Description

Technical Field

[0001] The present application belongs to the technical field of bearing retainers, and in particular relates to a novel sheet metal combination retainer. Background Art

[0002] The combined pillar retainer is composed of two ribs and multiple pillars. The two ends of the pillars are connected by riveting, and the two surfaces of the pillars are designed to be curved surfaces. The production of the pillars involves multiple complex processes such as drawing and stamping notches. These processes not only require high-precision equipment and molds, but each step requires precise control to ensure the quality and precision of the final product. Therefore, a longer processing time is required, which increases the processing cost. Moreover, since the pillars require thicker materials to withstand the processing stress of riveting and curved surfaces, this directly leads to an increase in raw material costs. Since the pillars are made of thicker materials and some materials are cut off or wasted during the processing process, the overall material utilization rate is low, which does not meet the requirements of modern manufacturing for resource conservation and sustainable development. It can be seen that the existing technology needs to be further improved and enhanced. Utility Model Content

[0003] The utility model provides a novel sheet metal combination retainer to solve the problems faced by the combined pillar retainer in the production process, such as high cost, complex production, low material utilization rate, high maintenance and replacement costs.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A novel sheet assembly retainer includes an annular end cover assembly and a plurality of thin sheet units;

[0006] The annular end cover assembly is evenly distributed with positioning and mounting holes corresponding to the number of sheet units; the sheet unit includes a main body and mounting columns at both ends, the mounting columns cooperate with the positioning and mounting holes, and one side of the main body is provided with an arc-shaped contact surface matching the contour of the rolling body. The arc-shaped contact surfaces of the two sheet units are arranged back to back and their respective mounting columns are installed in the adjacent positioning and mounting holes of the annular end cover, forming a double-sheet pillar structure, and pockets for accommodating the rolling bodies are formed between adjacent double-sheet pillar structures to reduce material usage and reduce production costs.

[0007] The sheet-type combined retainer of this application features a thin sheet-like design for the sheet elements, significantly reducing material usage and effectively conserving resources. In the event of damage, only the damaged sheet element can be replaced, achieving both economical and efficient operation. Each sheet element consists of a main body and mounting posts at both ends. The shape of the mounting posts precisely matches the positioning holes in the annular end caps, greatly simplifying the installation process and ensuring quick and accurate assembly. The curved contact surface on one side of the main body is carefully designed to perfectly conform to the contours of the rolling elements, ensuring smooth and stable movement of the rolling elements within the pockets. During the manufacturing process, the thin sheet-like sheet elements can be produced using efficient processing methods such as stamping and cutting. Compared to traditional complex processes such as drawing and punching, these modern processing techniques are not only simpler to operate but also more easily control processing accuracy. Furthermore, the reduced material thickness significantly shortens the processing cycle. The overall structure adheres to the lightweight design concept, effectively reducing the weight of the retainer and further reducing the overall mass of the rolling bearing, which has positive implications for improving the operating efficiency and energy utilization of the equipment. Although the sheet unit is designed to be relatively light and thin, the adoption of a double sheet pillar structure provides solid support for the overall structure, effectively ensuring the strength and rigidity of the structure and meeting the use requirements of high-performance bearings.

[0008] In a preferred implementation, an oil-passing gap is provided between the two sheet units of the double-sheet pillar structure.

[0009] The oil gap between the double-blade struts provides a smooth passage for the lubricant, preventing it from directly impacting the blade elements and reducing the impact force on them. The gap also accommodates and guides the lubricant within the cage, ensuring a consistent lubricant film between the rolling elements and the curved contact surfaces. At high-speed bearing operation, friction between the rolling elements and the blade elements generates heat. The oil in the gap acts not only as a lubricant but also as a heat transfer medium. This absorbs and removes heat from the blade elements, significantly extending the bearing's service life and reducing maintenance costs.

[0010] In a preferred implementation, the oil gap gradually becomes smaller in the direction toward the center of the circle.

[0011] The gradual design of the oil gap helps optimize lubricant distribution. During bearing operation, lubricant needs to be evenly distributed between the rolling elements and the web elements. The gradual reduction of the oil gap directs the lubricant to the center of the rollers, rather than directly through the gaps, ensuring that these critical areas are fully lubricated.

[0012] In a preferred implementation, the sheet unit is a thin sheet-shaped arc-shaped plate.

[0013] In a preferred implementation, a reinforcing rib is provided between the two sheet units of the double-sheet pillar structure to abut against the two.

[0014] The reinforcement ribs, as the connecting elements between the two sheet elements, significantly increase the overall rigidity of the support structure. This increased rigidity helps the cage maintain a stable shape and position during bearing operation, reducing deformation caused by vibration or impact.

[0015] In a preferred implementation, the reinforcing ribs of the two sheet units of the double-sheet pillar structure are staggered / oppositely arranged.

[0016] In a preferred implementation, the reinforcing ribs are integrally formed with the sheet unit.

[0017] In a preferred implementation, the reinforcing rib is detachably connected to the sheet unit.

[0018] In a preferred implementation, a coating is provided on the surface of the arc-shaped contact surface to improve smoothness and wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] In the description of the present invention, it should be understood that the terms "center," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "axial," "radial," "circumferential," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the present invention, unless otherwise expressly specified or limited, a first feature being "up" or "down" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0028] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] In this utility model, terms such as "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0030] The present invention will be described below with reference to the accompanying drawings.

