glass cloth board, the retainer ring has good insulation performance and high mechanical strength. The middle of the retainer ring is annular-step-shaped, so that the retainer ring can be connected and fixed with other parts of a motor. Bolts can penetrate the axial through holes in the outer edge of the retainer ring to conduct fixation and prevent the retainer ring from displacement.
Description
Technical field
The utility model relates to a kind of motor back-up ring.
Background technique
Existing motor is general by the insulation effect of back-up ring, and simple in structure, and great majority are a circular cylinder, function singleness.
In sum, for shortcomings and deficiencies of the prior art, need especially a kind of good insulation preformance and there is multi-functional motor back-up ring, to address the above problem.
Model utility content
The purpose of this utility model is to provide a kind of can solve the as above motor back-up ring of problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of motor back-up ring, it is characterized in that, back-up ring adopts epoxy resin bonded fiber to make, the inward flange of described back-up ring is provided with the ring-shaped step concentric with back-up ring, described back-up ring outward edge is circumferentially uniform is provided with some axial holes, and the inwall of described back-up ring is also provided with some circular grooves concentric with back-up ring.
In a kind of preferred embodiment of the present utility model, the external diameter of described back-up ring is 475mm, and internal diameter is 382mm, and the outward edge height of described back-up ring is 16mm, and inward flange height is 30mm.
In a kind of preferred embodiment of the present utility model, described axial hole is 12, is circumferentially uniformly arranged on described back-up ring outward edge.
In a kind of preferred embodiment of the present utility model, on described back-up ring, be also symmetrically arranged with a pair of radial location through hole.
Owing to having adopted technological scheme as above, the utility model adopts epoxy resin bonded fiber to make, there are good insulating property, mechanical strength is high, and the middle part of back-up ring is annular table scalariform, is conveniently connected and fixed with other part of motor, the outer peripheral axial hole of back-up ring can be for bolt through fixing, the displacement of anti-Sealing shield ring, the circular groove of back-up ring inwall can also be used in conjunction with the part with circular fold, further fixing back-up ring.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to a kind of motor back-up ring shown in Fig. 1 to Fig. 3, back-up ring 100 adopts epoxy resin bonded fiber to make, and has good insulating property, and mechanical strength is high, is applicable to the back-up ring that each part of motor connects.The inward flange of back-up ring 100 is provided with the ring-shaped step 120 concentric with back-up ring 100, and other part convenient and motor is connected and fixed.
Back-up ring 100 outward edges 110 are circumferentially uniform is provided with 12 axial holes 111, can be for bolt through fixing, and anti-Sealing shield ring 100 displacements.
The external diameter of back-up ring 100 is 475mm, and internal diameter is 382mm, and the outward edge 110 of back-up ring 100 is highly 16mm, and inward flange height is 30mm.
The inwall of back-up ring 100 is also provided with some circular grooves 121 concentric with back-up ring 100, and circular groove 121 can be used in conjunction with the part with circular fold, further fixing back-up ring 100.
On back-up ring 100, be also symmetrically arranged with a pair of radial location through hole 130, facilitate location and the reference of back-up ring 100.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
