Abstract
The utility model discloses a sealing device for the lower extreme of a vertical shaker motor which comprises a rotor; the rotor is sleeved with the inner ring of an axle; the outer ring of the axle is arranged in an end close; the lower end of the rotor shaft is provided with a groove; a boss that inosculates the groove of the rotor is arranged on an end close. A specialized oil chamber for storing lubricant is arranged in the end close of the motor, with the effect of centrifugal, the lubricant can not leak out from the clearance between the boss and the groove. Compared with the prior art, the utility model has the advantages of simple structure, good effect of sealing, thus greatly minishing the motor volume and lowering manufacturing cost and hidden trouble for safety.
Description
Technical field
The utility model is used for the dynamo-electric machine of a kind of vertical vibrating lower end hermetically-sealed construction that the dynamo-electric machine of vertical vibrating prevents the bearing leakage of oil, belongs to technical field of motors.
Background technology
Because the dynamo-electric machine work under bad environment of vertical vibrating, the work period is long, and load is big.In original sealing structure,, the serious oil impregnate of a large amount of motors is often arranged at work owing on structural design, there is defective.Cause the spot corrosion of motor and bearing, the reputation of influence production and motor producer.The sealing means complex structure of the dynamo-electric machine of some vertical vibratings is more arranged, and processing capacity is big, and the motor volume of making is huge, weight increases, and has improved the manufacturing cost of motor, and the effect of sealing is bad.The equipment of particularly vertical bobbing machine motor and so on, motor carry out work for a long time under the situation of high-frequency vibration, security incident takes place because of leakage of oil easilier.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, good sealing effect is provided, can reduces the dynamo-electric machine of the vertical vibrating lower end hermetically-sealed construction of motor volume, improve the fail safe of motor and reduce production costs.
The utility model is to constitute like this: it comprises rotor (1), be with the inner ring of bearing (2) on the rotor (1), bearing (2) outer ring is installed in the end cap (3), is provided with groove (4) in rotor (1) axle lower end, is provided with on end cap (3) and the identical boss (6) of the groove (4) of rotor (1).In motor operation course, can effectively prevent the leakage of oil of motor bearings chamber, thereby prolong the useful life of motor widely, solved a long-term pendent difficult problem.
The dynamo-electric machine of above-mentioned vertical vibrating lower end hermetically-sealed construction is provided with ring-type oil sealing (7) between groove (4) and boss (6).
Be provided with an accumulator that stores lubricating oil in the end cap of the utility model motor specially, on end cap, produce in the groove that boss snaps in rotor bottom, under motor rotation Qing Indistinct, rotor high-speed rotates, under action of centrifugal force, lubricating oil can not spill by the gap between groove and the boss, good sealing effect.Therefore compare with prior art, the utlity model has simple in structure, advantage of good sealing effect.Motor volume be can reduce greatly, production cost and potential safety hazard reduced simultaneously.The original dynamo-electric machine of the vertical vibrating of a 4kw, about 250 kilograms, if the vertical vibrating machine of a 7kw, weight can reach more than 500 kilograms weight usually.And the vertical vibrating motor of employing the utility model structure, 4kw has only 150 kilograms, and 7kw has only 240 kilograms, has alleviated the volume of motor, has saved production cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the rotor (1) of making motor, produce the groove (4) of annular in rotor (1) bottom, go up an accumulator of making (5) at the end cap (3) of bearing (2) below and collect lubricating oil, produce boss (6) in the position that end cap (3) bottom is connected with bearing, go up installation bearing inner race (2) at rotor (1), bearing (2) outer ring is installed in the end cap (3), boss (6) is snapped in the groove (4), better for sealing effectiveness, ring-type oil sealing (7) can also be installed between the gap of boss (6) and groove (4).
Claims (2)
1, the dynamo-electric machine of a kind of vertical vibrating lower end hermetically-sealed construction, it comprises rotor (1), be with the inner ring of bearing (2) on the rotor (1), bearing (2) outer ring is installed in the end cap (3), it is characterized in that: be provided with groove (4) in rotor (1) axle lower end, on end cap (3), be provided with and the identical boss (6) of the groove (4) of rotor (1).
2, the dynamo-electric machine of vertical vibrating according to claim 1 lower end hermetically-sealed construction is characterized in that: be provided with ring-type oil sealing (7) between groove (4) and boss (6).
