Abstract

The utility model provides a sealing device of a motor bearing pedestal, comprising a shaft and an end housing, wherein, the end housing is used for supporting the tilting fillet of the bearing pedestal and the end face of the shaft and is provided with a seal groove. The sealing device is characterized in that a ring groove is arranged on the end housing; and an oil deflector ring on the shaft is arranged in the ring groove. The sealing device fundamentally solves the technical problem of the oil leak of the tilting fillet of the bearing pedestal, eliminates the potential safety hazard of the device caused by the flashover of the slip ring of the motor, reduces device failure rate, reduces fault time, improves the operating rate of the device, creates good condition for manufacturing, simultaneously precludes pollution caused by device running, emitting, dripping and leaking, and reduces workers labour intensity. The sealing device has simple structure, is easily machined, has strong applicability and can be applied to the sealing of various bearing pedestal.

Description

A kind of motor shaft bearing seal arrangement

Technical field

The utility model relates to a kind of seal arrangement, and especially a kind of motor shaft bearing seal arrangement belongs to the shaft sealing technical field.

Background technique

When motor moved, its sliding bearing was worked under sliding friction, because motor shaft is to support by oil-film floating, bear bigger radial force, so flow out vertically after lubricant oil is squeezed, bad when the bearing support end face seal, lubricant oil will produce leakage vertically.The lubricant oil that leaks from the removable metal seat can screw out and the generation seepage along the motor shaft surface, the lubricating oil splash of seepage is to motor collecting ring, can cause block brush and collector ring bad connection, and make between collector ring and block brush the arcing phenomenon takes place, thereby make the collector ring ablated surface, damage, finally cause the electrical machine insulation performance to reduce, very easily cause between the collector ring or the collector ring shorted to earth, cause the tripping grinder accident, even cause motor three phase circuit injustice, and cause the local excess current of motor windings, overheated, rotor winding and headgear sealing-off, rotor is damaged, stopped production by forced-stopping machine, its result who brings is: one, influence ordinary production; Two, increase amount of maintenance and maintenance cost; Three, strengthen staff's labor intensity; Four, cause the loss of a large amount of lubricant oil because of seepage, and increase cost of production; Five, because of a large amount of losses of lubricant oil, the environment of water and periphery has been caused serious pollution, simultaneously, water-treating equipment have also been caused infringement, the utmost point is unfavorable for the energy-saving and emission-reduction policy implemented.Therefore, be necessary prior art is improved.

Summary of the invention

For overcoming the oil seepage problem that prior art exists, the utility model provides a kind of motor shaft bearing seal arrangement, to prevent the seepage of lubricant oil.

The utility model is finished by following technical proposal: a kind of motor shaft bearing seal arrangement, comprise axle, the end cap that is used for the band seal groove of the bearing support watt seat of back shaft and end face thereof, it is characterized in that end cap is provided with annular groove, flinger ring on the axle places in this annular groove, screws out along the axle surface with the lubricant oil that prevents seepage.

Described annular groove is arranged at the one or both sides of seal groove on the end cap, so that the flinger ring on the axle places in the annular groove, overflows vertically with the lubricant oil of leakage proof.

Described annular groove is arranged on the end cap between two seal grooves, so that the flinger ring on the axle places in the annular groove, overflows vertically with the lubricant oil of leakage proof.

Described flinger ring is anchored on the axial plane, and the quantity of flinger ring is corresponding with the annular groove quantity on the end cap, screws out along the axle surface with the lubricant oil of leakage proof.

The utility model compared with prior art has following advantage and effect: adopt such scheme; fundamentally solve the technical barrier of motor bearings watt seat leakage of oil; eliminate the device security hidden danger that the motor sliding ring arcing causes; reduce equipment failure rate; reduce fault power time; the operating rate of raising equipment; for advantageous conditions has been created in production; the equipment of stopping simultaneously is because of the run, drip, leak pollution on the environment; alleviate working strength of workers, this sealing device structure is simple, easily processing; applicability is strong, can be used for the sealing of various bearing supports.
