Abstract
A roller is provided with replaceable shells formed of panels. The roller includes a shaft extending in a longitudinal direction. A center flange and two end flanges are mounted on the shaft and extend radially outward from the shaft at axially spaced locations. Between each end flange and one side of the center flange, a replaceable shell is provided. Preferably, multiple additional center flanges and replaceable shells are mounted on the shaft between the end flanges. An internal pin system is employed to ensure no screws are visible while holding the shell panels in place.
Claims20
A roller comprising:
- a shaft extending in a longitudinal direction and having a central section including an axially facing wall formed with mounting holes;
- a center flange extending radially outward from the shaft;
- an end flange extending radially outward from the shaft and including inner mounting holes and outer mounting holes located radially outward of the inner mounting holes, wherein a fastener extends through one of the inner mounting holes in the end flange aligned with one of the mounting holes in the axially facing wall to fasten the end flange to the shaft;
- and
- a replaceable shell removably mounted on the shaft between the center flange and the end flange.
A roller comprising:
- a shaft extending in a longitudinal direction, the shaft having a central section including an axially facing wall formed with mounting holes;
- a center flange extending radially outward from the shaft;
- an end flange extending radially outward from the shaft, the end flange having inner mounting holes and outer pins located radially outward of the inner mounting holes;
- and
- a replaceable shell removably mounted on the shaft between the center flange and the end flange.
A method of mounting a replaceable shell of a roller comprising:
- mounting an end flange, formed with inner mounting holes and outer mounting holes located radially outward of the inner mounting holes, on a shaft extending in a longitudinal direction and having a center flange extending radially outward from the shaft and a central section including an axially facing wall formed with mounting holes;
- fastening the end flange to the shaft by placing fasteners through the inner mounting holes in the end flange which are aligned with the mounting holes in the axially facing wall of the shaft;
- fastening the replaceable shell to the end flange by passing fasteners mounted on the end flange into mounting holes in the replaceable shell;
- and
- fastening a center flange to the replaceable shell by passing fasteners mounted on the center flange into mounting holes in the replaceable shell so that the replaceable shell is removably mounted on the shaft between the center flange and the end flange.
