a specific example, a 6,250kW ball mill gear at output speed has a required rim thickness value of 210mm ( in) in a tee configuration whereas the box Y gear has 165mm ( in). This reduces the overall weight of the gear to 61,600 kg (135,700 lbs.) in a box Y configuration but 67,500 kg (148,700 lbs.) as a tee configuration.

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 ...
