Abstract
The utility model relates to a roller bearing, in particular to a cylindrical roller bearing with inner and outer large-chamfer rings. Mainly, the technical problems that in the prior art, the outer end faces of an inner ring and an outer ring of the bearing have no chamfer or have small chamfers so that in the assembling process, the end faces of the inner ring and the outer ring are easy to clamp on equipment to be assembled, and the bearing is difficult to assemble and is easy to wear are solved. The cylindrical roller bearing with the inner and outer large-chamfer rings comprises the inner ring (1) and the outer ring (2). A clamping spring (3) is arranged between the inner ring and the outer ring. The clamping spring is provided with a row of cylindrical rollers (4). The cylindrical roller bearing is characterized in that the corner positions of the end faces at the outer ends of the inner ring (1) and the outer ring (2) are provided with arc large chamfers (5).
Description
Technical field
The utility model relates to a kind of roller bearing, especially relates to a kind of roller bearing with big chamfering Internal and external cycle.
Background technique
Along with the development of technology, the level of integration of automobile hub bearing is more and more higher.Automobile has generally comprised inner ring, outer ring with bearing unit, is fixed with single-row by jump ring or the biserial roller between the Internal and external cycle.Chinese patent discloses a kind of hub-bearing unit, and (notice of authorization number: CN201671960U), it comprises flange plate, inner ring, outer ring, ball, interior jump ring, outer jump ring, and inner ring is installed in the end of flange plate outside; Described outer ring is installed in the root of flange plate outside, be provided with first raceway groove and second raceway groove of ring-type between outer ring and flange plate and the inner ring, first raceway groove is in flange plate end one side, second raceway groove is in flange plate root one side, in first raceway groove and second raceway groove, be provided with ball, roll by described two row's balls with flange plate and inner ring and be connected in the outer ring, interior jump ring is installed in first raceway groove, outer jump ring is installed in second raceway groove, the diameter of second raceway groove is greater than the diameter of described first raceway groove, and the ball in second raceway groove is more than the ball in first raceway groove; The flange plate end is provided with the crimping with the flange plate one, and crimping is close to an end of described inner ring; 18 balls are housed in first raceway groove, 20 balls are housed in second raceway groove; Inner ring also is provided with speed sensor outward, and speed sensor comprises magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automobile hub bearing (notice of authorization number: CN201401445), it comprises the flange plate inner ring, flange plate outer ring, inside race, ball and jump ring, the flange plate outer ring internal surface is provided with two outer raceways, respectively be provided with on flange plate inner ring and the inside race outer surface and the corresponding interior raceway of outer raceway, ball be placed in the jump ring inscribe interior raceway and outside between the raceway, have annular groove and step surface on the flange plate inner ring outer surface, be provided with annular retaining ring in the groove, inside race one end face is resisted against on the annular retaining ring, and the other end is resisted against on the step surface.But the inner ring in these two kinds of bearings, the exterior edge face of outer ring does not all have chamfering or chamfering is less, and when therefore assembling, the end face of Internal and external cycle is stuck on the equipment to be assembled easily, assemble comparatively difficultly, and weares and teares easily.
The model utility content
The utility model provides a kind of roller bearing with big chamfering Internal and external cycle, it mainly is that the exterior edge face that solves inner ring in the existing in prior technology bearing, outer ring does not all have chamfering or chamfering is less, when therefore assembling, the end face of Internal and external cycle is stuck on the equipment to be assembled easily, assemble comparatively difficult, and the easy technical problem of wearing and tearing etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of roller bearing of the present utility model with big chamfering Internal and external cycle, comprise inner ring and outer ring, be provided with jump ring between inner ring and the outer ring, jump ring is provided with the columna roller, and the edge of the outer end end face of described inner ring, outer ring has the big chamfering of circular arc.Edge at the outer end of inner ring, outer ring end face is provided with big chamfering, helps the assembling of product, and improves the quality of product.The outer surface of inner ring and the internal surface of outer ring all are provided with the plane, and the plane can be fitted on the cylindrical roller outer surface, are convenient to the rolling of cylindrical roller.The inside of inner ring is provided with through hole, can be used for other parts such as cross-under flange plate.
As preferably, the arc round angle of described big chamfering is 13-17 ゜.Generally be to adopt the guiding of 15 ゜ angles, help the assembling of bearing.
As preferably, have the appearance indent on the inner ring at described cylindrical roller two ends.Hold in the indent to be marked with grease, can at any time lubricant oil be injected between cylindrical roller and the inner ring, reduce the wearing and tearing of cylindrical roller, increase the service life.Hold indent simultaneously and can prevent that also dust from entering between tapered roller and the inner ring, further increase the service life.
Therefore, the utility model is provided with the big chamfering of circular arc at the edge of the outer end of inner ring, outer ring end face, help the assembling of product like this, and improve the quality of product, and the appearance indent is set on inner ring, can lubricate cylindrical roller at any time, the working life of whole roller bearing is longer, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: inner ring 1, outer ring 2, jump ring 3, cylindrical roller 4, big chamfering 5, appearance indent 6.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of roller bearing of this example with big chamfering Internal and external cycle, as Fig. 1, inner ring 1 and outer ring 2 are arranged, be provided with jump ring 3 between inner ring and the outer ring, jump ring is provided with columna roller 4, has on the inner ring at cylindrical roller two ends to hold indent 6.The edge of the outer end end face of inner ring, outer ring has the big chamfering 5 of circular arc, and wherein the arc round angle of big chamfering is 15 ゜.
During use, on flange plate, inner ring is fixed, can be made into employed roller bearing unit on the automobile by the crimping of snap ring, nut or flange plate in the cross-under of the inside of inner ring 1.
