Description

Oval keeper convenient to equipment

Technical Field

The utility model relates to a bearing keeps ware technical field, especially relates to an ellipse that is convenient for assemble keeps ware.

Background

Bearing cages (also called bearing cages) refer to bearing parts that partially enclose all or part of the rolling bodies and move with them, to isolate the rolling bodies and generally also to guide and retain them within the bearing. At present, a retainer with a circular ball pocket is provided, so that the play of balls is enlarged, and a gap between the retainer and a steel ball is large, so that lubricating grease can enter the retainer. However, since the pockets of the oval retainer are semi-oval cut along the major axis, the length of the pockets occupying the circumference of the retainer is large, that is, the space between the pockets is small, and thus the oval retainer cannot be adapted to the conventional assembly method of the assembled bearing, such as providing connection holes between the pockets, and the like, because the connection strength of the retainer at the space between the pockets is further reduced, the oval retainer is easily broken.

Disclosure of Invention

To the unable problem that is suitable for current bearing equipment mode of above-mentioned oval holder, the utility model provides a do not need to set up the oval holder of the equipment of being convenient for of connection structure in the interval department of ball pocket.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an ellipse is kept ware convenient to equipment, includes the annular of two relative settings keeps the ware subassembly, keeps the ware subassembly to be provided with a plurality of ball pockets and connecting plate, and ball pocket and connecting plate are evenly interval distribution on keeping the ware subassembly, two ball pockets one-to-one that keep the ware subassembly, connecting plate one-to-one, and two ball pockets of mutual correspondence enclose into the ellipse, and the connecting plate compresses tightly together through the mounting. The connecting plates of the two ball pockets are tightly pressed together through the fixing piece, a connecting structure is not required to be arranged at the joint between the ball pockets, and the structural strength of the oval retainer is ensured while the connection is ensured.

Preferably, the mounting is U type structure, and the mounting is including two relative clamp plates that set up, and the both ends of limiting plate are connected respectively to two same ends of clamp plate, two the clamp plate is two connecting plate laminating that correspond respectively. The pressing plates are pressed on two sides of the two corresponding connecting plates through the limiting plates.

Preferably, the fixing piece and the two corresponding connecting plates are in interference fit. The fitting strength between the holder components is improved, and separation or falling-off thereof is prevented.

Preferably, the ball pocket and the connecting plate are integrally formed. The overall strength of the holder assembly is ensured.

Preferably, some of the connection plates are provided with positioning slots adapted to the limiting plates, the positioning slots being evenly distributed on the holder assembly. The limiting plate is prevented from protruding to affect the installation on the bearing, and meanwhile, the matching efficiency of the retainer assembly is improved.

Preferably, the pocket is shaped as a semi-ellipse cut along the major axis, the length of the major axis being 1.01 to 2 times the length of the minor axis.

The utility model has the advantages that two opposite retainer components are connected together through the fixing piece, a connecting structure is not needed to be arranged on the retainer components, the processing steps of the retainer components are reduced, and the connecting strength of the ball pocket connecting part of the retainer components is improved; the retaining groove provided by the retainer assembly prevents the fixing member from affecting the retainer and bearing fit.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of protection of this patent.

As shown in fig. 1-3, an oval retainer convenient for assembly comprises two annular retainer components which are oppositely arranged, wherein ten groups of ball pockets 1 and ten groups of connecting plates 2 are arranged on the retainer components, the ball pockets 1 and the connecting plates 2 are uniformly distributed on the retainer components at intervals, the ball pockets 1 of the two retainer components are in one-to-one correspondence, and the connecting plates 2 of the two retainer components are in one-to-one correspondence; the ball pocket 1 is a semi-elliptical shape cut along the major axis, and the length of the major axis is 1.01 to 2 times, preferably 1.1 times, the length of the minor axis. Two corresponding ball pockets 1 enclose into the ellipse, can increase the play amount of ball in ball pocket 1, are convenient for simultaneously add lubricating oil, nevertheless because the shape of ball pocket 1 has occupied the most length of keeping the ware subassembly on the circumference, lead to the distance of the connecting plate 2 between the ball pocket 1 to shorten, if set up connection structure can appear stress concentration's problem, lead to keeping the ware in use fracture, consequently adopt mounting 6 to compress tightly the connection with two ware subassemblies. Mounting 6 is the U type, including limiting plate 5, two mutual disposition's clamp plate 4 are connected respectively at the both ends of limiting plate 5, and limiting plate 5 is located two clamp plate 4 with one side, two perpendicular clamp plates 4 of limiting plate 5 simultaneously, two clamp plates 4 laminate with two corresponding connecting plates 2 respectively, are interference fit between two corresponding connecting plates 2 and the mounting 6, improve the firm degree of connection. Be provided with the constant head tank 3 with the adaptation of limiting plate 5 on the connecting plate 2, constant head tank 3 sets up on the interior circumference of holder subassembly, and constant head tank 3 evenly distributed on the holder subassembly simultaneously, has a connecting plate 2 to set up constant head tank 3 in one side that is close to the circle in the holder at every other a set of promptly, has five groups of constant head tank 3 altogether, and constant head tank 3 can improve the packaging efficiency with the cooperation of limiting plate 5, prevents simultaneously that mounting 6 from influencing the cooperation of holder and bearing.

The utility model discloses a principle does, through interference fit's mounting 6 and corresponding connecting plate 2, keeps the ware subassembly to compress tightly two and connects, keeps the connecting plate 2 of ware to keep the ware for ordinary under the shorter condition of connecting plate 2, has guaranteed the structural strength that oval keeps the ware, has improved the packaging efficiency, has also reduced the processing degree of difficulty that oval keeps the ware simultaneously.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
