Description

Technical Field

[0001] This utility model belongs to the field of bearing cage technology, and particularly relates to glass fiber reinforced PEEK bearing cages. Background Technology

[0002] Glass fiber reinforced PEEK is a material whose properties are enhanced by adding glass fibers to PEEK. PEEK itself is a high-performance special engineering plastic. By adding glass fibers, the mechanical properties and abrasion resistance of PEEK can be significantly improved, making it more suitable for use in harsh environments such as high temperature and high humidity. Glass fiber reinforced PEEK bearing cages are made of glass fiber reinforced PEEK material.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing glass fiber reinforced PEEK bearing cages:

[0004] 1. The cage cannot continuously provide lubricating grease to the rolling elements, resulting in poor lubrication of the rolling elements. It is inconvenient to set up a grease storage structure on the cage to continuously provide lubricating grease to the rolling elements.

[0005] 2. The cage assembly bolts are prone to loosening due to vibration, which leads to poor cage stability. It is inconvenient to install anti-loosening measures on the cage to prevent rotation and loosening of the cage assembly bolts. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a glass fiber reinforced PEEK bearing cage. This solves the problems of existing cages failing to continuously provide lubricating grease to the rolling elements, resulting in poor lubrication and making it inconvenient to install a grease storage structure on the cage to continuously provide lubricating grease; and the cage assembly bolts being prone to loosening due to vibration, leading to decreased cage stability and making it inconvenient to install anti-loosening measures on the cage to prevent rotation and loosening of the cage assembly bolts.

[0007] The purpose and effect of this utility model of glass fiber reinforced PEEK bearing cage are achieved by the following specific technical means:

[0008] A glass fiber reinforced PEEK bearing cage includes a cage body; the cage body is provided with a lower cage, the top end face of the lower cage is provided with a circular array of ball grooves, threaded blind holes are provided between the ball grooves of the lower cage, oil holes are provided through the ball grooves of the lower cage, and a storage ring groove is provided on the bottom end face of the lower cage. The lower cage is made of glass fiber reinforced PEEK material.

[0009] Furthermore, an anti-loosening annular plate is inserted between the regular hexagonal slots of the assembly locking pin, and a regular hexagonal prism is arranged in a ring array on the bottom end face of the anti-loosening annular plate.

[0010] Furthermore, the upper half of the lower half retainer is locked to the top of the upper half retainer by an assembly locking pin. The bottom end face of the upper half retainer is provided with a circular array of ball grooves. The top end face between the ball grooves of the upper half retainer is provided with a stepped hole that runs vertically through the upper half retainer. The upper half retainer is made of glass fiber reinforced PEEK material.

[0011] Furthermore, an assembly locking pin is installed inside the threaded blind hole of the lower half retainer. A limit pin is provided on the upper part of the assembly locking pin. A regular hexagonal groove is opened on the top end face of the limit pin of the assembly locking pin, and a threaded rod is provided on the bottom end face of the limit pin of the assembly locking pin.

[0012] Furthermore, a closed annular plate is inserted into the storage ring groove of the lower half of the retainer, and an annular insertion protrusion is provided on the top end face of the closed annular plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The lubricating grease is conveniently stored inside the storage ring groove of the lower cage, allowing the lubricating grease to pass through the oil holes of the lower cage to continuously lubricate the rolling elements. This solves the problem that the cage cannot continuously provide lubricating grease to the rolling elements, resulting in poor lubrication of the rolling elements, and that it is inconvenient to set up a grease storage structure on the cage to continuously provide lubricating grease to the rolling elements.

[0015] The regular hexagonal prism of the anti-loosening ring plate is conveniently inserted into the regular hexagonal groove of the assembly locking column. This allows the regular hexagonal prism of the anti-loosening ring plate to prevent rotation and loosening of the assembly locking column. This solves the problem that the assembly bolts of the cage are prone to loosening due to vibration, which leads to poor stability of the cage and makes it inconvenient to add anti-loosening measures to the cage to prevent rotation and loosening of the cage assembly bolts.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a glass fiber reinforced PEEK bearing cage, including a cage body 1; the cage body 1 is provided with a lower half cage 2, which is convenient to assemble with the upper half cage 5 to form a complete bearing cage. The top end face of the lower half cage 2 is provided with a ring array of ball grooves to facilitate the insertion of balls. Threaded blind holes are provided between the ball grooves of the lower half cage 2 to facilitate the assembly of locking pins 4 by threaded installation. The ball grooves of the lower half cage 2 are provided with through-hole oil holes to facilitate the entry of lubricating grease from the storage ring groove into the ball groove to lubricate the rolling elements. The bottom end face of the lower half cage 2 is provided with a storage ring groove to facilitate the storage of lubricating grease. The lower half cage 2 is made of glass fiber reinforced PEEK material to facilitate enhanced mechanical properties and abrasion resistance. A closing annular plate 3 is inserted into the storage ring groove of the lower half cage 2 to facilitate the closure of the storage ring groove of the lower half cage 2. The top end face of the closing annular plate 3 is provided with an annular insertion protrusion to facilitate the locking of the closing annular plate 3 into the storage ring groove of the lower half cage 2 for fixation.

