Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, specifically a highly stable tapered roller bearing cage. Background Technology

[0002] In modern mechanical transmission systems, tapered roller bearings are widely used in various industrial equipment and machinery due to their unique structure and performance characteristics. With the continuous advancement of industrial technology, the increase in equipment operating speed, and the increasing complexity of load conditions, the performance requirements for tapered roller bearings are becoming more and more stringent. Among them, the cage, as one of the key components of tapered roller bearings, directly affects the overall operating stability, service life, and reliability of the bearing.

[0003] According to the authorized announcement number CN218844869U, a highly stable tapered roller bearing cage is disclosed, belonging to the technical field of bearing cages. It includes an upper support ring and a lower support ring, with multiple heat dissipation isolation components between them. Each heat dissipation isolation component has a fixing structure, and the fixing structure is connected to the upper support ring, lower support ring, and heat dissipation isolation components via threaded connections to threaded grooves. Multiple threaded grooves are located above the lower support ring. This highly stable tapered roller bearing cage, by setting the fixing structure and threaded grooves, and by using a hexagonal head to rotate the screw, allows the screw to disengage from the threaded grooves, thus separating the upper support ring, heat dissipation isolation components, and lower support ring. This allows for replacement of the damaged components, avoiding the waste associated with replacing the entire tapered roller bearing cage.

[0004] However, the above-mentioned device still has shortcomings. Although a replaceable heat dissipation isolation component is used to replace the damaged cage, the heat dissipation isolation component adopts a double-layer set structure, which has certain problems in terms of service life and stability. Its support structure is difficult to provide sufficient rigidity and stability, which causes the roller to deviate and wobble during operation. This not only aggravates the wear between the roller and the raceway and reduces the service life of the bearing, but may also cause instability in equipment operation, generate abnormal noise and vibration, and affect the normal operation of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a tapered roller bearing cage with high stability to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable tapered roller bearing cage, comprising a lower cage plate, a side cage body, and an upper cage plate, wherein the side cage body is mounted on the top of the lower cage plate, and the upper cage plate is mounted on the top of the side cage body.

[0007] The side frame includes a long frame, an extended side plate, a mounting block, and a reinforcing heat dissipation plate. The extended side plate is fixedly connected to the outer sides of the upper and lower ends of the long frame. The mounting block is fixedly connected to the upper and lower ends of the long frame. The reinforcing heat dissipation plate is evenly installed inside the long frame. The mounting block, in conjunction with the extended side plate, ensures the stable installation of the long frame between the lower and upper frame plates. Adding a reinforcing heat dissipation plate inside the long frame ensures the structural stability of the side frame. At the same time, heat is transferred to the reinforcing heat dissipation plate through thermal conduction, achieving effective heat dissipation.

[0008] Preferably, the upper shelf includes a circular frame, a hollow reinforcing block, a fastening bolt, and a sealing cap. The hollow reinforcing block is fixedly connected to the inside of the circular frame. The fastening bolt passes through the circular frame and connects to the side frame. The sealing cap is snapped onto the top of the circular frame. By setting a hollow reinforcing block inside the circular frame, the structural strength of the circular frame can be increased, while the weight of the circular frame can be reduced. The lightweight structure can reduce wear.

[0009] Preferably, the fastening bolt includes a rotating block, a buffer pad, and a screw. The buffer pad is located at the bottom of the rotating block, and the screw is located at the bottom of the buffer pad. The rotating block drives the screw to rotate, so that the screw is threadedly connected to the mounting block, and the side frame is installed between the lower frame plate and the upper frame plate. Then, the buffer pad is used for reinforcement and noise reduction to ensure stable connection.

[0010] Preferably, the lower and upper frame plates have the same structure, with the lower frame plate being larger than the upper frame plate, making the device structure conical for installing roller bearings.

[0011] Preferably, the long frame is made of aluminum alloy, which has good thermal conductivity, high strength and corrosion resistance, and can effectively prevent corrosion in high temperature and humid environments, thus extending its service life. The reinforced heat dissipation plate is made of copper, which utilizes copper's good heat dissipation properties for heat exchange and heat dissipation for the high-speed rotating bearing.

[0012] Preferably, the hollow reinforcing block adopts a W-shaped design, which has good sturdiness and support, strengthens the support strength, and ensures the connection stability between the upper and lower frame plates, thereby improving the operational stability of the cage under complex working conditions.

