[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making new labor are within the scope of protection of the present application.

[0034] In the description of the present application, it should be understood that the terms "upper", "lower", "top surface", "bottom surface", and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0035] As Figures 1-8As shown, the centering roller bearing retainer disclosed by the present application comprises a first circular ring 100, a second circular ring 200, a support beam 300 and a self-locking part 400, wherein the first circular ring 100 and the second circular ring 200 are arranged in parallel, a plurality of support beams 300 are arranged uniformly between the first circular ring 100 and the second circular ring 200, and a pocket hole 500 is formed between two adjacent support beams 300, one support beam 300 is connected with two self-locking parts 400, and the two self-locking parts 400 are arranged on the two sides of the support beam 300, respectively. Specifically, the cross section of the roller is circular, and the two self-locking parts 400 arranged on the two sides of the pocket hole 500 act on the two ends of the diameter of the circle or the vicinity of the two ends of the diameter of the circle, so as to limit the roller, that is, the two self-locking parts 400 act on the two ends of the roller arranged inside the pocket hole 500, so as to lock the roller inside the pocket hole 500. In use, the roller is arranged inside the pocket hole 500, one support beam 300 is connected with two self-locking parts 400, and the two self-locking parts 400 are arranged on the two sides of the support beam 300, respectively, so that the two self-locking parts 400 located in the pocket hole 500 can lock the roller inside the pocket hole 500, so that the roller rotates stably in the pocket hole 500 of the centering roller bearing retainer during the operation of the bearing. Therefore, the present application improves the stability of the roller installation, thereby improving the installation effect of the roller.

[0036] Further, in some embodiments of the present application, the self-locking part 400 and the support beam 300 are designed in one body, and the self-locking part 400 and the support beam 300 are integrally formed when the centering roller bearing retainer is produced, so as to improve the production efficiency of the centering roller bearing retainer.

[0037] In some other embodiments of the present application, the self-locking part 400 and the support beam 300 are designed in a split body, and when in use, the operator can replace different models of self-locking parts 400 according to the needs of the locking position and locking degree of the roller, so as to improve the use flexibility of the centering roller bearing retainer.

[0038] To optimize the above technical solutions, the support beam 300 comprises a mounting portion and a support portion, the mounting portion is arranged close to the inner ring of the first circular ring 100, the support portion is arranged close to the outer ring of the first circular ring 100, the mounting portion is provided with a mounting groove, and the mounting groove comprises a first groove wall 301 and a second groove wall 302. Specifically, the shape of the mounting groove includes but is not limited to V-shaped, U-shaped and the like. In use, the operator pushes the roller along the slotted portion of the mounting groove to the direction of the groove bottom, and one of the first groove wall 301 or the second groove wall 302 in direct contact with the roller is deformed to the other first groove wall 301 or second groove wall 302 not in direct contact with the roller, so as to facilitate the operator to install the roller. By arranging the mounting groove, the self-aligning roller bearing retainer has a deformation space when installing or dismounting the roller, the labor intensity of assembling the self-aligning roller bearing is reduced, and the roller can be quickly installed, dismounted or replaced, thereby improving the installation efficiency of the roller. Further, when producing the self-aligning roller bearing retainer, the self-aligning roller bearing retainer needs to be demolded, and by arranging the mounting groove, the self-aligning roller bearing retainer has a deformation space when demolding, thereby improving the production efficiency of the self-aligning roller bearing retainer.

[0039] To optimize the above technical solutions, the first groove wall 301 and the second groove wall 302 are elastic walls. Specifically, the first groove wall 301 and the second groove wall 302 are made of a slightly elastic material, so that the first groove wall 301 and the second groove wall 302 can produce sufficient deformation when installing, dismounting or replacing the roller, and at the same time can limit the roller. Such arrangement can make the self-aligning roller bearing retainer have flexibility during operation, disperse the force transmission of the roller, facilitate the installation of the roller, and also limit the roller.

[0040] To optimize the above technical solutions, the support portion protrudes from the outer ring of the first circular ring 100. Specifically, the diameter of the first circular ring 100 is smaller than the diameter of the second circular ring 200, the top of the support portion is connected with the first circular ring 100, the bottom of the support portion is connected with the second circular ring 200, and the support portion protrudes from the outer ring of the first circular ring 100, that is, the connection area of the top of the support portion with the first circular ring 100 is smaller than the connection area of the bottom of the support portion with the second circular ring 200, at this time the support portion is equivalent to a reinforcing rib of the support beam 300, which can significantly improve the load capacity of the self-aligning roller bearing retainer, thereby improving the installation effect of the roller.

