Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, specifically a high-strength bearing plastic cage. Background Technology

[0002] A bearing plastic cage is a structural component used to support and separate rolling elements. It is usually made of engineering plastics such as nylon and polytetrafluoroethylene. Its main function is to reduce friction and collision between rolling elements and ensure smooth operation of the bearing. Compared with metal cages, plastic materials have advantages such as light weight, corrosion resistance, low noise, and low cost. They are especially suitable for use in high humidity or energy-saving scenarios. With the continuous upgrading of industrial equipment and the increasing complexity of application scenarios, the performance requirements for cages are also getting higher and higher. At present, traditional cages still have some shortcomings in structural design.

[0003] For example, application number CN202321760182.3 describes a utility model belonging to the technical field of plastic cage equipment, specifically a wheel hub bearing plastic cage. This cage includes an arc-shaped plastic cage, with multiple arc-shaped plastic cages forming a circle. The arc-shaped plastic cage has ball grooves, and an installation assembly is provided between two adjacent arc-shaped plastic cages. The installation assembly includes a locking block, which is fixedly connected to one of the arc-shaped plastic cages. The other arc-shaped plastic cage has a slot on its opposite side, which engages with the locking block. This utility model utilizes arc-shaped plastic cages. If the cage is burned or broken, only the damaged arc-shaped plastic cage needs to be removed and replaced with a new one, eliminating the need to replace the entire cage, thus saving resources and costs. Furthermore, disassembly is much easier than with annular cages, as the arc-shaped plastic cage can be pulled apart simply by pulling it apart.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of needing to replace the cage when it is damaged by bearing friction to avoid affecting the bearing, replacing it for minor damage is wasteful, as discarding the entire cage due to a single point of damage is too costly. Furthermore, the strength and rigidity of the cage connection are relatively weak during use. Under high-speed operation or heavy load conditions, the connection may deform or even break, affecting the bearing's service life and operational stability. Additionally, the cage cannot effectively dissipate the heat generated during bearing operation, leading to excessively high bearing temperatures, which accelerates lubricant deterioration and affects the normal operation of the bearing. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-strength bearing plastic cage that has the advantage of auxiliary fixation and heat dissipation. This solves the problems that the strength and rigidity of the cage connection are relatively weak, and the connection may deform or even break under high-speed operation or heavy load conditions, thereby affecting the service life and operational stability of the bearing. In addition, the cage cannot effectively dissipate the heat generated during the operation of the bearing, resulting in excessively high bearing temperature, which accelerates the deterioration of the lubricant and affects the normal operation of the bearing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength bearing plastic cage, comprising a mounting ring, an arc-shaped plastic cage, ball receiving grooves, and mounting components. The arc-shaped plastic cage is fixedly connected to the inner side of the mounting ring, and four arc-shaped plastic cages are provided. The ball receiving grooves are opened on the outer side of the arc-shaped plastic cages, and each arc-shaped plastic cage has four ball receiving grooves. The mounting components are arranged between the arc-shaped plastic cages, and a support mechanism is fixedly connected between the ball receiving grooves. A heat dissipation component is provided on the outer side of the mounting ring.

[0007] In a preferred embodiment of this invention, the support mechanism includes a connecting arm and a reinforcing rib. The connecting arm is fixedly connected between two ball bearing receiving grooves, and the reinforcing rib is fixedly connected to the outside of the connecting arm. The reinforcing rib is in the shape of an "X".

[0008] In a preferred embodiment of this invention, the heat dissipation component includes heat dissipation holes and a mounting ring. The heat dissipation holes are located on the outer side of the mounting ring and are elongated and evenly distributed in a ring. The mounting ring is fixedly connected to the outer side of the heat dissipation holes.

[0009] As a preferred embodiment of this utility model, the top and bottom of the mounting ring are provided with annular openings, and a cover is movably connected to the inner side of the annular opening. The annular opening and the cover are fixedly connected by a snap fastener.

[0010] As a preferred embodiment of the present invention, a lubrication groove is provided on the inner side of the annular opening, the lubrication groove is connected to both sides of the inner side of the ball receiving groove, and the interior of the lubrication groove is filled with solid lubricant.

