Abstract
A circular saw shaft for cutting wood comprises a motor-driven shaft and a ircular saw blade mounted on the shaft. A support disk is mounted on the shaft in spaced relationship to the saw blade to apply to the wood a supporting force in a direction extending parallel to the axis of rotation of the shaft. The support disk can be fixed to the shaft, or biased along the shaft axis by springs. In lieu of springs, the support disk could be elastically flexible.
Claims15
A circular saw for cutting wood, comprising:
- a motor-driven saw shaft rotatably driven about an axis of rotation,
- a circular saw blade mounted on said saw shaft for rotation therewith to cut the wood in response to relative movement between the wood and saw blade in a first direction oriented transversely of said axis of rotation, and
- a support disk mounted coaxially on said shaft in spaced relationship to said saw blade, said support disk including support surface means facing said saw blade for applying to the wood a supporting force in a second direction extending towards said saw blade and transversely of said first direction.
