Abstract
The utility model relates to an oil leakage-proof device for the blower motor, which replaces the structure of connecting one end of a shaft (2) of a blower motor (1) with a metal bearing (3) in the prior technology with the structure of connecting one end of the shaft of the blower motor with a lateral side of the shell (4) and placing one end of the shaft of the blower motor in the main assembling position (6) of an end cover (5) for connecting with the metal bearing (3). The shaft (2) which is assembled with the metal bearing (3) is structured in ring-shaped inside in order to inserting an orring (8) in the groove for mutual connection. The utility model which relates to the special oil leakage-proof device for the blower motor (1) could effectively prevent the oil flowing to a commutator (9).
Description
Technical field
The utility model is about preventing that the leakage of oil of forced draft fan motor from flowing into the technology of commutator (commutator).Be one specifically and metal bearing be contained in motor housing, to reduce the leakage of oil that takes place when motor rotates about for preventing that the leakage of oil of forced draft fan motor from flowing into commutator; The top formation groove of axle is gone into commutator to cut off machine oil along axial flow; And orring combined with above-mentioned groove, thereby more effective preventing spills the device that the machine oil that comes flows into commutator from the forced draft fan motor.
Background technology
General forced draft fan motor (shown in figure-1,2), be installed in casing (12) inside of motor (11) because of metal bearing (10), so being deposited on the machine oil of metal bearing (10) when having motor (11) rotating drive can outwards flow out, and rise or splash inflow commutator (14) along axle (13), the dust of brush etc. is adsorbed in above the commutator (14), thus the disadvantage of damage motor (11).
The utility model content
As mentioned above, adopt the forced draft fan motor of conventional art to exist machine oil to flow into the disadvantage of commutator.In order to prevent this difficult problem, the utility model provides the forced draft fan motor isolated plant that prevents that machine oil from flowing into.For preventing that the leakage of oil of forced draft fan motor from flowing into commutator, metal bearing is contained in motor housing, to reduce the leakage of oil that takes place when motor rotates; The top formation groove of axle is gone into commutator to cut off machine oil along axial flow; And orring combined with above-mentioned groove, thereby more effectively prevent that spilling the machine oil that comes from the forced draft fan motor flows in the commutator.Provide this forced draft fan motor special engine oil inflow device, to satisfy technical task of the present utility model.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the side that the metal bearing (3) that an end of axle (2) that conventional art adopted and forced draft fan motor (1) is combined is changed into casing (4) combines, and be located on the main binding site (6) of end lid (5), combine with metal bearing (3).The inboard of the axle (2) that combines with above-mentioned metal bearing (3) forms annular, so that orring (8) is inserted above-mentioned groove (7), and combines with it.
Form said structure according to the utility model, will prevent that machine oil from flowing in the commutator of forced draft fan motor (1), thereby effectively prevent damage motor.
At first, the metal bearing (3) that the utility model will combine with axle (2) originally changes into and a side of casing (4) combines, and be located on the main binding site (6) of end lid (5), thereby disposable when having stopped motor (1) rotation machine oil flow into the phenomenon of commutator.And above-mentioned axle (2) is gone up formation groove (7), combines with orring (8), has prevented that thoroughly machine oil from flowing into the phenomenon of commutator (9) along axle (2).
Effect of the present utility model is as follows:
As mentioned above, forced draft fan motor provided by the utility model (1) special use prevents the machine oil inflow device, plays to prevent that the machine oil that sinks to metal bearing (3) from flowing in the commutator (9).In order to reach this purpose, the utility model is installed metal bearing (3) towards the outside of motor (1) casing (4), and the machine oil that takes place in the time of can reducing motor (1) rotation to greatest extent flows in the commutator (9).Axle (2) is gone up and is formed groove (7), and combines with orring (8), cuts off machine oil and drops down along axle (2), thereby prevent that effectively machine oil from flowing in the commutator (9).

Embodiment
Fig. 3 adopts the profile of the forced draft fan motor that prevents the machine oil inflow device that the utility model provides for diagram.With reference to above-mentioned profile, the utility model is described in detail as follows:
The side that the utility model changes into the metal bearing (3) that conventional art adopted and an end of the axle (2) of forced draft fan motor (1) combines with casing (4) combines, and be located on the main binding site (6) of end lid (5), combine with metal bearing (3).The inboard of the axle (2) that combines with above-mentioned metal bearing (3) forms annular, so that orring (8) is inserted above-mentioned groove (7), and combines with it.
Form said structure according to the utility model, will prevent that machine oil from flowing in the commutator of forced draft fan motor (1), thereby effectively prevent damage motor.
At first, the metal bearing (3) that the utility model will combine with axle (2) originally changes into and a side of casing (4) combines, and be located on the main binding site (6) of end lid (5), thereby disposable when having stopped motor (1) rotation machine oil flow into the phenomenon of commutator.And above-mentioned axle (2) is gone up formation groove (7), combines with orring (8), has prevented that thoroughly machine oil from flowing into the phenomenon of commutator (9) along axle (2).
Claims (1)
1. locking apparatus is prevented in the leakage of oil of forced draft fan motor, it is characterized in that: the side that the metal bearing (3) that conventional art adopted and an end of the axle (2) of forced draft fan motor (1) combines is changed into casing (4) combines, and be located on the main binding site (6) of end lid (5), combine with metal bearing (3); The inboard of the axle (2) that combines with above-mentioned metal bearing (3) forms annular, so that orring (8) is inserted above-mentioned groove (7), and combines with it.
