[0024] See also Figures 1 to 4 The embodiment of the utility model provides a high-strength and durable reducer gear shaft bearing, including a bearing connecting ring 1 and a bearing body 2. The top of the bearing connecting ring 1 is provided with a bearing body 2. The outer wall surface of the bearing body 2 is evenly provided with a plurality of groups of external mounting grooves 3. A group of oblique rotation rods 4 are respectively provided in the external mounting grooves 3. An anti-leakage sealing cover 5 is provided at the outer end of the top of the bearing body 2. A heat dissipation slot 6 is provided on the inner side of the anti-leakage sealing cover 5. A bearing top cover 7 is provided on the inner side of the heat dissipation slot 6. A bearing inner ring 8 is provided on the inner wall of the bearing body 2. A plurality of setting grooves are evenly provided on the bearing inner ring 8. A group of rolling rods 9 are respectively provided in the setting grooves. The top of the bearing connecting ring 1 fixes the installation of the bearing body 2, so that the bearing connecting ring 1 and the bearing body 2 form the basic supporting components of the reducer gear shaft bearing. The outer wall of the bearing body 2 fixes the installation of the oblique rotation rod 4 by setting a plurality of groups of external mounting grooves 3. When the bearing and the reducer gear contact each other, the contact end of the reducer gear and the oblique rotation rod 4 Relative support and relative angular displacement are generated between them, so as to realize the stable setting of the bearing and the reducer gear. An anti-leakage sealing cover 5 is arranged on the top of the bearing body 2 to realize the sealing setting of the external lubrication groove 26, so as to ensure the lubrication of the oblique rotating rod 4 component and prevent the lubricating oil from overflowing and affecting the installation environment and sanitation of the bearing component. A heat dissipation slot 6 is arranged on the top of the heat dissipation frame 21 to facilitate the heat absorbed by the heat dissipation frame 21 to be discharged, so that the bearing body 2 has good thermal conductivity and heat dissipation performance, so as to prevent the heat generated by the high-speed rotation of the bearing from having an adverse effect on its use. A bearing top cover 7 is arranged to fix the bearing body 2 to install the bearing top device and the bearing inner ring 8, so as to ensure the stable setting of the bearing body 2 component. The bearing inner ring 8 is limited to the installation of the rolling rod 9 by multiple sets of grooves. The rotation limit between the bearing and the reducer gear connecting shaft can effectively prolong the service life of the bearing and improve the control stability between the gear shaft bearing and the reducer gear connecting shaft.

[0025] See also Figure 2 and Figure 3, an external lubrication groove 26 is provided near the outer end of the bearing body 2 close to the inclined rotating rod 4. Inside the external lubrication groove 26, a heat dissipation frame 21 is provided. Inside the cavity of the heat dissipation frame 21, there are two layers of damping frames up and down. The upper damping frame includes a first damping rubber ring 22. Second damping rubber rings 23 are staggered on the first damping rubber ring 22. A group of shock-absorbing and buffering rubber columns 24 are respectively arranged between the first damping rubber ring 22 and the second damping rubber ring 23. Inside the heat dissipation frame 21, a rolling rod installation skeleton 25 is provided. An internal lubrication groove 27 is provided at the outer edge of the outer end of the rolling rod installation skeleton 25. The outer end of the external lubrication groove 26 is connected to the installation position of the inclined rotating rod 4, and can transmit the lubricating oil liquid to the connection part of the inclined rotating rod 4, so that the inclined rotating rod 4 can establish contact with the connection device at the outer end of the reducer gear, reduce the rotation restriction, and ensure the normal operation of the reducer. Inside the bearing body 2, the heat dissipation frame 21 is set up to support its internal channels, and the heat generated during the rotation of the rolling rod 9 is absorbed by the heat dissipation frame 21 and dissipated through the heat dissipation slot 6. The heat dissipation frame 21 is the main component for supporting the connection and rotation of the reducer gear. Its main body is set as a support structure by the heat dissipation frame 21, and two damping frames are arranged inside the heat dissipation frame 21 to reduce the negative impact of the bearing rotation force on the main structure of the bearing body 2. The rolling rod installation skeleton 25 is set up to stably install the rolling rod 9 and support the fixed setting of the inner ring 8 of the bearing. The internal lubrication groove 27 is set to provide lubricating oil for the rolling rod 9 to ensure the free rotation of the rolling rod 9.

