Rolling friction exists between the rolling body and the inner ring and the outer ring, the rolling body is provided with an oil storage cavity, lubricating oil is installed in the oil storage cavity, the oil storage cavity is communicated with a rolling rubbing surface of the rolling body through two or more than two capillary oil tubes, and oil outlets of the capillary tubes are distributed on the rolling rubbing surface of the rolling body. The lubricating oil is installed in the oil storage cavity of the rolling body of the rolling body oil storage self-lubricating bearing, the lubricating oil permeates to the rolling rubbing surface of the rolling body through the capillary tubes, and the rolling body is lubricated. The rolling body oil storage self-lubricating bearing can be used for high-speed revolving parts, oil does not need to be added constantly, no special oiling way is needed, and mechanical design, processing and operation cost are reduced greatly.
Description
Affiliated technical field
The utility model relates to field of bearings, is specifically related to a kind of roll body oil storage self oiling bearing.
Background technique
Bearing uses extremely extensive in machinery, and its model numerous in variety is different, be loaded on slide or axial workpiece that rotation requires fixing on, be used for reducing friction, improve the working life of machinery.Wherein because the wear rate of rolling friction far below sliding friction, the utilization of rolling bearing is also extensive.
But rotation at a high speed still makes the roller of rolling bearing usually because of wearing and tearing damage, and in order further to reduce rolling friction, how on its roller, to add lubricant oil or lubricating grease.Though lubricating grease be solid-state meeting attached to above the roller, add in the time of when not required, how long have more than is neededly make; Just there is not much left for lubricating grease on the rolling friction face of roller, can't effectively form oil film, must add once more; And lubricant grease usually drops, not easy to clean.And grease lubrication usually can't be satisfied some high speed rotating requirements.Though the effect of oil lubrication is pretty good, need to add constantly, oil channel structures is comparatively complicated, has increased mechanical cost of production greatly; The fuel consumption of oil lubrication is also bigger, needs special oil pump simultaneously, and it is higher to consume energy.
Summary of the invention
To above problem, the utility model provides in a kind of roll body shoe cream room and stores lubricant oil, the roll body oil storage self oiling bearing that can be when bearing operation automatically the surface of roll body be lubricated.
The utility model solves the technological scheme that its technical problem adopted: this roll body oil storage self oiling bearing is a rolling bearing; Comprise roll body, outer ring, inner ring, being between said roll body and the Internal and external cycle rolling friction has a shoe cream room in the said roll body; In the said shoe cream room lubricant oil is housed; Through two or more capillary oil pipe, with the abrasive tumbling surface UNICOM of roll body, the oil outlet of said capillary oil pipe is distributed in the abrasive tumbling surface of roll body.
As preferably, said roll body is a hollow ball, and said shoe cream room is positioned at the roll body center, is a spherical cavity.
As preferably, said capillary oil pipe straight line runs through ball roll body center.
As preferably, there is the filling medium of oil absorption said shoe cream room inside.
As preferably, roll body is a hollow cylindrical roller, and said shoe cream room is positioned at the cylindrical roller axle center, is a cylindrical cavity.
The beneficial effect of the utility model is: store lubricant oil in the roll body shoe cream room of this roll body oil storage self oiling bearing; These lubricant oil are penetrated into the abrasive tumbling surface of roll body through the capillary oil pipe, and it is comparatively even that hydraulic fluid port is distributed on the oil film that the abrasive tumbling surface makes the lubricant oil of infiltration form, and improved lubrication effect greatly; Filling medium in the shoe cream room can keep can not permeating light fast in the shoe cream room; Can use for a long time, this bearing can carry out oil lubrication to roll body voluntarily, can be used for high speed rotating spare; Refuel in the time of when not required, need not special oiling oil circuit; Use this bearing, can reduce design, processing and the operating cost of machinery greatly.

Fig. 2 is the structural representation of spheroid among the roll body oil storage self oiling bearing embodiment 1.
Fig. 3 is the structural representation of roll body oil storage self oiling bearing embodiment 2 roll bodies.
Fig. 4 be roll body oil storage self oiling bearing embodiment 3 roll bodies structural representation.
Embodiment
Below in conjunction with embodiment the utility model is further specified:
Shown among Fig. 1; The self oiling bearing of roll body oil storage described in the embodiment 1 is a rolling bearing; Comprise roll body 1, inner ring 2, outer ring 3, be rolling friction, the each several part part of said roll body oil storage self oiling bearing between said roll body 1 and inner ring 2, the outer ring 3; All make with reference to the standard of deep groove ball bearing like inner ring 2, outer ring 3 sizes, the installation process of this kind bearing is also with reference to deep groove ball bearing.
Its main distinction is, and is as shown in Figure 2, is hollow ball like said roll body 1; Said shoe cream room 11 is positioned at the roll body center, is a spherical cavity, and this spherical cavity is a shoe cream room 11; In the said shoe cream room 11 lubricant oil 5 is housed; Through two or more capillary oil pipe 12, with the abrasive tumbling surface UNICOM of roll body 1, the oil outlet of said capillary oil pipe 12 is distributed in the abrasive tumbling surface of roll body 1.Capillary oil pipe 12 is the superfine straight shape chambeies of a kind of machine, and the diameter of capillary oil pipe 12 is directly proportional with shoe cream room 11 volume sizes with roll body 1, and enough slow for the speed that guarantees capillary oil pipe 12 oil impregnates, the diameter of capillary oil pipe 12 is less than 50 microns.This miniature capillary oil pipe 12 adopts laser beam machining, adopts pulse laser to penetrate the georama center, can form the capillary oil pipe 12 of two symmetries.After processing the capillary oil pipe 12 of roll body 1, can use the high pressure oil gun in shoe cream room 11, to inject lubricant oil.This roll body oil storage self oiling bearing can lubricate roll body 1 by penetrating lubricant oil in the capillary oil pipe 12 when in use.Being uniformly distributed with of capillary oil pipe 12 can guarantee to lubricate evenly because this Lubricants belongs to oil lubrication, can be used for high-speed rotating shaft.Need not fuel-servicing equipment and refuel structure.
As further improvement, as shown in Figure 3, be the embodiment 2 of roll body 1, there is the filling medium 6 of oil absorption said shoe cream room 11 inside, can slow down the time that lubricant oil outwards soaks in the shoe cream room 11 so greatly, increase the working life of roll body oil storage self oiling bearing.
As shown in Figure 4, for roll body oil storage self oiling bearing embodiment 3 roll body 1a structural representation, said roll body 1a is a hollow cylindrical roller, said shoe cream room 11a is positioned at the cylindrical roller axle center, is a cylindrical cavity.The processing method of this roll body 1a is similar with the processing method of roll body 1 among the embodiment 1, produces hollow cylindrical roller earlier, uses the method processing capillary oil pipe 12a of pulse laser punching then, and similarly method is injected oil to shoe cream room 11a.Use the roller bearing of this roll body 1a, be embodiment 3 roll body oil storage self oiling bearing.Beneficial effect is the same.