[0026] The lower half of the cage 2 has an assembly locking pin 4 installed inside its threaded blind hole, which facilitates locking and fixing the upper half of the cage 5 and the lower half of the cage 2. A limit pin is provided on the upper part of the assembly locking pin 4 to prevent the upper half of the cage 5 from detaching. A regular hexagonal groove is provided on the top end face of the limit pin of the assembly locking pin 4, allowing for easy rotation and disassembly using tools. The regular hexagonal prism of the anti-loosening ring plate 6 is inserted to prevent rotation and loosening of the assembly locking pin 4. A threaded rod is provided on the bottom end face of the limit pin of the assembly locking pin 4, which is screwed into the threaded blind hole of the lower half of the cage 2. The upper half of the cage 5 is locked to the top of the lower half of the cage 2 via the assembly locking pin 4, facilitating the assembly of the lower half of the cage 2 and the upper half of the cage 5 to form a complete bearing cage. The upper half retainer 5 has a ring array of ball grooves on its bottom end face to facilitate the insertion and rotation of the balls. The top end face between the ball grooves of the upper half retainer 5 has stepped holes that run vertically through it to facilitate the insertion and concealment of the assembly locking pin 4. The upper half retainer 5 is made of glass fiber reinforced PEEK material to enhance its mechanical properties and abrasion resistance. An anti-loosening ring plate 6 is inserted between the regular hexagonal slots of the assembly locking pin 4 to prevent rotation and loosening of the assembly locking pin 4, and to detect whether the assembly locking pin 4 is locked in place. If the assembly locking pin 4 is not locked in place, the anti-loosening ring plate 6 cannot be inserted and installed. The bottom end face of the anti-loosening ring plate 6 has a ring array of regular hexagonal prisms to facilitate insertion into the regular hexagonal slots of the assembly locking pin 4.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In this invention, lubricating grease is pre-stored inside the storage ring groove of the lower half-cage 2, and sealed and leak-proof by a closed annular plate 3 inserted into the storage ring groove of the lower half-cage 2. When the bearing is running, centrifugal force causes the grease to continuously seep into the ball groove through the oil holes of the lower half-cage 2, thereby forming a self-lubricating supply to the rolling elements. At the same time, the friction-resistant properties of the glass fiber reinforced PEEK material can reduce lubrication consumption. Combined with the storage ring groove design of the lower half-cage 2, long-term lubrication is achieved, solving the problem that the cage cannot continuously provide lubricating grease to the rolling elements, resulting in poor lubrication effect of the rolling elements. Meanwhile, the regular hexagonal prism of the anti-loosening annular plate 6 is inserted into the regular hexagonal groove of the assembly locking pin 4, thereby preventing the assembly locking pin 4 from rotating loose through geometric interference. The anti-loosening annular plate 6 also has an assembly detection function, detecting whether the assembly locking pin 4 is locked in place. If the assembly locking pin 4 is not locked in place, the anti-loosening annular plate 6 cannot be inserted for installation, thereby ensuring assembly reliability and solving the problem that the assembly bolts of the cage are prone to loosening due to vibration, resulting in poor stability of the cage.

[0029] Example 2: Unlike Example 1, the bottom end face of the lower half retainer 2 can also be set as a frosted surface, thereby increasing the friction between the bottom end face of the lower half retainer 2 and the closed annular plate 3, and preventing the closed annular plate 3 from rotating.

[0030] Example 3: The difference from Example 1 is that the bottom end face of the assembly locking pin 4 can also be set as a frosted surface, thereby increasing the friction between the bottom end face of the assembly locking pin 4 and the lower half retainer 2, and preventing the assembly locking pin 4 from rotating and loosening.
