Abstract
The utility model discloses a plane commutator, which comprises commutating sheets and bakelite powder, wherein, the commutating sheets is perpendicular to the shaft line of the commutator. The utility model is characterized in that a mica sheet is arranged between the commutating sheets; the commutating sheets and the mica sheet are separately punched and assembled for forming. The commutating sheets of the utility model changes thin plate punching into separate punching and assembly for forming. The thickness of the working surface of each commutating sheet can be optionally increased. Compared with the prior art, the utility model has the advantages of large current bearing and long service life, and is especially suitable for the motors with the requirements of large current and long service life.
Description
The utility model relates to a kind of flat commutator.
Existing flat commutator constitutes (claiming the full-plastic flat commutator) by commutator segment and phenolic moulding powder, and the axis of commutator segment body and this commutator is perpendicular.Commutator segments all in this commutator are only formed by a sheet stamping, its working face thickness can not arbitrarily increase, therefore, the operating current that this commutator bears can not be very big, has been subjected to considerable restraint as automobile, motor generator or startup with the large-current electric machine.And working life is shorter, is generally about hundreds of hours to 2,000 hours.
The purpose of this utility model is to overcome above-mentioned deficiency, and the flat commutator that provides a kind of commutator segment can arbitrarily increase for modular, its working face thickness separately.
The purpose of this utility model realizes by following technical solution: a kind of flat commutator, comprise commutator segment, phenolic moulding powder, the axis of commutator segment and this commutator is perpendicular, is provided with mica sheet between the described commutator segment, and commutator segment and mica sheet are independent punching out assembled formation.
After adopting the utility model structure, because it is independent punching out assembled formation that commutator segment changes a sheet stamping, being provided with insulation between the commutator segment and use mica sheet, thereby the working face thickness of commutator segment can arbitrarily increase, compared with prior art have bear electric current greatly, the advantage of long working life.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model flat commutator.
Fig. 2 is the B-B cut-away view of Fig. 1.
With reference to Fig. 1, Fig. 2 as can be known: the utility model flat commutator constitutes (claiming half plastotype flat commutator) by commutator segment 1, phenolic moulding powder 2, mica sheet 3, the axis of commutator segment and this commutator (O axle) is perpendicular, mica sheet is located between the commutator segment makes insulation usefulness, and commutator segment and mica sheet are independent punching out assembled formation.In order to make phenolic moulding powder and commutator segment contact strength reliable, product with compact structure, can with the contacted commutator segment of phenolic moulding powder on be provided with groove, form anti-dovetail structure.Because it is independent punching out assembled formation that commutator segment changes a sheet stamping, be provided with the insulation mica sheet between the commutator segment, the working face thickness L of commutator segment can arbitrarily increase, and commutator segment has anti-dovetail structure, the electric current of bearing is big so the utility model compared with prior art has, long working life, compact conformation, the reliable advantage of intensity, is specially adapted to the motor that big electric current, long-life require.In addition, the crotch portion size size of commutator segment, then according to the motor rated current and select the diameter of wire thickness for use and decide, hook exchanges than being easier to grooved; The thickness of mica sheet can require to determine, widen the scope of application of commutator significantly according to commutator-segment insulation.
