Abstract
In a circular saw, a high speed motor has a housing attached to a casing by a mechanical coupling including bolts, circular sleeves, and end washers. A speed reduction gear-box includes first and second gears. The sleeve fits inside a circular channel. When the bolts are tightened, the casing is free to move, to some extent, relative to the housing, so the gear self-align and are much less noisy during use. This structure also enables less precise quality control for the manufacture of the relevant components of the saw.
