Gear transmission

Claim 2

In a transmission including two gear trains having intermediate shafts driven by a single drive shaft through at least one respective transmission stage and carrying at least one pinion, respectively, meshing with a gear located between the two intermediate drive shafts each gear train being connectible to a machine driven by the transmission, means to make the meshing of the gear trAins to the driven machine self adjustable, comprising a pair of frames wherein the transmission stages are disposed, each of said frames being mounted on one of the intermediate shafts, and each being articulatingly connected on the other hand to the frame mounted on the other intermediate shaft, each of the frames being pivotally mounted and articulatingly connected about the drive shaft.

Claim 3

Transmission according to claim 1, wherein a respective pair of said frames that are connected to one another form an angle enclosed therebetween which deviates from 180*.

Claim 4

Transmission according to claim 1 including one common drive shaft, two pinions having teeth with opposing inclinations mounted on the common drive shaft, a gear wheel mounted on each of said intermediate shafts, and a gear wheel in each of said transmission stages associated with one of said intermediate shafts, respectively, each of said pinions being in meshing engagement with a gear on one of said intermediate shafts.

Claim 5

Transmission according to claim 3, wherein said drive shaft is mounted in said frames of said transmission stages of both said intermediate shafts.

Claim 6

Transmission according to claim 1, wherein said intermediate shafts are mounted in a bearing carrier, said frames of said transmission stages being pivotable with respect to said bearing carrier but being held against displacement in direction of the axes of said intermediate shafts.

Claim 7

In a transmission including two intermediate shafts driven by at least one drive shaft through at least one respective tranmission stage and carrying at least one pinion, respectively. meshing with a gear located between the two intermediate drive shafts and connectible to a machine driven by the transmission, the improvement which comprises a plurality of frames wherein the transmission stages are disposed, each of said frames being mounted on the one hand on one of the intermediate shafts, and being articulatingly connected on the other hand to the frame mounted on the other intermediate shaft, including one common drive shaft, two pinions having teeth with opposing inclinations mounted on the common drive shaft, a gear wheel mounted on each of said intermediate shafts, and a gear wheel in each of said transmission stages associated with one of said intermediate shafts, respectively, each of said pinions being in meshing engagement with a gear on one of said intermediate shafts, said drive shaft being mounted in said frames of said transmission stages of both said intermediate shafts, said frames having a mutual swivel joint connection therebetween, and wherein said drive shaft has an axis substantially coincident with the axis of said swivel joint connection.

Claim 8

In a transmission including two intermediate shafts driven by at least one drive shaft through at least one respective tranmission stage and carrying at least one pinion, respectively. meshing with a gear located between the two intermediate drive shafts and connectible to a machine driven by the transmission, the improvement which comprises a plurality of frames wherein the transmission stages are disposed, each of said frames being mounted on the one hand on one of the intermediate shafts, and being articulatingly connected on the other hand to the frame mounted on the other intermediate shaft, including one common drive shaft, two pinions having teeth with opposing inclinations mounted on the common drive shaft, a gear wheel mounted on each of said intermediate shafts, and a gear wheel in each of said transmission stages associated with one of said intermediate shafts, respectively, each of said pinions being in meshing engagement with a gear on one of said intermediate shafts, said drive shaft being mounted in said frames of said transmission stages of both said intermediate shafts, said frames having a mutual swivel joint connection therebetween, and wherein said drive shaft has an axis substantially coincident with the axis of said swivel joint connection.

Claim 9

In a transmission including two intermediate shafts driven by at least one drive shaft through at least one respective transmission stage and carrying at least one pinion, respectively, meshing with a gear located between the two intermediate drive shafts and connectible to a machine driven by the transmission, the improvement which comprises a plurality of frames wherein the transmission stages are disposed, each of said frames being mounted on the one hand on one of the intermediate shafts, and being articulatingly connected on the other hand to the frame mounted on the other intermediate shaft, a common pinion carrier supported so as to be movable in the manner of a ball-and-socket joint with respect to the base of the driven machine, said intermediate shafts being mounted in said common pinion carrier.

Claim 10

In a transmission including two intermediate shafts driven by at least one drive shaft through at least one respective transmission stage and carrying at least one pinion, respectively, meshing with a gear located between the two intermediate drive shafts and connectible to a machine driven by the transmission, the improvement which comprises a plurality of frames wherein the transmission stages are disposed, each of said frames being mounted on the one hand on one of the intermediate shafts, and being articulatingly connected on the other hand to the frame mounted on the other intermediate shaft, a common pinion carrier supported so as to be movable in the manner of a ball-and-socket joint with respect to the base of the driven machine, said intermediate shafts being mounted in said common pinion carrier.

Claim 11

Transmission according to claim 7, wherein said pinion carrier is supported on the driven machine base by at least two connecting rods extending in parallel to tangents to partial circle contact points between pinions mounted on said intermediate shafts, on the one hand, and the gear connected to the driven machine, on the other hand.
