[0002] Robot bearings are key components designed specifically for industrial robots. They are mainly used in the joints or rotating parts of industrial robots. Common high-end robot bearings include crossed roller bearings (high carbon chromium), deep groove ball bearings (high carbon chromium), and harmonic reducer flexible bearings (bearing steel).

[0003] While existing crossed roller bearings in high-end robots can meet the rotational requirements of rotating parts and joints, and can withstand radial, axial, and overturning loads, they still have the following shortcomings in practical applications:

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, by setting a first auxiliary mechanism, allows a cross roller bearing of one size to be installed with components of various sizes and shapes, thereby expanding the application range of impact-resistant and wear-resistant high-end robot bearings and improving their efficiency. When it is necessary to install and connect the cross roller bearing with a component on a high-end robot, the two outer rings can be installed together with the component on the high-end robot by first using the second mounting hole, the prepared bolts, and the prepared nuts. Then, the main ring, auxiliary ring, limiting groove, the prepared bolts, and the prepared nuts can be used to fix the main ring, auxiliary ring, and inner ring together. Finally, the main ring can be installed together with the component on the high-end robot by using the main ring, the second auxiliary hole, the prepared bolts, and the prepared nuts.

[0020] 2. When the auxiliary block needs to be installed together with the components on the high-end robot, the present invention first uses the prepared screws, the first rectangular hole, the second rectangular hole, the first cylindrical hole, the rectangular positioning groove and the screw hole reserved on the auxiliary block to fix the auxiliary block together. Then, the components on the high-end robot are passed through the second rectangular hole, and the prepared bolts, nuts and the first auxiliary hole are used to install the auxiliary block together with the components on the high-end robot.

[0021] 3. By setting up an auxiliary mechanism, this invention allows for the individual replacement of any damaged component in the impact-resistant and wear-resistant high-end robot bearing, eliminating the need for a complete replacement. When assembling the bearing, the first roller, the second roller, the first plastic spacer, and the second plastic spacer work together to allow the two outer rings to rotate and connect to the inner ring. When installing the crossed roller bearing to components on the high-end robot, the second mounting hole, the provided bolts, and the provided nuts work together to install the two outer rings to the components. Then, the first mounting hole, the provided bolts, and the provided nuts work together to install the inner ring to the components.

[0022] 4. The present invention, through the provision of a second auxiliary mechanism, allows the heat generated by friction during the rotation of all the first rollers, first plastic spacers, second rollers, and second plastic spacers inside the impact-resistant and wear-resistant high-end robot bearing to be carried away, thereby reducing the impact of heat on the operation of the impact-resistant and wear-resistant high-end robot bearing. When the impact-resistant and wear-resistant high-end robot bearing completes the installation and connection operation with the components on the high-end robot, the prepared inlet pipe, prepared outlet pipe, two round pipes, two annular cavities, two connecting holes, sealing gaskets, and connecting pipes are used to allow the low-temperature cooling water output from the inlet pipe to enter the outlet pipe and then be discharged. In other words, the flowing low-temperature cooling water carries away the heat generated by the first rollers, first plastic spacers, second rollers, and all second plastic spacers during operation, thereby improving the service life of the impact-resistant and wear-resistant high-end robot bearing.

[0038] Example 2: According to Figures 1-8 , Figure 10 and Figure 11As shown, the bearing body 1 is provided with a first auxiliary mechanism 2, which includes a main ring 201 and two sets of limiting grooves 202. An auxiliary ring 205 is installed on the main ring 201. The inner wall of the main ring 201 has multiple rectangular positioning grooves 206. An auxiliary block 207 is provided between the interiors of the multiple rectangular positioning grooves 206.

Multiple first rectangular holes 208 are equidistantly distributed on the front surface of the auxiliary block 207. A second rectangular hole 209 is pre-set on the front surface of the auxiliary block 207. The inner wall of each first rectangular hole 208 has a first cylindrical hole 210. Each positioning end of the main ring 201 is respectively connected to the interior of one set of each limiting groove 202. Each positioning end of the auxiliary ring 205 is respectively connected to the interior of the other set of each limiting groove 202. The auxiliary block 207 is located inside the main ring 201. Each first rectangular hole 208 is connected to each screw hole reserved on the auxiliary block 207. The interior of each first rectangular hole 208 is connected to the interior of each first cylindrical hole 210.

