Abstract
A quick release roller sleeve and mounting hub assembly is described for use with high speed roller machines. The assembly includes an outer flange plate that can be detached from the assembly in order for the roller sleeve to be dismounted and a new roller sleeve mounted as the existing roller sleeve becomes worn and needs to be replaced. The quick release permits the mounting hub and other parts of the assembly to remain in their aligned configuration and positions while only exchanging the roller sleeve portion of the assembly.
Claims11
A quick release roller sleeve assembly for use in high speed rotational machinery comprising:
- a hub for rotationally mounting to the machinery having an external support surface spaced outward from its longitudinal center describing a cylindrical shape, said hub once mounted and aligned for high speed rotational movement remains mounted to the machinery;
- a roller sleeve dimensioned for sliding over and engaging the external support surface of the hub, said roller sleeve having an inner core that is minimally compressible at its ends for inward clamping and an outer shell for contacting a workpiece;
- said hub having inner and outer flange plates for securing the roller sleeve in position on the external support surface of the hub, said outer flange plate located at the proximal exposed outer end of the hub and said inner flange plate located at the distal end of the hub attached to the machinery;
- each of said inner and outer flange plates having an annular recess for mating with the minimally compressible ends of a first section of the roller sleeve to capture said roller sleeve, creating a seal between the outer shell of the roller sleeve and the hub, and retaining the roller sleeve in an aligned position about the hub for synchronized rotational movement with the hub;
- said outer flange plate capable of being readily removed from the assembly for replacing the roller sleeve,
- whereby only said outer flange plate is required to be removed and reinstalled to effect a replacement of the roller sleeve about the hub without removing and reinstalling the hub onto the high speed rotational machinery.

A method for replacement of a quick release roller sleeve assembly for use in high speed rotational machinery comprising the steps of:
- rotationally mounting a hub at its distal end to the high speed rotational machinery, said hub having an external support surface extending between its distal and proximal ends spaced outward from its longitudinal center describing a cylindrical shape;
- providing inner and outer flange plates at the proximal and distal ends of the hub, said outer flange plate being located at the proximal exposed outer end of the hub and said inner flange plate being located at the distal end of the hub attached to the machinery, for securing a roller sleeve in position on the external support surface of the hub, said roller sleeve having an inner core that is minimally compressible at its ends for inward clamping and an outer shell for contacting a workpiece;
- providing each of said inner and outer flange plates with an annular recess for mating with the minimally compressible ends of the roller sleeve to capture said roller sleeve, creating a seal between the outer shell of the roller sleeve and the hub, and retaining the roller sleeve in an aligned position about the hub for synchronized rotational movement with the hub;
- removing said outer flange plate from the outer exposed end of the hub exposing the core of the roller sleeve, removing said roller sleeve from the hub, and positioning a new roller sleeve dimensioned for sliding over and engaging the external support surface of the hub onto the hub;
- replacing said outer flange plate capturing the minimally compressible ends of the roller sleeve in the annular recesses of the outer and inner flange plates at the opposite ends of the hub and clamping the roller sleeve in position about the hub with the tightening of only the outer flange plate,
- whereby only said outer flange plate is required to be removed and reinstalled to effect a replacement of the roller sleeve about the hub without removing and reinstalling the hub onto the high speed rotational machinery.
