The utility model discloses can make the retaining ring and sell the inseparabler of axle laminating, the effort is bigger even, effectively prevents to sell the drunkenness of axle, and structural design is more reasonable, and intensity is higher, long service life, and simple process, production efficiency is high, does benefit to the auto -parts marketing and uses.
Description
[technical field]
This utility model relates to the technical field of car gage part, particularly the technical field of the automobile back-up ring of a kind of Anti-moving high intensity.
[background technology]
The fixing of parts on shaft is divided into axial restraint and circumferentially fixed.The method of axial restraint has: the shaft shoulder or the axle collar are fixed, fixed with shaft end ring or taper seat, fix with axle sleeve, fix with round nut, fix with circlip.Back-up ring mainly plays the effect of axial restraint, and wherein conical surface back-up ring is fixed with higher centering degree.The back-up ring of rolling bearing is equivalent to a movable rib, is used to grade roller, convenient installation.The structure of back-up ring has loose rib, separate thrust collar and guide ring.Adopting wire rod clicking technique to make, cross section is rounded.By its effect classification loose rib: a separable substantially flat packing ring, in or beyond it, part is used as centripetal cylinder roller bearing outer ring or inner ring rib.Separate thrust collar: have the separable circle of " L " tee section, is used for separating and guide each row roller.Rib is parallel to rotating direction the narrow convex shoulder of prominent raceway face, is used for supporting and guiding rolling element and keep it in bearing.Owing to automobile is relatively big in the side force of turning or slope operating mode, in order to prevent bearing pin from scurrying out, it is necessary to bigger axial restraint power.Generally axially bed knife relies on the big interference fit of bearing pin to provide, if adopting interference fit, it is necessary to very big pressure assembling force.This is higher to the requirement of press-loading device.Typically no this big press device, and during field maintenance, it is not easy to operation.Therefore to reduction pressure, and need bigger axial restraint power, use back-up ring to prevent the play of bearing pin.Current back-up ring is loose rib, and after installation, back-up ring and installed surface have certain interval, it is impossible to be entirely prevented from bearing pin play.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, the automobile back-up ring of a kind of Anti-moving high intensity is proposed, can making the tightr of back-up ring and bearing pin laminating, active force is bigger uniformly, effectively prevents the play of bearing pin, structural design is more reasonable, intensity is higher, long service life, and technique is simple, production efficiency is high, is beneficial to auto parts machinery marketing application.
For achieving the above object, the utility model proposes the automobile back-up ring of a kind of Anti-moving high intensity, including back-up ring body, described back-up ring body be shaped as annular, the top of described back-up ring body and bottom surface are horizontal plane parallel to each other, the medial surface of described back-up ring body is provided with back-up ring tooth, the quantity of described back-up ring tooth has some, described back-up ring tooth uniformly along back-up ring body radially around the medial surface being arranged on back-up ring body, described back-up ring tooth be shaped as the isosceles trapezoid that top gradually tapers up, the top of described back-up ring tooth is interior concaved circular cambered surface, the center of circle of described interior concaved circular cambered surface and the center of circle of back-up ring body differ, the root of institute's back-up ring tooth is concordant with the top of back-up ring body and bottom surface.
As preferably, the quantity of described back-up ring tooth is 10-16 sheet, and the length of described back-up ring tooth is between 1st/1st to four/5th of back-up ring body radius.
As preferably, the circular arc number of degrees of described interior concaved circular cambered surface are 15-25 degree, and described interior concaved circular cambered surface is vertical arc surface, and described interior concaved circular cambered surface is set to matsurface.
As preferably, the side of described back-up ring body is perpendicular, and the corner of described back-up ring body is provided with the first rounding.
The beneficial effects of the utility model: this utility model is by combining back-up ring body, back-up ring tooth, interior concaved circular cambered surface, through optimum experimental, can making the tightr of back-up ring and bearing pin laminating, active force is bigger uniformly, effectively prevents the play of bearing pin, structural design is more reasonable, intensity is higher, long service life, and technique is simple, production efficiency is high, is beneficial to auto parts machinery marketing application.
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment.
