Abstract
The utility model discloses an automobile motor commutator with integral cold forging, unique-step molding and whole plastic groove shape, comprising a commutating segment 1 and a bakelite 2, wherein the commutating segment 1 is parallel with the axis of the commutator, a foot 3 of the commutating segment 1 has a structure with a shape like a Chinese character ''tu'' (means soil) along the centerline. The automobile motor commutator designed according to the topic of the utility model is particularly applicable to high speed motor, can make contact strength of the commutating segment and the bakelite reliable, and compared to prior art, the commutator eliminates the phenomenon of jumping and flying plates, elevates the quality of the commutator, and prolongs the service life.
Description
Technical field
The utility model relates to a kind of electric motor of automobile commutator, particularly be the improvement invention of the overall plastic tank commutator of kind.
Background technology
The foot of the commutator segment of existing overall plastic tank commutator is commonly swallowtail-shaped structure, thereby the contact area of its commutator segment and phenolic moulding powder is just less, and promptly the adhesive force between commutator segment and the phenolic moulding powder is less.Film dancing, film flying phenomenon take place in this commutator easily in motor runs up process, and the grade of spark that causes motor to produce increases, even burns motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, can increase commutator segment and phenolic moulding powder contact area safe and reliable overall plastic tank commutator when motor runs up and provide a kind of.
The utility model is realized by following technical solution: integral cold forging one-shot forming electric motor of automobile commutator, include commutator segment, phenolic moulding powder, and the foot that it is characterized in that described commutator segment has along foot's center line and is native font structure.Described commutator segment parallels with the axis of this commutator, adopt the utility model structure, with the one-shot forming of copper pipe integral cold forging, and then be pressed into phenolic moulding powder, because what commutator segment foot had is native font structure along foot's center line, thereby increased the contact area of commutator segment and phenolic moulding powder, made that contact strength is reliable between the two, adhesive force is improved.Therefore, the utility model has compared with prior art been eliminated film dancing, the film flying phenomenon of commutator, has prolonged the useful life of commutator.
Description of drawings
Fig. 1 is the structural representation of the overall plastic tank commutator of the utility model;
Fig. 2 is the B-B cut-away view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described each relevant details, with reference to Fig. 1, Fig. 2, the utility model is overall plastic tank commutator, comprise commutator segment 1 phenolic moulding powder 2, so-called overall plastic being meant only has phenolic moulding powder between commutator segment and the commutator segment and do not have being called of mica sheet overall plastic, described commutator segment 1 parallels with the axis (O axle) of this commutator, and the foot 3 of described commutator segment 1 has along foot's center line and is native font structure.The utility model forms commutator ring by copper pipe through cold forging extruding, and this commutator ring is made up of the commutator segment of stipulating the sheet number, and each sheet connects into ring by boss, and every foot has along foot's center line and is native font structure.And then be pressed into phenolic moulding powder and form commutator, this commutator compared with prior art, owing to increased the contact area of commutator segment and phenolic moulding powder, film dancing, the film flying phenomenon of commutator have been eliminated effectively, improved the total quality of commutator, prolonged the useful life of commutator, in pot motor, used especially, will produce positive result of use according to the overall plastic tank commutator of the utility model design motif made.
Claims (2)
1, a kind of integral cold forging one-shot forming electric motor of automobile commutator, comprise commutator segment (1), phenolic moulding powder (2), it is characterized in that described phenolic moulding powder is pressed between each adjacent commutator segment, the foot (3) of described commutator segment (1) has along foot's center line and is native font structure.
2, a kind of integral cold forging one-shot forming electric motor of automobile commutator as claimed in claim 1 is characterized in that commutator segment (1) parallels with the axis of this commutator.