The auxiliary ring 205 is located inside the inner ring 103. Multiple second mounting holes 108 are equidistantly distributed on the front surface of the inner ring 103.

[0039] In this embodiment, when it is necessary to install and connect the crossed roller bearing to a component on the high-end robot, firstly, the second mounting holes 108 on the two outer rings 101, along with the prepared bolts and nuts, are used to install the two outer rings 101 together with the component on the high-end robot. Then, the main ring 201, auxiliary ring 205, limiting groove 202, prepared bolts and nuts are used to fix the main ring 201, auxiliary ring 205, and inner ring 103 together. Next, the main ring 201 is installed to the component on the high-end robot using the main ring 201, second auxiliary hole 204, prepared bolts and nuts. When it is necessary to install and connect the crossed roller bearing to a component on the high-end robot, firstly... Using the second mounting holes 108 on the two semi-outer rings 101, along with the prepared bolts and nuts, the two semi-outer rings 101 are installed together with the components on the high-end robot. Then, the main ring 201, auxiliary ring 205, and inner ring 103 are fixed together. Next, using the prepared screws, the first rectangular hole 208, the second rectangular hole 209, the first cylindrical hole 210, the rectangular positioning groove 206, and the screw holes reserved on the auxiliary block 207, the auxiliary block 207 is fixed together with the main ring 201. After that, the components on the high-end robot are passed through the interior of the second rectangular hole 209. Finally, using the prepared bolts, nuts, and the first auxiliary hole 203, the auxiliary block 207 is installed together with the components on the high-end robot.

[0040] Example 3: According to Figure 1 , Figure 2 and Figures 6-11 As shown, the bearing body 1 includes two outer rings 101, with an inner ring 103 between them. Multiple first rollers 104, multiple first plastic spacers 105, multiple second rollers 106, and multiple second plastic spacers 109 are disposed between the two outer rings 101 and the inner ring 103. The bearing body 1 is equipped with a second auxiliary mechanism 3, which includes two circular tubes 301. Each outer ring 101 has a pre-set annular cavity 302 inside, and each annular cavity 302 has a pre-set connecting hole 303 on its inner wall. One connecting hole 303 is fixedly fitted with a connecting tube 304, and the other connecting... The inner wall of the hole 303 is provided with an annular groove 307. The inside of the annular groove 307 is provided with a sealing gasket 308. The liquid outlet end face of the connecting pipe 304 is in contact with the surface of the sealing gasket 308. The inner wall of each annular cavity 302 is provided with a second cylindrical hole 305. Each round tube 301 is fixedly sleeved inside the second cylindrical hole 305. The top of one half of the outer ring 101 is provided with a circular positioning groove 306. The bottom of the other half of the outer ring 101 is fixed with a positioning block 309. The circular positioning groove 306 is adapted to the positioning block 309. The annular groove 307, the sealing gasket 308 and the connecting pipe 304 are used to connect the two connecting holes 303.

[0041] In this embodiment, when the impact-resistant and wear-resistant high-end robot bearing completes the installation and connection operation with the components on the high-end robot, the two round pipes 301 are first connected to the outlet end of the prepared cooling water inlet pipe and the inlet end of the cooling water outlet pipe, respectively. When the impact-resistant and wear-resistant high-end robot bearing is put into use, all the first rollers 104, all the first plastic spacers 105, all the second rollers 106, and all the second plastic spacers 109 in the impact-resistant and wear-resistant high-end robot bearing rotate simultaneously. At this time, these components will work due to friction. Heat is generated, and then low-temperature cooling water is injected into the circular pipe 301 connected to it through the water inlet pipe. The low-temperature cooling water that enters the circular pipe 301 then enters the annular cavity 302 connected to it. Then, through the cooperation of two connecting holes 303, sealing gasket 308 and connecting pipe 304, it enters the other annular cavity 302. After that, it enters the circular pipe 301 connected to the water outlet pipe and then is discharged. When the low-temperature cooling water flows through the annular cavity 302, the flowing low-temperature cooling water will carry away the heat transferred to the outer half ring 101.

