Description
Technical field
The utility model relates to technical field of bearings, especially a kind of structure of thrust ball bearing.
Background technique
Thrust ball bearing is using the design that can bear thrust load when running at high speed, by the pad of the raceway ditch rolled with ball
Round lasso is constituted.Since lasso is seat cushion shape, thrust ball bearing is divided into flat bed pad-type and aligning seat seat cushion type
Two types.In addition, this bearing can bear axial load, but radial load cannot be born.The sealing of existing thrust ball bearing
Structure is designed as the clearance fit by outer cover and blowout patche more, and this sealing effect is very poor, is easily accessible dust or leakage rouge, and
And existing thrust ball bearing needs to add lubricant grease in use for some time, and it is complicated for operation, reduce the use effect of bearing
Fruit.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of thrust ball bearing, simple and reasonable, have compared with
Good sealing effect, while grease can be supplemented with duration from practical process, reduce repairing frequency.
The utility model provides a kind of thrust ball bearing, including blowout patche, seat ring, steel ball, retainer and punching press outer cover, described
Circumferentially spaced on retainer to be provided with several pocket slots, the steel ball rolling is arranged in pocket slot, and the retainer is arranged in axis
Between circle and seat ring, steel ball corresponding position is provided with the rolling groove for locking ball, the punching on the blowout patche and seat ring
Pressure outer cover is fastened on blowout patche and seat ring periphery wall, the punching press outer cover and blowout patche and outer ring clearance fit, the punching press
It is provided with seal groove between outer cover and seat ring, sealing ring is provided in the seal groove, is set between pocket slot on the retainer
It is equipped with fuel feed hole, the repairing hole being connected to fuel feed hole is provided on the pocket slot inner wall, oil storage sea is provided in the repairing hole
Silk floss, repairing hole opening, which also rolls, is provided with float ball, and the float ball and steel ball contradict and be arranged.
The beneficial effect being arranged in this way is: using the above scheme, seal groove is arranged and the external world can be effectively prevented in sealing ring
Impurity enters, while grease being effectively prevent to leak out.And retainer is arranged to this structure, in use, steel ball is not
Disconnected rotation, during the motion can contradict float ball, float ball can then compress oil storage sponge, so that in oil storage sponge
Oil liquid can be pressurized spilling, to realize continuous repairing in use, reduce the number of artificial addition lubricant grease, this
Kind structure is simple, is conducive to realize, effectively increases the using effect and service efficiency of the bearing.
The utility model is further arranged to repairing hole opening and is also symmetrical arranged there are two reseting leaf, described multiple
Position reed one end is connect with repairing hole opening, and the other end is free end and is extended into repairing hole that two reseting leafs are certainly
Oil outlet is formed by interval setting between end, the float ball contradicts between two reseting leafs.
The beneficial effect being arranged in this way is: using the above scheme, reseting leaf is arranged, avoids using rear float ball for a long time
It is pressed into repairing hole, increases the friction between steel ball, influence steel ball rolling, influence the practical of bearing, this structure can be with
Effectively float ball is avoided to be pressed into repairing hole, even if after being pressed into and float ball and reseting leaf it is inconsistent, friction compared with
It is small, it still may be rotated, reduce the influence to steel ball rolling.
The utility model is further arranged to be formed in fuel feed hole corresponding position for collecting oil liquid on the retainer
Liquid collecting convex ribs.
The beneficial effect being arranged in this way is: using the above scheme, setting liquid collecting convex ribs are convenient for the collection of oil liquid, so that oiling
When, oil liquid can be flowed into preferably in fuel feed hole, improve repairing efficiency.
