Abstract
The utility model pertains to bearing art, is a biserial cylindrical roller bearing with dust cap consisting of an outer ring, an inner ring, a loose rib, cylindrical rollers and an engineering plastics cage, both end faces of the bearing outer ring are provided with the dust caps, the engineering plastics cage is with the mode of that the cage is guided by the cylindrical rollers itself. The utility model has the advantages of that, the capacity of high rotation speed for the bearing was settled effectively, the carrying capacity of the bearing was strengthened, the service life of the bearing is increased by 50percent, and the temperature rise is decreased.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of Biserial cylindrical roller bearing with dust-proof cover.
Background technique
200 kilometers/hour bullet train axle boxes of railway motion speed bearing, working environment motion speed height, life-span and reliability requirement height, bearing temperature rise requires low, original structure is open type two cover single row roller bearings, the bearing speed capability is low, the life-span short, and retainer often occurs and fall the copper end, cause the bearing early fatigue, phenomenons such as temperature rise height.For overcoming the above problems, design a kind of Biserial cylindrical roller bearing of two sides band dust-proof cover.
Summary of the invention
The utility model proposes a kind of Biserial cylindrical roller bearing, can effectively prevent entering of dust, can prevent to get rid of oil simultaneously, help forming the oil circulation, keep the good lubrication oil film, be beneficial to improve the bearing rotating speed, improve bearing reliability and life-span with dust-proof cover.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Biserial cylindrical roller bearing of two sides band dust-proof cover.Be made up of outer ring 1, inner ring 2, loose rib 3, cylindrical roller 4 and engineering plastics cage 5, bearing outer ring 1 both ends of the surface have dust-proof cover 6, and engineering plastics cage 5 is cylindrical roller 4 bootstrap retainer modes.
The beneficial effects of the utility model are, have effectively solved the high speed capability of bearing, have strengthened the bearing capacity of bearing, and bearing life improves 50%.Reduced bearing temperature rise.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, outer ring, 2, inner ring, 3, loose rib, 4, cylindrical roller, 5, engineering plastics cage 6, dust-proof cover.
Embodiment
This bearing is 200 kilometers/hour bullet train axle boxes of railway motion speed bearing, is a kind of Biserial cylindrical roller bearing of two sides band dust-proof cover.Constituent elements is made up of outer ring 1, inner ring 2, loose rib 3, cylindrical roller 4, engineering plastics cage 5 and dust-proof cover 6.Bearing outer ring 2 both ends of the surface have dust-proof cover 6, can effectively prevent entering of dust, can prevent to get rid of oil simultaneously, help forming the oil circulation, keep the good lubrication oil film, are beneficial to improve the bearing rotating speed, improve bearing reliability and life-span; After adopting this design, effectively solved the high speed capability of bearing, strengthened the bearing capacity of bearing, bearing life improves 50%.Reduced bearing temperature rise.