[0042] The overall effect and working principle of the mechanism are as follows:

[0043] During the bearing assembly stage, when the bearing needs to be assembled, first remove one half of the outer ring 101 and the inner ring 103. Then, place both the removed half of the outer ring 101 and the inner ring 103 on a horizontal workbench. Keeping the position of the half of the outer ring 101 unchanged, finely adjust the position of the inner ring 103. Next, place the first first roller 104 between the half of the outer ring 101 and the inner ring 103, then place the first first plastic spacer 105 (the two are in contact), then place the first second roller 106 (the first first plastic spacer 105 is in contact with the first second roller 106), and then place the first second plastic spacer 109 (the second plastic spacer 109 is in contact with the second roller 106). Once the first first roller 104, the first first plastic spacer 105, the first second roller 106, and the first second plastic spacer 109 are complete... After the initial placement, the second first roller 104 is inserted (the second first roller 104 contacts the first second plastic spacer 109). The above steps are then repeated until the last second plastic spacer 109 is inserted and contacts the first first roller 104. Lubricating oil is then applied to all the first rollers 104, all the first plastic spacers 105, all the second rollers 106, and all the second plastic spacers 109. An auxiliary ring 102 is then placed on one of the outer ring halves 101. The other outer ring halves 101 are then removed and placed on one of the outer ring halves 101. Finally, the two outer ring halves 101 are secured together with the prepared bolts and nuts (at this point, the auxiliary ring 102 is positioned between the two outer ring halves 101). This completes the cross roller bearing assembly operation.

[0044] During the installation phase, the first method is as follows: When it is necessary to install and connect the crossed roller bearing to the components on the high-end robot, firstly, use the second mounting holes 108 on the two half outer rings 101, along with the prepared bolts and nuts, to install the two half outer rings 101 together with the components on the high-end robot. Then, use the first mounting holes 107 on the inner ring 103, along with the prepared bolts and nuts, to install the inner ring 103 together with the components on the high-end robot.

[0045] The second method: When it is necessary to install and connect the crossed roller bearing to the components on the high-end robot, first use the second mounting holes 108 on the two half outer rings 101, the prepared bolts and nuts to install the two half outer rings 101 together with the components on the high-end robot. Then, use the main ring 201, auxiliary ring 205, limit groove 202, the prepared bolts and nuts to fix the main ring 201, auxiliary ring 205 and inner ring 103 together. Finally, use the main ring 201, the second auxiliary hole 204, the prepared bolts and nuts to install the main ring 201 together with the components on the high-end robot.

[0046] The third method: When it is necessary to install and connect the crossed roller bearing to the components on the high-end robot, firstly, use the second mounting holes 108 on the two half outer rings 101, the prepared bolts and nuts to install the two half outer rings 101 together with the components on the high-end robot. Then, fix the main ring 201, the auxiliary ring 205 and the inner ring 103 together. Next, use the prepared screws, the first rectangular hole 208, the second rectangular hole 209, the first cylindrical hole 210, the rectangular positioning groove 206 and the screw holes reserved on the auxiliary block 207 to fix the auxiliary block 207 together with the main ring 201. Then, pass the components on the high-end robot through the inside of the second rectangular hole 209. Finally, use the prepared bolts, the prepared nuts and the first auxiliary hole 203 to install the auxiliary block 207 together with the components on the high-end robot.

[0047] During the cooling phase, when the impact-resistant and wear-resistant high-end robot bearing completes the installation and connection operation with the components on the high-end robot, the two round pipes 301 are first connected to the outlet end of the prepared cooling water inlet pipe and the inlet end of the cooling water outlet pipe, respectively. When the impact-resistant and wear-resistant high-end robot bearing is put into use, all the first rollers 104, all the first plastic spacers 105, all the second rollers 106, and all the second plastic spacers 109 in the impact-resistant and wear-resistant high-end robot bearing rotate simultaneously. At this time, these components will generate friction during operation. Heat is generated, and then low-temperature cooling water is injected into the circular pipe 301 connected to it through the water inlet pipe. The low-temperature cooling water that enters the circular pipe 301 then enters the annular cavity 302 connected to it. Then, through the cooperation of two connecting holes 303, sealing gasket 308 and connecting pipe 304, it enters the other annular cavity 302. After that, it enters the circular pipe 301 connected to the water outlet pipe and then is discharged. When the low-temperature cooling water flows through the annular cavity 302, the flowing low-temperature cooling water will carry away the heat transferred to the outer half ring 101.

[0048] All components of the high-end robot bearing are made of impact-resistant and wear-resistant materials (high carbon steel).
