Abstract
A link for a modular conveyor belt may include a supporting structure and a bearing structure covering at least a portion of the supporting structure. The supporting structure may have a tensile strength that is higher than the bearing structure, and the bearing structure may be more resistant to wear than the supporting structure.
Claims53
A link for a modular conveyor belt configured to be attached to a connecting rod, comprising:
- a supporting structure having a surface that at least partially defines a shape of the supporting structure;
- and
- a bearing structure that is attached to the supporting structure, the bearing structure having a predetermined outer shape that is independent of the shape of the supporting structure, the bearing structure having a covering portion covering at least a portion of the surface of the supporting structure, the covering portion configured to be disposed between the surface and the connecting rod, the covering portion configured to abut the connecting rod and separate the surface away from the connecting rod;
- wherein the supporting structure has a tensile strength that is higher than the bearing structure;
- and
- wherein the bearing structure is more resistant to wear than the supporting structure.
3 more elements
A link for a modular conveyor belt including an elongated connecting rod, the link comprising:
- a supporting structure formed of a first material, wherein the supporting structure includes a contour that establishes a shape of the composite link, and wherein the supporting structure has a surface;
- and
- a bearing structure formed of a second material, the bearing structure being overmolded on the supporting structure, the bearing structure having a covering portion, wherein the covering portion of the bearing structure is located on the surface of the supporting structure;
- wherein the covering portion of the bearing structure is configured to be disposed between the surface and the connecting rod to prevent the connecting rod from contacting the surface of the supporting structure.
1 more element
A modular conveyor belt, comprising:
- at least a first link and a second link;
- and
- an elongated connecting rod configured to hingedly attach the first link and the second link to one another;
- wherein the first link includes a supporting structure and a bearing structure, the bearing structure including a covering portion covering a surface of the supporting structure, the covering portion disposed between the surface and the connecting rod, the covering portion configured to abut the connecting rod and separate the surface away from the connecting rod, the supporting structure having a tensile strength that is higher than the bearing structure, and the bearing structure being more resistant to wear than the supporting structure;
- wherein the bearing structure is removably attached to the support structure;
- and
- wherein the bearing structure has a thickness measured substantially normal to the supporting structure;
- and
- wherein the thickness of the bearing structure in a first area of the first link is different from the thickness of the bearing structure in a second area of the first link.
