Abstract
Apparatus for use on hot and cold rolling mills for retaining a roller bearing assembly and chock as an integral unit during removal or replacement of a roll. A clamping means of the assembly can be disposed to either engage an annular groove in a necked portion of the roll as during operation of the mill or not engage the groove as during removal or replacement of the roll. The clamping means remains slideably connected to the assembly as the clamping means is disposed for axial movement of the chock and bearing assembly during removal or replacement.
Claims14
On a rolling mill having a support stand, roll chocks mounted on the stand, a roll supported at each end in the roll chocks, each end of the roll having a necked portion with a groove formed in each end, an improved bearing assembly at each end of the roll comprising:
- a. a bearing inner race around the necked portion of the roll,
- b. means restraining the inner race from axial movement,
- c. a bearing outer race fixed to the chock,
- d. rollers interposed between the inner and outer races,
- e. means connecting a-d to the chock to permit the chock and bearing assembly to be slidable as an integral unit on and off the necked end of the roll, and
- f. clamp means engaged in the roll groove and connected to the bearing assembly to restrain the bearing assembly from axial movement during operation of the mill and to permit axial movement on and off the necked end of the roll as an integral unit during removal or replacement of the roll.
On a rolling mill having a support stand, roll chocks mounted on the stand, a roll supported at each end in the roll chocks, each end of the roll having a necked portion with a groove formed in each end, an improved bearing assembly at each end of the roll comprising
- a. a bearing inner race circumscribing the necked portion of the roll,
- b. a bearing inner race retaining ring circumscribing the necked portion of the roll and in lateral contact with the inner race,
- c. a bearing outer race fixed to the chock,
- d. rollers interposed between the inner and outer races,
- e. a pivot plate slideably connected to the retaining ring
- f. a pair of arcuate wings for engaging the roll groove, each pivotally connected at one of its ends to the pivot plate so as to enable pivotal positioning of the wings so as to restrain or permit axial movement of the bearing assembly and chock on the roll,
- g. means for rigidly connecting together distal ends of the arcuate wings opposite the pivoting ends of the arcuate wings,
- h. a threaded nut, threadably connected to the retaining ring and in lateral contact with the arcuate wings, and
- i. means connecting a-h to the chock to permit the chock and bearing assembly to be axially slidable as an integral unit on and off the necked end of the roll during removal or replacement of the roll.
