Abstract
The invention discloses an oil slinger of a centrifugal pump bearing. The oil slinger comprises a pump shaft, and an oil slinger body, wherein two sets of trapezoidal grooves are formed in the outer circle of the pump shaft; multiple trapezoidal convex blocks A are uniformly arranged on the inner ring of the oil slinger body; multiple trapezoidal convex blocks B are uniformly arranged on the outer ring of the oil slinger body; and a rectangular shallow groove is formed in the outer ring of the oil slinger body, and is arranged between the two sets of trapezoidal convex blocks B. The oil slinger of the centrifugal pump bearing is simple in structure, is easy to machine and mold, largely increases the surface area, increases the oil quantity, and can more sufficiently achieve a lubricating effect on the pump shaft.
Description
Technical field
The present invention relates to the lubrication accessory of pump apparatus, refer more particularly to a kind of centrifugal pump bearing disc.
Background technique
Disc is that a kind of for ensureing that bearing has the mechanical parts of good lubrication effect, the rotation with bearing takes the lubricant oil below bearing to bearing, makes lubricant oil play the effect of lubrication, flushing, cooling to bearing.Disc form structure conventional is at present mainly annular, and its sense of rotation is consistent with the rotation direction of pump shaft, and drive disc to rotate by pump shaft, in disc rotation process, its surface takes up lubricant oil and gets rid of the object playing lubrication to bearing.But the outer shroud of general disc and inner ring are all limited area of smooth surface, its side and ring body end face, get rid of oil mass to be very restricted, particularly for the pump shaft that power is larger, if for shortage of oil, the wearing and tearing of pump shaft and sliding bearing will be caused to aggravate and even damage bearing.In addition, because conventional disc inner ring end face is smooth, the finite rate that pump shaft drives ring body to rotate, the amount causing ring body to take up lubricant oil is also restricted.
China Patent No. is 201020169633.2, denomination of invention is a kind of disc, and it gets rid of oily body and comprises internal surface and outer surface, and internal surface and outer surface are zigzag fashion, during work, disc is followed pump shaft and is rotated, and because internal surface is zigzag fashion, really increases the frictional force between disc and pump shaft, but zigzag internal surface can damage pump shaft, simultaneously with the rotation of pump shaft high speed, sawtooth also can be worn, and shortens the working life of disc.
China Patent No. is 201320849034.9, denomination of invention is centrifugal pump bearing disc, in order to improve the oil mass that disc takes up further, the beveled counterbore of getting rid of oilhole is provided as in the both sides of disc body, but this some holes reduces the mechanical strength of disc undoubtedly, disc is counterbore place fracture from the side easily.
Summary of the invention
The object of the invention is to solve above-mentioned Problems existing.
The present invention is achieved in that a kind of centrifugal pump bearing disc, comprises pump shaft, disc body, it is characterized in that: described pump shaft cylindrical is provided with two groups of trapezoidal grooves; Described disc body inner ring is evenly provided with some trapezoidal projection A, and disc body outer shroud is evenly provided with some trapezoidal projection B, and disc body outer shroud is provided with rectangle shallow slot, and rectangle shallow slot is arranged between two groups of trapezoidal projection B.
Further, described disc body comprises semicircular ring A and semicircular ring B, and semicircular ring A and semicircular ring B is fixed by counterbore screw.
Further, two groups of trapezoidal projection B are provided with between described rectangle shallow slot and adjacent rectangle shallow slot.
Further, described trapezoidal projection B coordinates with trapezoidal groove.
Structure of the present invention is simple, be easy to machine shaping, and surface area improves greatly, and band oil mass increases, and can play lubrication more fully to pump shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of pump shaft of the present invention;
Fig. 3 is trapezoidal projection A vertical section structure schematic diagram in Fig. 1;
In figure: 1, disc body, 101, semicircular ring A, 102, semicircular ring B, 2, trapezoidal projection B, 3, rectangle shallow slot, 4, trapezoidal projection A, 5, counterbore screw, 6, pump shaft, 7, trapezoidal groove.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
With reference to accompanying drawing, a kind of centrifugal pump bearing disc, comprises pump shaft 6, disc body 1, it is characterized in that: described pump shaft 6 cylindrical is provided with two groups of trapezoidal grooves 7; Described disc body 1 inner ring is evenly provided with some trapezoidal projection A, and disc body 1 outer shroud is evenly provided with some trapezoidal projection B, and disc body 1 outer shroud is provided with rectangle shallow slot 3, and rectangle shallow slot 3 is arranged between two groups of trapezoidal projection B; Described disc body 1 comprises semicircular ring A and semicircular ring B, and semicircular ring A and semicircular ring B is fixed by counterbore screw 5; Two groups of trapezoidal projection B are provided with between described rectangle shallow slot 3 and adjacent rectangle shallow slot 3; Described trapezoidal projection A coordinates with trapezoidal groove 7.
During concrete enforcement, disc external annular surface is set to trapezoidal projection B, and relative to general ganoid disc, increase ring body surface and amass, band oil mass being increased, being convenient to throw away taking up lubricant oil, lubricating efficiency increases; And the inner ring of disc is provided with trapezoidal projection A and matches with the trapezoidal groove 7 of pump shaft 6, for generally smooth inner ring end face, the frictional force between ring body and pump shaft 6 can be increased, improve the speed that ring body rotates, increase the oil mass that disc takes up, make pump shaft 6 obtain sufficient lubrication effect; The present invention is simultaneously provided with the disc of counterbore relative to side, rectangle shallow slot 3 depth as shallow, improves disc mechanical strength.
Structure of the present invention is simple, be easy to machine shaping, and surface area improves greatly, and band oil mass increases, and can play lubrication more fully to pump shaft.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each constituent element not clear and definite in the present embodiment is realized.
