A radial gap exists between the bearing guide ring and the bearing retainer; the gas collector is arranged on the axial outer end surface of the bearing guide ring, and the gas collector is provided with a gas containing groove, which is suitable for collecting gas during the rotation of the bearing; the bearing guide ring is provided with a gas guide hole connecting the radial gap and the gas containing groove, so that the collected gas enters the radial gap along the gas guide hole;

[0004] However, the above-mentioned bearing assembly needs to be regularly supplied with lubricating oil due to long-term high-pressure wear during operation, which makes it unable to adaptively self-supply lubricating oil according to the working status. The operation is cumbersome and requires maintenance, resulting in low overall working efficiency and certain usage limitations. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of self-lubricating bearing assembly to solve the problem proposed in the above background technology that due to long-term high-pressure wear, the user needs to regularly supply lubricating oil, resulting in the inability to adaptively self-supply lubricating oil according to the working state, thus making the operation cumbersome and requiring maintenance.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new self-lubricating bearing assembly, comprising an inner ring assembly, a bearing ball and an outer ring assembly, wherein the inner end of the inner ring assembly is nested with the bearing ball, and the outer end of the inner ring assembly is nested with the outer ring assembly, and the inner end of the outer ring assembly is butted against the bearing ball;

[0007] The outer end of the outer ring component is provided with a reserved supply through pipe, and the inner side of the outer ring component is provided with a reserved accommodation layer, and the reserved accommodation layer and the reserved supply through pipe are connected to each other, and the inner side of the outer ring component is butt-jointed with a heat conductive butt joint layer, and the positions of the heat conductive butt joint layer and the reserved accommodation layer correspond to each other;

[0008] A supply channel is opened on the inner side of the outer ring component, and the supply channel is connected to the reserved accommodating layer, and the inside of the supply channel is bonded and connected with an adhesive docking layer, the inner side of the outer ring component is bonded and connected with a heated adhesive airbag, and the outer side of the heated adhesive airbag is docked and installed with a docking connector, and the docking connector is arranged inside the outer ring component.

[0009] Furthermore, the outer ring assembly stores lubricating oil by means of a reserved accommodation layer, and the outer ring assembly is butted against the inner ring assembly via bearing balls.

[0010] Furthermore, the thermally conductive docking layer is made of copper, and is distributed at equal angles about the center point of the outer ring assembly, and the position of the thermally conductive docking layer corresponds to that of the reserved accommodation layer, thereby avoiding the disadvantage that the user needs to regularly supply lubricating oil due to long-term high-pressure wear.

[0011] Furthermore, when the heated adhesive airbag is exposed to high temperature, it will expand and push the butt connector outward, and the heated adhesive airbag pushes the butt connector at the outer end to move outward synchronously, which can stably dissipate heat and maintain a constant temperature for the heat carried by the bearing assembly during operation.

[0012] Furthermore, the butt connector is provided with a resisting butt connector and a return spring, and the outer end of the butt connector is fixedly connected to the return spring, and the return spring is fixedly connected to the inner side of the outer ring assembly, while the middle end of the butt connector is fixedly connected to the resisting butt connector, and the resisting butt connector and the outer end of the adhesive butt layer are butt-jointed with each other.

[0013] Furthermore, there are three bonding layers symmetrically arranged about the center point of the supply channel, and the outer side of a single bonding layer is butted against the abutting piece. During the expansion of the heated bonding airbag, the single bonding layers can be driven to break away from the bonding state between each other, and the contact heat can be quickly transferred until the interior of the reserved accommodating layer is combined with lubricating oil for constant temperature heat conversion treatment.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The new self-lubricating bearing assembly is provided with a self-supply structure. As the temperature inside the bearing increases due to high-speed operation, the corresponding heated adhesive airbag will expand, thereby pushing the abutting parts to move outward, driving the single adhesive butt joint layer to break away from the closed state, so that the lubricating oil stored in the reserved accommodation layer is automatically supplied through the open and closed supply channel, avoiding the disadvantage of the user having to regularly supply lubricating oil due to long-term high-pressure wear, and self-supplying the lubricating oil according to the working state, thereby improving the practicality of the device;

[0016] 2. This new self-lubricating bearing assembly is equipped with a constant temperature structure. By storing the lubricating oil inside the reserved accommodation layer, the heat carried by the bearing assembly during operation can be stably dissipated and kept at a constant temperature.

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.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a new self-lubricating bearing assembly, including an inner ring assembly 1, a bearing ball 2, an outer ring assembly 3, a reserved supply pipe 4, a reserved accommodating layer 5, a heat-conducting docking layer 6, a supply channel 7, an adhesive docking layer 8, a heated adhesive airbag 9, a docking connector 10, a resisting docking component 11, and a reset spring 12.

[0025] In this embodiment:

[0026] The inner end of the inner ring component 1 is nested with the bearing ball 2, and the outer end of the inner ring component 1 is nested with the outer ring component 3, and the inner end of the outer ring component 3 is butted against the bearing ball 2;

[0028] A supply channel 7 is opened on the inner side of the outer ring component 3, and the supply channel 7 is connected to the reserved accommodating layer 5, and the inside of the supply channel 7 is bonded and connected with an adhesive docking layer 8, the inner side of the outer ring component 3 is bonded and connected with a heated adhesive airbag 9, and the outer side of the heated adhesive airbag 9 is docked and installed with a docking connector 10, and the docking connector 10 is arranged inside the outer ring component 3.

[0029] The outer ring assembly 3 stores lubricating oil through the reserved accommodation layer 5, and the outer ring assembly 3 is docked with the inner ring assembly 1 through the bearing ball 2. The thermal conductive docking layer 6 is made of copper, and the thermal conductive docking layer 6 is distributed at equal angles about the center point of the outer ring assembly 3, and the positions of the thermal conductive docking layer 6 and the reserved accommodation layer 5 correspond to each other.

[0030] As the bearing heats up at high speed, the corresponding heated adhesive airbag 9 will expand, pushing the abutting piece 11 outward, driving the single adhesive layer on the inside of the supply channel 7 out of the closed state, so that the lubricating oil stored in the reserved accommodating layer 5 is automatically pulled through the open and closed supply channel 7 to open the automatic oil supply, avoiding the disadvantage of the user having to regularly supply lubricating oil due to long-term high-pressure wear.
