Description

Novel oil-supplementing retainer

Technical Field

The utility model relates to a bearing technical field specifically is a novel oil supplementation holder.

Background

At present, the retainer of the existing deep groove ball bearing is asymmetric, and the bearing is subjected to eccentric stress caused by the retainer during high-speed operation, so that the limit rotating speed of the bearing is restrained. Therefore, a retainer capable of self-locking rollers is developed in the prior art, the rollers are locked in an annular closed mode, the radial bearing capacity of the rollers in the retainer is increased by adopting the method, the rollers are abraded while the bearing limit rotating speed is increased, the service life of the rollers is greatly shortened, grease in the retainer cannot be supplemented, the friction loss between the rollers and the retainer pocket is increased, and the service life of the rollers is further shortened.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a novel mend oily holder leads to the problem that roller friction loss increases, life reduces for the unable replenishment of grease in solving prior art in the holder.

In order to achieve the purpose, the utility model provides a novel oil supplementing retainer, comprising a frame body, be provided with the pocket hole that a plurality of is used for the holding roller on the support body, be connected with the roof beam body between the adjacent pocket hole, the spout has been seted up towards adjacent pocket hole direction to the roof beam body, set up the trompil that switches on with the spout on the pocket hole inner wall, be provided with the slider on the spout, the slider slides along spout length direction and realizes the exposure or the withdrawal of slider on the trompil, be provided with on the spout inner wall and store up the fat cotton, the slider slides and extrudes the outflow that realizes storing up fat cotton interior grease to storing up the fat cotton, set up the oil transportation groove that supplies the grease to flow to the pocket downthehole from the spout.

The technical scheme is adopted, and the method has the advantages that: the pocket is filled in from the pocket hole outside to the roller, roller and slider contact make slider withdrawal trompil this moment, the slider slides and extrudees in the spout and stores up the fat cotton, make the fat in the storage fat cotton flow, the fat flows to the pocket hole in through the oil delivery groove and realizes the replenishment to roller surface grease, through the technique, make operating personnel when installing the roller, the grease can obtain the replenishment by oneself, do not need operating personnel to mend oil to the pocket hole one by one, and when the bearing operates, the roller also can make the grease flow to the pocket hole through extrusion slider and mend oil to the roller, reduce the friction torque that produces with the holder contact when the roller rotates, further avoid the roller life to reduce, and under the prerequisite that keeps bearing limit rotation, reduce the loss to the roller.

The utility model discloses further set up: the one end that the trompil was exposed to the slider is for mending the oil end, the slider is held for contradicting with the inconsistent one end of storing up the fat cotton, oil transportation groove one end sets up and is served at the benefit oil, and the other end setting is served at contradicting.

The technical scheme is adopted, and the method has the advantages that: the slider exposes the one end of trompil and is the end of mending oil, the slider is the end of contradicting with the one end that stores up the fat cotton and contact, when the slider slides in the spout, mend the oil end withdrawal trompil, the end extrusion of contradicting is stored up the fat cotton and is made the grease follow store up the fat cotton in outflow, and flow the pocket through defeated oil groove and realize the benefit oil to the roller in the hole, above-mentioned technical scheme makes in the grease can more quick outflow pocket, and defeated oil groove one end sets up and serve at the benefit oil, the roller contacts with the end of mending oil when filling in the pocket hole, can contact and lubricated roller with the roller the very first time when grease flows from the end of mending oil, avoid the grease to leak.

The utility model discloses further set up: the oil supplementing end corners are arranged in an arc shape.

The scheme is adopted, and the method has the advantages that: when the roller is plugged into the pocket hole, the roller is in angular contact with the oil supplementing end edge, the oil supplementing end edge is arranged in an arc shape, the roller is prevented from being damaged due to the fact that the oil supplementing end edge abrades the surface of the roller, and the service life of the roller is further prevented from being reduced.

The utility model discloses further set up: the oil supplementing end is provided with a rolling groove, a ball is arranged on the rolling groove in a rotating mode, a through hole communicated with the rolling groove is formed in the end face of the oil supplementing end, a part of the ball is exposed out of the through hole to achieve interference fit between the ball and the roller, and the diameter of the through hole is smaller than that of the ball.

The technical scheme is adopted, and the method has the advantages that: the ball rotates and sets up at the roll inslot, and roller and ball contact when the pocket hole is filled in to the roller, and the roller surface can not worn and torn to the ball, and the bearing during operation roller rotates at the downthehole internal rotation linkage ball of pocket, reduces the friction loss between roller and the downthehole wall of pocket, avoids roller life to reduce. The diameter of the through hole is smaller than that of the ball, so that the bearing is prevented from being damaged due to the fact that the ball falls off from the rolling groove.
