Brake drum manufacture |
摘要 |
Manufacture of brake drums having an annular brake ring and a drum back for mounting the ring for rotation about an axis defined at least in part by one or more openings in the back. Radial runout of the brake ring is measured, and the mounting openings in the drum back are located at a position to substantially cancel the first harmonic of measured radial runout. The radially inwardly directed braking surface of the drum ring is then finish-machined on a cylinder of revolution coaxial with the drum back mounting openings so as to provide a brake ring of substantially uniform thickness and weight distribution about the axis of rotation defined by the drum back mounting openings.
