Abstract
The utility model discloses an outer wheel of a water pump bearing. The outer wheel of the water pump bearing comprises an outer wheel body (2), wherein a center hole (1) used for installing a bearing inner ring is formed in the outer wheel body (2), a first annular groove (1.1) used for installing a plurality of steel beads arranged in the circumferential direction is formed in one end of the center hole (1), the side wall of the first annular groove (1.1) is an inward-concave spherical face matched with the steel beads, a second annular groove (1.2) used for installing a plurality of steel beads arranged in the circumferential direction is formed in the other end of the center hole (1), a third annular groove (1.4) is formed in one end of the second annular groove (1.2), and a fourth annular groove (1.5) is formed in the other end of the second annular groove (1.2). The outer wheel of the water pump bearing can guarantee normal lubrication of the bearing.
Description
Technical field
The utility model relates to a kind of water pump bearing foreign steamer.
Background technique
Bearing plays the effect of supporting rotator in machinery.In the time that other parts produce relative movement each other on axle, be used for retainer shaft central position and control the parts of this motion.Many bearings need time-based maintenance, to prevent premature failure.Although some may need a small amount of maintenance as liquid bearing and magnetic bearing, most of bearing needs intermittent oiling and clean at high cycleoperation, and may need to adjust, with the impact reducing wear to greatest extent.Often there is an oil nozzle without sealing type bearings, intermittent oiling grease gun, or regularly fill oily lubricating cup.
There is at present a kind of water pump bearing foreign steamer, it comprises foreign steamer body, in described foreign steamer body, be provided with the center hole for bearing inner race is installed, one end in described center hole is provided with for several first ring connected in stars along the steel ball of circumferential arrangement are installed, the sidewall of described first ring connected in star is the interior concave spherical surface matching with steel ball, and the other end in described center hole is provided with the second annular groove for some balls along circumferential arrangement are installed.The water pump bearing foreign steamer of this structure has the following disadvantages above: rotate because there are ball and steel ball in bearing inside simultaneously, consume so more grease, can only rely at present the grease adding when mounted, it is very inconvenient that later stage is added grease for the gap between ball and steel ball, frictional force between ball and steel ball and foreign steamer is strengthened, make troubles to the normal work of bearing.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of and can ensure the normal lubricated water pump bearing foreign steamer of bearing.
The technical solution of the utility model is, a kind of water pump bearing foreign steamer with following structure is provided, it comprises foreign steamer body, in described foreign steamer body, be provided with the center hole for bearing inner race is installed, one end in described center hole is provided with for several first ring connected in stars along the steel ball of circumferential arrangement are installed, the sidewall of described first ring connected in star is the interior concave spherical surface matching with steel ball, the other end in described center hole is provided with the second annular groove for some balls along circumferential arrangement are installed, in center hole between described first ring connected in star and the second annular groove, be provided with the cavity of accommodating grease, one end of described the second annular groove is provided with the 3rd annular groove, the other end of described the second annular groove is provided with Fourth Ring connected in star, the internal diameter of described the 3rd annular groove and Fourth Ring connected in star is greater than the internal diameter of center hole.
The inwall of described the 3rd annular groove is interior concave spherical surface.
The outer wall middle part of described foreign steamer body is provided with two for the five rings connected in star of seal ring is installed.
The outer wall middle part of described foreign steamer body is provided with the tapped hole with cavity, in described tapped hole, has screwed sealing screw.
Adopt after above structure, the utility model compared with prior art, have the following advantages: owing to being provided with the cavity of accommodating grease in the center hole between described first ring connected in star and the second annular groove, ball and the steel ball of bearing inside are rotated, grease in cavity can provide the lubricated of long period, later stage can be played enough lubrication effects for the friction between ball and steel ball and between foreign steamer, brings convenience to the normal work of bearing.
As improvement, the inwall of described the 3rd annular groove is interior concave spherical surface, offers the enough spaces of steel, prevents that steel ball from going inwall to encounter.
As improvement, the outer wall middle part of described foreign steamer body is provided with two for the five rings connected in star of seal ring is installed, and increases sealing effect, simple in structure.
As improvement, the outer wall middle part of described foreign steamer body is provided with the tapped hole with cavity, in described tapped hole, has screwed sealing screw, can add grease, very convenient.
