Abstract
A drive assembly for a mining machine. The drive assembly includes one-and-only-one sprocket and a housing coupled to the mining machine. The housing includes a shoe and at least partially receives the sprocket. The drive assembly also includes a motor and a drive shaft that couples the sprocket and the motor. The drive shaft rotates the sprocket and defines a longitudinal axis. The housing rotates relative to the mining machine about the longitudinal axis and in a face-to-gob direction.
