Abstract
The utility model relates to a high temperature deep groove ball bearing, which comprises an outer ring, an inner ring, a steel ball and half cages. The steel ball is arranged between the inner ring and the outer ring, the two half cages are riveted together by rivets, the steel ball is arranged in a pocket of the two half cages. A radius of curvature of an outer surface of the outer ring of the bearing is R500 mm, the contact area is small, the abrasion of a track is reduced to 40%, noises are reduced, a stress concentration can be avoided, the service life of the high temperature deep groove ball bearing is prolonged and twice as long as that of the traditional bearing, and the high temperature deep groove ball bearing essentially can be used in a two-way stretch transversal pulling clip bearing.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of zanjon ball high-temperature bearing.
Background technique
Deep groove ball bearing is simple in structure, and working service is convenient.Be mainly used to bear radial load, also can bear certain thrust load, when the radial internal clearance of bearing strengthens, have the performance of angular contact ball bearing, can bear bigger axial load.This type of bearing drag is big, and the limit speed height is adapted to run up.Therefore, be commonly used for the horizontal zip clip bearing of biaxial tension, use in orbit.But all there is shortcoming in design in traditional zip clip bearing (comprising imported bearing), the outer surface of bearing outer ring is columniform, stress is concentrated during use, when running up in orbit, serious wear to track, particularly the wearing and tearing that track caused in the corner are even more serious, thereby shortened the working life of bearing greatly.
The model utility content
The technical problems to be solved in the utility model is: a kind of zanjon ball high-temperature bearing is provided, has used in orbit mainly as the horizontal zip clip bearing of a kind of biaxial tension, alleviated the wearing and tearing to track, strengthened working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of zanjon ball high-temperature bearing, comprise outer ring, inner ring, steel ball and half retainer, between inner ring and the outer ring steel ball is installed, two and half retainers by closing-up together, steel ball is in the pocket hole of two and half retainers, and the radius of curvature of described outer ring outer surface is R500mm.
This zanjon ball high-temperature bearing is of a size of internal diameter 12mm, and external diameter 40mm, thickness are 11mm.
This zanjon ball high-temperature bearing is of a size of internal diameter 15mm, and external diameter 42mm, thickness are 11mm.
This zanjon ball high-temperature bearing is of a size of internal diameter 12mm, and external diameter 34mm, thickness are 10mm.
The beneficial effects of the utility model are: this bearing outer ring outer surface curvature radius R500mm, area of contact reduces, wearing and tearing have been alleviated to track, reduce noise, can prevent simultaneously that stress is concentrated, strengthened working life, compared traditional bearing and improved 30% working life, the track wear extent reduces 40%.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of zanjon ball high-temperature bearing, comprise outer ring 1, inner ring 2, steel ball 3 and half retainer 4, steel ball 3 is installed between inner ring 1 and the outer ring 2, two and half retainers 4 by closing-up together, steel ball 3 is in the pocket hole of two and half retainers 4, and the radius of curvature of described outer ring 1 outer surface is R500mm.
Zanjon ball high-temperature bearing of the present utility model is a nonstandard bearing, and size is internal diameter 15mm, and external diameter 40mm, thickness are 11mm.This bearing is mainly used in the horizontal zip clip bearing of biaxial tension.
Zanjon ball high-temperature bearing of the present utility model is different with traditional bearing structure, and the bearing outer ring outer surface curvature radius is R500mm, has reduced area of contact, thereby can alleviate the track wearing and tearing, prevents that stress is concentrated, has strengthened working life.By check, compare with traditional bearing, improved 30% working life, the track wear extent has reduced 40%.
More than show and only described this practical major character and inventive point.Those skilled in the art should understand, and the utility model is not restricted to the described embodiments.Under the prerequisite that does not break away from point of the present invention and protection domain, the utility model also has various variations, and these changes and improvements all will fall in the claimed scope.The claimed scope of the utility model is limited by appending claims and equivalent thereof.
