Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
102 words
A floating power transmission ring gear system comprising in combination: a floating power transmission ring gear having an inner toothed periphery with a first pitch diameter, said inner periphery is meshed with and supported by a pinion gear having a second pitch diameter substantially smaller than said first pitch diameter, said ring gear has an outer periphery which is engaged with and supported by a belt means, the improvement wherein said ring gear is supported by said pinion gear through the gear mesh between them and serves to reduce the linear movement of said belt means per a revolution of said pinion.
Claim 2
Dependent Claim
102 words
A floating power transmission ring gear system comprising in combination: a floating power transmission ring gear having an inner toothed periphery with a first pitch diameter, said inner periphery is meshed with and supported by a pinion gear having a second pitch diameter substantially smaller than said first pitch diameter, said ring gear has an outer periphery which is engaged with and supported by a belt means, the improvement wherein said ring gear is supported by said pinion gear through the gear mesh between them and serves to reduce the linear movement of said belt means per a revolution of said pinion.
Claim 3
Dependent Claim
24 words
The subject matter of claim 1 wherein said gear mesh between said pinion and said ring gear is substantially wider than said belt means.
Claim 4
Dependent Claim
16 words
The subject matter of claim 1 wherein said ring gear is made of a plastic material.
Claim 5
Dependent Claim
26 words
The subject matter of claim 1 wherein said ring gear is elastic so that under load said ring gear assumes an offset position and becomes ovalized.
