Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
In a flexible all-steel shaft coupling comprising a connecting flange for each coupling half, a yieldable stapled lamella crown having bore holes and located in an axially spaced relationship between the connecting flanges, and alternately connected in a circumferential direction by clamp bolts to one or the other of the connecting flanges, wherein the bore holes of the stapled lamella crown are seated on spring collets having tap holes therethrough and the lamella crown clamped between spacer rings by the clamp bolts which extend through the top holes, the improvement comprising means for effecting radial expansion of the spring collets in response to axial tension by the clamp bolts comprising to subject the lamella crown to both axial pretension and to radial pretension at the spring collets.
Claim 2
Dependent Claim
127 words
In a flexible all-steel shaft coupling comprising a connecting flange for each coupling half, a yieldable stapled lamella crown having bore holes and located in an axially spaced relationship between the connecting flanges, and alternately connected in a circumferential direction by clamp bolts to one or the other of the connecting flanges, wherein the bore holes of the stapled lamella crown are seated on spring collets having tap holes therethrough and the lamella crown clamped between spacer rings by the clamp bolts which extend through the top holes, the improvement comprising means for effecting radial expansion of the spring collets in response to axial tension by the clamp bolts comprising to subject the lamella crown to both axial pretension and to radial pretension at the spring collets.
Claim 3
Dependent Claim
61 words
The coupling according to claim 1, wherein the radial expanding means comprises the tap holes of each spring collet and each bolt having a conical shape and wherein the lamella crown and spring collets are configured to effect contact of the lamella crown by the spring collets in response to increased axial tension force by each bolt in each tap hole.
Claim 4
Dependent Claim
22 words
The coupling according to claim 2, wherein each flange has holes for receiving the bolts and wherein the flange holes are conical.
Claim 5
Dependent Claim
15 words
The coupling according to claim 3, wherein the flange holes have separate spring collets therein.
Claim 6
Dependent Claim
45 words
The coupling according to claim 2, wherein each flange has cylindrical holes for receiving the bolts and wherein the spring collets have portions extending into the flange holes and having a tap hole having the same conical inclination as the remainder of the spring collet.
Claim 7
Dependent Claim
48 words
The coupling according to claim 2, wherein each flange has holes for receiving the bolts and the flange holes and the lamella crown bores lie in a circle and wherein the circle of the flange holes has a larger diameter than the circle of the lamella crown bores.
Claim 8
Dependent Claim
16 words
The coupling according to claim 1, wherein one spacer ring is integral with each spring collet.
