Abstract
Abstract In a centrifugal governor a primary or driving part is connected for torque transmission to a secondary or driven part by means of elastic coupling elements. The primary part comprises a drive shaft and a bowl-shaped housing affixed thereto, while the secondary part comprises a centrifugal weight carrier received in said housing. An internal cylindrical wall portion of the housing constitutes the external bearing for the centrifugal weight carrier. A peripheral cylindrical face of the centrifugal weight carrier cooperates with the internal cylindrical wall portion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
In an elastic rotary coupling between a drive shaft and a centrifugal weight carrier of a centrifugal governor, said elastic rotary coupling being of the type that has (a) a primary or driving part affixed to said drive shaft, (b) a secondary or driven part including said centrifugal weight carrier, (c) a cage formed jointly by said driving and said driven parts, (d) elastic coupling elements disposed in said cage symmetrically with respect to said drive shaft, said elastic coupling elements transmitting the torque from said primary part to said secondary part, the improvement comprising a bowl-shaped housing forming part of said primary part and being secured to said drive shaft, said centrifugal weight carrier being received in said bowlshaped housing, said bowl-shaped housing having a wall portion including an inner cylindrical running face, said inner cylindrical running face constituting an external bearing for said centrifugal weight carrier.
Claim 2
Dependent Claim
148 words
In an elastic rotary coupling between a drive shaft and a centrifugal weight carrier of a centrifugal governor, said elastic rotary coupling being of the type that has (a) a primary or driving part affixed to said drive shaft, (b) a secondary or driven part including said centrifugal weight carrier, (c) a cage formed jointly by said driving and said driven parts, (d) elastic coupling elements disposed in said cage symmetrically with respect to said drive shaft, said elastic coupling elements transmitting the torque from said primary part to said secondary part, the improvement comprising a bowl-shaped housing forming part of said primary part and being secured to said drive shaft, said centrifugal weight carrier being received in said bowlshaped housing, said bowl-shaped housing having a wall portion including an inner cylindrical running face, said inner cylindrical running face constituting an external bearing for said centrifugal weight carrier.
Claim 3
Dependent Claim
30 words
An improvement as defined in claim 1, wherein said cage is axially bounded on one side by said bowl-shaped housing and on the other side by said centrifugal weight carrier.
Claim 4
Dependent Claim
96 words
An improvement as defined in claim 1, including A. an outer drive disc or ring radially bounding said cage and having first driving lugs extending radially inwardly into said cage and B. an inner drive disc or ring radially bounding said cage and having second driving lugs extending radially outwardly into said cage, one of said driving rings forming part of said primary part and the other of said driving rings forming part of said secondary part, each said elastic coupling element being compressed between and laterally engaged by a first and a second driving lug.
Claim 5
Dependent Claim
56 words
An improvement as defined in claim 3, including A. a tightening nut threadedly mounted on said drive shaft and B. a closure disc inserted on said drive shaft; said bowl-shaped housing, said inner and outer driving rings and said centrifugal weight carrier being held together on said drive shaft by said nut through said closure disc.
