Abstract
The utility model discloses a shielding electric pump bearing and thrust disc structure. The structure comprises a shaft (1), a shaft sleeve (2) is sleeved outside the shaft (1), a bearing (3) may be arranged outside the shaft sleeve (2) in a relative rotation manner, a thrust disc (4) in key joint with the shaft (1) is also arranged on the shaft (1), the bearing (3) is disposed in a bearing seat (5), and a stator flange (6) and a rotor shielding housing (7) are arranged outside the bearing seat (5). The structure is characterized in that a groove (8) is arranged towards the direction of the bearing (3) on the thrust disc (4), and a plurality of lubricating oil passages (9) are arranged in the radial direction of the bearing (3) and are uniformly arranged on the bearing (3). The structure provided by the utility model is smart in design and reasonable in arrangement, lubrication effects of the bearing and the thrust disc are effectively raised, and the service life of the structure is prolonged.
Description
Technical field
The utility model relates to a kind of shielded electric-pump structure, particularly a kind of shielded electric-pump bearing, thrust disc structure.
Background technique
Bearing in shielded electric-pump, thrust disc are easily damaged partss, and in most cases, the fault of shielded electric-pump is all caused by them.Damage meeting moment of bearing, thrust disc causes the wearing and tearing of impeller, casing ring and stator and rotor housing to be scrapped, and in the working life of therefore improving bearing and thrust disc, to the raising of machine life, is vital.But the lubricated of existing structure middle (center) bearing, thrust disc belongs to passive lubricated, particularly when carrying out the conveying of easy gasifying liquid, between axle sleeve and bearing because lacking flow of fluid amount, because fricative heat cannot be taken away, thereby cause the vaporizing liquid at this place, bearing is lost lubricated; And lose lubricated bearing, can produce more frictional heat, form vicious circle.When temperature reaches bearing burnt break temperature, bearing damage, the related damage that causes miscellaneous part in shielded electric-pump.Therefore need now a kind of Novel shielding electric pump that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can effectively improve bearing and thrust disc lubrication effect, the structure that extends its working life.
Technical solution of the present utility model is: a kind of shielded electric-pump bearing, thrust disc structure, comprise axle 1, outside axle 1, be socketed with axle sleeve 2, the outer relatively turnable bearing 3 that is provided with of axle sleeve 2, on axle 1, be also provided with the thrust disc 4 being connected with axle 1 key, bearing 2 is positioned at bearing support 5, at bearing support 5, is outside equipped with stator flange 6 and Rotor can 7, it is characterized in that: the direction towards bearing 3 on described thrust disc 4 is provided with groove 8, in the footpath of bearing 3, be upwards provided with grease channel 9.
Described grease channel 9 is a plurality of, and is evenly distributed on bearing 3.
Compared with the existing technology, tool has the following advantages the utility model:
The shielded electric-pump bearing of this kind of structural type, thrust disc structure, it is simple in structure, design ingenious, rationally distributed, it is for the existing defect of passive lubricated form of bearing and the thrust disc of traditional shielded electric-pump, at bearing, a plurality of grease channels have radially been offered, in the process that lubricant oil rotates at axle, under the effect of centrifugal force, be thrown in the gap between stator can and bearing support, and return to the gap between bearing support and axle sleeve along grease channel, play lubricated effect.This structure can allow lubricant oil circulate in bearing and thrust disc structure, prevents lubricated loss and the risk of freely not bringing.And its preparation process is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of shielded electric-pump bearing, thrust disc structure, comprise axle 1, outside axle 1, be socketed with axle sleeve 2, the outer relatively turnable bearing 3 that is provided with of axle sleeve 2, on axle 1, be also provided with the thrust disc 4 being connected with axle 1 key, bearing 2 is positioned at bearing support 5, at bearing support 5, be outside equipped with stator flange 6 and Rotor can 7, on described thrust disc 4, direction towards bearing 3 offers groove 8, this groove 8 can allow lubricant oil pass through behind the gap between bearing 3 and axle sleeve 2, enter the inner chamber of shielded electric-pump, for each parts are lubricated, in the footpath of bearing 3, be upwards also provided with a plurality of grease channels 9 simultaneously, and these grease channels 9 are uniformly distributed, under the effect of centrifugal force, be thrown to like this lubricant oil in gap between stator can and bearing support 5 and can again by grease channel 9, turn back to the gap between bearing 3 and axle sleeve 2, for the rotation of bearing 3 and axle 1 provides Cooling and Lubricator amount, and the utility model embodiment's groove 8 is arranged on thrust disc 4, compare with conventional construction in groove 8 is opened in to the structure on bearing 3, because thrust disc 4 does not rotate in the working procedure of shielded electric-pump, so lubricant oil is mobile more stable, smooth.
Claims (2)
1. a shielded electric-pump bearing, thrust disc structure, comprise axle (1), outside axle (1), be socketed with axle sleeve (2), the outer relatively turnable bearing (3) that is provided with of axle sleeve (2), on axle (1), be also provided with the thrust disc (4) being connected with axle (1) key, bearing (2) is positioned at bearing support (5), at bearing support (5), be outside equipped with stator flange (6) and Rotor can (7), it is characterized in that: the upper direction towards bearing (3) of described thrust disc (4) is provided with groove (8), in the footpath of bearing (3), be upwards provided with grease channel (9).
2. shielded electric-pump bearing according to claim 1, thrust disc structure, is characterized in that: described grease channel (9) is a plurality of, and is evenly distributed on bearing (3).
