Blade driving mechanism for a table saw

Abstract

The present invention provides a blade driving mechanism for a table saw, wherein the table saw comprises a main frame and a saw blade mounted to and driven by the blade driving mechanism, and the blade driving mechanism comprises an electrical motor mounted to the main frame, with the motor being capable of sliding with respect to the main frame; a belt driving system for transferring the rotation of an output shaft of the motor to the saw blade; a center-distance setting means connected between the motor and the saw blade, for adjustably setting the center-to-center distance between the motor and the saw blade; and a saw-blade height adjusting device being operable to adjust the height of the of the saw blade. saw-blade height adjusting device comprises a transverse shaft being capable of rotating about a horizontal axis; a handwheel fixed to the outer end of the transverse shaft for driving the transverse shaft to rotate; a vertical screw shaft coupled with the transverse shaft by a set of bevel gears and is driven by the transverse shaft to rotate about a vertical axis; a nut mounted on and engaged with the screw shaft and being capable of moving along the screw shaft by the rotation of the screw shaft; and a guide connected to the nut and supporting the saw blade.
