Abstract
The utility model relates to a kind of dust that prevents and enters the external sealing device of end cap in motor, particularly relates to a kind of simple and easy kinetic force of friction apparatus for demonstrating.Comprise device body, axle, hard baffle ring, spill cover plate, boss annulus, it is characterized in that, described body two ends end cap is provided with described boss, the central diameter of described boss annulus is greater than the diameter of motor shaft, described hard baffle ring is disk-shaped annular construction, with described axle interference fit, along with axle rotates, described spill cover plate coordinates with described boss annulus and is bolted, and the fit clearance formed with described hard baffle ring outer surface adopts oil sealing.The utility model structure is simple, and stopped the dust in external environment by the baffle ring arranged, steam etc. have the material of very major injury to motor internal, effectively improves motor useful life.
Description
Technical field
The utility model relates to a kind of motor end cover apparatus, particularly relates to a kind of dust that prevents and enters the external sealing device of end cap in motor.
Background technology
Motor has common requirements in commercial Application, and the industrial environment residing for it is also harsher.Special at the radiator shutter place of motor, larger air current flow can make dust and other impurities enter motor internal, special enter in electric motor end cap axis hole gap in motor and directly to enter into bearing portion, motor bearings generally adopts high-quality lubricating oil, be easy to attract dust, and the dust of absorption can hinder the running of motor, but also can increase the extra vibration frequency of motor.The dust guard more complicated that general motor is arranged, and there is consume.
Utility model content
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of dust that prevents enters the external sealing device of end cap in motor, comprise device body, axle, hard baffle ring, spill cover plate, boss annulus, it is characterized in that, described body two ends end cap is provided with described boss, the central diameter of described boss annulus is greater than the diameter of motor shaft, described hard baffle ring is disk-shaped annular construction, with described axle interference fit, along with axle rotates, described spill cover plate coordinates with described boss annulus and is bolted, and the fit clearance formed with described hard baffle ring outer surface adopts oil sealing.
Further, described hard baffle ring coordinates with described spill cover plate and boss ring gap, and axial cross section structure is up and down to the T-type structure become.
Further, described spill cover plate is circulus, and circumference is with boss and circular hole, and the interior diameter of annulus is equal with the ring interior diameter of described boss annulus.
Further, described boss annulus is a boss in described engine body end cover, and its upper surface is provided with screwed hole.
The good effect that the utility model has is:
The utility model structure is simple, and stopped the dust in external environment by the baffle ring arranged, steam etc. have the material of very major injury to motor internal, effectively improves motor useful life.
Accompanying drawing explanation
below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is that a kind of dust that prevents of the present utility model enters the external schematic diagram of sealing device of end cap in motor;
Fig. 2 is a kind of partial structurtes schematic diagram preventing dust from entering the external sealing device of end cap in motor of the present utility model.
Wherein, 1, body, 2, axle, 3, hard baffle ring, 4, spill cover plate, 5, boss annulus.
Embodiment
In order to make the utility model object, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is that a kind of dust that prevents of the present utility model enters the external schematic diagram of sealing device of end cap in motor.
A kind of simple and easy kinetic force of friction apparatus for demonstrating, comprise device body 1, axle 2, hard baffle ring 3, spill cover plate 4, boss annulus 5, it is characterized in that, described body 1 two ends end cap is provided with described boss 5, the central diameter of described boss annulus 5 is greater than the diameter of motor shaft, described hard baffle ring 3 is disk-shaped annular construction, with described axle 2 interference fit, along with axle rotates, described spill cover plate 4 coordinates with described boss annulus 5 and is bolted, and the fit clearance formed with described hard baffle ring 3 outer surface adopts oil sealing.
Wherein, hard baffle ring 3 and described spill cover plate 4 and boss annulus 5 matched in clearance, axial cross section structure is up and down to the T-type structure become.
Wherein, spill cover plate 4 is circulus, and circumference is with boss and circular hole, and the interior diameter of annulus is equal with the ring interior diameter of described boss annulus 5.
Wherein, boss annulus 5 is a boss on described body 1 end cap, and its upper surface is provided with screwed hole.
In installation process, first hard baffle ring 3 is enclosed within axle 2, interference fit, and baffle ring 3 one end is contacted with body 1 end cap, gap is formed with boss annulus 5, oil is filled with in gap, again spill cover plate 4 is coordinated with boss annulus 5, and by bolted, seal washer is added at spill cover plate 4 and boss annulus 5 contact surface, after installation, open motor, hard baffle ring 3 rotates with axle 2, because hard baffle ring 3 is very little with the fit clearance of spill cover plate 4 and boss annulus 5, ring seal structure is formed under the effect of lubricating oil, also maintain the lubrication needed for rotation of hard baffle ring 3.This sealing device is arranged on the two ends end cap of motor, the most easily enters dust greatly, need good protection at motor radiating blade place due to air-flow.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
