Abstract

A system for securing objects having different coefficients of thermal expansion (CTE) includes a low-level CTE member having a first CTE, a high-level CTE member having a second CTE greater than the first CTE, and a compensation member positioned adjacent to the low-level CTE member and the high-level CTE member, the compensation member having a compensation CTE greater than the second CTE. The low-level CTE member includes an engagement surface and the high-level CTE member includes an engagement surface facing the engagement surface of the low-level CTE member such that, when the system is heated, expansion of the low-level CTE member and the high-level CTE member results in an increased distance between the engagement surface of the low-level CTE member and the engagement surface of the high-level CTE member. However, expansion of the compensation member maintains a secure connection between the low-level CTE member and the high-level CTE member.

Dependent claims

A roll assembly utilizing members having different coefficients of thermal expansion (CTE), comprising:

a cylindrical body having a first CTE, the body defining an internal cavity with a distal end of the body open to the internal cavity;
a compensation member positioned within the open distal end of the body, the compensation member defining a through hole and including a sloped engagement surface surrounding the through hole;
a journal positioned against the compensation member with a first sloped engagement surface of the journal in contact with the sloped engagement surface of the end bell, the journal defining a through hole aligned with the through hole of the compensation member;
a rod having a second CTE greater than the first CTE, the rod extending through the through hole of the journal and the through hole of the compensation member, the rod terminating in a distal end operably connected to a distal end of the compensation member and positioned within the internal cavity of the body;
and
a nut operably connected to a proximal end of the rod opposite the distal end of the rod, the nut including an engagement surface in contact with a second engagement surface of the journal opposite the first sloped engagement surface of the journal, the nut and rod configured to maintain a secure connection between the first sloped engagement surface of the journal and the sloped engagement surface of the compensation member;
wherein, the compensation member has a compensation CTE greater than the second CTE, such that, when the roll assembly is heated, expansion of the rod results in an increased distance between the distal end of the rod and the journal, and expansion of the compensation member maintains the secure connection between the sloped engagement surface of the journal and the sloped engagement surface of the compensation member.
