Abstract
Abstract A coupling flange on a torque transmitting shaft or the like for coupling in face-to-face relationship with a counter-flange has at least two tooth systems on its coupling surface and each system comprising a plurality of substantially parallel axially projecting teeth having inclined flanks. At least one tooth in each tooth system has a different height, spacing or shape from the other teeth in the tooth system and the tooth systems are engagable with a complementary configuration on the counter-flange so as to connect nonrotatably the flanges.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
A flange, particularly on a torque transmitting shaft or the like, for rigidly but detachably coupling to a counter-flange and comprising a coupling plate having a coupling surface engagable face-to-face with a counter-coupling flange and there being a plurality of openings through said coupling plate to receive detachable fastener elements, said coupling surface having two tooth systems thereon each comprising a plurality of substantially parallel axially projecting teeth having inclined flanks, at least one tooth in each tooth system having one of a different height, spacing and shape from the other teeth in said system and said tooth systems are engagable with a complementary configuration on a counter-flange to connect nonrotatably the flanges.
Claim 2
Dependent Claim
113 words
A flange, particularly on a torque transmitting shaft or the like, for rigidly but detachably coupling to a counter-flange and comprising a coupling plate having a coupling surface engagable face-to-face with a counter-coupling flange and there being a plurality of openings through said coupling plate to receive detachable fastener elements, said coupling surface having two tooth systems thereon each comprising a plurality of substantially parallel axially projecting teeth having inclined flanks, at least one tooth in each tooth system having one of a different height, spacing and shape from the other teeth in said system and said tooth systems are engagable with a complementary configuration on a counter-flange to connect nonrotatably the flanges.
Claim 3
Dependent Claim
23 words
A flange as claimed in claim 1 wherein at least one tooth in each tooth system has both a different height and spacing.
Claim 4
Dependent Claim
29 words
A flange as claimed in claim 1 wherein the teeth of one tooth system define an angle with the teeth of the other tooth system on said coupling flange.
Claim 5
Dependent Claim
14 words
A flange as claimed in claim 3 wherein said angle is a right angle.
Claim 6
Dependent Claim
14 words
A flange as claimed in claim 3 wherein said angle is less than 90°.
Claim 7
Dependent Claim
22 words
A flange as claimed in claim 5 wherein the teeth of one tooth system intersect the teeth of the other tooth system.
