Description
Technical field
The utility model is related to a kind of commutator accessory, more particularly to a kind of commutator strengthening ring.
Background technology
Commutator is main parts size in brush motor, circumferential by force intensity in order to strengthen it, it will usually in its periphery
Reinforcing ring is arranged on face.Traditional reinforcing ring is shaped by resin and glass fibre.However, in traditional processing mode, glass
Glass fiber is perpendicular and the longitudinally staggered preliminary configuration into motor reinforcing ring, and resin is then coated thereon, and real by baking oven
Apply baking molding.There is larger hollow out after glass fibre is perpendicular and longitudinally staggered successively thereon, the stress of the hollow part is strong
Degree is weaker, easily ruptures in use.And traditional reinforcing ring, after long-time use, its outer wall is vulnerable to
Abrasion.
The content of the invention
In view of the deficienciess of the prior art, the utility model is there is provided a kind of big, wear-resisting, simple in construction by force intensity
Commutator strengthening ring.
To achieve the above object, the utility model provides following technical scheme：A kind of commutator strengthening ring, its feature exists
In：If including the body that dried layer is mutually bonded, described body respectively by glass fibre bar knitting forming, each body
Outer surface is coated with resin bonded laminate, and the cross section of outermost layer body is tapered, and the outer peripheral face of outermost layer body is provided with some
Shirt rim；Described each body is respectively by netted glass fibre bar knitting forming.
Using above-mentioned technical proposal, by being coated with resin bonded laminate in vitro at this, not only make to have preferably between each body
Adhesivity, connect more firm during curing molding, the cross section of outermost layer body set tapered, so setting
Also ensure it by force intensity while outermost layer body extended area can be reduced；The setting of shirt rim and each body are respectively by net
The glass fibre bar knitting forming of shape is then to be further reinforcement body by force intensity.
The utility model is further arranged to：Body has at least two layers, wherein positioned at the glass fibre bar of internal layer body
Netted angle of weave be less than outermost layer body glass fibre bar netted angle of weave.
Using above-mentioned technical proposal, so setting can have the glass fibre bar between innermost layer body and outermost layer body
Play the role of mutually to coat, reduce electric leakage, promote being improved by force intensity for body.
The utility model is further set to：Some slots, described skirt are offered on the outer peripheral face of outermost layer body
While being plugged in the slot.
Using above-mentioned technical proposal, so set easy to assembly.
The utility model is further set to：Be installed with locating ring on the inwall of innermost layer body, the locating ring it is interior
Wall is provided between some positioning convex, and locating ring and innermost layer body to be connected by dovetail neck and dovetail fixture block.
Using above-mentioned technical proposal, so setting can make the connection between the reinforcing ring and commutator more compact, make
Strengthened during commutator by force intensity.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is this Fig. 1 I portions enlarged diagram.
Embodiment
A kind of commutator strengthening ring as shown in Figure 1 and Figure 2, if including the body 1 that dried layer is mutually bonded, body 1 is distinguished
By glass fibre bar knitting forming, the outer surface of each body 1 is coated with resin bonded laminate 2, and the cross section of outermost layer body 1 is in cone
Shape, the outer peripheral face of outermost layer body 1 is provided with some shirt rims 3；Each body 1 is respectively by netted glass fibre bar knitting forming.
In such scheme, by being coated with resin bonded laminate in vitro at this, not only make that there is preferable adhesivity between each body 1, solid
Connect more firm during chemical conversion type, the cross section of outermost layer body 1 is set tapered, outermost layer can be reduced by so setting
Also it can be ensured by force intensity while 1 extended area of body；The setting of shirt rim 3 and each body 1 are respectively by netted glass
Ribbon knitting forming is then to be further reinforcement body 1 by force intensity.
In the utility model embodiment, body 1 has at least two layers, in the utility model embodiment exemplified by two layers,
Depending on its certain quantity can be according to design.Netted angle of weave wherein positioned at the glass fibre bar of internal layer body 1 is less than outermost
The netted angle of weave of the layer glass fibre bar of body 1.The glass between innermost layer body 1 and outermost layer body 1 can be made by so setting
Glass ribbon has the effect mutually coated, reduces electric leakage, promotes being improved by force intensity for reinforcing ring.
In order that processing and assembling more convenient.Some slots 11, shirt rim 3 are offered on the outer peripheral face of outermost layer body 1
It is plugged in the slot 11.In use, outside part directly will not occur to scrape or rub with reinforcing ring, so that plus
The strong wearability of reinforcing ring, while extending the service life of reinforcing ring.
In order that the connection between reinforcing ring and commutator is more compact, positioning is installed with the inwall of innermost layer body 1
Ring 4, the inwall of the locating ring 4 is provided with some positioning convex 41, and passes through dovetail card between locating ring 4 and innermost layer body 1
Groove 12 and dovetail fixture block 42 are connected.
