Abstract
The utility model discloses a housing molded commutator comprising commutator segments and a bakelite body, wherein the commutator segments are sequentially arranged at intervals to form a commutator segment assembly having an outer cylindrical working face and an inner cavity, the bakelite body is arranged in the inner cavity and fixedly connected to the commutator segment assembly, the commutator segment assembly is shaped through a moulded housing, and the moulded housing comprises a circular body and recesses and protrusions arranged on the inner wall of the circular body at intervals. The recesses match in shape with the commutator segments, and the protrusions match in shape with the gaps. The commutator segments are stuck in the recesses, and protrusions form bakelite powder grooves. The width and calibration of an integrally formed lower notch are uniform, thereby effectively reducing the noise during running of a motor. The bakelite powder groove is smooth, and carbon powder falling into the groove may not be attached to the groove and can be easily discharged. The insulation breakdown between sheet due to accumulation of carbon powder of a wearing carbon brush and the commutator in the lower notch can be reduced.
Description
Technical field
The utility model relates to a kind of commutator, particularly relates to a kind of commutator of housing moulding.
Background technology
The commutator of conventional washing machine uses mica sheet to carry out lamination insulation, by cutting under the formation of the mica sheet between adjacent two commutator segments of Milling Process, because of flute length long, well width is narrow, the equal indicative of the groove that processes is poor, mica is difficult for removing totally fully in the groove, causes that groove width is narrow inconsistent, causes motor noise big, problems such as the life-span is low, poor with roughness in the time slot, commutator when high speed rotating and carbon brush wear and tear mutually, not thorough if the carbon dust after the carbon brush wearing and tearing is discharged, stick easily in mica slot, the carbon dust of absorption can not in time be discharged in the mica slot, causes that easily lamination insulation punctures, and produces phenomenons such as the row of flying.
The utility model content
For addressing the above problem, the utility model provides a kind of commutator that forms the housing moulding of phenolic moulding powder groove.
The technical solution of the utility model is as follows: a kind of commutator of housing moulding, comprise commutator segment and bakelite main body, and described commutator segment gap arrangement successively forms the commutator segment assembly; Described commutator segment assembly comprises cylindrical working face and inner chamber; Described bakelite main body is arranged in the described inner chamber and fixedly connected described commutator segment assembly, and described commutator segment assembly is by the moulding casing forming, and described one-tenth shell comprises annulus main body and the depressed part and the jut that are spaced in described annulus main body inner wall; Described depressed part and described commutator segment shape are complementary; Described jut and described gap shape are complementary; Described commutator segment is arranged in the described depressed part.
Preferably, described one-tenth shell also comprises annular supporting part, and the external diameter of described annular supporting part and the external diameter of described circumferential body are complementary and are connected in an end of described circumferential body.
Preferably, described commutator segment comprises body and the hook portion that is connected described body one end, the fixedly connected described bakelite main body of described body.
Preferably, described body comprises active section and canned paragraph, and described active section is exposed to outside the described bakelite main body; Described canned paragraph stretches in the described bakelite main body.
Preferably, described depressed part and described active section shape are complementary.
Preferably, described one-tenth shell is a plastic sheath.
Adopt the beneficial effect of above technical scheme: by depressed part and lug boss being set at interval at the inwall that becomes shell, and the body of commutator segment is inserted in the depressed part, then the phenolic moulding powder injection moulding is formed the bakelite main body between canned paragraph and lining, lug boss forms cutting under the phenolic moulding powder, the following cutting length unanimity of formation, the well width unanimity, the groove equal indicative distributes, and smooth no foreign matter in the groove effectively reduces running noise of motor, commutation spark is more well-balanced, prolongs electrical machinery life simultaneously; Simultaneously because of smooth in the groove, carbon dust falls into and can not stick in the groove in the groove, also in time discharges easily, has reduced because of carbon brush and commutator wear carbon dust to be deposited in down the lamination insulation puncture that causes in the cutting.
