Abstract
A drive belt for use in a roller assembly includes a main body having a radially inwardly extending arcuate portion, a first flanged portion projecting axially from a first end of the arcuate portion, and a second flanged portion projecting axially from a second end of the arcuate portion. At least one reinforcement is embedded within the main body. The first and second flanged portions of the main body are configured to prevent a rolling of the main body during operation of the drive belt when received within a groove of a rotary component.
Claims19
A drive belt for use in a roller assembly, the drive belt comprising:
- a main body having a constant cross-sectional shape extended circumferentially into a closed and continuous loop such that the constant cross-sectional shape is present at all circumferential positions disposed along the loop formed by the main body, wherein an axial direction of the main body is arranged perpendicular to the circumferential direction of extension of the constant cross-sectional shape with respect to all circumferential positions disposed along the loop formed by the main body, and wherein a radial direction of the main body at each of the respective circumferential positions disposed along the loop formed by the main body is arranged perpendicular to each of the axial direction of the main body and the circumferential direction of the main body at the corresponding circumferential position disposed along the loop formed by the main body, and wherein the constant cross-sectional shape present at each of the respective circumferential positions along the loop formed by the main body is disposed along a plane defined by the axial direction of the main body and the radial direction of the main body at the corresponding circumferential position disposed along the loop formed by the main body, the constant cross-sectional shape comprising:
- an inner circumferential surface of the main body including a radially inwardly extending arcuate portion, a first flanged portion projecting axially away from a first axial end of the arcuate portion, and a second flanged portion projecting axially away from a second axial end of the arcuate portion.
A roller assembly comprising:
- a first roller having a circumferentially extending groove formed in an outer circumferential surface thereof, the groove defined by a groove forming surface indented radially inwardly into the outer circumferential surface of the first roller;
- and
- a drive belt configured to transfer motion between the first roller and the drive belt when a portion of the drive belt is received within the groove and engaging the groove forming surface of the first roller, the drive belt comprising a main body having a constant cross-sectional shape extended circumferentially into a closed and continuous loop loop such that the constant cross-sectional shape is present at all circumferential positions disposed along the loop formed by the main body, wherein an axial direction of the main body is arranged perpendicular to the circumferential direction of extension of the constant cross-sectional shape with respect to all circumferential positions disposed along the loop formed by the main body, and wherein a radial direction of the main body at each of the respective circumferential positions disposed along the loop formed by the main body is arranged perpendicular to each of the axial direction of the main body and the circumferential direction of the main body at the corresponding circumferential position disposed along the loop formed by the main body, and wherein the constant cross-sectional shape present at each of the respective circumferential positions along the loop formed by the main body is disposed along a plane defined by the axial direction of the main body and the radial direction of the main body at the corresponding circumferential position disposed along the loop formed by the main body, the constant cross-sectional shape of the main body having a radially inwardly extending arcuate portion, a first flanged portion projecting axially away from a first axial end of the arcuate portion, and a second flanged portion projecting axially away from a second axial end of the arcuate portion.
