Abstract
The utility model discloses a commutator of wholly plastic type, which comprises a commutating segment 1, a moulding material 2. The contour of the moulding material 2 is provided with a cross salient structure 4 which is mutual interval combining arrangement with the commutating segment 1. The utility model uses the cross salient structure of the contour of the moulding material instead of the traditional mica lamination, which makes the mutual groove width of the commutating segment well distributed and the residue in the groove can be easily cleared. Therefore, compared with the existing technic, the utility model has the advantages that the insulating property is improved and the error of the motor commutation frequency is reduced.
Description
(1) technical field
The utility model relates to a kind of motor commutator.
(2) background technology
Existing commutator comprises commutator segment, mica sheet, moulding compound, and commutator segment and mica sheet are spaced (claiming half plastotype commutator).There is error in calibration when groove milling, the mica slot groove width distribution of sizes inequality after causing processing, and leave a little crumb in the mica slot, be not easy to cleaning.Thereby the insulation property of commutator and the commutating frequency of motor have been influenced.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of commutator segment is evenly distributed each other, the full-plastic commutator of good insulation preformance and provide.
The purpose of this utility model realizes by following technical solution: a kind of full-plastic commutator, comprise commutator segment, moulding compound, and the profile of moulding compound has the cross bulge-structure, and described cross bulge-structure cooperates arrangement with the commutator segment space.
After adopting the utility model structure, owing to utilize the cross bulge-structure of moulding compound profile to replace traditional mica sheet, make the mutual groove width even size distribution of commutator segment, and residue is easy to cleaning in the groove.Therefore, the utility model compared with prior art, insulation property are improved, and have reduced the motor commutation frequency error, and carbon brush can be turned round steadily at commutator face, contact is good, has improved the motor serviceability, reduces spark, has prolonged motor useful life.
(4) description of drawings
Fig. 1 is the structural representation of the utility model full-plastic commutator.
Fig. 2 is the D-D cutaway view of Fig. 1.
Fig. 3 is the structural representation of the moulding compound among Fig. 2.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2 and Fig. 3 as can be known: the utility model full-plastic commutator is made of commutator segment 1, moulding compound 2, lining 3, wherein the profile of moulding compound 2 has cross bulge-structure 4, and described cross bulge-structure 4 cooperates arrangement with commutator segment 1 space.The utility model utilizes the cross bulge-structure of moulding compound profile to replace traditional mica sheet, utilize blade inserting technology to make the mutual groove width even size distribution of commutator segment, thereby reduced the motor commutation frequency error, carbon brush can be turned round steadily at commutator face, contact is good, improve the motor serviceability, reduced spark, prolonged motor useful life.And residue is easy to cleaning in the groove, has improved the insulation property of commutator.In addition, need not use mica sheet, can reduce processing technology, economical with materials reduces cost, and has improved production efficiency.
Claims (1)
1, a kind of full-plastic commutator comprises commutator segment (1), moulding compound (2), and it is characterized in that: the profile of moulding compound (2) has cross bulge-structure (4), and described cross bulge-structure (4) cooperates arrangement with commutator segment (1) space.
