Description
Technical field
The present invention relates to a kind of rolling bearing, more particularly to a kind of ball bearing.
Background technology
Bearing, is the important foundation parts of all kinds of mechanized equipments, its precision, performance, the life-span and
Reliability plays conclusive effect to the precision of main frame, performance, life and reliability.Can be used for really
Determine rotary shaft and other parts relative motion position, play the parts of supporting or guide effect.Its master
It is the mechanical rotary body of support to want function, is used to reduce mechanical load friction system of the equipment in transmission process
Number.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the class of sliding bearing two.
Ball bearing, belongs to the class of rolling bearing one, is mainly used in bearing radial load.The ball of prior art
Bearing is mainly made up of bearing outer ring, bearing inner race, retainer, rolling element and sealing ring.Retainer
Effect be to prevent rolling element from coming off, guiding rolling element rotated lubrication.In the field for running at high speed
Close, because the self-lubricating property of bearing is bad, it is impossible to which good storing lubricating grease, lubricating grease is due to height
Fast operation friction becomes lubricating oil, the seepage from sealing ring gap, causes bearing lubrication not enough, seriously
When can burn out a bearing.
The content of the invention
(1) technical problem to be solved
It is good that the technical problem to be solved in the present invention is to provide a kind of greasy property, disclosure satisfy that fortune at a high speed
The ball bearing of the condition of work for turning.
(2) technical scheme
In order to solve the above technical problems, the present invention provides a kind of ball bearing, including：Bearing outer ring 1,
Bearing inner race 2, retainer 3, rolling element 4 and sealing ring 5；The retainer 3 is by the rolling element
The outer surface of 4 inner surfaces for being fixed on the bearing outer ring 1 and the bearing inner race 2, makes the rolling
Kinetoplast 4 is evenly distributed between the bearing outer ring 1 and the bearing inner race 2；The sealing ring
The 5 left and right ends for being arranged on the bearing outer ring 1 and the bearing inner race 2；The retainer 3
Shrinkage pool 6 including being used to fix the rolling element 4；The retainer 3 also includes being used to store lubrication
The groove 7 of fat.
Further, the inner surface of the shrinkage pool 6 is spherical concave surface 8.
Further, the quantity of the shrinkage pool 6 is identical with the quantity of the groove 7.
Further, the sealing ring 5 is sheet material class stamping parts.
Further, the material of the retainer 3 is the composites such as folder cloth phenolic resin, is soaked
Saturating grease base oil.
(3) beneficial effect
The retainer of ball bearing of the present invention has the groove structure of storing lubricating grease, being capable of long-time storage profit
Consistent lubricant, under the condition of work for running at high speed, lubricating grease will not ooze because of centrifugal force from sealing ring gap
Leakage；Simple structure, low cost, greasy property is good.
Brief description of the drawings
Fig. 1 is the structural representation of ball bearing of the present invention；
Fig. 2 is the structural representation of ball bearing retainer of the present invention.
Wherein：It is bearing outer ring 1, bearing inner race 2, retainer 3, rolling element 4, sealing ring 5, recessed
Hole 6, groove 7, spherical concave surface 8.
Specific embodiment
Refering to Fig. 1~Fig. 2, the present invention provides a kind of ball bearing, including：In bearing outer ring 1, bearing
Circle 2, retainer 3, rolling element 4 and sealing ring 5；
Refering to Fig. 1, be fixed on rolling element 4 in the inner surface and bearing of bearing outer ring 1 by retainer 3
The outer surface of circle 2, makes rolling element 4 be evenly distributed between bearing outer ring 1 and bearing inner race 2；
Sealing ring 5 is arranged on the left and right end of bearing outer ring 1 and bearing inner race 2；Sealing ring 5 is by sheet material
Class stamping parts is made.
Refering to Fig. 2, retainer 3 includes being used to fix the shrinkage pool 6 of rolling element 4, the inner surface of shrinkage pool 6
It is spherical concave surface 8, using spherical shape, can limit rolling element 4 moves radially gap, in height
The radial vibration of retainer is reduced in the case of speed operating.Retainer 3 also includes being used to storing lubricating grease
Groove 7, the quantity of shrinkage pool 6 is identical with the quantity of groove 7.
Wherein：The material of retainer 3 is the composites such as folder cloth phenolic resin, is impregnated with lubricating grease
Base oil.
During assembling, lubricating grease first is filled in the groove 7 of retainer 3, rolling element 4 is fixed on guarantor
Hold on the shrinkage pool of frame 3, be placed on the outer surface of bearing inner race 2, with lubricating grease by rolling element 4 with
The gap of shrinkage pool 6 is filled up, it is adaptable to load rotation speed requirements occasion higher, loads onto bearing outer ring 1,
Upper sealing ring 5 is installed in the left and right both ends of the surface of bearing outer ring 1 and bearing inner race 2.
The above is only the preferred embodiment of the present invention, it is noted that for the art
For those of ordinary skill, on the premise of the technology of the present invention principle is not departed from, can also make some
Improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