[0011] As a preferred embodiment of this invention, a rubber sealing ring is provided on the inner side of the annular opening, and the rubber sealing ring is fitted onto the bottom of the cap.

[0012] As a preferred embodiment of this invention, a circular hole is provided on the inner side of the heat dissipation hole, and the circular hole is connected to the lubrication groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a support mechanism and a heat dissipation component, enhances the structural strength of the plastic cage through the support mechanism, while the heat dissipation component increases the heat dissipation area of ​​the plastic cage, accelerating heat dissipation and preventing bearing damage due to overheating. It solves the problems of relatively weak strength and rigidity at the cage connection, which can deform or even break under high-speed operation or heavy load conditions, thus affecting the service life and operational stability of the bearing. Furthermore, the cage cannot effectively dissipate the heat generated during bearing operation, leading to excessively high bearing temperature, which accelerates lubricant deterioration and affects the normal operation of the bearing. This utility model has the advantage of auxiliary fixed heat dissipation.

[0015] 2. By setting up a support mechanism, this utility model improves the structural strength and rigidity of the arc-shaped plastic cage by connecting the arm and reinforcing rib. The "X"-shaped design of the reinforcing rib can prevent the connecting arm from bending and twisting under stress, thus enabling it to withstand larger radial and axial forces and ensuring the stability of the arc-shaped plastic cage during operation. Furthermore, by setting up a heat dissipation component, the heat dissipation holes increase the heat dissipation area on the outside of the mounting ring. The mounting ring can improve the structural strength at the heat dissipation holes, thereby helping to quickly dissipate the heat generated during bearing operation.

[0016] 3. This utility model, by setting an annular opening and a cover, allows for convenient inspection and maintenance of the internal structure of the annular plastic cage. The annular opening and cover fit tightly against the outer surface of the arc-shaped plastic cage without occupying extra space, making it suitable for more compact installation environments and applications with high space requirements. Furthermore, by setting a lubrication groove and solid lubricant, the solid lubricant filled in the lubrication groove can be continuously released during bearing operation, ensuring lubrication between the balls and the cage, thereby reducing friction and wear during operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a high-strength bearing plastic cage, including a mounting ring 1, an arc-shaped plastic cage 2, ball receiving grooves 3, and a mounting assembly 4. The arc-shaped plastic cage 2 is fixedly connected to the inner side of the mounting ring 1, and there are four arc-shaped plastic cages 2. The ball receiving grooves 3 are opened on the outer side of the arc-shaped plastic cages 2, and each arc-shaped plastic cage 2 has four ball receiving grooves 3. The mounting assembly 4 is arranged between the arc-shaped plastic cages 2, and a support mechanism 5 is fixedly connected between the ball receiving grooves 3. A heat dissipation assembly 6 is arranged on the outer side of the mounting ring 1.

[0023] refer to Figure 2 The support mechanism 5 includes a connecting arm 51 and a reinforcing rib 52. The connecting arm 51 is fixedly connected between two ball bearing receiving grooves 3, and the reinforcing rib 52 is fixedly connected to the outside of the connecting arm 51. The reinforcing rib 52 is in the shape of an "X".

[0024] As a technical optimization of this utility model, by setting up a support mechanism 5, the connecting arm 51 and the reinforcing rib 52 improve the structural strength and rigidity of the arc-shaped plastic cage 2. The "X"-shaped design of the reinforcing rib 52 can prevent the connecting arm 51 from bending and twisting under force, so that it can withstand larger radial and axial forces and ensure the stability of the arc-shaped plastic cage 2 during operation.

[0025] refer to Figure 2 The heat dissipation component 6 includes heat dissipation holes 61 and mounting ring 62. The heat dissipation holes 61 are opened on the outside of the mounting ring 1. The heat dissipation holes 61 are elongated and distributed in a ring at equal intervals. The mounting ring 62 is fixedly connected to the outside of the heat dissipation holes 61.

[0026] As a technical optimization of this utility model, by setting the heat dissipation component 6, the heat dissipation hole 61 increases the heat dissipation area on the outside of the mounting ring 1, and the mounting ring 62 can improve the structural strength at the heat dissipation hole 61, thereby helping it to quickly dissipate the heat generated during the operation of the bearing.

