The inner ring 3 is nested in the inside of the middle outer ring 2, and the lateral surface of the inner ring 3 is provided with raceway；
The cylindrical roller 4 is installed between the middle outer ring 2 and the inner ring 3, and is located at the middle outer ring 2 and inner ring In 3 raceway.
It is preferred that the fit clearance between the outer ring 1 and the middle outer ring 2 is 0.05~0.1mm.
Further preferably, the raceway of 2 medial surface of middle outer ring is double rib raceways.
Further preferably, the raceway of 3 lateral surface of inner ring is no rib raceway.
Further preferably, square groove 11 there are two being symmetrical arranged on the inner sidewall of the outer ring 1, and two are described rectangular Slot 11 is arranged each along the width direction of outer ring 1.
Further preferably, the width of the square groove 11 is equal to bearing width+1mm, and the depth of the square groove 11 is equal to The depth of outer ring raceway.
Novel full complement cylinder roller bearing provided by the invention, it can be achieved that CARB annulus roller bearing function replacement, lead to The middle outer ring structure for adding lateral surface within the bearing as convex spherical is crossed, even if making to use conventional cylinder roller bearing in bearing, Remain to the technical effect for reaching CARB annulus roller bearing.Specifically, by the mating spherical surfaces between outer ring and middle outer ring, it can Realize bearing Self-aligning ability, and cylindrical roller can realize bearing without limitation axial displacement ability, therefore, through the invention The structure of the novel full complement cylinder roller bearing of offer designs, and the function of CARB annulus roller bearing not only may be implemented, but also Easy to process, high yield rate is, it can be achieved that yield increases substantially.
It should be understood that above general description and following detailed description be only it is exemplary and explanatory, not The disclosure can be limited.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets implementation of the invention Example, and be used to explain the principle of the present invention together with specification.
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, for those of ordinary skill in the art Speech, without creative efforts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram that the present invention discloses a kind of novel full complement cylinder roller bearing that embodiment provides；
Fig. 2 is the structural representation that the present invention discloses outer ring in a kind of novel full complement cylinder roller bearing that embodiment provides Figure；
Fig. 3 is cross-sectional view of the Fig. 2 along BB.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended The example of device being described in detail in claims, some aspects of the invention are consistent.
In view of in the prior art, there are processing technology complexity, high rejection rate, low outputs etc. to ask for CARB annulus roller bearing Topic, present embodiment provides a kind of novel full complement cylinder roller bearing of achievable CARB annulus roller bearing function replacement, Referring to Fig. 1, which is mainly made of outer ring 1, middle outer ring 2, inner ring 3 and cylindrical roller 4, wherein the medial surface in outer ring 1 Be provided with concave spherical surface raceway, middle outer ring 2 is nested in the inside of outer ring 1, is arranged concentrically with outer ring 1, the lateral surface of middle outer ring 2 be with Double rib raceways are arranged in the convex spherical that 1 medial surface of outer ring matches, the medial surface in middle outer ring 2, and inner ring 3 is nested in middle outer ring 2 Inside, the lateral surface of inner ring 3 is provided with no rib raceway, cylindrical roller 4 is installed between middle outer ring 2 and inner ring 3, and position In the raceway of middle outer ring 2 and inner ring 3.
Novel full complement cylinder roller bearing in above scheme can be real by the mating spherical surfaces between outer ring and middle outer ring The Self-aligning ability of existing bearing, and cylindrical roller can realize bearing without limitation axial displacement ability, therefore, regardless of whether in the presence of Shafting misaligns or has axial displacement, which can make load mean effort on the position of entire roller in one, The ability of advantageous distributed load makes friction and frictional heat maintain low-level, reduces the temperature of operation, effectively extends profit The service life of lubrication prescription and bearing.
Above-mentioned novel full complement cylinder roller bearing, since middle outer ring is to be arranged concentrically with outer ring, middle outer ring and outer ring The spherical profile radius heart within the bearing, processing gets up relatively easy, CARB annulus roller bearing compared to the prior art, Not only the process-cycle is short, at low cost, and high yield rate, and whole process is easily achieved, and reduces the degree-of-difficulty factor of production.
The specific assembling process of above-mentioned novel full complement cylinder roller bearing are as follows: first by cylindrical roller 4 be fitted into outer ring 2 In raceway, inner ring 3 is promoted again from roller set bore diameter then, forms an inner assembly, it is finally that this inner assembly is outer by being packed into In the raceway of circle 1, last assembly is completed.
For the ease of the flexible rotating between middle outer ring and outer ring, as the improvement of technical solution, by outer ring 1 and middle outer ring Fit clearance between 2 is designed as 0.05~0.1mm, can allow axial direction in the case where not causing additional axial force or friction Displacement.
In order to realize and facilitate the assembly of novel full complement cylinder roller bearing, referring to fig. 2, Fig. 3, in the inside of outer ring 1 Square groove 11 there are two being symmetrical arranged on wall, and two square grooves 11 are arranged each along the width direction of outer ring 1.
It is preferred that the width of square groove 11 is equal to bearing width+1mm, the depth of square groove 11 is equal to the depth of outer ring raceway, By the design of above-mentioned size, the assembly of bearing can be realized, while not influencing the intensity of outer ring also, improve the carrying of the bearing Ability.
Those skilled in the art after considering the specification and implementing the invention disclosed here, will readily occur to of the invention its Its embodiment.This application is intended to cover any variations, uses, or adaptations of the invention, these modifications, purposes or Person's adaptive change follows general principle of the invention and including the undocumented common knowledge in the art of the present invention Or conventional techniques.The description and examples are only to be considered as illustrative, and true scope and spirit of the invention are by following Claim is pointed out.
