摘要： A power equipment includes a base defining an enclosure space, a table supported on the base, and a cutting assembly supported within the enclosure space below the table. The cutting assembly includes a motor having an output shaft and a dual stage drive system operably coupled to the output shaft. The output shaft defines a first axis of rotation. The dual stage drive system includes a first pinion mounted on the output shaft for rotation about the first axis, a first gear meshed with the first pinion and mounted on a first shaft that defines a second axis of rotation that is offset from the first axis, a second pinion mounted on the first shaft for rotation about the second axis, and a second gear meshed with the second pinion and mounted on a second shaft that defines a third axis of rotation. An arbor is connected to the second shaft for rotation about the third axis along with the second shaft. The first shaft is offset below the second shaft, and the output shaft is offset below the first shaft.

摘要： A safety system is provided for a power tool having a motor-driven cutting blade, a safety mechanism operable by a controller to stop and/or move the cutting blade and a blade guard. The safety system includes an electrically active surface provided on the blade guard that is configured to change an electrical characteristic in response to contact between the body of an operator and the active surface. An active surface controller is operable to provide electrical power to the electrically active surface, to generate a signal in response to the change in the electrical characteristic, the signal indicative of an unsafe condition, and to transmit the signal to the controller for the safety mechanism.

摘要： A guide assembly for aligning a workpiece on a table of a saw device includes a guide member having a first end and a second end along the longitudinal axis that is sized to span a dimension of the table. The guide member includes first and second locking mechanisms located at opposite ends of the guide member that are operable to secure the guide member to the table. The guide assembly further includes a fine adjustment mechanism incorporated into the guide member that is operable when the first and second locking mechanisms are locked. The adjustment assembly includes a side plate movably mounted to the guide member between the first and second ends, and a movement mechanism for moving the side plate relative to the guide member in a direction perpendicular to the longitudinal axis.

摘要： A table saw includes a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by the base assembly. The saw assembly has a motor having a motor output shaft and a power train assembly. The motor is configured to rotate the motor output shaft at a first rotational speed. The power train assembly includes an intermediate shaft, a first gear stage, an arbor shaft, and a second gear stage. The first gear stage is configured to transmit rotation of the motor output shaft at the first rotational speed to rotation of the intermediate shaft at a second rotational speed, which is less than the first rotational speed. The second gear stage is configured to transmit rotation of the intermediate shaft at the second rotational speed to rotation of the arbor shaft at a third rotational speed, which is greater than the second rotational speed.

摘要： A table saw includes a support arrangement and a table top assembly including a work piece support surface defining a plane and a saw blade opening in the work piece support surface. An undercarriage assembly, mounted to the table top assembly, supports a saw blade in an adjustable angular position and includes a motor assembly and an arbor shaft to support the saw blade in the saw blade opening. The bevel pivoting mechanism is configured to increase a distance between the motor or arbor shaft and the plane of the work piece support surface with a change to the angular position of the saw blade to substantially prevent the motor or arbor from contacting the table top assembly.

摘要： A sliding table assembly for a main table of a saw machine includes a sliding table member having a planar upper surface, a miter slot, and a rail structure, and a bracket structure configured to be attached to a mounting structure on the main table of the table saw. The bracket structure is configured to squeeze the rail structure to provide zero clearance support for slidably retaining the sliding table member. Vertical and horizontal position adjustment mechanisms are operably connected to the bracket structure and configured to move at least a portion of the bracket structure horizontally as well as vertically with respect to the mounting structure to align the upper surface of the sliding table member in plane with the upper surface of the main table and to align the miter slot parallel to a blade of the saw machine.
