Description
Technical field
Commutator field is the utility model is related to, there is the commutator of the insulation scraps of paper more particularly to a kind of iron hoop of reinforcing.
Background technology
Commutator is part essential in motor, is required to install reinforcing ring in present commutator to improve commutation
The bulk strength of device, reinforcing ring are made of using metal material mostly, and reinforcing ring is probably and copper sheet in the structure of commutator
Directly contact, produce the phenomenon of short circuit, and the corrosion-and high-temp-resistant of reinforcing ring in itself can be bad, in situation about running at high speed
Under, for rotor because offset is small between piece caused by running at high speed, out of roundness deflection is small, influences performance.
The content of the invention
Technical problem to be solved in the utility model, which is to provide a kind of iron hoop of reinforcing, has the commutator of the insulation scraps of paper, knot
Structure is simple, by reinforcing ring setting structure particularly insulate very much the scraps of paper, reinforcing ring can not be in contact with copper sheet, can also have
Effect protection reinforcing ring, especially suitable for high-power start motor and electric tool.
Technical scheme is used by the utility model solves its technical problem：There is provided a kind of iron hoop of reinforcing has insulating paper
The commutator of piece, including mica and copper sheet, described mica and copper sheet are evenly distributed annular in shape every ground around circumference, described
Mica and the inner side of copper sheet be filled with plastic body, the upper and lower ends groove of the inner side dovetail part of described copper sheet, which is embedded in, to be disposed with
Reinforcing ring, the insulation scraps of paper is disposed with the outside of the reinforcing ring, the described insulation scraps of paper include annular substrate, described annular substrate
Outer edge be disposed with several inner side insulating trips and outside insulating trip respectively around even circumferential, described annular substrate,
The bottom surface with reinforcing ring, madial wall and lateral wall are close to respectively for inner side insulating trip and outside insulating trip.
Preferably, the described insulation scraps of paper are made of imines membrane material.
Further, the length of described outside insulating trip is more than the length of inner side insulating trip.
Beneficial effect：The utility model is related to a kind of iron hoop of reinforcing has the commutator of the insulation scraps of paper, and structure improves small, effect
Fruit is obvious, and iron hoop structure has high temperature resistant, and integral heat sink is good, can suppress the effect expanded with heat and contract with cold；The scraps of paper insulate using sub-
Amine membrane material, have high temperature resistant, good insulation preformance, intensity high.The insulation scraps of paper can be purchased according to iron hoop specification, be then washes out institute
The size needed, the scraps of paper, which need the piece number required for going out, to be designed according to commutator segment dovetail, compared with prior art, insulation
The scraps of paper add iron hoop to improve rotor because offset is small between piece caused by running at high speed, and out of roundness deflection is small, good insulation preformance,
Product will not produce short circuit phenomenon, and improve the integral rigidity of product, so as to reduce product rejection rate, improve the use of product
Life-span and performance, especially suitable for high-power start motor and electric tool.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As shown in Figure 1-2, embodiment of the present utility model, which is related to a kind of iron hoop of reinforcing, has the commutator of the insulation scraps of paper,
Including mica and copper sheet 3, described mica and copper sheet 3 are evenly distributed annular in shape every ground around circumference, described mica and
The inner side of copper sheet 3 is filled with plastic body 4, and the upper and lower ends groove of the inner side dovetail part of described copper sheet 3, which is embedded in, is disposed with reinforcing
Ring 1, the outside of the reinforcing ring 1 are disposed with the insulation scraps of paper 2, and the described insulation scraps of paper 2 include annular substrate 6, described annular base
The outer edge of piece 6 is disposed with several inner side insulating trips 5 and outside insulating trip 7, described annular respectively around even circumferential
The bottom surface with reinforcing ring 1, madial wall and lateral wall are close to respectively for substrate 6, inner side insulating trip 5 and outside insulating trip 7.
The described insulation scraps of paper 2 are made of imines membrane material.
The length of described outside insulating trip 7 is more than the length of inner side insulating trip 5.
The utility model structure improves small, positive effect, and iron hoop structure has high temperature resistant, and integral heat sink is good, can press down
Make the effect expanded with heat and contract with cold；The insulation scraps of paper use imines membrane material, have high temperature resistant, good insulation preformance, intensity high.Insulate the scraps of paper
It can be purchased according to iron hoop specification, be then washes out required size, it is according to commutation that the scraps of paper, which need the piece number required for going out,
Piece dovetail designs, and compared with prior art, the insulation scraps of paper add iron hoop to improve rotor because between piece caused by running at high speed
Offset is small, and out of roundness deflection is small, good insulation preformance, and product will not produce short circuit phenomenon, and improve the integral rigidity of product,
So as to reduce product rejection rate, improve the service life and performance of product, especially suitable for high-power start motor and
Electric tool.
