TRACTION MOTOR FOR mine electric locomotives

摘要

The invention relates to electrical engineering. Traction-type DC motor 812 is in the normal mine one execution and is intended for contact electric clutch weight 14 tons.; The motor comprises a fixed inductor, comprising a housing having a circular shape, with a flange fastening of the engine to the gearbox, on the inner surface of the housing are four main and four poles, the coils of the poles are made of copper bars, and a rotating armature comprising a shaft on which are arranged core with a winding, collector, fan bearings and maslozaschity rear bearing assembly housing is closed at its ends bearing shields, which are placed in bearings on the front endshield yc anovleno four brush holder with springs that urge brush to the commutator, the housing is made hatch capped with seal for the maintenance of the brush apparatus and the collector, and it is set terminal box, with holes for supplying to the engine external conductors, wherein as the interturn insulation Reels used insulation type "nomex", a spring roll formed, providing a constant pressure on the brush regardless of its height, as the brush - Discontinuous consisting of two parts having common laths - amor iziruyuschuyu rubber and rigid of profile fiberglass maslozaschity assembly includes a cover, in which there are lip reinforced seal covering the ball bearing, the cover is attached a protective disc, and a locking sleeve attached movable cover, motor mounting flange to the gearbox is welded to the engine casing, wherein performed four sewer manhole. The technical result - increasing the reliability.