[0013] Preferably, the buffer pad is made of polyurethane, which can quickly absorb energy when impacted and convert vibration into its own deformation energy, thus achieving excellent shock absorption. In addition, the surface of polyurethane has good friction properties and can provide sufficient friction to prevent slippage.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This highly stable tapered roller bearing cage, through the use of mounting blocks and extended side plates, ensures the secure installation of the long frame between the lower and upper frame plates. The addition of a reinforced heat dissipation plate inside the long frame ensures the structural stability of the side frame, while utilizing thermal conduction to transfer heat to the reinforced heat dissipation plate for effective heat dissipation.

[0016] 2. This highly stable tapered roller bearing cage, by incorporating hollow reinforcing blocks within the circular cage, increases the structural strength of the circular cage while reducing its weight. This lightweight structure reduces wear. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a tapered roller bearing cage with high stability, comprising a lower frame plate 1, a side frame 2 and an upper frame plate 3, wherein the side frame 2 is installed on the top of the lower frame plate 1 and the upper frame plate 3 is installed on the top of the side frame 2.

[0024] The side frame 2 includes a long frame 201, an extended side plate 202, a mounting block 203, and a reinforced heat dissipation plate 204. The extended side plate 202 is fixedly connected to the outer sides of the upper and lower ends of the long frame 201. The mounting block 203 is fixedly connected to the upper and lower ends inside the long frame 201. The reinforced heat dissipation plate 204 is evenly installed inside the long frame 201. The mounting block 203, in conjunction with the extended side plate 202, ensures the stable installation of the long frame 201 between the lower frame plate 1 and the upper frame plate 3. The addition of the reinforced heat dissipation plate 204 inside the long frame 201 ensures the structural stability of the side frame 2. At the same time, heat is transferred to the reinforced heat dissipation plate 204 through heat conduction, achieving effective heat dissipation. The long frame 201 is made of aluminum alloy, which has good thermal conductivity, high strength, and corrosion resistance, effectively preventing corrosion in high temperature and humid environments and extending its service life. The reinforced heat dissipation plate 204 is made of copper, utilizing the good heat dissipation properties of copper for heat exchange and heat dissipation of the high-speed rotating bearing.

[0025] The upper frame 3 includes a circular frame 301, a hollow reinforcing block 302, a fastening bolt 303, and a sealing cover 304. The hollow reinforcing block 302 is fixedly connected to the inside of the circular frame 301. The fastening bolt 303 passes through the circular frame 301 and connects to the side frame 2. The sealing cover 304 is snapped onto the top of the circular frame 301. By setting the hollow reinforcing block 302 inside the circular frame 301, the hollow reinforcing block 302 adopts a W-shaped design, which has good sturdiness and support, and strengthens the support strength, the connection stability between the upper frame 3 and the lower frame 1 can be well guaranteed, improving the operational stability of the cage under complex working conditions. It can increase the structural strength of the circular frame 301, while reducing the weight of the circular frame 301, resulting in a lightweight structure. To reduce wear, the fastening bolt 303 includes a rotating block 310, a buffer pad 311, and a screw 312. The buffer pad 311 is located at the bottom of the rotating block 310, and the screw 312 is located at the bottom of the buffer pad 311. The buffer pad 311 is made of polyurethane, which can quickly absorb energy when impacted and convert vibration into its own deformation energy, thus achieving excellent shock absorption. Moreover, the surface of polyurethane has good frictional properties, which can provide sufficient friction to prevent slippage. The rotating block 310 drives the screw 312 to rotate, so that the screw 312 is threadedly connected to the mounting block 203, and the side frame 2 is installed between the lower frame plate 1 and the upper frame plate 3. Then, the buffer pad 311 is used for reinforcement and noise reduction to ensure stable connection.

[0026] The lower frame plate 1 and the upper frame plate 3 have the same structure. The size of the lower frame plate 1 is larger than that of the upper frame plate 3, making the device structure conical, which is used for the installation of roller bearings.

[0027] When in use, place the upper frame plate 3 in a suitable installation position, then connect and fix the bottom of the side frame 2 to the lower frame plate 1, and connect and fix the top of the side frame 2 to the upper frame plate 3. After installing the sealing cover 304, the cage can be installed. During the operation of the tapered roller bearing, the heat generated by the rotation of the tapered roller is transferred to the reinforced heat sink 204. Due to the spacing of the heat sink fins, the heat dissipation area and heat dissipation distance are increased, and the heat can be quickly dissipated to the surrounding environment, effectively reducing the temperature of the cage. When one of the side frames 2 of the cage is damaged, the damaged side frame 2 can be replaced separately to restore the normal use of the cage.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