[0041] In order to optimize the above technical solutions, the connecting part of the support beam 300 and the first circular ring 100 and / or the second circular ring 200 is arc-shaped. Specifically, the connecting part of the support beam 300 and the first circular ring 100 and / or the second circular ring 200 is arc-shaped transition design, and the arc center is away from the support beam 300. In some embodiments of the present application, the connecting part of the support beam 300 and the first circular ring 100 and / or the second circular ring 200 is arranged with an arc-shaped connecting block. In use, the operator fixes the first circular ring 100 and / or the second circular ring 200 and the support beam 300 together by using the arc-shaped connecting block. Such an arrangement can make the arc-shaped connecting block a reinforcing part for connecting the first circular ring 100 and / or the second circular ring 200 and the support beam 300, thereby improving the stability of the connection between the first circular ring 100 and / or the second circular ring 200 and the support beam 300. In other embodiments of the present application, the support beam 300 and the arc-shaped part are designed in one piece. Such an arrangement can reduce the number of parts of the self-aligning roller bearing cage and improve the stability of the structure. Therefore, the arc-shaped connecting part of the support beam 300 and the first circular ring 100 and / or the second circular ring 200 can enhance the connection strength of the self-aligning roller bearing cage, thereby improving the installation effect of the roller in the self-aligning roller bearing cage.

[0042] In order to optimize the above technical solutions, the first groove wall 301 and / or the second groove wall 302 is provided with an oil guide strip. Specifically, in the use process of the bearing, the self-aligning roller bearing cage and the roller, lubricating oil needs to be used for lubrication. The above oil guide strip is a shallow groove provided in the first groove wall 301 and / or the second groove wall 302, which plays a role in storing and guiding lubricating oil. In use, the self-aligning roller bearing cage and the roller are in a running state, and the lubricating oil is thrown out of the first groove wall 301 and / or the second groove wall 302 along the oil guide strip under the action of centrifugal force, thereby lubricating the self-aligning roller bearing cage and the roller, ensuring the normal work of the bearing. Therefore, by arranging the oil guide strip, the use effect of the self-aligning roller bearing cage and the roller can be improved.

[0043] In order to optimize the above technical scheme, the self-locking part 400 is arranged in the middle of the support beam 300, the first end is connected with the support beam 300, the second end is close to the outer ring of the first circular ring 100, and extends to the middle of the pocket hole 500, and the two self-locking parts 400 on both sides of the pocket hole 500 form an outer locking point. Specifically, the height of the self-locking part 400 is less than or equal to the height of the support beam 300, and the closer the height of the self-locking part 400 to the height of the support beam 300, the greater the contact part of the roller, and the better the limiting effect on the roller. Specifically, the self-locking part 400 is arranged in the middle of the support beam 300, so that the force of the roller is balanced, thereby reducing the friction of the roller during operation, and prolonging the service life of the roller. In use, the roller is arranged in the inside of the pocket hole 500, the second end of the two self-locking parts 400 on both sides of the pocket hole 500 is close to the arrangement, and acts on the roller to form a limiting position. During the operation of the bearing, the roller rotates smoothly in the pocket hole 500 under the limiting of the two self-locking parts 400. Such arrangement can effectively prevent the roller from falling out of the pocket hole 500 of the self-aligning roller bearing retainer, so that the bearing cannot be used normally, and therefore the installation effect of the roller on the self-aligning roller bearing retainer is improved.

[0044] In order to optimize the above technical scheme, the included angle between the first groove wall 301 and the second groove wall 302 is an acute angle, and the first groove wall 301 and the second groove wall 302 on both sides of the pocket hole 500 form an inner locking point. Specifically, the included angle between the first groove wall 301 and the second groove wall 302 is an acute angle, that is, the two groove walls on both sides of the pocket hole 500 are close to each other along the position close to the middle of the pocket hole 500, thereby forming an inner locking point cooperating with the outer locking point. In use, when the roller is installed in the inside of the pocket hole 500, the outer locking point forms a limiting position on the outer side of the roller, the inner locking point forms a limiting position on the inner side of the roller, and the first groove wall 301, the second groove wall 302 and the self-locking part 400 arranged on both sides of the pocket hole 500 jointly act on the roller, thereby realizing self-locking of the roller. Such arrangement can effectively prevent the roller from falling out of the pocket hole 500 of the self-aligning roller bearing retainer, so as to ensure the effective use of the bearing, and therefore the installation effect of the roller on the self-aligning roller bearing retainer is improved.

[0045] In order to optimize the above technical scheme, the top surface of the support part close to the first circular ring 100 is T-shaped. Specifically, the first direction is a ray extending from the first circular ring to the second circular ring, the top surface of the support part is cut downward along the first direction, so that the top surface is T-shaped after cutting. Such arrangement can reduce the rotation resistance of the self-aligning roller bearing retainer under the premise of ensuring the supporting strength of the support beam 300, thereby improving the use effect of the self-aligning roller bearing retainer.

[0046] In order to optimize the above technical scheme, the top and / or bottom of the support beam 300 is arranged with a fitting surface 303 which is fitted with the roller inside the pocket hole 500. Specifically, the number of fitting surfaces 303 connected by one support beam 300 is one or more. Further, in order to make the top and bottom of the roller force uniform, the fitting surfaces 303 are arranged in pairs on the top and bottom of the support beam 300, and further, in order to make the inside and outside of the roller force uniform, the fitting surfaces 303 are arranged in pairs on the side of the support beam 300 close to the inner ring of the first circular ring 100 and the side close to the outer ring of the first circular ring 100. In use, the plurality of fitting surfaces 303 are fitted with the outer surface of the roller, thereby reducing the running noise of the roller and improving the stability of the roller.
