ABSTRACT:
A guide sprocket assembly for use in combination with a non-driven, rotating tail shaft. The guide sprocket assembly includes a lock plate assembly securely fixed to the tail shaft for rotation along with the tail shaft. The lock plate assembly includes an annular sprocket groove that receives an annular guide sprocket having a plurality of projecting teeth spaced along its outer circumference. The guide sprocket is retained within the annular sprocket groove by a sprocket retainer. The combination of the guide sprocket and sprocket retainer are freely rotatable within the annular sprocket groove relative to the lock plate assembly. The teeth of the guide sprocket engage a drive chain, and the guide sprocket can rotate either in the direction of rotation of the tail shaft or in an opposite direction to properly align the individual links of the drive chain with the teeth formed on the guide sprocket.
