Description

Motor sheath

Technical Field

The utility model relates to the technical field of motors, specifically a motor sheath.

Background

The motor carbon brush is a generic term for a carbon brush of a motor and a carbon brush of a generator. The carbon brush of the motor is similar to a rubber strip for wiping a pencil, a lead is led out from the top of the carbon brush, and the size of the carbon brush is small. The motor is used for changing the current direction to be divided into a direct current motor and an alternating current motor, wherein the direct current motor is used for changing the conductive coil of the rotor, so that the magnetic pole of the rotor is changed, and the motion of the motor is further changed. The carbon brush is used on a commutator or a slip ring of a motor as a sliding contact body for leading out and leading in current, has good electric conduction, heat conduction and lubrication performance, and has certain mechanical strength and the instinct of commutation spark. Almost all brush motors use carbon brushes, which are important components of brush motors. The method is widely applicable to various alternating current and direct current generators, synchronous motors, battery direct current motors, crane motor collecting rings, various electric welding machines and the like. Has better reversing performance and long service life.

The existing carbon brush of the motor is exposed outside, the protection of the carbon brush is lacked, foreign matters easily enter the carbon brush, and the reliability of the motor is reduced. Therefore, the utility model provides a motor sheath to solve the problem that proposes among the above-mentioned background art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a motor sheath to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a motor sheath, includes the motor, the carbon brush department cover of motor is equipped with the sheath, the sheath is located plane department that is parallel to each other and is equipped with the movable block, has seted up the trompil between movable block and the sheath, the movable block is located the inside terminal surface of sheath and is equipped with the fixture block, is equipped with the arch on the fixture block.

As a further aspect of the present invention, the sheath is circular, and the outer edge symmetry of the sheath is provided with planes parallel to each other.

As the utility model discloses further scheme again, the inside symmetry of sheath is equipped with the locating pin, and the top of locating pin is the toper.

As the utility model discloses further scheme again, the sheath corresponds the motor shaft and has seted up the mounting hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the sheath is sleeved at the carbon brush of the motor, the sheath is fixed with the motor by the aid of the protrusions of the fixture blocks, foreign matters are prevented from entering the carbon brush by the aid of the sheath, and reliability of products can be improved.