[0027] refer to Figure 3 The top and bottom of the mounting ring 1 are provided with annular openings 7, and a cover 8 is movably connected to the inside of the annular opening 7. The annular opening 7 and the cover 8 are fixedly connected by a snap fastener.

[0028] As a technical optimization of this utility model, by setting an annular opening 7 and a cover 8, the annular opening 7 and the cover 8 can facilitate the inspection and maintenance of the internal structure of the annular plastic retainer, and are tightly fitted to the outer surface of the arc-shaped plastic retainer 2 without occupying extra space, so that it can adapt to a more compact installation environment and is suitable for application scenarios with high space requirements.

[0029] refer to Figure 3 A lubrication groove 9 is provided on the inner side of the annular opening 7. The lubrication groove 9 is connected to both sides of the inner side of the ball receiving groove 3. The interior of the lubrication groove 9 is filled with solid lubricant 10.

[0030] As a technical optimization of this utility model, by setting a lubrication groove 9 and a solid lubricant 10, the solid lubricant 10 filled in the lubrication groove 9 can be continuously released during the operation of the bearing, ensuring lubrication between the balls and the cage, thereby reducing friction and wear during operation.

[0031] refer to Figure 3 A rubber sealing ring 11 is provided on the inner side of the annular opening 7, and the rubber sealing ring 11 is fitted on the bottom of the cover 8.

[0032] As a technical optimization of this utility model, by setting a rubber sealing ring 11, the rubber sealing ring 11 effectively prevents the intrusion of external impurities and moisture, and protects the lubricant and the cleanliness of the bearing interior.

[0033] refer to Figure 2 A circular hole 12 is provided on the inner side of the heat dissipation hole 61, and the circular hole 12 is connected to the lubrication groove 9.

[0034] As a technical optimization of this utility model, by setting a circular hole 12, the lubricant can flow between the heat dissipation hole 61 and the lubrication groove 9. The air flow through the heat dissipation hole 61 carries away more heat, preventing the bearing from overheating, thereby further improving the lubrication effect and heat dissipation efficiency.

[0035] The working principle and usage process of this utility model are as follows: In use, the arc-shaped plastic retainer 2 is first fixed to the corresponding position on the bearing using the mounting ring 1. Then, multiple arc-shaped plastic retainers 2 are connected into a complete circular retainer using the mounting assembly 4. At this time, the connecting arm 51 and reinforcing rib 52 enhance the structural strength and rigidity of the retainer, enabling it to withstand larger radial and axial forces. After the retainer is installed, the heat dissipation hole 61 increases the heat dissipation area on the outside of the mounting ring 1, while the mounting ring 62 improves the structural strength at the heat dissipation hole 61, helping to quickly dissipate the heat generated during bearing operation. Simultaneously, the annular opening 7 and the cover 8... Users can easily inspect and maintain the internal structure of the cage. The cover 8 fits tightly against the outer surface of the arc-shaped plastic cage 2 without taking up extra space. During bearing operation, the solid lubricant 10 in the lubrication groove 9 will be continuously released to ensure lubrication between the balls and the cage, reducing friction and wear. The sealing ring prevents the intrusion of external impurities and moisture, protecting the lubricant and keeping the bearing clean. In addition, the round hole 12 on the inner side of the heat dissipation hole 61 promotes the flow of lubricant between the heat dissipation hole 61 and the lubrication groove 9. The air flow through the heat dissipation hole 61 carries away more heat, preventing the bearing from overheating, thus achieving the advantage of auxiliary fixed heat dissipation.

[0036] In summary, this high-strength bearing plastic cage, through the inclusion of a support mechanism 5 and a heat dissipation component 6, enhances the structural strength of the plastic cage. The support mechanism 5 strengthens the cage, while the heat dissipation component 6 increases the heat dissipation area, accelerating heat dissipation and preventing bearing damage due to overheating. This addresses the problem of relatively weak strength and rigidity at the cage connection, which can lead to deformation or even breakage under high-speed operation or heavy load conditions, affecting bearing life and operational stability. Furthermore, the cage's inability to effectively dissipate heat generated during bearing operation results in excessively high bearing temperatures, accelerating lubricant deterioration and impacting normal bearing operation.
