Abstract
The invention discloses an externally penetrated oil lubricated bearing, which comprises a first inner ring, a second inner ring and an outer ring, wherein a first retainer and a first rolling ball are clamped between the first inner ring and the outer ring; a second retainer and a second rolling ball are clamped between the second inner ring and the outer ring; the first inner ring and the second inner ring are coaxially overlapped; two ends of an upper oil seal lean against on the first inner ring and the outer ring in a sealed manner; two ends of a lower oil seal lean against on the second inner ring and the outer ring in a sealed manner; and the upper oil seal and the lower oil seal are of the same structure and both have a trumpet-shaped oil seal lip opening. According to the externally penetrated oil lubricated bearing, fresh and flowable lubricating oil can always enter into the space between the inner rings and the outer ring of the bearing, so that the service life of the bearing is guaranteed and meanwhile the cooling effect of a wheel hub bearing is realized.
Description
Technical field:
The present invention relates to technical field of bearings, more specifically to a kind of bearing from outside oil-penetrating lubricating.
Background technique:
Existing bearing, particularly automobile hub bearing, be generally by after between the inner ring of lubricant grease injection bearing and outer ring, remains between the outer ring and inner ring of bearing, thereby reach the object of bearing lubrication with oil sealing.Its deficiency is: grease is with after a period of time, and lubrication effect can decrease, and affects like this working life of hub bearing.The hub bearing of high speed rotating easily generates heat, if the heat of hub bearing can not dispel the heat in time, can increase wearing and tearing and the thermal burn distortion of bearing.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provide a kind of bearing from outside oil-penetrating lubricating, it can remain between the inner ring of bearing and outer ring has fresh flowable lubricant oil to enter, and guarantees the working life of bearing, hub bearing is had to cooling-down effect simultaneously.
Technology solution of the present invention is as follows:
A kind of bearing from outside oil-penetrating lubricating, comprise the first inner ring, the second inner ring and outer ring, the first retainer and the first ball are clamped between the first inner ring and outer ring, the second retainer and the second ball are clamped between the second inner ring and outer ring, the first inner ring is together with the second inner ring concentric arranged superposed, two ends of upper oil sealing seal respectively and are pressed on the first inner ring and outer ring, two ends of lower oil sealing seal respectively and are pressed on the second inner ring and outer ring, upper oil sealing is identical with the structure of lower oil sealing, and upper oil sealing and lower oil sealing all have trumpet-shaped oil seal lip.
Described upper oil sealing is made up of oil sealing support ring and oil sealing rubber ring, oil sealing rubber ring is being coated the end face that oil sealing support ring contacts with the first inner ring with outer ring, the right surface elasticity of oil sealing rubber ring is pressed on the first inner ring, and oil sealing support ring and oil sealing rubber ring outer end sleeve are in the annular groove of outer ring.
Beneficial effect of the present invention is:
It can remain between the inner ring of bearing and outer ring has fresh flowable lubricant oil to enter, and guarantees the working life of bearing, hub bearing is had to cooling-down effect simultaneously.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged view at A place in Fig. 1.
In figure: 1, the first inner ring; 2, the second inner ring; 3, outer ring; 4, the first retainer; 5, the first ball; 6, the second retainer; 7, the second ball; 8, upper oil sealing; 9, lower oil sealing.
Embodiment:
Embodiment: see Fig. 1, shown in 2, a kind of bearing from outside oil-penetrating lubricating, comprise the first inner ring 1, the second inner ring 2 and outer ring 3, the first retainer 4 and the first ball 5 are clamped between the first inner ring 1 and outer ring 3, the second retainer 6 and the second ball 7 are clamped between the second inner ring 2 and outer ring 3, the first inner ring 1 is together with the second inner ring 2 concentric arranged superposed, two ends of upper oil sealing 8 seal respectively and are pressed on the first inner ring 1 and outer ring 3, two ends of lower oil sealing 9 seal respectively and are pressed on the second inner ring and outer ring 3, upper oil sealing 8 is identical with the structure of lower oil sealing 9, upper oil sealing 8 and lower oil sealing 9 all have trumpet-shaped oil seal lip 81.
Described upper oil sealing 8 is made up of oil sealing support ring 8a and oil sealing rubber ring 8b, oil sealing rubber ring 8b is being coated the end face that oil sealing support ring 8a contacts with the first inner ring 1 with outer ring 3, the right surface elasticity of oil sealing rubber ring 8b is pressed on the first inner ring 1, and oil sealing support ring 8a and oil sealing rubber ring 8b outer end sleeve are in the annular groove 3a of outer ring 3.
Working principle: the oil seal lip 81 of upper oil sealing 8 and lower oil sealing 9 is connected mutually with lubricant pipe respectively, lubricant oil is from flowing between the first inner ring 1 and the gap of the second inner ring 2 between the first inner ring 1, the second inner ring 2 and outer ring 3, in lubricant pipe, can constantly enter and flow out between the first inner ring 1, the second inner ring 2 and outer ring with the lubricant oil of pressure, when bearing is lubricated, bearing is also played to cooling effect.
