A first bearing 301, an upper shaft sleeve plate 302 and a lower shaft sleeve plate 303 are respectively arranged inside the first bearing groove 3. A cast aluminum bearing plate 4 is arranged above the centrifuge main body 1. An installation cavity 5 is opened inside the centrifuge main body 1. A main shaft 6 and a second bearing groove 7 are respectively arranged inside the installation cavity 5. A slave sprocket 601 is fixedly sleeved on the outer side of the main shaft 6. A second bearing 701 and a shaft cover 702 are respectively arranged inside the second bearing groove 7. The output end of the driving motor 2 is fixedly installed with a main sprocket 201;
[0027] Specifically, the inner wall at the bottom end of the first bearing groove 3 extends into the interior of the installation cavity 5. The upper sleeve plate 302 is fixed to the top surface of the centrifuge main body 1 by screws, and the lower sleeve plate 303 is fixed to the top inner wall of the installation cavity 5 by screws. The bottom surface of the upper sleeve plate 302 and the top surface of the lower sleeve plate 303 are respectively in contact with the top and bottom ends of the first bearing 301. The shaft cover 702 is fixed to the inner wall at the bottom end of the installation cavity 5 by screws, and the bottom of it is closely attached to the top side of the second bearing 701;
[0028] In this embodiment, the upper sleeve plate 302 and the lower sleeve plate 303 are mainly used to limit the first bearing 301, so that the first bearing 301 is in stable contact with the first bearing groove 3. The shaft cover 702 is mainly used to limit the second bearing 701, so that the second bearing 701 is in stable contact with the second bearing groove 7, which is convenient for subsequent support of the main shaft 6.
[0029] Specifically, both the first bearing 301 and the second bearing 701 are sleeved on the outer surface of the main shaft 6. The top end of the main shaft 6 sequentially passes through the bottom center surface of the lower sleeve plate 303 and the upper sleeve plate 302 in a movable manner and is fixedly connected to the bottom center of the cast aluminum bearing plate 4. The bottom end of the main shaft 6 passes through the top surface of the shaft cover 702 in a movable manner and extends downward;
[0030] In this embodiment, the rotation support is formed between the first bearing 301 and the second bearing 701 and the main shaft 6, so that the load during the operation of the centrifuge is dispersed, the wear of a single bearing is reduced, and the service life of the centrifuge is guaranteed.
[0031] Specifically, the inner diameter of the main shaft 6 is 220 mm;
[0032] In this embodiment, by increasing the inner diameter of the main shaft 6, the load-bearing capacity of the centrifuge is improved.

[0035] Working process of the utility model: When using a heavy cast aluminum rotor centrifuge, first start the driving motor 2. Then, the output end of the driving motor 2 drives the main sprocket 201 to rotate. The main sprocket 201 drives the driven sprocket 601 to rotate through a chain. The driven sprocket 601 drives the main shaft 6 to rotate. At this time, the main shaft 6 rotates in cooperation with the first bearing 301 and the second bearing 701 and drives the cast aluminum carrier plate 4 to rotate centrifugally, thus facilitating subsequent centrifugal operations. Further, the first bearing 301 and the second bearing 701 can provide better radial and axial support for the main shaft 6, improving the stability of the centrifuge during operation. At the same time, it can effectively disperse the load, reduce the wear of a single bearing, improve the practical effect of the centrifuge, and meet the needs of users.
