摘要： This invention provides a new and more efficient drive system for a circular saw blade. The invention is comprised of a circular saw blade with a ring gear built into the blade. It is driven by a matching pinion gear. The invention provides a means to employ the typical cutting capabilities of a circular saw blade but with certain unique advantages. The ring and pinion drive allows for better balance in that the motor that drives the saw blade can be located at the rear of the saw blade, as opposed to the side of the blade as it is with conventional circular saws. This configuration also allows for greater cutting depth. The ring and pinion drive also allows for a smaller motor and a resulting lower cutting speed that, in turn, cuts down on dust emission.
