Abstract
Abstract A monitoring wheel is disclosed for monitoring the movement of a rotary device. The monitoring wheel utilizes a commercially available nonmagnetic precision gear having a mixture of metallic material and a bonding agent compacted within the space between the gear teeth. The mixture within the gear is then machined to approximately the pitch line to enable a plurality of evenly spaced pulse indicators to be formed about the periphery of the gear.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
A monitoring wheel for monitoring the movement of a rotary device comprising: a gear of nonmagnetic material having a plurality of radially extending teeth peripherally spaced about the circumference thereof, each gear tooth being defined by a top wall portion and a pair of sidewalls which slope downwardly and outwardly from said top wall, said gear further defining a pocket between the sidewalls of each pair of adjoining gear teeth; and a quantity of maGnetic composition compacted within the pockets formed between the gear teeth thereby forming a plurality of pulse indicators located intermittently about the periphery of the gear, the top of each of said pulse indicators includes an outer arcuate surface substantially approximating the curvature of the gear, the band width of each arcuate surface progressively diminishing as the depth of the pulse indicator decreases.
Claim 2
Dependent Claim
137 words
A monitoring wheel for monitoring the movement of a rotary device comprising: a gear of nonmagnetic material having a plurality of radially extending teeth peripherally spaced about the circumference thereof, each gear tooth being defined by a top wall portion and a pair of sidewalls which slope downwardly and outwardly from said top wall, said gear further defining a pocket between the sidewalls of each pair of adjoining gear teeth; and a quantity of maGnetic composition compacted within the pockets formed between the gear teeth thereby forming a plurality of pulse indicators located intermittently about the periphery of the gear, the top of each of said pulse indicators includes an outer arcuate surface substantially approximating the curvature of the gear, the band width of each arcuate surface progressively diminishing as the depth of the pulse indicator decreases.
Claim 3
Dependent Claim
27 words
The invention of claim 1 wherein said arcuate surfaces are located on the pitch line with the outer surfaces of the gear teeth being intermittently spaced therebetween.
Claim 4
Dependent Claim
29 words
The invention of claim 1 wherein said arcuate surfaces are located above the pitch line to form relatively wider band pulse indicators extending about the periphery of the gear.
Claim 5
Dependent Claim
29 words
The invention of claim 1 wherein said arcuate surfaces are located below the pitch line to form relatively narrower band pulse indicators extending about the periphery of the gear.
Claim 6
Dependent Claim
23 words
The invention of claim 1 wherein said quantity of magnetic composition is formed from a mixture of metallic powder and a bonding agent.
Claim 7
Dependent Claim
13 words
The invention of claim 1 wherein said gear is made of nonferrous metal.
