Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
58 words
In a differential gear assembly, the combination of an eccentrically weighted casing enclosing opposed bevel gears on a common axis and a differential gearing mechanism coupling said bevel gears, said mechanism comprising not less than three pinion gears asymmetrically arranged about said axis in counterbalancing relation with said casing, and shaft means supporting said pinion gears so disposed.
Claim 2
Dependent Claim
58 words
In a differential gear assembly, the combination of an eccentrically weighted casing enclosing opposed bevel gears on a common axis and a differential gearing mechanism coupling said bevel gears, said mechanism comprising not less than three pinion gears asymmetrically arranged about said axis in counterbalancing relation with said casing, and shaft means supporting said pinion gears so disposed.
Claim 3
Dependent Claim
17 words
The combination according to claim 1, in which said shaft means is supported endwise by the casing.
Claim 4
Dependent Claim
54 words
The combination according to claim 1, in which said shaft means includes a first shaft journaling two of said pinion gears and a second shaft angularly disposed relative to the first shaft and supporting another of said pinion gears, said first and second shafts lying in a common plane and asymmetrically about said axis.
Claim 5
Dependent Claim
21 words
The combination according to claim 3, including also means interengaging said first and second shafts in pinion gear asymmetry defining relation.
Claim 6
Dependent Claim
36 words
The combination according to claim 4 in which said interengaging means comprises a reduced diameter second shaft terminal portion, and means formed on said first shaft intermediate its ends to engage the second shaft terminal portion.
Claim 7
Dependent Claim
23 words
The combination according to claim 5 in which said first shaft is provided with a bore sized to receive said second shaft portion.
Claim 8
Dependent Claim
42 words
The combination according to claim 5, in which said first shaft is supported at its opposite ends by said casing and said second shaft is endwise supported by said casing opposite the locus of second shaft portion engagement with said first shaft.
Claim 9
Dependent Claim
23 words
The combination according to claim 7 in which said second shaft is at an angle of about 79° relative to said first shaft.
Claim 10
Dependent Claim
19 words
The combination according to claim 7 in which said second shaft is at right angles to said first shaft.
Claim 11
Dependent Claim
22 words
The combination according to claim 4 in which said interengaging means comprises a block interfitting said shafts in their defined asymmetric relation.
Claim 12
Dependent Claim
23 words
The combination according to claim 10 in which said second shaft is at an angle of approximately 79° relative to said first shaft.
Claim 13
Dependent Claim
19 words
The combination according to claim 10 in which said second shaft is at right angles to said first shaft.
Claim 14
Dependent Claim
59 words
The combination according to claim 1, in which said shaft means includes a first shaft journaling opposed first and second pinion gears, a second shaft journaling a third pinion gear, and a third shaft journaling a fourth pinion gear; said first, second, and third shafts lying in a common plane and relatively disposed in asymmetric relation about said axis.
Claim 15
Dependent Claim
22 words
The combination according to claim 13 including also means interengaging said first, second and third shafts in pinion gear asymmetry defining relation.
Claim 16
Dependent Claim
41 words
The combination according to claim 14, in which said first shaft is supported at its opposite ends by said casing, and said second and third shafts are supported endwise by said casing opposite their locus of engagement with the interengaging means.
Claim 17
Dependent Claim
21 words
The combination according to claim 15, in which said interengaging means comprises a block interfitting said shafts in their asymmetric relation.
Claim 18
Dependent Claim
25 words
The combination according to claim 16, in which said block is mounted on said first shaft and apertured to receive said second and third shafts.
Claim 19
Dependent Claim
28 words
