Abstract
Abstract Apparatus for mounting a multi-groove work roll on a roll shaft in a rolling mill. The apparatus includes a shoulder on the roll shaft, a spacer assembly on the roll shaft in engagement at one end with the shoulder, the opposite end of the spacer assembly being in engagement with a work roll axially received on the roll shaft, and a retainer assembly for holding the work roll against the spacer assembly in an operative position with one of the roll grooves aligned with the mill pass line. The spacer assembly includes at least one removable element, the presence or absence of which will change the axial length of the spacer assembly by a distance equal to the spacing between the centers of adjacent grooves on the work roll.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
In a rolling mill, apparatus for mounting a multigroove work roll on the end section of a roll shaft in an operative position with one of the roll grooves in alignment with the mill pass line, said apparatus comprising: locating means on the roll shaft, spacer means positioned between and engageable at opposite ends respectively with said locating means and with one end of a multi-groove work roll which is axially received on the roll shaft, and retaining means engageable with the roll shaft and with the other end of the work roll for holding the work roll against said spacer means in a fixed position on said shaft, said spacer means including at least one removable element, the presence or absence of which will change the axial length of the spacer means by a distance equal to the spacing between adjacent grooves on the work roll.
Claim 2
Dependent Claim
147 words
In a rolling mill, apparatus for mounting a multigroove work roll on the end section of a roll shaft in an operative position with one of the roll grooves in alignment with the mill pass line, said apparatus comprising: locating means on the roll shaft, spacer means positioned between and engageable at opposite ends respectively with said locating means and with one end of a multi-groove work roll which is axially received on the roll shaft, and retaining means engageable with the roll shaft and with the other end of the work roll for holding the work roll against said spacer means in a fixed position on said shaft, said spacer means including at least one removable element, the presence or absence of which will change the axial length of the spacer means by a distance equal to the spacing between adjacent grooves on the work roll.
Claim 3
Dependent Claim
20 words
The apparatus as claimed in claim 1 wherein said locating means is comprised of a shoulder on the roll shaft.
Claim 4
Dependent Claim
49 words
The apparatus as claimed in claim 2 wherein said roll shaft protrudes axially from a housing containing lubricated shaft bearings, and wherein said spacer means includes one section of a labyrinth-type seal, the said one section being in engagement with said shoulder and being rotatable with the roll shaft.
Claim 5
Dependent Claim
40 words
The apparatus as claimed in claim 3 further characterized by another section of said labyrinth-type seal fixed to the roll housing and cooperating with said one section to establish a sealing relationship between the roll shaft and the roll housing.
Claim 6
Dependent Claim
58 words
The apparatus as claimed in claim 1 wherein said retaining means includes a key member extending transversally through a slot in the roll shaft, said key member being engageable with the other end of the work roll, and adjustable means in engagement with and acting through said key member to hold the work roll against said spacer means.
Claim 7
Dependent Claim
111 words
In a rolling mill, apparatus for mounting a multi-groove work roll on the end of a roll shaft, comprising: locating means on the roll shaft; spacer means axially mounted on the roll shaft, said spacer means being in engagement at opposite ends with said locating means and with one end of the multi-groove work roll which is also axially mounted on the roll shaft; retainer means engageable with the roll shaft and the work roll for holding the work roll against the spacer means, said spacer means including at least one removable element having an axial length equal to the spacing between the centers of adjacent grooves on said work roll.
Claim 8
Dependent Claim
111 words
In a rolling mill, apparatus for mounting a multi-groove work roll on the end of a roll shaft, comprising: locating means on the roll shaft; spacer means axially mounted on the roll shaft, said spacer means being in engagement at opposite ends with said locating means and with one end of the multi-groove work roll which is also axially mounted on the roll shaft; retainer means engageable with the roll shaft and the work roll for holding the work roll against the spacer means, said spacer means including at least one removable element having an axial length equal to the spacing between the centers of adjacent grooves on said work roll.
