Abstract

A ball bearing comprises a bearing and a plurality of steel balls; the bearing is formed by inner rings and outer rings; the inner rings and the outer rings are provided with corresponding grooves; retaining frames are arranged inside the grooves; the steel balls are installed inside the grooves of the outer rings and the inner rings through the retaining frames. The ball bearing is characterized in that the interior of at least one of the plurality of steel balls is provided with a spherical oil storage chamber; the steel ball with the spherical oil storage chamber is provided with a thin hole; the diameter of the thin hole is 0.01 mm; the thin hole is communicated with the spherical oil storage chamber. The ball bearing is installed on a shaft and the shaft rotates to drive the inner rings, so that the steel ball with the spherical oil storage ball inside the groove rotates, oil inside the spherical oil storage ball is shed out from the thin hole due to the centrifugal effect during the rotating process, the lubricating effect is achieved, and the bearing service life is improved.

Description

Ball bearing

Technical field

The utility model relates to a kind of ball bearing, and more particularly, it relates to a kind of ball bearing of selflubricating.

Background technique

Ball bearing is the most frequently used a kind of bearing, common ball bearing is made up of inner ring, outer ring, one group of steel ball, because it is simple in structure, easy to use, therefore produce the most general, but during normal use, the lubricated of bearing is very important, the insufficient meeting of bearing lubrication causes wearing and tearing, can bearing lubrication undue, can increase resistance.

Model utility content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball bearing of selflubricating.

For achieving the above object, the utility model provides following technological scheme: a kind of ball bearing, comprise bearing and several steel balls, bearing is made up of outer ring and inner ring, in described outer ring and inner ring, there is corresponding groove, in described groove, there is retainer, described steel ball is arranged on by retainer in the groove of outer ring and inner ring, it is characterized in that: several described steel balls have at least an inside to have spherical shoe cream room, on the steel ball of described spherical shoe cream room, there is pore, the diameter of described pore is 0.01 millimeter, and described pore is communicated with spherical shoe cream room part.

By adopting technique scheme, ball bearing is arranged on axle, rotatingshaft, axle drives inner ring, thereby the steel ball that makes inside in groove be provided with spherical shoe cream room rotates, in the process of rotating, due to centrifugal action, oil in spherical shoe cream room can slowly be thrown out of from pore, thereby has reached lubricated effect, has improved the working life of bearing.

The utility model is further set to: there is spherical shoe cream room described each steel ball inside.

By adopting technique scheme, because the pore on steel ball only has 0.01 millimeter, the oil ratio at every turn throwing away is less, cannot reach the effect of sufficient lubrication, so be provided with spherical oil storage oil pocket on each steel ball, the lubrication effect playing can obtain certain lifting.

The utility model is further set to: described pore has two.

By adopting technique scheme, because the pore on steel ball only has 0.01 millimeter, the oil ratio at every turn throwing away is less, cannot reach the effect of sufficient lubrication, so by increasing the number of pore, the lubrication effect playing can obtain certain lifting.

The utility model is further set to: described steel ball is for to be made up of high-carbon-chromium bearing steel.

By adopting technique scheme, the ball hardness that high-carbon-chromium bearing steel is made is high, and high-carbon-chromium bearing steel steel ball is after high temperature returns and overdoes, and it adapts to operating temperature can be up to 250 degree.

The utility model is further set to: there is seal ring described groove both sides.

By adopting technique scheme, by setting up seal ring, make the inner sealing of ball bearing, prevent that the object of dust and so on from entering bearing inside.

Brief description of the drawings

Fig. 1 is the utility model ball bearing embodiment's sectional view;

Fig. 2 is the utility model ball bearing embodiment's partial enlarged drawing.

Reference character: 1, outer ring; 2, steel ball; 3, spherical shoe cream room; 4, pore; 5, retainer; 6, inner ring; 7, groove; 8, seal ring.

Embodiment

Referring to figs. 1 through Fig. 2, the utility model ball bearing embodiment is described further.

A kind of ball bearing, comprise bearing and several steel balls 2, bearing is made up of outer ring 1 and inner ring 6, in described outer ring 1 and inner ring 6, there is corresponding groove 7, in described groove 7, there is retainer 5, described steel ball 2 is arranged on by retainer 5 in the groove 7 of outer ring 1 and inner ring 6, it is characterized in that: several described steel balls 2 have at least an inside to have spherical shoe cream room 3, on the steel ball 2 of described spherical shoe cream room 3, there is pore 4, the diameter of described pore 4 is 0.01 millimeter, described pore 4 is communicated with spherical shoe cream room 3 parts, ball bearing is arranged on axle, rotatingshaft, axle drives inner ring 6, thereby the steel ball 2 that makes inside in groove 7 be provided with spherical shoe cream room 3 rotates, in the process of rotating, due to centrifugal action, oil in spherical shoe cream room 3 can slowly be thrown out of from pore 4, thereby reach lubricated effect, improve the working life of bearing.

There is spherical shoe cream room 3 described each steel ball 2 inside, described pore 4 has two, because the pore 4 on steel ball 2 only has 0.01 millimeter, the oil ratio at every turn throwing away is less, cannot reach the effect of sufficient lubrication, so be provided with spherical oil storage oil pocket on each steel ball 2, the lubrication effect playing can obtain certain lifting.

Described pore 4 has two, because the pore 4 on steel ball 2 only has 0.01 millimeter, the oil ratio at every turn throwing away is less, cannot reach the effect of sufficient lubrication, so by increasing the number of pore 4, the lubrication effect playing can obtain certain lifting.

Described steel ball 2 is for to be made up of high-carbon-chromium bearing steel, and steel ball 2 hardness that high-carbon-chromium bearing steel is made are high, and high-carbon-chromium bearing steel steel ball 2 is after high temperature returns and overdoes, and it adapts to operating temperature can be up to 250 degree.

There is seal ring 8 described groove 7 both sides, by setting up seal ring 8, make the inner sealing of ball bearing, prevent that the object of dust and so on from entering bearing inside.
