One-piece flexible coupling having a plurality of axially spaced disks
First Claim
Patent Images
1. A shaft coupling comprising:
- a first and a second shaft connector and both centered on a central axis and spaced axially from each other;
a plurality of solid cylindrical discs spaced between said first and second shaft connectors, a first disc being defined as the disc most adjacent said first shaft connector, and a second disc being the next adjacent disc in a direction towards said second shaft connector, said first shaft connector being integral with said first disc;
said first disc being connected to said second disc by a post extending at each of two circumferentially spaced positions about said central axis, there being slots formed between said first and second discs over the remainder of their circumferential extends;
said second disc and a third disc being connected by a post extending at each of two circumferentially spaced positions about said central axis, there also being slots between said second and third discs over the remainder of their circumferential extents, said post between said first and second discs being circumferentially offset by 90°
relative to said posts between said second and third discs; and
said discs, said shaft connectors, and said posts being integrally formed of a polymer.

Abstract
A one-piece flexible coupling is integrally molded from plastic. A plurality of discs are connected by posts over small circumferential extents with slots formed over the remainder of the circumferential extent of the discs. The posts between adjacent discs are offset by 90° from the previous and subsequent discs. Shafts are connected at both ends of the flexible coupling, and the flexible coupling transmit rotation between the shafts, even when they are at non-parallel angles relative to each other.
