Abstract
An improved method for final balancing the brake drum determines the location and length of a constant depth cut along the squealer band which is necessary to correct the imbalance, and using a cutting machine, makes the constant depth cut at the predetermined location and for the predetermined length along the squealer band to produce a final balanced brake drum. Preferably, the cutting machine is a milling machine which produces a plunge type entrance/exit cut. It is a further feature of the invention to provide a feather type entrance/exit cut to reduce the stress concentrations, and produce a cosmetically more appealing final balanced brake drum.
Claims4
A final balanced brake drum comprising a generally cylindrical body provided with an integral raised squealer band, said squealer band having an outwardly facing surface initially machined to a predetermined diameter around its entire circumference, said brake drum having the initially machined squealer band incorporating an unacceptable imbalance, said squealer band being further machined to produce a cut at a predetermined location along said squealer band, said cut having a circumferentially extending substantially constant depth which extends along a predetermined length of said squealer band, with said predetermined location, depth, and length being selected to produce a brake drum which corrects the imbalance.
