Description
Technical field
The utility model relates to a kind of oil storage motor, particularly a kind of sealed type oil storage structural electromotor and fan.
Background technology
Motor is the core component of electronic product, the life-span of these parts has directly determined the life of product of most of product, and one of bearing in motor structure that to be it important, all must add lubricating oil between well-known axle center and bearing, reducing friction guarantees that these parts get normally operation, and certain lubricating oil has run off, friction between bearing just begins to increase, friction sound strengthens, and component wear accelerates the useful life of seriously reducing motor.Therefore how to guarantee that on structural design lubricating oil does not run off, become the problem of numerous technical staff's researchs, also obtained many achievements.The losing issue of lubricating oil is not all considered in initial design, has run off soon along axis direction in rotating running in the axle center, so motor rotation increased with regard to rubbing after a period of time, cacophonia, can't work soon; There is a kind of semi open model oil storage motor in existing design, as shown in Figure 1, middle pipe the latter half seals, can prevent that lubricating oil runs off from this side port, but also there is opening port between stator and the axle center, lubricating oil still can run off from this section mouth, and this scheme has delayed the loss of lubricating oil to a certain extent, but does not fundamentally solve the problem that lubricating oil runs off.
Summary of the invention
Technical problem to be solved in the utility model is how to prevent that lubricating oil runs off on the bearing, prolongs the motor purpose in useful life thereby reach.
In order to solve the problems of the technologies described above, the utility model has designed a kind of sealed type oil storage structural electromotor, comprises stator 2, axle center 3, bearing 5, middle pipe 4, and its middle (center) bearing 5 is embedded in the middle pipe 4; Middle pipe 4 one ends sealing, the other end slightly exceeds bearing 5; Axle center 3 is passed bearing 5, one distal process and is gone out middle pipe 4, and it is characterized in that: described motor also comprises oil seal cover 6; Described oil seal cover 6 is arranged in pipe 4 tops, is shaped as annular; Outer ring and middle pipe 4 upper edge close contacts, inner ring and axle center 3 close contacts, like this oil seal cover 6, middle pipe 4 and the axle center 3 common confined spaces that form are enclosed in bearing 5 and bearing 5 required lubricating oil in the described space.
The utility model has also designed a kind of sealed type oil storage structural electromotor fan simultaneously, and described fan adopts sealed type oil storage structural electromotor, comprises stator 2, axle center 3, bearing 5, middle pipe 4, and its middle (center) bearing 5 is embedded in the middle pipe 4; Middle pipe 4 one ends sealing, the other end slightly exceeds bearing 5; Axle center 3 is passed bearing 5, one distal process and is gone out middle pipe 4, and it is characterized in that: described motor also comprises oil seal cover 6; Described oil seal cover 6 is arranged in pipe 4 tops, is shaped as annular; Outer ring and middle pipe 4 upper edge close contacts, inner ring and axle center 3 close contacts, like this oil seal cover 6, middle pipe 4 and the axle center 3 common confined spaces that form are enclosed in bearing 5 and bearing 5 required lubricating oil in the described space.
Enforcement the utlity model has following beneficial effect: by increasing an oil seal cover at original semi open model oil storage motor, to also exist the opening port of revealing lubricating oil to blocking on the semi open model motor, effectively prevent the loss of lubricating oil, prolonged and guaranteed that associated components in the time that normal operation under the state of oil lubrication is arranged, has also just prolonged the useful life of motor; The electric motor fan that adopts prior art can run off and because lacking the lubricated different sound that occurs because of lubricating oil after 600 hours in the normal-temperature continuous operation, friction increase between mechanism components, thus affect desired product useful life, only have about 20000 hours.And adopt the sealed type oil storage structural electromotor fan of this improved, and different sound just can appear after fan moves 1200 hours continuously, prolongs about life expectancy to 30000 hour.
