ISOLATING TORQUE COUPLER |
摘要 |
An isolating torque coupler includes a drive element assembled between annular cage elements of a driven element. The cage elements each include a plurality of aligned voids. The drive element includes a hub portion and a plurality of lobes with each of the lobes including a first edge and a second edge. Openings in the drive element are aligned with the voids of the cage elements to accommodate isolator springs. Each isolator spring is a helical coil compression spring having squared ends. A first edge of each of the lobes of the drive element is parallel to a second end of the corresponding one of the voids of the driven element. A second edge of each of the lobes of the drive element is non-parallel to a first end of the corresponding one of the voids of the driven element. |

1. An isolating torque coupler rotatably coupling a rotatable drive member and a rotatably driven member, comprising:
a disk-shaped drive element positioned between first and second annular cage elements that are assembled onto a driven element; the first and second annular cage elements each defining an outer periphery and a plurality of aligned voids, each void having a substantially rectangular shape including first and second sides and first and second ends; the drive element including a hub portion and a plurality of lobes formed near the outer periphery, the lobes defining a plurality of openings formed near the outer periphery, wherein each of the lobes includes a first edge and a second edge; the plurality of openings of the drive element aligned with the voids of the first and second cage elements to accommodate a corresponding plurality of isolator springs inserted therein; each isolator spring being a helical coil compression spring having squared first and second ends; the first edge of each of the lobes of the drive element being contiguous with the first end of each of a corresponding one of the voids of the driven element; the second edge of each of the lobes of the drive element being contiguous with the second end of each of a corresponding one of the voids of the driven element; the first edge of each of the lobes of the drive element being parallel to the second end of the corresponding one of the voids of the driven element; the second edge of each of the lobes of the drive element being non-parallel to the first end of the corresponding one of the voids of the driven element. |
