Toothed sprocket with elastic centering element

摘要

A toothed sprocket hub with elastic centering element comprising an input shaft having a receiving portion and a cylindrical outer surface, a sprocket engagable with the input shaft, the sprocket comprising at least two first surfaces each disposed on a bending beam such that each first surface is elastically moveable in a radial direction, the two first surfaces bearing upon the outer surface, the two first surfaces each having a radius d that is less than a radius D of the outer surface, at least one second surface that is radially moveable to a lesser extent than a first surface, the second surface engaging the receiving portion to prevent a relative rotation of the sprocket with the input shaft, and a third surface in cooperative relation to the second surface, the third surface bearing upon the outer surface of the input shaft, the third surface having a clearance fit with the outer surface.

1. A toothed sprocket hub with elastic centering element comprising:
an input shaft having a receiving portion and a cylindrical outer surface; a sprocket engagable with the input shaft; the sprocket comprising at least two first surfaces each disposed on a bending beam such that each first surface is elastically moveable in a radial direction, the two first surfaces bearing upon the outer surface, the two first surfaces each having a radius (d) that is less than a radius (D) of the outer surface; at least one second surface that is radially moveable to a lesser extent than a first surface, the second surface engaging the receiving portion to prevent a relative rotation of the sprocket with the input shaft; and a third surface in cooperative relation to the second surface, the third surface bearing upon the outer surface of the input shaft, the third surface having a clearance fit with the outer surface.
