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 consistent with the utility model.On the contrary, they be only with such as
The example of the consistent device of some aspects be described in detail in the appended claims, the utility model.
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.

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.
