Abstract
The utility model provides a sealed double-row angular contact ball bearing, wherein sealing devices are embedded on the two sides of the bearing and other technical measures are adopted to solve the problems of the conventional bearing in sealing, load bearing and high-temperature operation. The technical scheme is adopted specifically as follows: annular steel frameworks (3) are mounted in seal grooves (7) on the two sides of the bearing, and a fluororubber ring (4) is embedded between the steel frameworks (3) and an outer ring (1) as well as an inner ring (5) to form an embedded-type sealing structure; the sealing structure is in interference fit with the outer ring (1) and the inner ring (5); a cage gap (9) is controlled within 1.5mm; the axial radians of an inner rolling path of the outer ring (1) and an outer rolling path of the inner ring (5) are enlarged to keep a contact angle between 45 to 50 DEG; the bearing clearance is adjusted to range from 0.077 mm to 0.10mm; the 250 DEG C additional tempering is carried out on a bearing ring; and extreme pressure lithium-based grease LGEP 2 is used instead. The sealed double-row angular contact ball bearing has better technical effect: once the bearing is operated in a machine, the service life thereof is prolonged up to more than 60 days.
Description
Technical field
The utility model relates to double-row angular contact bal bearing, is specifically related to a kind of sealed double-row angular contact ball bearing.
Background technique
Double-row angular contact bal bearing can bear bigger radial and axial composite load and moment load based on radial load, is mainly used in the parts of restrictive axes and the displacement of shell bi-directional axial.Inclination between the inside and outside circle of double-row angular contact bal bearing is limited, allow the tilt angle to depend on bearing size, interior shape, parts clearance and act on power and moment on the bearing, and the maximum tilt angle that allows should guarantee can not produce too high additional stress in the bearing.If the super scope in tilt angle between the inside and outside circle of bearing can cause the bearing operation precise decreasing, increase running noise.Existing double-row angular contact bal bearing all based on nylon cages and brass retainer, satisfies the demands under conventional operating mode; But in complex working conditions such as dust, high temperature, bearing generation premature fatigue, damage foreshorten to about 30 days working life.The bearing that last machine damages is the lasso cracking mostly, and retainer torsional deformation, steel ball are partly burnt and spot corrosion fatigue.Can judge that thus cause damage of bearings that following 5 reasons are arranged: 1. bearing does not have sealing, a large amount of dust easily infiltrate bearing; 2. bearing does not have sealing, and is lubricated often because of high temperature runs off seriously, increases the bearing member friction; 3. the super scope of wrapping angle causes the bearing axially loaded to increase; 4. the play of bearing self is too small, at 0.005mm～0.010mm; 5. the operating temperature mobility scale is bigger, and conventional bearing is difficult to be suitable for.
Summary of the invention
The utility model provides a kind of sealed double-row angular contact ball bearing, by the bearing both sides are inlayed seal arrangement and taked other technical measures, addresses the above problem.
The utility model is taked following technological scheme: form bearing by outer ring (1), steel ball (2), inner ring (5), retainer (6) and retainer (8); Ring-type Steel Skeleton (3) is installed in the seal groove (7) of bearing both sides, between Steel Skeleton (3) and outer ring (1) and inner ring (5), is embedded fluorine rubber ring (4) and form inserted sealing configuration.
Described sealing configuration and outer ring (1) be interference fit, with inner ring (5) for interference fit.
The retainer gap (9) of described retainer (6) and retainer (8) is controlled in the 1.5mm.
Interior raceway in described outer ring (1) and the outer raceway of inner ring (5) strengthen axial radian, and wrapping angle is controlled at 45 °～50 °.
Described bearing is adjusted bearing clearance through the grinding outer fissure, and the control play is at (0.077mm～0.10mm).
Bearing ring is carried out 250 ° of additional tempering; Use extreme pressure lithium base lubricating grease LGEP 2 instead.
The utlity model has better technical effect: bearing reaches more than 60 days through using on the machine working life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 is a sealed double-row angular contact ball bearing structural representation;
The position of Sealing and bearing seal groove when Fig. 2 is the Sealing interference.
Illustration: after outer ring 1, steel ball 2, Steel Skeleton 3, fluorine rubber ring 4, inner ring 5, retainer 6, seal groove 7, retainer 8, retainer gap 9, the top seal interference 10, after the lower seal interference 11.
Embodiment
As shown in Figure 1, ring-type Steel Skeleton 3 is installed in the seal groove 7 of bearing both sides, between Steel Skeleton 3 and outer ring 1 and inner ring 5, is embedded fluorine rubber ring 4 and form inserted sealing configuration.
As shown in Figure 2, sealing configuration and outer ring 1 are interference fit with inner ring 5; By after the top seal interference 10 and the lower seal interference after 11, visible Steel Skeleton 3 and fluorine rubber ring 4 form the interference sealing with outer ring 1 and inner ring 5, prevent the intrusion of foreign matter effectively; Fluorine rubber is applied to wherein as a kind of effective high-temperature resistant rubber, and its Applicable temperature can reach 250 ℃, makes bearing seal not be higher than proper functioning under 250 ℃ the temperature.
See Fig. 1, the retainer gap 9 of retainer 6 and retainer 8 is controlled in the 1.5mm, and little gap steel ball is not easy to depart from roller surface, helps bearing and runs well.Strengthen raceway and the axial radian of inner ring 5 outer raceways in the outer ring 1, make steel ball 2 space in raceway increase, increase wrapping angle, wrapping angle is controlled at 45 °～50 °, improved bearing and born bigger thrust load performance.Bearing is adjusted bearing clearance through the grinding outer fissure, the control bearing clearance is at 0.077mm～0.10mm, has improved the performance that bearing bears greater impact load.
Bearing ring is carried out 250 ° of additional tempering heat treatment, and bearing ring not only has enough high-temperature stabilities under working environment like this, but also has improved impact-resistant ability.Make bearing can adapt to higher operating temperature; Lubricant oil is used extreme pressure lithium base lubricating grease LGEP 2 instead, and LGEP 2 is that mineral oil based lithium soap base grease thickens extreme pressure agent, includes solid lubricant, still can carry out good lubricating to bearing under high-temperature work environment.
