Abstract
A conveyor roller having a low noise level and a long wear life consisting of a steel shaft, an intermediate layer made of a polymeric material (e.g., fiberglass-reinforced polyester) bonded to the shaft, a helical steel spring wear element situated around the periphery of the intermediate layer, and an outer layer made of an abrasion-resistant polymeric material bonded to the intermediate layer and the wear element. This roller solves the problem of high noise levels in steel plants, yet also exhibits long wear life.

A conveyor roller having a low noise level and a long wear life comprising:
- (1) a central shaft;
- (2) an intermediate layer composed of a polymeric material bonded to the shaft;
- (3) a hard wear element positioned around the periphery of the intermediate layer and having a pre-determined thickness;
- and
- (4) an outer layer composed of an abrasion-resistant polymeric material bonded to the intermediate layer and to the wear element and having a thickness substantially equal to the thickness of the hard wear element, whereby the hard wear element produces a long wear life and the polymeric materials produce a low noise level.
A quick disconnect conveyor roller having a low noise level and a long wear life comprising:
- (1) a central hollow core;
- (2) an intermediate layer composed of a polymeric material bonded to the central core;
- (3) a hard wear element positioned around the periphery of the intermediate core and having a pre-determined thickness;
- (4) an outer layer consisting of an abrasion-resistant polymeric material bonded to the intermediate core and to the wear element and having a thickness substantially equal to the thickness of the hard wear element, whereby the hard wear element produces a long wear life and the polymeric materials produce a low noise level;
- and
- (5) a pair of end plates having central apertures.
In a shear line including an input conveyor and an output conveyor, the improvement consisting of using in the input conveyor and in the output conveyor, conveyor rollers having a low noise level and a long wear life, said conveyor rollers comprising:
- (1) a central shaft;
- (2) an intermediate layer composed of a polymeric material bonded to the shaft;
- (3) a hard wear element positioned around the periphery of the intermediate layer and having a pre-determined thickness;
- and
- (4) an outer layer composed of an abrasion-resistant polymeric material bonded to the intermediate layer and to the wear element and having a thickness substantially equal to the thickness of the hard wear element, whereby the hard wear element produces a long wear life and the polymeric materials produce a low noise level.
In a shear line including an input conveyor and an output conveyor, the improvement consisting of using in the input conveyor and in the output conveyor, quick disconnect conveyor rollers having low noise level and a long wear life, said quick disconnect conveyor rollers comprising:
- (1) a central hollow core;
- (2) an intermediate layer composed of a polymeric material bonded to the central core;
- (3) a hard wear element positioned around the periphery of the intermediate core and having a pre-determined thickness;
- (4) an outer layer consisting of an abrasion-resistant polymeric material bonded to the intermediate core and to the wear element and having a thickness substantially equal to the thickness of the hard wear element, whereby the hard wear element produces a long wear life and the polymeric materials produce a low noise level;
- and
- (5) a pair of end plates having central apertures.
