[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 2 , an embodiment provided by the utility model: a rolling deep groove ball non-standard bearing, including an outer fixing ring 1, which is the main structural part of the bearing and is responsible for providing support and fixing. Its material selection is usually high-strength steel or alloy material to ensure stability and wear resistance under high load and high-speed operation conditions. The inner part of the outer fixing ring 1 is fixedly connected with a rubber plug into the oil hole 2, which is used to close the oil hole to prevent external contaminants from entering the oil storage chamber 3, while maintaining the sealing of the internal lubricating oil. The rubber material has good elasticity and corrosion resistance, and can withstand the temperature and pressure changes when the bearing is working, ensuring that it will not deform after long-term use. The inner part of the outer fixing ring 1 is fixedly connected with an oil storage chamber 3, which is a space for storing lubricating oil. A reasonably designed oil storage chamber 3 can effectively extend the lubrication cycle of the bearing and reduce frictional heat. The shape and capacity of the oil storage chamber 3 are optimized to ensure the fluidity and lubrication effect of the oil during the operation of the bearing. Its internal surface is smooth to reduce the flow resistance of the oil. The bottom of the oil storage chamber 3 is fixedly connected with an oil outlet 4,

[0033] Located at the bottom of the oil storage chamber 3, it is responsible for releasing the lubricating oil to the working area of ​​the bearing through gravity or pressure. The design of the oil outlet hole 4 must ensure that the oil can be evenly distributed to avoid wear caused by insufficient oil. The diameter and position of the oil outlet hole 4 have been precisely calculated to meet the lubrication requirements under different working conditions. The outside of the oil outlet hole 4 is fixedly connected with an outer circular arc groove 5, which is a structure provided on the outside of the oil outlet hole 4 for guiding and dispersing the lubricating oil released from the oil outlet hole 4. Its arc-shaped design can effectively reduce the resistance to oil flow, ensure that the oil is evenly distributed to various parts of the bearing, and enhance the lubrication effect. The inside of the outer fixing ring 1 is fixedly connected with an annular groove 12, which is provided inside the outer fixing ring 1 for fixing and supporting the buckle 13. The design of the groove ensures that the buckle 13 can be firmly locked and is convenient for disassembly and replacement. The processing precision of the annular groove 12 is high to prevent the buckle 13 from loosening or falling off during operation.

[0034] The annular groove 12 is internally fixedly connected to a buckle 13, which is a component used to fix the dust cover 14. Its design ensures that the dust cover 14 can maintain its stability during the operation of the bearing. The material of the buckle 13 is generally selected from wear-resistant and corrosion-resistant metal materials to ensure that it is not easily damaged during long-term use. The shape and structure of the buckle 13 are optimized for quick installation and removal. The dust cover 14 is fixedly connected to the outside of the buckle 13 to protect the interior of the bearing from the intrusion of dust and other external contaminants, thereby extending the service life of the bearing. The material selected for the dust cover 14 has good temperature resistance and corrosion resistance, which can adapt to the working environment of the bearing. Its design should ensure sealing with the outer fixing ring 1 to prevent lubricating oil leakage. The dust cover 14 is externally fixedly connected to the cover ring 15, which is an external fixing component of the dust cover 14 and further enhances the sealing and firmness of the dust cover 14. The design of the cover ring 15 generally takes into account the needs of easy installation and removal to ensure convenience during maintenance and replacement. The material and structure of the cover ring 15 should match the dust cover 14 to provide additional protection and support.

[0035] Reference Figures 3 and 4, the inner rotation of the outer fixed ring 1 is connected with the steel ball 6, which is the key moving part of the bearing, responsible for rolling between the outer fixed ring 1 and the inner fixed ring 10, reducing friction and improving movement efficiency, the outer fixed connection of the steel ball 6 is connected with the retaining frame 7, the function of which is to fix the steel ball 6 in the appropriate position and maintain the spacing between them to ensure uniform load distribution. The retaining frame 7 is usually made of lightweight materials such as plastic or metal, and is designed to have a certain degree of elasticity to adapt to the dynamic changes of the bearing during operation. The shape and structure of the retaining frame 7 are optimized to reduce friction and wear. The outer fixed connection of the retaining frame 7 is connected with a fixing column 8, which is used to connect the retaining frame 7 and other structures to provide additional support and stability. Its design ensures that when the bearing is working, it can effectively withstand the pressure from the retaining frame 7 and the steel ball 6 and maintain the structural integrity of the entire assembly. The bottom rotation connection of the steel ball 6 is connected with an inner arc groove 9, which is connected to the bottom rotation of the steel ball 6.