[0031] The specific plans adopted are:

[0032] like Figure 1-4 As shown, the utility model provides a novel sheet assembly retainer, comprising an annular end cover assembly 1 and a plurality of thin sheet units;

[0033] The annular end cover assembly is evenly distributed with positioning and mounting holes 10 corresponding to the number of sheet units; the sheet unit 2 includes a main body and mounting columns at both ends, the mounting columns 20 cooperate with the positioning and mounting holes, and one side of the main body 21 is provided with an arcuate contact surface 210 that matches the contour of the rolling body. The arcuate contact surfaces of the two sheet units are arranged back to back and their respective mounting columns are installed in the adjacent positioning and mounting holes of the annular end cover, forming a double-sheet pillar structure, and pockets for accommodating the rolling bodies are formed between adjacent double-sheet pillar structures to reduce material usage and reduce production costs.

[0034] In the above structure, the sheet element adopts a thin sheet design, which greatly reduces the amount of material used. Each unit includes a main body and mounting posts at both ends. The shape of the mounting posts matches the positioning and mounting holes of the annular end cap, facilitating quick and accurate installation. The arc-shaped contact surface on one side of the main body is designed according to the contour of the rolling element, ensuring that the rolling element runs smoothly in the pocket. The thin sheet element can be processed using efficient methods such as stamping and cutting. These methods are simpler than traditional complex processes such as drawing and punching, and the precision is easy to control. At the same time, due to the reduced material thickness, the processing time is also shortened accordingly. The overall structure adopts a lightweight design, which not only reduces the weight of the cage, but also reduces the overall weight of the rolling bearing, which is beneficial to improving the operating efficiency and energy utilization of the equipment. Although the sheet element is relatively thin, through reasonable structural design and precise installation, it can ensure the stable operation of the rolling element in the pocket. The overall strength and rigidity are guaranteed due to the support of the double sheet pillar structure.

[0035] As a preferred embodiment of the present application, there is an oil gap 3 between the two sheet units of the double-sheet pillar structure. During the operation of the bearing, the lubricating oil will flow with the rotation of the rolling body. The oil gap between the double-sheet pillar structure provides a smooth channel for the lubricating oil, avoiding the lubricating oil from directly colliding with the sheet unit, reducing the impact force of the lubricating oil on the sheet unit, and the oil gap can accommodate and guide the lubricating oil to circulate inside the cage, ensuring that there is always enough lubricating oil film between the rolling element and the arc-shaped contact surface. When the bearing runs at high speed, the rolling element and the sheet unit will generate heat due to contact friction. The lubricating oil in the oil gap not only acts as a lubricant, but also acts as a heat transfer medium. The lubricating oil can absorb and take away the heat from the sheet unit, which can significantly extend the service life of the bearing and reduce maintenance costs.

[0036] Furthermore, the oil gap 3 gradually decreases in spacing toward the center. This non-uniform spacing design is based on the principle that the spacing of the pockets should gradually increase toward the center to ensure that the rollers do not escape from the pockets due to centrifugal forces during operation. Because the spacing of the pockets gradually increases toward the center, while the oil gap gradually decreases, this design helps provide additional stability when the rollers are subjected to centrifugal forces. The reduction in the oil gap limits excessive radial movement of the rollers, thereby reducing the risk of the rollers escaping from the pockets due to centrifugal forces.

[0037] The gradual design of the oil gap helps optimize lubricant distribution. During bearing operation, lubricant needs to be evenly distributed between the rolling elements and the web elements. The gradual reduction of the oil gap directs the lubricant to the center of the rollers, rather than directly through the gaps, ensuring that these critical areas are fully lubricated.

[0038] As a preferred embodiment of the present application, the sheet unit is a thin sheet-like curved plate. The thin sheet-like curved plate design significantly reduces the weight of the sheet unit, thereby achieving lightweight retaining frame. Although the sheet unit is thin sheet-like, its curved design can enhance the strength and rigidity of the structure to a certain extent. The curved plate can better adapt to the contour of the rolling element, provide stable support, and disperse stress when subjected to load, preventing damage caused by local stress concentration. The thin sheet-like curved plate design makes the manufacturing and assembly process of the sheet unit simpler and more efficient. This design can adopt efficient processing methods such as stamping and cutting to quickly produce high-precision sheet units.

[0039] As a preferred embodiment of this application, a reinforcing rib 4 is provided between the two sheet units of the dual-sheet support structure, abutting the two. As a connecting member between the two sheet units, the reinforcing rib significantly increases the overall rigidity of the support structure. This increased rigidity helps the cage maintain a stable shape and position during bearing operation, reducing deformation caused by vibration or impact. When subjected to external loads, the reinforcing rib effectively disperses stress, preventing stress concentration in localized areas of the sheet units. This helps extend the cage's service life and prevents fatigue damage caused by stress concentration.

[0040] Furthermore, the reinforcing ribs 4 can be integrally formed with the sheet unit or assembled using a simple connection process, such as plugging them into each other, so as to reduce production costs and improve production efficiency.

[0041] The design of the reinforcing ribs can also facilitate the assembly of the retaining frame. For example, in the detachable connection method, the two sheet units can be connected by the reinforcing ribs first, and then assembled to the end ring. This can ensure that the two sheet units maintain the correct relative position and angle during the assembly process, thereby improving assembly accuracy and efficiency.

[0042] As a preferred embodiment of this embodiment, the reinforcing ribs of the two sheet units of the dual-sheet pillar structure are staggered or arranged relative to each other. This staggered or relative arrangement of the reinforcing ribs can effectively disperse stress concentration within the sheet units when subjected to stress, resulting in a more uniform stress distribution. This helps reduce damage caused by excessive local stress and improves the stability and durability of the overall structure.

[0043] As a preferred embodiment of the present application, a coating is provided on the surface of the arcuate contact surface to improve smoothness and wear resistance.

[0044] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.

[0045] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and such variations or substitutions are intended to fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
