DUAL STAGE DRIVE FOR POWER EQUIPMENT

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.

1. A power equipment comprising:
a base defining an enclosure space; a table supported on the base above the enclosure space and including a blade opening; and a cutting assembly supported within the enclosure space below the table, the cutting assembly including a motor having an output shaft, a dual stage drive system operably coupled to the output shaft, and an arbor operably coupled to the dual stage drive system, the arbor being configured to retain a cutting blade with the cutting blade extending upwardly from the enclosure space through the blade opening in the table, wherein the output shaft defines a first axis of rotation, wherein the dual stage drive system includes:
a first pinion mounted on the output shaft for rotation about the first axis,a first gear positioned in meshing engagement with the first pinion, the first gear being mounted on a first shaft, the first shaft defining a second axis of rotation that is substantially parallel to the first axis and being positioned such that the second axis is offset from the first axis,a second pinion mounted on the first shaft for rotation about the second axis,a second gear positioned in meshing engagement with the second pinion, the second gear being mounted on a second shaft, the second shaft defining a third axis of rotation that is substantially parallel to the second axis and being positioned such that the third axis is offset from the first axis and the second axis, wherein the arbor is connected to the second shaft for rotation about the third axis along with the second shaft.