[0036] It plays the role of guiding and supporting the steel ball 6. Its arc-shaped design can effectively disperse the load, reduce local pressure, and provide a smooth path for the rolling of the steel ball 6. The surface of the inner arc groove 9 has been finely processed to ensure good contact with the steel ball 6 and reduce the friction coefficient. The bottom of the inner arc groove 9 is rotatably connected to the inner fixed ring 10, which is another important component of the bearing and is responsible for cooperating with the steel ball 6 and forming the inner ring of the bearing. The design of the inner fixed ring 10 ensures that it can withstand the pressure from the steel ball 6 during operation and maintain the overall stability of the bearing. The outside of the inner fixed ring 10 is fixedly connected to a sealing ring 11, which is used on the outside of the inner fixed ring 10 and is responsible for preventing lubricating oil leakage and external contaminants from entering the inside of the bearing. The material of the sealing ring 11 is usually oil-resistant and temperature-resistant rubber or polymer, which can adapt to the needs of bearings in different working environments. The design of the sealing ring 11 ensures a close fit with the inner fixed ring 10, forming an effective sealing effect and extending the service life of the bearing.

[0037] Reference Figures 5 and 6 The outer retaining ring 1 has an outer arc groove 5 formed inside, which is a groove of a specific shape and is designed to support and guide the movement of the steel ball 6. Its arc-shaped structure can effectively disperse the load, reduce local stress concentration, and provide a smooth channel for the rolling of the steel ball 6. The steel ball 6 is rotatably connected to the inside of the outer arc groove 5. The inner retaining ring 10 has an inner arc groove 9 formed outside, which is a groove on the inner retaining ring 10 and is specially designed to support and guide the movement of the steel ball 6. Its arc-shaped design can effectively disperse the load, reduce friction, and thus improve the rotation efficiency of the bearing. The steel ball 6 is rotatably connected to the inside of the inner arc groove 9. The outer retaining ring 1 has an annular groove 12 formed inside, which is located inside the outer retaining ring 1 and is used to fix and support the buckle 13. The buckle 13 is slidably connected to the inside of the annular groove 12. Its design ensures that the buckle 13 can be firmly locked during the operation of the bearing to prevent loosening or falling off.

[0038] Working principle: When the bearing starts to run, the outer fixing ring 1 provides stable support for the entire structure, ensuring normal operation under high load and high speed conditions. The internal rubber plug oil hole 2 closes the oil hole, effectively preventing external contaminants from entering the oil storage chamber 3, while maintaining the sealing of the lubricating oil to prevent oil leakage. The oil storage chamber 3 serves as a storage space for lubricating oil, and its design has been optimized to extend the lubrication cycle and reduce friction heat. The smooth surface inside the oil storage chamber 3 promotes oil flow, reduces flow resistance, and thus significantly improves the lubrication effect. The lubricating oil is released through the oil outlet hole 4 at the bottom. The design of the oil outlet hole 4 ensures that the oil can be evenly distributed to the working area of ​​the bearing to prevent wear caused by insufficient oil. The diameter and position of the oil outlet hole 4 have been precisely calculated to meet the lubrication requirements under different working conditions. The outer arc groove 5 outside the oil outlet hole 4 guides and disperses the lubricating oil released from the oil outlet hole 4. Its arc design effectively reduces the resistance to oil flow, ensuring that the oil is evenly distributed to various parts of the bearing, further improving the lubrication effect.

[0039] Inside the bearing, an annular groove 12 is used to secure and support the clip 13, ensuring that the clip 13 is securely locked for easy removal and replacement. The clip 13 is used to secure the dust cover 14. Its design ensures the stability of the dust cover 14 during bearing operation, effectively preventing the intrusion of dust and other contaminants. The material of the dust cover 14 has excellent temperature and corrosion resistance, adapted to the operating environment of the bearing, and forms an excellent seal with the outer retaining ring 1. Finally, the cover ring 15 on the outside of the dust cover 14 further enhances the sealing and firmness of the dust cover 14, ensuring convenience during maintenance and replacement. Through the coordinated operation of this series of structures, the non-standard rolling deep groove ball bearing can provide excellent lubrication under various operating conditions.
