Abstract
The utility model relates to a motor rolling reverser. The rolling friction is arranged between an electric brush and a reversing seed of the new motor rolling reverser, namely, the connecting position of the electric brush and the reversing seed is still relatively, so the motor rolling reverser has the advantages of little wearing and little electric spark and is especially suitable for motors with brushes to increase the service life and reliability. By the proof of the specific embodiment, the service life of the motor rolling reverser is more than 10000 hours, and the efficiency of the motors with brushes can be increased by more than 10 percents.
Description
Motor slip commutator in the past has following shortcoming: promptly because brush exists the very big sliding friction of relative linear velocity with commutation between the son, caused wear of brush soon, the sub-quick abrasion that commutates, had a strong impact on life-span, reliability and the economy of brush motor; All the time the electric spark that exists between brush and commutation when motor moves in addition causes the extraneoas loss of a large amount of electric energy, thereby greatly reduces the efficient of brush motor, and the range of application of brush motor is restricted.The utility model relates to a kind of motor rolling commutator, between the brush of this New-type electric machine commutator and commutation is rolling friction, be that brush is relative static with the binding site that commutates between the son, therefore these motor rolling commutator wearing and tearing are little, electric spark is also little, is particularly suitable for brush motor to improve its life-span, reliability, economy and efficient.Prove that through specific embodiment the life-span of this motor rolling commutator can make the efficient of brush motor improve more than 10% greater than 10000 hours.The utlity model has wide application prospect.
The technical solution of the utility model is:
Motor rolling commutator is made up of roller brushes and commutation, and roller brushes contacts with commutation at suitable pressures, does not almost have relative motion between roller brushes and commutation when motor rotates.Roller brushes is made up of graphite roller, carriage, spring, lead access terminal etc.Commutation can adopt various radially commutation of common brushed motor.
The utlity model has following advantage:
1) life-span is long.
2) electric spark is little.
3) efficient height.
4) can be used for various brush motors easily.
Further specify specific structural features of the present utility model below in conjunction with Figure of description and embodiment.
Brief Description Of Drawings:
Fig. 1, Fig. 2 are the overall installation diagrams of the utility model motor rolling commutator, and Fig. 1 is the roller brushes outer-installed type, and Fig. 2 is the roller brushes built in type.1 is the support leaf spring of roller brushes among Fig. 1 and Fig. 2, and it is fixed on the motor housing, and it plays the effect of supporting roller brushes; The 2nd, roller brushes, it passes to commutation to electric current; The 3rd, commutation, it links to each other with machine winding coil.
Fig. 3 is the assembling schematic diagram of the roller brushes of the utility model motor rolling commutator.4 is leads among Fig. 3; The 5th, carriage; The 6th, spring; The 7th, the graphite rolling wheel support; The 8th, the graphite roller.
Operation principle of the present utility model is:
As shown in Figure 1 to Figure 3, the electric current of power supply passes to graphite roller 8 by lead 4 and graphite rolling wheel support 7, graphite roller 8 contacts with commutation 3 and electric current is passed to an end of motor coil, and the electric current that flows out coil turns back to power supply by another relative roller brushes.Drive 8 rotations of graphite roller with commutation 3 of rotor rotation synchronously by friction, almost do not have relative motion between them.Relative motion occurs between graphite roller 8 and the graphite rolling wheel support 7, and the linear velocity of this relative motion is much smaller than the linear velocity between general motor slip commutator brush and commutation.
