Abstract
A water-coolable furnace roller for conveying goods to be transported through a roller hearth heating furnace has a shaft supported external to the furnace and driven in rotation. The shaft has an outer contact surface. Support rings having a receiving bore, respectively, are arranged with the receiving bore on the shaft, wherein the support rings form a conveying plane. The receiving bore has an inner contact surface, and at least one of the inner and the outer contact surfaces has a shape of a polygon contour of substantially constant diameter with fitting surfaces defining an orbiform curve.

A water-coolable furnace roller for conveying goods to be transported through a roller hearth heating furnace, the furnace roller comprising:
- a shaft configured to be supported external to the furnace and to be driven in rotation;
- the shaft having an outer contact surface;
- support rings having a receiving bore, respectively, and arranged with the receiving bore on the shaft, wherein the support rings form a conveying plane;
- wherein the receiving bore has an inner contact surface and wherein at least one of the inner and the outer contact surfaces has a shape of a polygon contour of substantially constant diameter with fitting surfaces defining an orbiform curve, wherein the fitting surfaces have a deviation from a circular shape and wherein the deviation provides a self-locking action when torque is transmitted between the support ring and the shaft, and wherein the deviation of the fitting surfaces from the circular shape is substantially 4% to 5%.
A water-coolable furnace roller for conveying goods to be transported through a roller hearth heating furnace, the furnace roller comprising:
- a shaft configured to be supported external to the furnace and to be driven in rotation;
- the shaft having an outer contact surface;
- support rings having a receiving bore, respectively, and arranged with the receiving bore on the shaft, wherein the support rings form a conveying plane;
- wherein the receiving bore has an inner contact surface and wherein at least one of the inner and the outer contact surfaces has a shape of a polygon contour of substantially constant diameter with fitting surfaces defining an orbiform curve, wherein a metallic contact provided by the orbiform curve is realized across the entire width of the furnace roller.
