The purpose of this paper is to reduce the manufacturing cost of the ball mill gear transmission as much as possible to minimize the volume while maximizing reliability. The volume is calculated as (42) V = π 4 b d 1 2 + d 2 2 = π 4 b m n z 1 cos β 2 + m n z 2 cos β 2 and makes F 1 = V/V max. The ball mill gear transmission failure rate is ...
