Sprocket wear indicator
First Claim
1. A sprocket comprised of a body with opposite side surfaces and a series of equally spaced teeth about an outer surface thereof between the side surfaces, each tooth comprising a tip with opposite flanks extending radially from said tip toward a root to define a tooth profile, and an indicator provided on at least one of said side surfaces at a predetermined distance from a relatively wornless tooth profile of least one of said sprocket teeth to provide a visual indication of wear of the sprocket teeth.

Abstract
A wear indicator for a sprocket adapted to have an endless track arranged in driving association therewith. The sprocket has opposite side surfaces and a series of sprocket teeth disposed peripherally about the sprocket. Each sprocket tooth has a tip with track engaging surfaces extending away therefrom to define a tooth profile. The sprocket wear indicator includes a visual marker on a side surface of the sprocket for allowing a person to visually gauge wear of the tooth profile on the sprocket.

- 1. A sprocket comprised of a body with opposite side surfaces and a series of equally spaced teeth about an outer surface thereof between the side surfaces, each tooth comprising a tip with opposite flanks extending radially from said tip toward a root to define a tooth profile, and an indicator provided on at least one of said side surfaces at a predetermined distance from a relatively wornless tooth profile of least one of said sprocket teeth to provide a visual indication of wear of the sprocket teeth.
- 3. A sprocket for an implement with an endless track adapted for driving association with said sprocket, said sprocket having an axis of rotation, opposite side surfaces, and a series of teeth disposed peripherally about said sprocket in equally spaced relation about said axis of rotation, each sprocket tooth having a tip and track contacting surfaces extending between tips of adjacent sprocket teeth, said sprocket further including a visual marker on a side surface of said sprocket for allowing a person to visually gauge wear of the track contacting surfaces of the toothed sprocket.
- 7. A sprocket for an implement with an endless track entrained in driving engagement with said sprocket, said endless track including a plurality of like sections articulately interconnected to each other by trackpins and bushings, said sprocket having opposite side faces and circumferentially adjacent teeth arranged to engage said bushings of said track whereby driving the track, each sprocket tooth having a tip with track engaging surfaces extending away therefrom to define a tooth profile, and wherein said sprocket further includes a wear indicator on a side surface thereof for visually indicating sprocket tooth wear, said wear indicator including a visual marker disposed a predetermined distance inwardly from the tooth profile of at least one sprocket tooth to indicate that replacement of the sprocket is required when the tooth profile is worn proximate to the marker.
