Description
Technical field
The utility model relates to the sliding bearing technical field being provided to heavy-duty motor, particularly relates to a kind of self-lubricating plain bearing device for modifying for having on the threephase asynchronous machine being equipped with 9S sliding bearing.
Background technique
When threephase asynchronous machine operates, because the reasons in structure of motor internal wind path can produce negative pressure, cause part self-lubricating plain bearing (9S bearing) leakage of oil, affect the working life of threephase asynchronous machine, thus make it lose market competitive power.For solving above-mentioned prior art Problems existing, #9 self-lubricating plain bearing is now adopted to substitute.Although this scheme can solve Leakage, but inner grease chamber is less than self-lubricating plain bearing (9S bearing) because of #9 self-lubricating plain bearing, bearing temperature rise overrun issues can be caused, although the problem of the leakage of oil that above-mentioned solution solves, but also bring the problem that temperature rise is transfinited, therefore, be badly in need of a kind of new structural design and solve Leakage, and the problem that temperature rise is transfinited can not be brought.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of self-lubricating plain bearing device for modifying, make it have more value in industry.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of by increasing oil catch, to improve self-lubricating plain bearing Leakage, and the self-lubricating plain bearing device for modifying that temperature rise can not be brought to transfinite.
Self-lubricating plain bearing device for modifying of the present utility model, comprises sliding bearing main body, and the suction side of described sliding bearing main body is provided with oil catch.
Further, the suction side of described sliding bearing main body is provided with installation guide surface, and described oil catch is arranged on this installation guide surface.
Further, the stepped structure of described installation guide surface, the step structure on oil catch matches with the step structure on this installation guide surface, so that oil catch is fixed on the positioning in sliding bearing main body.
Further, described oil catch is bolted on and installs on guide surface.
Further, described oil catch is made up of no-spark material.
Further, described oil catch is aluminium matter oil catch.
Compared with above-mentioned prior art, the utility model at least has the following advantages: the aluminium matter oil catch of increase can increase outer barrier ability, increases its anti-negative pressure ability, effectively prevents the oil leakage phenomenon produced because of negative pressure impact from occurring; The problem that simultaneously also there will not be temperature rise to transfinite.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model self-lubricating plain bearing device;
Fig. 2 is the structural representation of sliding bearing main body in Fig. 1;
Fig. 3 is the structural formula schematic diagram of oil catch in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1-3, a kind of self-lubricating plain bearing device described in the utility model one preferred embodiment, comprises sliding bearing main body 1, and the suction side of described sliding bearing main body 1 is provided with oil catch 2.
The suction side of described sliding bearing main body 1 is provided with installs guide surface 3, and described oil catch 2 is arranged on this installation guide surface 3.The stepped structure 4 of described installation guide surface 3, the step structure 5 on oil catch 2 matches with the step structure 4 on this installation guide surface 3, so that oil catch 2 is fixed on the positioning in sliding bearing main body 1.
Described oil catch 2 is bolted on to be installed on guide surface 3 (fitting surface of step structure 4).Described oil catch 2 is made up of no-spark material.Described oil catch 2 is aluminium matter oil catch.
Assembling process of the present utility model is as follows:
First a stair-stepping installation guide surface 3 (fitting surface of step structure 4) is processed in the rear end (suction side) of sliding bearing main body 1, for installing oil catch 2, before motor assembling sliding bearing main body 1, oil catch 2 is installed on the installation guide surface 3 of sliding bearing main body 1.
When the motor is running, wind direction motor center sucks, form the suction toward motor center, thus make sliding bearing main body 1 inside produce negative pressure, sliding bearing main body 1 blocking capability deficiency will make lubricant oil suck motor internal or overflow to sliding bearing main body 1 along balancing orifice, the aluminium matter oil catch 2 increased can increase outer barrier ability, increases its anti-negative pressure ability, effectively prevents the oil leakage phenomenon produced because of negative pressure impact from occurring; The problem that simultaneously also there will not be temperature rise to transfinite.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