[0026] The upper damping frame is staggered by the first damping rubber ring 22 and the second damping rubber ring 23 to achieve the circumferential buffering of the force on the bearing body 2, reduce the negative impact on the bearing itself caused by the vibration generated during the rotation of the reducer rotating shaft, and set the shock-absorbing and buffering rubber columns 24 to enhance the buffering effect of the upper damping frame and reduce the negative impact on the upper damping frame caused by the vibration impact force.

[0027] The heat dissipation slot 6 and the anti-permeation seal cover 5 are independently arranged, and there is no communication between the heat dissipation slot 6 and the anti-permeation seal cover 5. While the anti-permeation seal cover 5 ensures the sealing of the external lubrication groove 26, the heat dissipation slot 6 can quickly dissipate the heat on the heat dissipation frame 21.

[0028] Refer to Figure 4, at the outer end of the bottom of the bearing connection ring 1, there is an installation seat 12. On the inner and outer sides of the installation seat 12, there are respectively limit rings. Inside the installation seat 12, there is a bottom heat dissipation port 13.

The outer end of the bottom of the bearing connection ring 1 is assembled with the connection end of the reducer gear through the installation seat 12 and the limit rings, so that the bearing connection ring 1 is stably installed with the bearing seat hole. The sound-absorbing cotton layer 15 can absorb the noise generated during the rotation of the reducer gear and convert the noise into heat and dissipate it. The bottom heat dissipation port 13 is set to discharge the heat converted by the sound-absorbing cotton layer 15 and the heat generated at the bottom connection end during the rotation of the reducer gear, reducing the negative impact of gear rotation on the bearing. The dust-proof film 14 is set to prevent external dust from entering the bottom heat dissipation port 13. The bottom contact end 16 establishes the contact between the bearing connection ring 1 and the connection rotating shaft of the reducer gear, generates friction with the connection rotating shaft, and establishes the contact and rotation control of the connection rotating shaft of the reducer gear on the bearing connection ring 1.

[0029] The outer wall of the bearing body 2 is designed to be inclined inward from bottom to top according to the outer contour of the reducer gear, to cope with the connection of the contact end of the bearing body 2 with the reducer gear with a specific shape, so that it is not easy to produce looseness and breakage between the contact end of the reducer gear and the bearing body 2, and the service life of the bearing body 2 is prolonged.

[0030] At the connection between the top of the built-in lubrication groove 27 and the bearing top cover 7, there is a lubricating oil port. At the top of the lubricating oil port, there is a lubricating port protection cover 10. By opening the lubricating oil protection cover 10, lubricating oil can be added into the lubricating oil port. Its lubricating function can reduce the rotation restriction of the bearing body 2 on the inclined rotating rod 4 and the rolling rod 9, so that both the inclined rotating rod 4 and the rolling rod 9 have high rotation performance, and the connection control between the gear and the bearing can be ensured.

[0031] Below the upper damping frame, there is a lower damping frame. The lower damping frame assembly includes two groups of damping rubber rings arranged in a staggered manner. The shock-absorbing buffer rubber columns 24 are respectively inserted into the lower damping frame. The upper damping frame 1 and the lower damping frame are arranged oppositely to support the force buffering inside the heat dissipation frame 21. With the setting of the shock-absorbing buffer rubber columns 24, the buffer protection of the inner cavity of the heat dissipation frame 21 is enhanced.

[0032] At the position corresponding to the inclined rotating rod 4 on the bearing connection ring 1, there are respectively rotating rod setting bases 11. At the outer end of the rotating rod setting base 11, there is a limit ring. The upper end panel of the bearing connection ring 1 uses the rotating rod setting base 11 to establish a fixed connection with the bottom of the inclined rotating rod 4, and the installation and limit control of the inclined rotating rod 4 are realized in cooperation with the limit ring.

[0033] The bottom heat dissipation port 13 includes two sets of heat dissipation grooves, and a heat conduction fin is provided between the two sets of heat dissipation grooves, which increases the heat conduction performance and heat dissipation space of the heat dissipation component and improves the heat dissipation efficiency.

[0034] There are a number of through grooves between the internal lubrication groove 27 and the external lubrication groove 26. The through grooves are arranged between the upper and lower damping frames. The lubricating oil in the internal lubrication groove 27 can enter the external lubrication groove 26 through the through grooves, ensuring that the inclined rotating rod 4 can be driven by the internal gear.

[0035] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
