[0014] A protective ring pad is provided between the bearing and the core body, which is utilized to reduce the impact of the bearing on the core body and reduce the wear on the core body. When the bearing vibrates back and forth and hits the core body, the protective ring pad is continuously squeezed. When the protective ring pad is squeezed, the multiple groups of buffer grooves inside the protective ring pad are squeezed at the same time. The multiple groups of buffer grooves discharge the internal gas to the outside through the exhaust holes at both ends. The inner diameter of the buffer groove is twice that of the exhaust hole. The gas discharge speed is limited by the aperture and is discharged slowly, which plays a buffering role. The protective ring pad is set to be made of rubber material and is reset by using its own characteristics, which further reduces the wear on the core body, improves the wear resistance and service life of the core body, and solves the problem that the service life of the shaft core is shortened due to long-term wear, thereby increasing the failure rate of the equipment and affecting the normal operation of the equipment.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] The utility model provides a technical solution: an anti-wear bearing shaft core, including a core body 1, a protective layer 2 arranged on the surface of the core body 1 is made of aluminum oxide, and the wear resistance of the core body 1 is increased by utilizing the characteristics of the protective layer 2. At the same time, a maintenance groove 3 opened on the surface of the protective layer 2 is arranged in an S shape on its surface, and lubricating oil can be added through the maintenance groove 3 so that it can be evenly applied to the surface of the protective layer 2 to extend its service life.

[0022] For details, please refer to Figure 1-4A protective ring pad 4 is provided between the bearing 5 and the core body 1. The protective ring pad 4 is used to reduce the impact of the bearing 5 on the core body 1 and reduce the wear on the core body 1. When the bearing 5 vibrates back and forth and hits the core body 1, it continuously squeezes the protective ring pad 4. While the protective ring pad 4 is squeezed, the multiple groups of buffer grooves 6 inside the protective ring pad 4 are squeezed. The multiple groups of buffer grooves 6 discharge the internal gas to the outside through the exhaust holes 7 at both ends. The inner diameter of the buffer groove 6 is twice that of the exhaust hole 7. The gas discharge speed is limited by the aperture and is slowly discharged, which plays a buffering role. The protective ring pad 4 is set to be made of rubber material and is reset by using its own characteristics, which further reduces the wear on the core body 1 and improves the wear resistance and service life of the core body 1.

[0023] Working principle: The protective layer 2 set on the surface of the core 1 is made of aluminum oxide. The characteristics of the protective layer 2 are used to increase the wear resistance of the core 1. At the same time, the maintenance groove 3 opened on the surface of the protective layer 2 is set on its surface in an S shape. Lubricating oil can be added through the maintenance groove 3 so that it can be evenly applied to the surface of the protective layer 2 to extend its service life. A protective ring gasket 4 is set between the bearing 5 and the core 1. The protective ring gasket 4 is used to reduce the impact of the bearing 5 on the core 1 and reduce the wear on the core 1. When the bearing 5 vibrates back and forth and hits the core 1, it continuously squeezes the protective ring gasket 4, and the protective ring gasket 4 is squeezed. At the same time, multiple groups of buffer grooves 6 inside the protective ring pad 4 are squeezed, and the multiple groups of buffer grooves 6 discharge the internal gas to the outside through the exhaust holes 7 at both ends. The inner diameter of the buffer groove 6 is twice that of the exhaust hole 7. The gas discharge speed is limited by the aperture and is slowly discharged, which plays a buffering role. The protective ring pad 4 is set to be made of rubber material and uses its own characteristics to reset, further reducing the wear on the core body 1, improving the wear resistance and service life of the core body 1, and solving the problem that the long-term wear of the shaft core will cause the service life to be shortened, thereby increasing the equipment failure rate and affecting the normal operation of the equipment.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
