Abstract
Abstract A gear arrangement, wherein a first pair of spur gears, concentric and rigidly connected for simultaneous rotation are in driving relation with a second pair of intermeshing gears similarly arranged, is rendered more effective in the smooth transfer of power by indexing the teeth of one of the concentric gears in at least one pair relative to the other of the concentric gears in the same pair by an amount between one-half of the circular pitch and full registration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A gear complex arrangement for efficient and smooth transfer of power to a coacting meshing gear complex arrangement, comprising a pair of spur gears on one complex mutually intermeshing respectively with a pair of spur gears on the other complex, said gears of each complex mounted concentric and in longitudinally spaced relation on a common shaft and both rotatable therewith, and with the teeth of intermeshing gears at one end of said complexes in a synclinal relationship with the teeth at the other end of said complexes nearest longitudinal alignment with said first named teeth, such that the teeth of one gear of said pair on the same complex are indexed relative to the teeth of the other gear of said pair nearest longitudinal alignment by an amount greater than a normal manufacturing tolerance and avoiding a relative position at one-half of the circular pitch and one in full registration, whereby the teeth of only one of said pair of gears is in full mesh with its coacting gear at any given time.
Claim 2
Dependent Claim
173 words
A gear complex arrangement for efficient and smooth transfer of power to a coacting meshing gear complex arrangement, comprising a pair of spur gears on one complex mutually intermeshing respectively with a pair of spur gears on the other complex, said gears of each complex mounted concentric and in longitudinally spaced relation on a common shaft and both rotatable therewith, and with the teeth of intermeshing gears at one end of said complexes in a synclinal relationship with the teeth at the other end of said complexes nearest longitudinal alignment with said first named teeth, such that the teeth of one gear of said pair on the same complex are indexed relative to the teeth of the other gear of said pair nearest longitudinal alignment by an amount greater than a normal manufacturing tolerance and avoiding a relative position at one-half of the circular pitch and one in full registration, whereby the teeth of only one of said pair of gears is in full mesh with its coacting gear at any given time.
Claim 3
Dependent Claim
22 words
A gear arrangement as defined in claim 1, wherein said two spur gears of said pair have the same number of teeth.
Claim 4
Dependent Claim
42 words
A gear arrangement as defined in claim 1, wherein said indexing of the teeth of said one of said pair of gears relative to the teeth of the said other of said pair of gears is greater than five-thousandths of an inch.
Claim 5
Dependent Claim
20 words
A gear arrangement as defined in claim 1, wherein said gears of said pair have less than 20 teeth each.
Claim 6
Dependent Claim
42 words
A gear arrangement as defined in claim 1, wherein said indexing of the teeth of said one of said pair of gears relative to the teeth of the said other of said pair of gears is about one-fourth of the circular pitch.
