[0008] In order to supply oil to the oil film bearing, further, the oil supply groove is arranged on the inner wall of the installation circular groove.

[0009] In order to match the taper box, avoid the situation of not being installed in place, further, the bottom of the panel body is provided with a first empty slot on one side of the boss. The inside of the first empty slot is provided with two second empty slots.

[0010] In order to maximize the wrapping of the eccentric sleeve without affecting the elevation adjustment, prevent the eccentric sleeve from being deformed in use, further, the thickness of the panel body is 127mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1、The utility model discloses a first cut groove and the eccentric sleeve of the taper box are matched, interference is avoided, a boss is arranged at the middle position of the two first cut grooves, the contact area of the boss and the eccentric sleeve assembly is increased, the panel body and the boss maximize the wrapping of the eccentric sleeve, prevent the eccentric sleeve from being deformed in use, avoid the oil film self-rotation to cause the serious accident of the roller box burning oil film.

[0013] 2、The two installation circular grooves are close to tangency, therefore, through the setting of the second cut groove, the problem of breaking and falling in the working process due to the thin thickness of the tangency can be avoided.

[0014] 3、The utility model discloses that the thickness of the panel body is increased, and the height of the roller box body is correspondingly reduced, the eccentric sleeve is maximized in wrapping without affecting the elevation adjustment, and the eccentric sleeve is prevented from being deformed in use.
