Abstract
In one embodiment, a table saw assembly includes a motor assembly, an electrically conductive belt operably connected to the motor assembly, an arbor shaft operably connected to the belt, a drop arm assembly rotatably supporting the arbor shaft, a first pulley rotatably supporting the belt, the first pulley including an inner component defining an inner bore and an outer component defining an outer surface, the first pulley configured to electrically isolate the inner bore from the outer surface, and an alignment adjustment mechanism operably connected to the first pulley, the alignment adjustment mechanism configured to selectably position the first pulley along an axis of rotation of the first pulley.
Claims7
A table saw assembly comprising:
- a motor assembly;
- an electrically conductive belt operably connected to the motor assembly;
- an arbor shaft operably connected to the belt;
- a drop arm assembly rotatably supporting the arbor shaft;
- a first pulley rotatably supporting the belt, the first pulley including an inner component defining an inner bore and an outer component defining an outer surface, the first pulley configured to electrically isolate the inner bore from the outer surface;
- and
- an alignment adjustment mechanism operably connected to the first pulley, the alignment adjustment mechanism selected to compensate for tolerance build up associated with the first pulley so as to selectably position the first pulley along an axis of rotation of the first pulley;
- wherein the first pulley is fixedly attached to a drive shaft of the motor assembly.
