Reinforcement to reduce noise and improve flexural strength for metal rollers
An example roller is provided. The example roller can include a metal tube extending between a first end and a second end, where the metal tube includes an outer surface and an inner surface. The example roller can include a first bearing disposed at the first end. The example roller can include a second bearing disposed at the second end. The example roller can include a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling is made at least partially of a non-metal material.
1 . A roller, comprising:
a metal tube extending between a first end and a second end, wherein the metal tube comprises an outer surface and an inner surface;
a first bearing disposed at the first end;
a second bearing disposed at the second end; and
a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling is made at least partially of a non-metal material, wherein the reinforcement filling comprises a plurality of corrugated sheets, and wherein at least a first corrugated sheet of the plurality of corrugated sheets is oriented on a horizontal plane, at least a second corrugated sheet of the plurality of corrugated sheets is oriented on a second plane diagonal to the horizontal plane, and at least a third corrugated sheet of the plurality of corrugated sheets is oriented on a third plane diagonal to the second plane and the horizontal plane.
2 . The roller of claim 1 , wherein the reinforcement filling fills a space inside the metal tube and between the first bearing and the second bearing.
3 . The roller of claim 1 , further comprising a shaft, wherein the shaft extends through the metal tube and between the first bearing and the second bearing.
4 . The roller of claim 3 , wherein the reinforcement filling fills a space inside the metal tube, outside the shaft, and between the first bearing and the second bearing.
5 . The roller of claim 1 , wherein the reinforcement filling comprises a corrugated plastic filling.
6 . The roller of claim 5 , wherein the corrugated plastic filling comprises at least one of a honeycomb reinforcement structure, a bubble reinforcement structure, a rectangular reinforcement structure, or a plate reinforcement structure.
7 . The roller of claim 5 , wherein the corrugated plastic filling comprises the plurality of corrugated sheets.
8 . The roller of claim 6 , wherein each of the plurality of corrugated sheets are stacked in a direction extending between the first bearing and the second bearing.
9 . The roller of claim 7 , wherein each of the plurality of corrugated sheets defines a circular shape.
10 . The roller of claim 6 , wherein each of the plurality of corrugated sheets is disposed between two reinforcement layers.
11 . The roller of claim 9 , wherein each of the plurality of corrugated sheets is further disposed between two surface treatment layers.
12 . The roller of claim 7 , wherein the plurality of corrugated sheets are fused together.
13 . The roller of claim 1 , wherein the reinforcement filling comprises a silicone-based powder.
14 . The roller of claim 1 , further comprising a motor positioned inside the metal tube.
15 . The roller of claim 14 , wherein the reinforcement filling fills a space inside the metal tube, outside the motor, and between the first bearing and the second bearing.
16 . The roller of claim 1 , wherein the metal tube comprises 20 gauge metal.
17 . The roller of claim 1 , wherein at least one of the first bearing or the second bearing comprises at least one of a hex shaft or a circular shaft.
18 . A roller conveyor system, comprising:
one or more conveyor frames;
one or more conveyor legs; and
one or more rollers, each of the one or more rollers comprising:
a metal tube extending between a first end and a second end, wherein the metal tube comprises an outer surface and an inner surface;
a first bearing disposed at the first end;
a second bearing disposed at the second end; and
a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling comprises a silicone-based powder.
19 . The roller conveyor system of claim 18 , wherein the reinforcement filling fills a space inside the metal tube and between the first bearing and the second bearing.
20 . The roller conveyor system of claim 18 , further comprising a shaft, wherein the shaft extends through the metal tube and between the first bearing and the second bearing.
