Abstract
The utility model relates to a bearing technology field, the definite tapered roller bearing that says so. The technical scheme who adopts does: a novel conical roller bearing, including outer lane, inner circle, tapered roller and holder, tapered roller installs between outer lane and inner circle through the holder, the holder main aspects be equipped with the jack catch that the radius vector is extended to the outside, be equipped with the draw -in groove on the main aspects inner circumference of outer lane, the jack catch clamps in the draw -in groove. The utility model discloses realize that inner circle, outer lane are inseparable to it is easy to assemble, and guarantee higher precision bearing width size, have the compact advantage of simple structure simultaneously.
Description
Technical field
The utility model relates to technical field of bearings, is specifically tapered roller bearing.
Background technique
Tapered roller bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway.Existing tapered roller bearing, generally comprising outer ring, inner ring, between described outer ring, inner ring, being provided with tapered roller and the retainer for installing tapered roller, when tapered roller bearing is installed, because inner assembly and outer ring are separable, so inner assembly and outer ring need to install respectively.And the inner assembly of bearing and outer ring are taken all at random, not assembly one by one, such shortcoming is: install cumbersome on the one hand, the width dimensions scattered error of bearing is larger on the other hand.
Summary of the invention
For overcoming the deficiency that prior art exists, the utility model provides a kind of inner ring, outer ring inseparable, thus conveniently installs, and ensures the novel tapered roller bearing of degree of precision bearing width size, has advantage simple and compact for structure.
For achieving the above object, the utility model provides following technological scheme: a kind of novel tapered roller bearing, include outer ring, inner ring, tapered roller and retainer, described tapered roller is arranged between outer ring and inner ring through retainer, it is characterized in that: the large end of described retainer is provided with the claw extended to radial outside, the large end inner peripheral surface of described outer ring is provided with draw-in groove, and described claw is installed in draw-in groove.
By adopting technique scheme, at the large end design claw of retainer, the large end inner peripheral surface of outer ring establishes draw-in groove, claw card fits in draw-in groove, the inner assembly and the outer ring that realize the formation of retainer, inner ring and roller are integrally connected, thus convenient installation, and ensure the bearing width size of degree of precision, retainer and outer ring is utilized to be integrally connected, simple and compact for structure.
The utility model is set to further: described claw for radially outside and extend to form towards axioversion, described claw root and retainer are integrally connected, the head of claw be have between retainer compressible between the elastomer of separate space, described draw-in groove has the spacing axial limiting face coordinated of conflicting with claw head axial end portion, and to conflict spacing spacing inclined-plane with the back side adaptation of claw.
By adopting technique scheme, claw snaps in after in draw-in groove, the axial limiting face of draw-in groove and spacing inclined-plane realize preventing the axial both direction of claw from deviating from draw-in groove, thus reach retainer and outer ring is integrally connected, claw is for tilting extend and coordinate corresponding axial limiting face and spacing inclined-plane, claw coordinates with draw-in groove reliably, and claw height low (namely the distance of claw radially extension is short), the cooperating structure of claw and outer ring is compact.
The utility model is set to further: the large end end of described retainer is towards radial outside upset and inclination vertically extends to form flanging, and described claw is located at the outer circumferential side of flanging.
By adopting technique scheme, the flanging that the large end of retainer itself overturn to side, outer ring, claw is located on flanging, thus the height of reduction claw, make compact structure, and structural strength is greatly, structural stability.
The utility model is set to further: described draw-in groove is the circular groove along outer ring inner peripheral surface.
By adopting technique scheme, adopting circular groove to coordinate with claw, having and coordinating reliably, advantage easy to process.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment novel tapered roller bearing structural representation;
Fig. 2 is part A partial enlarged view in Fig. 1;
Fig. 3 is the utility model specific embodiment retainer structural representation.
Embodiment
See accompanying drawing 1 to accompanying drawing 3, a kind of novel tapered roller bearing disclosed in the utility model, include outer ring 1, inner ring 2, tapered roller 3 and retainer 4, described tapered roller 3 is arranged between outer ring 1 and inner ring 2 through retainer 4, described retainer 4 greatly end is provided with the claw 41 extended to radial outside, the large end inner peripheral surface of described outer ring 1 is provided with draw-in groove 11, and described claw 41 is installed in draw-in groove 11.At the large end design claw of retainer, the large end inner peripheral surface of outer ring establishes draw-in groove, claw card fits in draw-in groove, the inner assembly and the outer ring that realize the formation of retainer, inner ring and roller are integrally connected, thus convenient installation, and ensure the bearing width size of degree of precision, utilize retainer and outer ring to be integrally connected, simple and compact for structure.Wherein draw-in groove 11 adopts the circular groove along outer ring inner peripheral surface to design, and facilitates claw to snap in cooperation, facilitates draw-in groove being processed to form.
In this specific embodiment, described claw 41 is for radially outside and extend to form towards axioversion, described claw 41 root and retainer 4 are integrally connected, the head of claw 41 be have between retainer 4 compressible between the elastomer of separate space 42, described draw-in groove 11 has the spacing axial limiting face 111 coordinated of conflicting with claw 41 head axial end portion 411, and to conflict spacing spacing inclined-plane 112 with the back side 412 adaptation of claw 41.Claw 41 stretches into after in draw-in groove 11, the front end 411(of claw 41 and claw head axial end portion 411) coordinate with axial limiting face 111 is spacing, axial limiting face adopts vertical plane design; The back side 412 of claw 41 is plane of inclination, and the spacing inclined-plane 112 of draw-in groove 11 coordinates with the back side 412 of claw 41 is spacing, thus makes claw spacing in draw-in groove, thus reaches retainer and outer ring is integrally connected; Claw is for tilting extend and coordinate corresponding axial limiting face and spacing inclined-plane, and claw coordinates with draw-in groove reliably, and claw height low (namely the distance of claw radially extension is short), the cooperating structure of claw and outer ring is compact.
Preferably, the large end end of described retainer 4 is towards radial outside upset and inclination vertically extends to form flanging 43, and described claw 41 is located at the outer circumferential side of flanging 43.The flanging that the large end of retainer itself overturns to side, outer ring, claw is located on flanging, thus reduces the height of claw, makes compact structure, and structural strength is large, structural stability.
