Provided is a bearing, including inner circle, outer lane and lie in the inner circle and the outer lane between holder and ball, the ball has a plurality ofly and the circumference equipartition is installed on the holder, one side of inner circle has integrated into one piece's first fender shoulder, second that one side of outer lane has an integrated into one piece keeps off the shoulder, and it is relative that first fender shoulder and second keep off the shoulder position, and the ball lies in first fender shoulder to be kept off between the shoulder with the second, and first fender shoulder and second keep off the shoulder and all have an interior cambered surface, the camber of the interior cambered surface that first fender shoulder and second fender were takeed on all with the camber of ball excircle is the same.

Description

A kind of bearing

Technical field

The utility model relates to a kind of bearing.

Background technique

The major function of bearing is supported mechanical solid of rotation, reduces the friction in its movement process, ensures its rotating accuracy.Bearing is divided into sliding bearing, joint shaft bearing and rolling bearing.That relatively commonly uses in rolling bearing comprises deep groove ball bearing, angular contact bearing and plane bearing.The basic structure of deep groove ball bearing and angular contact bearing includes inner ring, outer ring, steel ball and retainer.Deep groove ball bearing is identical with the inner ring structure of angular contact bearing, cylindrical all has the raceway groove for installing steel ball, the outer ring raceway both sides of deep groove ball bearing have two shoulder block, deep groove ball bearing outer ring raceway curvature is greater than the curvature with the steel ball of its angle contacting, and therefore deep groove ball bearing is applicable to bear larger radial load, less thrust load or Axial and radial connected load.And the outer ring raceway of angular contact bearing only has while be provided with shoulder block, and angular contact bearing outer ring raceway curvature is equal with the curvature of the steel ball of its angle contacting, therefore, angular contact bearing can bear single less radial load or larger thrust load, and duplex pairing use can bear bi-directional axial load.The main structure of plane bearing comprises Upper gasket, lower levelling plate and the retainer between upper and lower pad and ball, and plane bearing mainly bears thrust load.

To sum up, no matter be deep groove ball bearing, angular contact bearing or plane bearing, do not have and bear larger axis and the function of radial load simultaneously, use narrow limitation large.

Model utility content

The utility model is intended to provide a kind of bearing bearing larger thrust load and larger radial load, and this bearing has good concentricity simultaneously.

A kind of bearing in this programme, comprise inner ring, outer ring and the retainer between inner ring and outer ring and ball, ball has multiple and is circumferentially uniformly arranged on retainer, described inner ring while have integrated first shoulder block, described outer ring while have integrated second shoulder block, first shoulder block is relative with the second shoulder block position, ball is between the first shoulder block and the second shoulder block, first shoulder block and the second shoulder block all have intrados, and the first shoulder block is all identical with the curvature of described ball cylindrical with the curvature of the intrados of the second shoulder block.

The beneficial effects of the utility model are as follows: owing to being provided with the first shoulder block and the second shoulder block respectively at inner ring and outer ring, and ball is between the first shoulder block and the second shoulder block, therefore, in the axial direction, due to the effect of the first shoulder block and the second shoulder block, make this bearing can bear larger thrust load, and diametrically, due to the effect of inner ring and outer ring, make this bearing can bear larger radial load.And because the first shoulder block and the second shoulder block all have intrados, the first shoulder block is all identical with the curvature of ball cylindrical with the curvature of the intrados of the second shoulder block, ball uniform force, therefore, can guarantee that this bearing has good concentricity in use.

Further, the length of the first shoulder block and the second shoulder block is all greater than the length of ball bearing radius and is less than the length of ball diameter.By above-mentioned design, make the first shoulder block and the second shoulder block all be coated to the radius of ball with upper/lower positions in ball both sides, increase the surface of contact between ball and two shoulder blocks, increase the thrust load that bearing bears further.

Further, the inner side surface of described outer ring is outward-dipping inclined-plane, and the intrados of this inclined-plane and the second shoulder block is tangent.The inner side surface beveling of outer ring, facilitates the installation of inner ring and outer ring.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Embodiment

Below by embodiment, the utility model is described in further detail:

Reference character in Figure of description comprises: outer ring 1, inner ring 2, ball 3, first shoulder block 4, second shoulder block 5.

Bearing as shown in figure 1 and 2, retainer (not shown) and multiple ball 3 is provided with between inner ring 2 and outer ring 1, ball 3 circumference is uniform to be arranged on retainer, inner ring 2 while have integrated first shoulder block 4, make inner ring 2 L-shaped, outer ring 1 while have integrated second shoulder block 5, make 1 one-tenth, outer ring L shape, first shoulder block 4 is relative with the second shoulder block 5 position, such inner ring 2 and outer ring 1 fasten each other, ball 3 is between the first shoulder block 4 and the second shoulder block 5, and the length that the length of the first shoulder block 4 and the second shoulder block 5 is all greater than ball 3 radius cuts the length being less than ball 3 diameter.

In the present embodiment, the first shoulder block 4 and the second shoulder block 5 all have intrados, and the first shoulder block 4 is all identical with the curvature of ball 3 cylindrical with the curvature of the intrados of the second shoulder block 5.The inner side surface of outer ring 1 is outward-dipping inclined-plane, and the intrados of this inclined-plane and the second shoulder block 5 is tangent.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
