5) The jack is lightly jacked, and the adjusting bolt is properly adjusted to lead the tapered guide shaft sleeve to enter the shaft hole.

6) The jack is pressed to make the shaft enter the bearing seat, and the distance ring of the bearing seat is installed at the same time.

7) And (5) removing the auxiliary tool after the shaft is installed in place.

8) And (5) installing a shaft end cover and performing subsequent work.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
