Abstract
Abstract A diamond hone for re-working and correcting lead and involute profile of hardened gears which is characterized by a monolayer of diamond abrasive bonded to a gear hone which is provided with a unique geometry wherein the tip and pitch diameter portions are specifically formed to obtain a predetermined deviation from the true involute form conventionally employed. This new diamond hone and unique geometry imparts the desirable final geometry in the re-worked gear.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
In a gear honing tool the combination of a gear-like blank member provided with a plurality of teeth generally adapted to mesh with the teeth of the gear being worked and a monolayer of diamond crystals bonded to the hone teeth to form an abrasive surface, each of said hone teeth carrying said layer of diamond crystals having a predetermined profile configuration having a negative deviation from the true involute form defining a relatively smooth curve having a substantially concave shape.
Claim 2
Dependent Claim
81 words
In a gear honing tool the combination of a gear-like blank member provided with a plurality of teeth generally adapted to mesh with the teeth of the gear being worked and a monolayer of diamond crystals bonded to the hone teeth to form an abrasive surface, each of said hone teeth carrying said layer of diamond crystals having a predetermined profile configuration having a negative deviation from the true involute form defining a relatively smooth curve having a substantially concave shape.
Claim 3
Dependent Claim
18 words
The tool defined in claim 1 wherein said tip portion is negative relative to the true involute shape.
Claim 4
Dependent Claim
40 words
The tool defined in claim 1 wherein said profile deviation defines a relatively smooth curve from the start of the active profile to the tip of the hone tooth with the greatest negative deviation occurring at approximately the pitch diameter.
Claim 5
Dependent Claim
21 words
The hone defined in claim 1 wherein the negative deviation at the pitch diameter ranges from approximately 0.0005 to 0.002 inches.
Claim 6
Dependent Claim
20 words
The tool defined in claim 1 wherein said tool includes diamond crystal sizes ranging from approximately 100 to 400 mesh.
