Description

Technical Field

[0001] This utility model belongs to the field of bearing cage technology, and more specifically, it relates to a bearing cage with self-lubricating function. Background Technology

[0002] The bearing cage is a crucial component of a bearing. Its core function is to partially or completely enclose the rolling elements and move with them. It plays a vital role in isolating the rolling elements and often guides them, ensuring their stable position within the bearing. By maintaining a suitable distance between the rolling elements, it effectively prevents them from contacting each other, thereby reducing friction and promoting even load distribution. While bearing cages typically possess lubrication capabilities, in practice, most existing bearing cages only lubricate the internal balls, lacking the crucial self-lubricating function. This limits their effectiveness and application range, necessitating further improvement and refinement. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a bearing cage with a self-lubricating function, thus solving the problem of existing equipment lacking self-lubricating capabilities.

[0004] This utility model discloses a bearing cage with self-lubricating function, which is achieved by the following specific technical means:

[0005] A bearing cage with self-lubricating function includes: an inner bearing ring; a ball groove is formed in the middle of the outer side of the inner bearing ring; an outer bearing ring is arranged around the outer side of the inner bearing ring; a ball groove is also formed in the middle of the inner side of the outer bearing ring; balls are placed in the ball grooves; and a bearing cage is provided in the gap between the inner and outer bearing rings. The bearing cage can be further divided into an upper retaining ring and a lower retaining ring, and retaining rings are provided in the middle of the lower side of the upper retaining ring and the upper side of the lower retaining ring.

[0006] Furthermore, mounting grooves are provided on the outer sides of both the upper and lower sides of the inner ring of the bearing, and mounting grooves are also provided on the inner sides of both the upper and lower sides of the outer ring of the bearing. For the upper retaining ring and the lower retaining ring, mounting rings are provided at their corresponding positions, and these mounting rings are placed inside the mounting grooves.

[0007] Furthermore, four sets of through holes are provided at the protruding positions of the upper and lower retaining rings. A fixing screw sleeve is provided in the through hole of the upper retaining ring, and a fixing screw is provided in the through hole of the lower retaining ring. The upper end of the fixing screw can extend into the lower end of the fixing screw sleeve and be connected to it by threads.

[0008] Furthermore, both the upper retaining ring and the lower retaining ring are provided with an oil reservoir inside. An oil inlet is provided on the upper side of the upper retaining ring and the front side of the lower side of the lower retaining ring, and a threaded cap is provided in the oil inlet.

[0009] Furthermore, an oil outlet is provided at the middle position of the arc-shaped surface of the retaining ring, and an oil outlet is also provided on the side of the retaining ring.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By setting an installation ring and fixing the bearing, the structure of this utility model helps to stabilize the bearing cage and prevent it from falling off during use, thereby preventing adverse effects on the normal use and operation of the bearing.

[0012] 2. This utility model has oil outlets in the middle of the arc-shaped surface of the retaining ring and on both the side. In this way, the oil reservoir can not only lubricate the balls inside the bearing, but also lubricate itself. Attached Figure Description

[0031] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0032] Example:

[0033] As attached Figure 1 To be continued Figure 5 As shown:

[0034] This utility model provides a bearing cage with self-lubricating function, including: an inner bearing ring 1; a ball groove is formed in the middle of the outer side of the inner bearing ring 1; an outer bearing ring 2 is arranged around the outer side of the inner bearing ring 1; a ball groove is also formed in the middle of the inner side of the outer bearing ring 2; balls 11 are placed in the ball groove; and a bearing cage is provided in the gap between the inner bearing ring 1 and the outer bearing ring 2. The bearing cage can be further divided into an upper retaining ring 4 and a lower retaining ring 5, and a retaining ring 7 is provided in the middle of the lower side of the upper retaining ring 4 and the upper side of the lower retaining ring 5.

[0035] Among them, such as Figures 2 to 5 As shown, mounting grooves 101 are provided on the outer sides of both the upper and lower sides of the inner ring 1 of the bearing, and mounting grooves 101 are also provided on the inner sides of both the upper and lower sides of the outer ring 2 of the bearing. For the upper retaining ring 4 and the lower retaining ring 5, mounting rings 12 are provided at their corresponding positions, and the mounting rings 12 are placed inside the mounting grooves 101. Four sets of through holes 10 are provided at the protruding positions of the retaining rings 7 of the upper and lower retaining rings. A fixing sleeve 3 is provided in the through hole 10 of the upper retaining ring 4, and a fixing screw 301 is provided in the through hole 10 of the lower retaining ring 5. The upper end of the fixing screw 301 can extend into the lower end of the fixing sleeve 3 and be connected to it by threads. This structural design helps to stabilize the bearing cage and prevent it from falling off during use, thereby preventing adverse effects on the normal use and operation of the bearing.
