MACHINE SYSTEM HAVING MACHINERY ROLLER ASSEMBLY WITH STATIC SEALING CLAMPING COLLARS

Abstract:

A machine system includes a roller frame and a roller assembly mounted to the roller frame. The roller assembly includes first and second clamping collars positioned upon a roller shaft and each including a lower and an upper collar section. Fasteners clamp the lower and upper collar sections to the roller shaft to form static seals. The clamping collars may be formed with splitlines to enable the clamping collars to deform so as to simulate interference fits with the roller shaft.
