Abstract

The utility model discloses an anti-oil-leakage lubricating mechanism applied to a bearing. The anti-oil-leakage lubricating mechanism applied to the bearing can lubricate the bearing efficiently, and related components of a bearing machine do not need to be detached regularly in the lubricating process. The anti-oil-leakage lubricating mechanism applied to the bearing comprises an outer bearing seat and an inner bearing seat embedded into the outer bearing seat, wherein an O-shaped ring is arranged at the interval between the outer bearing seat and the inner bearing seat, the bearing is assembled in the inner bearing seat, engine oil used for lubricating the bearing is injected into the inner bearing seat, an oil-blocking disc used for preventing the engine oil inside the inner bearing seat from leaking is installed at the end of the inner bearing seat, the end of the inner bearing seat is sealed through a dustproof cover, the dustproof cover is provided with an inside ring groove and a concave port in the outer wall, an oil-throwing ring used for preventing the bearing inside the inner bearing seat from splashing oil is installed in the ring groove of the dustproof cover, and a framework oil seal used for preventing the wall surface of the oil-throwing ring from leaking oil is installed in the concave port in the outer wall of the dustproof cover.

Description

Oil-leakage-prevention lubricating structure for bearing

Technical field

The utility model relates to machine lubrication technical field, is specifically applied to the lubricated of bearing.

Background technique

At present, bearing lubricated mostly adopts known butter lubrication technology, this lubricating system not only to need regular dismounting parts to coat butter and is lubricated, has inefficient shortcoming, and easily bearing is caused to damage in unloading process, there is the shortcoming that reduces machine service life.

Model utility content

Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of oil-leakage-prevention lubricating structure for bearing is provided, it can high efficiencyly realize the lubricated of bearing, and greasing does not need regular dismounting bearing machine associated components.

The utility model solves the technological scheme that its technical problem adopts: for the oil-leakage-prevention lubricating structure of bearing, comprise outer bearing carrier and be bumped into the inner pedestal in outer bearing carrier, the gap between outer bearing carrier and inner pedestal is provided with O type circle; Bearing assemble is in inner pedestal; In inner pedestal, be injected with the machine oil for lubricating bearings;

The end of above-mentioned inner pedestal is provided with for preventing the oil baffle disc of the oil leakage of inner bearing inside, and the end of inner pedestal seals by dust cover; Dust cover is provided with inner ring recess and the recess of outer wall; In the ring recess of dust cover, be provided with for preventing the oil thrower ring of the bearing spilled oil in inner pedestal;

In the recess of the outer wall of above-mentioned dust cover, be provided with for preventing that the outside framework oil seal of leakage of oil from appearring in oil thrower ring wall.

Further: on above-mentioned dust cover, offer the oil hole that injects machine oil in promising inner pedestal.

Further: above-mentioned outside framework oil seal is Double-lip framework oil sealing.

The utility model compared with prior art has the following advantages:

The utility model, for the oil-leakage-prevention lubricating structure of bearing, first assembles O type circle between interior outer bearing, has played the effect of flinger ring; Secondly in order to realize oil lubricating, in the end of inner pedestal, set gradually oil baffle disc, oil thrower ring, dust cover and outside framework oil seal, not only prevent the leakage of machine oil, also prevented that machine oil from splashing and the seepage of machine oil, therefore can carry out very reliably oil lubricating; Compare traditional butter lubricated, the efficiency of oil lubricating is higher, and does not need to dismantle bearing and associated components thereof, has extended the working life of machine.

Description of reference numerals:

1-outer bearing carrier, 2-inner pedestal, 3-oil baffle disc, 4-oil thrower ring, 5-dust cover, 6-outside framework oil seal, 7-bearing, 8-O type circle.

Embodiment

Below in conjunction with drawings and Examples, the utility model embodiment is described:

Fig. 1 shows a kind of concrete real-time mode of the present utility model, as shown in the figure, the utility model is for the oil-leakage-prevention lubricating structure of bearing, comprises outer bearing carrier 1 and is bumped into the inner pedestal 2 in outer bearing carrier 1, and the gap between outer bearing carrier 1 and inner pedestal 2 is provided with O type circle 8; Bearing 7 is assemblied in inner pedestal 2; In inner pedestal 2, be injected with the machine oil for lubricating bearings;

The end of above-mentioned inner pedestal 2 is provided with for preventing the oil baffle disc 3 of the oil leakage of inner bearing 2 inside, and the end of inner pedestal 2 seals by dust cover 5; Dust cover 5 is provided with inner ring recess and the recess of outer wall; In the ring recess of dust cover 5, be provided with for preventing the oil thrower ring 4 of the bearing spilled oil in inner pedestal 2;

In the recess of the outer wall of above-mentioned dust cover 5, be provided with for preventing that the outside framework oil seal 6 of leakage of oil from appearring in oil thrower ring 4 walls.

Concrete, on above-mentioned dust cover 5, offer the oil hole of the interior injection machine oil of promising inner pedestal 2.

Preferably, above-mentioned outside framework oil seal 6 is Double-lip framework oil sealing, and the secondary lip of Double-lip framework oil sealing has further played dustproof effect, makes the dust sealing better effects if of whole mechanism.

The utility model is bumped into outer bearing carrier by inner pedestal after the space of inner pedestal and outer bearing adds " O " type circle, and then bearing is bumped into inner pedestal, with oil baffle disc, first the bearing machine oil of inner pedestal the inside is carried out to preliminary leakproof.Bearing at inner pedestal can spatter oil condition in operation process, in this case, utilize " oil thrower ring " to be bumped into the circle grain the inside of dust cover, in order to prevent that oil condition from appearring leaking in " oil thrower ring " wall, with one " outside framework oil seal ", be bumped into dust cover outer wall recess, finally with dust cover, inner pedestal carried out to encapsulation process.Therefore, the utility model has been avoided regularly dismantling bearing and has been coated butter, makes the infringement of matched bearings.Increase work efficiency, extend the life-span of bearing.

By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.

Do not depart from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
