[0030] Example 2: On the basis of Example 1, when installing the rolling bearing 6, directly install the bearing edge into the bearing combination seat 4, and use a rubber hammer to knock for installation.

When installing the rolling bearing 6, directly install the edge of the bearing into the bearing combination seat 4, and use a rubber hammer to tap for installation. As the installation depth of the rolling bearing 6 increases, the resistance increases. Then directly install the bearing cover 5, and install the bearing cover 5 through threaded connection. The bearing cover 5 provides a pushing force, and while fixing the bearing cover 5, the rolling bearing 6 is pushed into the bearing combination seat 4 for fixation; for the installation of the bearing cover 5, use a flat mouth drift tool for installation. Insert the flat mouth drift into the drift slot 501, and use the method of hammering the drift to generate an impact force to install the bearing cover 5.

During the rotation of the intermediate ring 7, drive the helical gear 702 to rotate; since the thrust ring 8 is slidably connected to the semi-circular through groove 402 and can only move axially, the helical gear 702 provides a force during the turnover process to push the inclined flange 802 outwards, and then use the thrust cylinder 801 to push the rolling bearing 6 outwards, achieving the effect of synchronously disassembling the two rolling bearings 6 on both sides. The two arc-shaped through grooves 403 also limit the position of the drift teeth 701, ensuring that the intermediate ring 7 is centered, and ensuring that the impact force of the drift synchronously disassembles the two rolling bearings 6 on both sides.
