[0049] By adopting the above technical solution, the first fixing cylinder 401 and the second fixing cylinder 402 can clamp and fix the bearing body 3 .
[0050] A method for preparing a combined metal bearing seat comprises the following steps:
[0051] Step 1: first, insert the bearing body 3 into the inner ring of the fixing ring 201, then rotate the fixing mechanism 4, so that the connecting block 209 and the rotating rod 208 connected to the fixing mechanism 4 rotate inside the fixing sleeve 206, so that the second fastening nut 403 on the fixing mechanism 4 is aligned with the threaded hole on the fixing ring 201;
[0052] Step 2: Rotate the rotating column 409 to rotate the second gear 410 accordingly. The rotation of the second gear 410 drives the inner gear ring 408 to rotate. The rotation of the inner gear ring 408 drives the rotating ring 406 to rotate. The rotation of the rotating ring 406 drives the outer gear ring 407 to rotate.

[0053] Step three, rotate the threaded sleeve 102 to make the moving blocks 104 connected by the two threaded rods 103 inside the threaded sleeve 102 move toward each other, so that the two moving blocks 104 can move to the fixing holes of the machine, and then rotate the first fastening nut 105 to fix the bearing seat on the machine. After the installation is completed, add a proper amount of lubricating oil to the oil inlet hole 204, and the lubricating oil passes through the oil storage chamber 203 and the oil outlet hole 205 to the lubrication hole 306 of the annular groove 305 to lubricate the rotating part 302. A part of the lubricating oil will be stored in the oil storage chamber 203 to achieve continuous lubrication of the rotating part 302.
[0054] Working principle: When the present invention is used, firstly, the bearing body 3 is inserted into the inner ring of the fixing ring 201, and then the fixing mechanism 4 and the connecting block 209 are rotated, so that the rotating rod 208 and the second limiting ring 207 connected to the connecting block 209 are rotated inside the fixing sleeve 206, so that the second fastening nut 403 on the fixing mechanism 4 is aligned with the threaded hole on the fixing ring 201;
[0055] The rotating column 409 is rotated by a hexagonal wrench. The rotating column 409 rotates to drive the second gear 410 to rotate. The second gear 410 rotates to drive the inner gear ring 408 to rotate. The inner gear ring 408 rotates to drive the rotating ring 406 to rotate on the slide rail 405. The rotating ring 406 rotates to drive the outer gear ring 407 to rotate. The outer gear ring 407 rotates to drive the plurality of first gears 404 to rotate. The first gear 404 rotates to drive the second fastening nuts 403 to rotate. The plurality of second fastening nuts 403 can be simultaneously threadedly inserted into the interior of the fixing ring 201 as the rotating column 409 continues to rotate, thereby fixing the outer ring 303 of the bearing.
[0056] By rotating the threaded sleeve 102, the moving block 104 connected by the two threaded rods 103 inside the threaded sleeve 102 moves toward each other. When moving, the moving block 104 uses the guide rod 106 to slide inside the base 101 to limit the movement process of the moving block 104, so that the two moving blocks 104 can move to the fixing hole of the machine, and then the first fastening nut 105 is rotated to fix the bearing seat on the machine. After the installation is completed, a proper amount of lubricating oil is added to the oil inlet hole 204. The lubricating oil passes through the oil storage chamber 203 and the oil outlet hole 205 to the annular groove 305 of the bearing outer ring 303, and then flows from the lubrication hole 306 to the rotating part 302 for lubrication. A part of the lubricating oil will be stored in the oil storage chamber 203 to achieve continuous lubrication of the rotating part 302.
[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
