Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, specifically to a deep groove ball bearing cage and a deep groove ball bearing. Background Technology

[0002] The bearing cage is an important component of a bearing. It partially encloses all the rolling elements, isolating them, guiding their rotation, and holding them between the inner and outer rings of the bearing. There are many types and structures of bearing cages. Among them, the deep groove ball bearing cage is the most common type, used in deep groove ball bearings. The rolling elements of deep groove ball bearings are generally spherical.

[0003] Chinese patent CN220060272U discloses a deep groove ball bearing cage. By configuring the first and second cages as a detachable connection structure, workers can quickly replace the damaged steel balls after disassembling the cage, avoiding unnecessary economic losses caused by replacing the entire deep groove bearing. During disassembly, workers can pull the pin to slide the locking hole into the connecting rod under pressure, thus separating it from the locking hole and allowing the connecting rod to be quickly unlocked and pulled out from the mating sleeve. This allows for rapid disassembly of the entire cage, improving the efficiency of steel ball replacement. Four locking holes and two sets of locking rods are provided horizontally and vertically, increasing the locking strength between the first and second cages and preventing separation during use.

[0004] In the above scheme, although the quick-release structure enables the rapid assembly and disassembly of the first and second cages, the cages after assembly can only provide support for the balls, but cannot effectively lubricate them while the balls are rolling. This causes the balls to rub against each other inside the cage for a long time, resulting in wear and other damage.

[0005] Therefore, this utility model provides a deep groove ball bearing cage and a deep groove ball bearing to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a deep groove ball bearing cage and a deep groove ball bearing, so as to solve the problem that the cage after the assembly can only provide support for the balls, but it is difficult to effectively lubricate them when the balls are rolling, which leads to the balls rubbing inside the cage for a long time, resulting in wear and other damage.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A deep groove ball bearing cage includes two splicing frame bodies and a connecting assembly. Each of the two splicing frame bodies has positioning holes arranged in a circumferential array. Each positioning hole has an oil reservoir. The two splicing frame bodies are assembled by the connecting assembly, and the positioning holes and oil reservoirs form a ball placement cavity and a lubricating oil placement cavity.

[0009] Preferably, the cross-section of the oil storage tank is funnel-shaped, and the narrow side of the oil storage tank is located at the connection between the positioning hole and the oil storage tank.

[0010] Preferably, the oil storage tank is provided with an expansion groove, and the wide side of the oil storage tank is located at the connection between the expansion groove and the oil storage tank.

[0011] Preferably, the splicing frame is provided with a collection groove, and the collection groove is connected to the expansion groove.

[0012] Preferably, the connecting component includes a weight-reducing groove, an assembly groove, a connecting rod, and a connecting ring. The weight-reducing groove and the assembly groove are respectively opened on two splicing frames. The assembly groove has a through hole. The connecting rod is installed on one splicing frame, and the connecting ring is set on the other splicing frame. One end of the connecting rod passes through the through hole and is threaded into the connecting ring.

[0013] A deep groove ball bearing includes a deep groove ball bearing cage, an outer ring, an inner ring, and balls. The balls are installed in a ball placement cavity. An assembly cavity is provided between the outer ring and the inner ring, and the deep groove ball bearing cage is installed in the assembly cavity.

[0014] Preferably, both the outer ring and the inner ring of the bearing are provided with ball grooves that match the ball bearing components.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By opening oil reservoirs on the positioning holes of both splicing frames, and the connection between the oil reservoir and the positioning hole is a narrow surface and the whole is flared, after the cage is assembled, the lubricating oil placement cavity formed by the oil reservoir can store lubricating oil. When the ball rolls in the positioning hole, the oil reservoir can continuously apply lubricating oil to the ball through the connecting narrow surface, avoiding long-term dry friction of the ball, fundamentally reducing the wear and damage of the ball caused by friction, and extending the service life of the ball and the entire bearing.

[0017] 2. By opening an expansion groove in the oil reservoir, with the expansion groove having the same diameter as the wide opening of the oil reservoir, the lubricating oil storage capacity of the oil reservoir can be significantly increased, providing a sufficient oil source for ball lubrication. If lubricating oil accidentally falls onto the surface of the cage, it can flow into the expansion groove through the collection groove, and then be circulated back into the oil reservoir for ball lubrication. This avoids lubricating oil waste, ensures the continuity of the lubrication process, and improves the economic efficiency of bearing use. Attached Figure Description
