Independent Claim
57 words
Flywheel assembly with anti-cracking safeguard for protection against overspeed, comprising a frusto-conical shaft portion, a flywheel mounted in a press-fitting engagement on said shaft portion and having a force applied thereto directed toward the end of the frusto-conical shaft portion having the smaller diameter, and a catching and centering device for said flywheel located adjacent said flywheel.
Claim 2
Dependent Claim
57 words
Flywheel assembly with anti-cracking safeguard for protection against overspeed, comprising a frusto-conical shaft portion, a flywheel mounted in a press-fitting engagement on said shaft portion and having a force applied thereto directed toward the end of the frusto-conical shaft portion having the smaller diameter, and a catching and centering device for said flywheel located adjacent said flywheel.
Claim 3
Dependent Claim
42 words
The flywheel assembly according to claim 1 wherein said frusto-conical shaft portion is substantially vertically disposed, said end thereof of smaller diameter being located below the other end thereof, said force applied to said flywheel being the force of it own weight.
Claim 4
Dependent Claim
36 words
Flywheel assembly according to claim 1 including an outer pot-shaped container surrounding said flywheel and having a bottom, and a centering pot also surrounding said flywheel and supported on the bottom of said outer pot-shaped container.
Claim 5
Dependent Claim

Flywheel assembly according to claim 1 wherein said catching and centering device is rotatably mounted around said flywheel.
Claim 6
Dependent Claim
22 words
Flywheel assembly according to claim 4 including a springmounted slide plate, said catching and centering device being disposed on said slide plate.
Claim 7
Dependent Claim
61 words
Flywheel assembly according to claim 4 wherein said flywheel is releasable from the press-fitting engagement thereof with said frusto-conical shaft portion, said catching and centering device having conical engagement surfaces that are engageable with the outside of said flywheel when said flywheel is released from said press-fitting engagement thereof with said shaft portion, said conical engagement surfaces being formed with grooves.
Claim 8
Dependent Claim
58 words
Flywheel assembly according to claim 1, wherein said frusto-conical shaft portion is part of a driven shaft, and said catching and centering device comprises centering means connected to said flywheel and bearing on said driven shaft, and catching means disposed in the direction of the force applied to the flywheel and located in vicinity of said centering means.
Claim 9
Dependent Claim
71 words
Flywheel assembly according to claim 1, wherein said frusto-conical shaft portion has an end of larger diameter than the other end thereof, another shaft portion contiguous with said end of larger diameter and being formed with recesses, means coupled with said flywheel and projecting into said recesses so as to form a formlocking connection in tangential direction of said flywheel, said means projecting into said recesses being disposed axially displaceably therein.
Claim 10
Dependent Claim
47 words
Flywheel assembly according to claim 8 wherein said other shaft portion contiguous with the larger-diameter end of said frusto-conical shaft portion is larger in diameter than the largest diameter of said frusto-conical shaft portion, said recesses being formed in said other shaft portion extending in axial direction.
Claim 11
Dependent Claim
68 words
Flywheel assembly according to claim 8 wherein said means coupled with said flywheel and projecting into said recesses formed in said other shaft portion comprise a plurality of form bodies received in hollow openings defined by said recesses formed in said other shaft portion and by corresponding recesses formed in said flywheel and disposed adjoining and in registry with the respective recesses formed in said other shaft portion.
