Plate adapter for flexible half couplings
First Claim
1. A plate adapter for rigidizing a flexible coupling half, said flexible coupling half including a hub adapted to be secured to the shaft of a rotating apparatus and a sleeve interconnected with said hub by means of a flexible disk pack, said plate adapter comprising:
- a main body having a first portion engageable with said hub and an annular flange extending radially from said main body; and
a pilot flange projecting from said annular flange, said pilot flange sized to form an interference fit with a portion of said sleeve;
wherein said plate adapter is spaced away from the flexible disk pack and adapted to rigidize the flexible coupling half when attached thereto.

Abstract
An improved plate adapter for use with flexible couplings is disclosed which incorporates radially outwardly disposed pilot flanges for engagement with the hub and sleeve of the half coupling which pilot flanges are designed to form a pressfit relationship with the mating surfaces of the hub and sleeve. A suitable bolting arrangement is provided to aid in fitting of the adapter plate to the half coupling as well as to assist in removal of same. Additionally, the fastener arrangement enables fine adjustment of the radial runout of the sleeve of the half coupling relative to the axis of rotation of the shaft to which the half coupling is secured.

9. A rigidized flexible coupling half comprising:
-
a hub secured to a rotatable shaft of a driven or a driving machine;
a sleeve telescopically receiving a portion of said hub in one end thereof;
a flexible disk pack secured to said sleeve and to said hub and being operative to transmit rotational forces therebetween; and
a plate adapter having a first pilot flange overengaging a portion of said sleeve to rigidly position said plate adapter relative to said sleeve and a second pilot flange engageable with said hub in a press fit relationship to rigidly position said hub with respect to said plate adapter;
wherein said plate adapter is adapted to simulate the weight of the half coupling of the other of the driven or driving machine. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A rigidized flexible coupling half comprising:
-
a hub adapted to be secured to a shaft, said hub having a plurality of radially outwardly extending circumferentially spaced ears and an end face;
a sleeve having a throughbore having one end positioned in surrounding spaced relationship to a portion of said hub;
a flexible annular disk pack secured to each of said ears and secured to said sleeve at locations circumferentially spaced from said ears;
an adapter plate located axially opposite the one end and having a first flange portion overengaging an outer peripheral surface of said sleeve and a second flange portion overengaging a peripheral surface of said hub adjacent said end face to thereby rigidly retain said sleeve in a predetermined position relative to said hub whereby check runs of said apparatus may be conducted without removal of said rigidized flexible coupling half from said shaft. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A plate adapter for use with a flexible coupling, said flexible coupling including a hub adapted to be secured to the shaft of rotating apparatus and a sleeve interconnected with said hub by means of a flexible disk pack, said plate adapter comprising:
-
a main body having a first portion engageable with said hub and an annular flange extending radially from the main body;
a pilot flange projecting from said main body, said pilot flange sized to form an interference fit with a portion of said sleeve; and
a plurality of threaded jacking holes adapted to receive threaded fasteners for aiding in removal of said plate adapter from said coupling.

28. A plate adapter for rigidizing a flexible coupling half, said flexible coupling half including a hub adapted to be secured to a shaft of a rotating apparatus and a sleeve interconnected with said hub by means of a flexible disk pack, said plate adapter comprising:
-
a main body having a flexible pilot adapter to engage said hub in a press-fit relationship and to ensure a residual press-fit contact between said flexible pilot and said hub upon high speed rotation, and an annular flange extending from said main body; and
a pilot projecting from said annular flange extending radially from said main body, said pilot sized to form an interference fit between said main body and said sleeve;
wherein a mass distribution of the plate adapter results in an increase in said interference fit between said annular flange extending radially from said main body and said sleeve upon high speed rotation.
