Description

Oil-filled rolling bearing for resisting axial bearing capacity

Technical Field

The utility model relates to a bearing technical field specifically is a mend oily antifriction bearing for resisting axial bearing capacity.

Background

A rolling bearing is a precise mechanical element that reduces friction loss by changing sliding friction between a running shaft and a shaft seat into rolling friction. The rolling bearing generally comprises four parts, namely an inner ring, an outer ring, a rolling body and a retainer, wherein the inner ring is used for being matched with a shaft and rotating together with the shaft; the outer ring is matched with the bearing seat to play a supporting role; the rolling bodies are uniformly distributed between the inner ring and the outer ring by virtue of the retainer, and the shape, size and number of the rolling bodies directly influence the service performance and service life of the rolling bearing; the retainer can enable the rolling bodies to be uniformly distributed and guide the rolling bodies to rotate to play a lubricating role. The rolling bearings in the prior art usually need to bear larger axial load, and most rolling bearings are weaker in axial bearing capacity, so that the rollers and the retainer are damaged in the operation process and the rollers fall off, and the rolling bearings can generate larger friction torque in operation, so that the rollers are seriously abraded in the operation process.

In order to achieve the above purpose, the utility model provides an oil-supplementing rolling bearing for resisting axial bearing capacity, which comprises an inner ring and an outer ring, a rolling cavity is formed between the outer wall of the inner ring and the inner wall of the outer ring in a combined manner, a retainer is arranged on the rolling cavity, a plurality of rollers are filled on the retainer, two bearing rings for clamping the retainer after combination are arranged in the rolling cavity, the two bearing rings are arranged in a circular ring shape and respectively abut against and are buckled on the two sides of the retainer, a plurality of fixing holes are arranged on the outer ring corresponding to the two bearing rings and penetrate in the axial direction of the outer ring, a fixing column is movably arranged on the fixing holes, one end of the fixing column penetrates into the rolling cavity and is connected with the side wall of the bearing rings, the other end of the fixing column is arranged at the opening of the fixing holes, an oil filling hole is arranged on the end surface of the fixing column, an oil outlet hole for exposing or retracting the fixing hole when the fixing column moves is arranged on the outer wall of the fixing column, the oil outlet hole is communicated with the oil filling hole.

The technical scheme is adopted, and the method has the advantages that: the two bearing rings are combined to clamp the retainer, so that the retainer cannot deviate or be damaged when the bearing bears an axial load, a roller in the retainer is ensured to still roll on the running track, and the bearing rings are connected with the fixed columns on the outer ring, so that the bearing rings cannot deviate or shake during running, the inner ring usually rotates during running of the bearing, the bearing rings do not contact with the outer wall of the inner ring, and the rotating speed of the bearing is ensured not to be influenced; when the bearing moves for a period of time, the fixed column can be rotated by operating personnel, make the fixed column move down one end distance, oil outlet on the fixed column outer wall exposes the fixed orifices and exposes in the rolling intracavity this moment, operating personnel can carry out the oiling to the rolling intracavity through outside syringe, the setting of above-mentioned technique ensures that the bearing can not appear the phenomenon that the grease exhausts in operation a period back bearing inside, further ensure the normal operating of bearing, avoid the problem that operating personnel need frequently change the bearing after the grease consumes totally, and the setting of mending oil makes the bearing can receive the influence of lubricating oil and keep the rotational speed when the operation, ensure that the bearing also can keep normal rotational speed under the condition of long-time operation.

The utility model discloses further set up: the fixing columns are in threaded fit with the fixing holes, one ends of the fixing columns, which are used for penetrating into the rolling cavities and connected with the side walls of the bearing rings, are transfer ends, through holes for the insertion of the transfer ends are formed in the side walls of the two bearing rings, and the through holes are in threaded fit with the transfer ends.

The technical scheme is adopted, and the method has the advantages that: screw-thread fit sets up between fixed column and the fixed orifices, and the through-hole sets up with the also screw-thread fit of switching end, and the setting of above-mentioned technique makes being connected between fixed column and the carrier ring more stable, if when the carrier ring bears the axial force, because the screw-thread fit between fixed column and the fixed orifices, so the carrier ring can not squint or rock, and further two carrier rings of assurance can continue to carry out the centre gripping to the holder, avoid keeping the holder skew or rock and lead to the skew track of roller in bearing operation in-process.

The utility model discloses further set up: the fixed column is used for the one end that flushes with the fixed orifices opening part and is the oiling end, oiling end periphery wall facing upward is equipped with the leak protection circle, the laminating of leak protection intra-annular perisporium and oiling end periphery wall, the laminating of leak protection circle periphery wall and fixed orifices inside peripheral wall.

The technical scheme is adopted, and the method has the advantages that: the leakage-proof ring is arranged to further prevent the grease in the rolling cavity from leaking out through the fixing hole.

The utility model discloses further set up: and the oil injection end face of the fixed column is provided with a through groove for an operator to rotate the fixed column after inserting a screwdriver.

The technical scheme is adopted, and the method has the advantages that: when needs oiling, operating personnel can insert logical groove and rotate instruments such as screwdrivers through instrument such as screwdriver for the fixed column can rotate smoothly, and the setting up of leading to the groove makes things convenient for operating personnel to rotate the fixed column, ensures that the oil outlet can expose to the roll intracavity smoothly.
