Abstract
There is provided a cast tire for use with a furnace roller. The cast tire has at least three of annular spaced pockets located around the central opening of the tire on each radial side. When the tires are installed on a furnace roller with arbor means, pockets are inserted into the annular spaced pockets. The pockets are secured only to the arbor means of the roller. Rotation of the arbor means results in rotation of the cast tires by transmission of torque from the pockets to the to the tire without direct attachment of the tire to the arbor means.
Claims27
A cast tire for use in a furnace roller to support and advance a workpiece in a furnace, said cast tire including:
- an outer rim portion having an annular peripheral tire face to engage and support a workpiece during conveyance thereof in a heated chamber of a furnace;
- and
- a continuous web portion having an inner most annular surface contiguous with said outer rim portion, said inner most annular surface defining a load-bearing seat for load-bearing support by an axle, said continuous web portion having oppositely directed radial face surfaces forming boundaries of angularly spaced pockets bounded by radial edges generally perpendicular to said inner most annular surface, said radial edges being elongated to form moment arms to transmit torque from an applied force by an axle to rotate said continuous web portion and said outer rim portion for conveying a workpiece.
A furnace roller for supporting a workpiece in a furnace, the furnace roller including:
- a rotatable arbor;
- a number of tires having substantially equal radial extending outer rim portions at axially spaced apart sites along said arbor for engaging a workpiece, each tire further comprising a continuous web portion having an inner most annular surface contiguous with said outer rim portion thereof, said inner most annular surface defining a load bearing seat for load bearing support by an axle, said continuous web portion having oppositely directed radial face surfaces forming boundaries of angularly spaced pockets bounded by radial edges generally perpendicular to said inner most annular surface, said radial edges being elongated to form moment arms to transmit torque from an applied force by an axle to rotate said continuous web portion and said outer rim portion for conveying a workpiece;
- a plurality of anchor members seated in said pockets and drivingly secured to said arbor for rotation by the arbor;
- and
- thermal insulation supported by said arbor to provide a thermal barrier to extend radially between the tires, the insulation having a thickness terminating with an outer surface extending radially at least a substantial portion but less than the entire radii of the tires.
