They can be used on parts that bear radial loads or combined loads of radial and axial loads, and can also be used on parts that bear axial loads.

[0003] The existing deep groove ball bearings with cages have sliding friction between the rolling elements and the cages, while the full-ball deep groove ball bearings have two adjacent balls loaded at the same time during operation. When the two balls come into contact, the friction resistance between the balls and the grooves increases sharply, resulting in sliding friction. Sliding friction can affect the normal operation of the bearings and may cause problems such as increased vibration and noise, thereby affecting the overall performance and stability of the machinery and equipment.

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figures 1 to 3 A rolling deep groove ball bearing comprises an inner ring 1 and an outer ring 2. The outer wall of the outer ring 2 is provided with a plurality of openings corresponding to each other, and a liquid storage tank 3 is fixedly connected in the corresponding openings. Lubricating liquid is placed on the inner wall of the liquid storage tank 3. The inner wall of the outer ring 2 is fixedly connected with a plurality of retaining frames 4 corresponding to each other. A rolling body 5 is rollingly connected to the inner wall of each retaining frame 4. A temperature sensor 6 is installed on the inner wall of the retaining frame 4. A liquid outlet pipe 7 is connected to the outer wall of the liquid storage tank 3. The lower end of the liquid outlet pipe 7 is connected to the retaining frame 4. A temperature sensor 6 is installed in each retaining frame 4, which can monitor the working temperature of the bearing in real time. By monitoring the temperature change, it can be timely discovered whether the bearing has problems such as overheating, so that corresponding measures can be automatically taken to protect the bearing from damage.

[0025] An electromagnetic valve 8 is installed on the outer wall of the liquid outlet pipe 7 (the electromagnetic valve 8 is a normally closed electromagnetic valve, and the normally closed electromagnetic valve is a prior art, which will not be described in detail here). The electromagnetic valve 8 is electrically connected to the temperature sensor 6. When the temperature in the retaining frame 4 rises sharply, the temperature sensor 6 will drive the electromagnetic valve 8 to open, so that the lubricating liquid in the liquid storage tank 3 flows into the outer surface of the rolling element 5 in the retaining frame 4 through the liquid outlet pipe 7. The lubricating liquid will be replenished to the friction part in time, reducing friction loss and extending the service life of the bearing.

[0026] An opening is provided on the outer wall of the inner ring 1, and a collecting frame 9 is slidably connected to the inner wall corresponding to the opening, a sponge board 10 is fixedly connected to the inner wall of the collecting frame 9, and a lifting handle 11 is fixedly connected to the outer wall of the collecting frame 9. The sponge board 10 can absorb and fix the lubricating oil therein, thereby avoiding the overflow and waste of the lubricating oil, effectively reducing the use of the lubricating oil, and reducing the lubrication cost. The lifting handle 11 can make the collecting frame 9 easier to open, thereby improving the work efficiency of the operator.

[0027] The outer wall of the inner ring 1 is provided with a plurality of corresponding penetration grooves 12. Part of the outflowing lubricating fluid will flow through the penetration port into the sponge board 10 in the collecting frame 9 so that it can be reused. This recycling can effectively reduce the waste of lubricating fluid and improve the lubrication efficiency.

[0028] The outer wall of each rolling element 5 contacts the outer surface of the inner ring 1, which can effectively transmit the force from the external load, help to reduce the stress on the mechanical parts, and improve the bearing capacity of the bearing.

[0029] The area of ​​the penetration groove 12 is smaller than the contact area between the rolling element 5 and the outer surface of the inner ring 1 .

[0030] The operating principle of the utility model is described as follows: when in use, the inner ring 1 rotates and then drives the hybrid body to rotate in the cage 4. Due to the friction between the rolling body 5 and the cage 4, the rolling body 5 and the groove slide friction. When the friction reaches a certain degree, the temperature in the cage 4 will rise greatly. Since the temperature sensor 6 is electrically connected to the solenoid valve 8, the temperature sensor 6 will drive the solenoid valve 8 to open, so that the lubricating liquid in the liquid storage tank 3 flows into the outer surface of the rolling body 5 in the cage 4 through the liquid outlet pipe 7. The lubricating liquid will be replenished to the friction part in time, reducing friction loss and extending the service life of the bearing.

[0031] At this time, part of the lubricating liquid will flow to the outer surface of the inner ring 1. Since the outer surface of the inner ring 1 is provided with a penetration groove 12, part of the outflowing lubricating liquid will flow through the penetration port into the sponge board 10 in the collection frame 9 so that it can be reused. This recycling can effectively reduce the waste of lubricating liquid and improve the lubrication efficiency.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
