Resilient device for splined connection
First Claim
Patent Images
1. A resilient device for reducing play between mating splines in a splined connection, comprising:
- a mounting portion having opposing first and second sides and opposing first and second ends;
first and second flanges extending from the first and second sides of the mounting portion in a first direction, the flanges being substantially parallel and spaced apart from each other by the mounting portion, wherein the first and second flanges and mounting portion together create a substantially U-shaped profile; and
an arm extending from the first end of the mounting portion in a second direction and having a wavy part adjacent to the mounting portion, wherein the wavy part has at least one crest portion and at least one trough portion to engage at least one spline in the splined connection.

Abstract
A resilient device for minimizing noise in a splined connection includes a mounting portion and two flanges bent from the mounting portion to attach to a structure. The flanges are substantially parallel and spaced apart from each other by the mounting portion to form a substantially U-shaped profile. An arm is bent in a second direction from the mounting to lie adjacent to the mounting portion. The arm has a wavy portion having a pitch that allows it to engage with splines in the splined connection to prevent rattling in the connection without having to reduce the clearance between the splines.
