Miter Saw

Abstract

The miter saw includes a base assembly, a rotatable table rotatably connected to the base assembly and having a plane, a saw assembly including a motor and a blade disposed on an arbor, and a pivot arm pivotally attached to the table and supporting the saw assembly. The motor preferably drives a belt, which drives a first gear. The first gear meshes with an idler gear, which in turn meshes with a gear disposed on the arbor.

       25 : A miter saw comprising: 
 a base assembly;    a rotatable table rotatably connected to the base assembly and having a table plane;    a saw assembly pivotable about a chopping axis, the saw assembly including a motor with a motor shaft, and a blade having a radius and being disposed on an arbor, the arbor having a first portion carrying the blade, a second portion disposed away from the blade, and a first gear disposed on the second portion, an intermediate gear meshing with the first gear, and a second gear driven by the motor and meshing with the intermediate gear, the second gear being driven by the motor via a belt and being above a line drawn between the motor shaft and the arbor; and    a pivot arm pivotally attached to the table and supporting the saw assembly, the pivot arm and saw assembly being pivotable about a horizontal bevel axis from a first position where the blade is substantially perpendicular to the table to a second position where the blade is disposed at an angle relative to the table, the angle between the blade and the table being about 45 degrees.    
   
   
       26 : The miter saw of  claim 25 , wherein a distance between the second portion and at least one of the base assembly and the table is smaller than a distance between the first portion and the at least one of the base assembly and the table when the saw assembly is in the second position.  
   
   
       27 : The miter saw of  claim 25 , wherein a distance between the chopping axis and the table plane being at least about 0.79 times the radius of the blade, and a distance between the arbor and the table plane when the saw assembly is in a lowered position is between about 0.671 and about 0.6775 times the radius of the blade.  
   
   
       27 : The miter saw of  claim 25 , wherein the intermediate gear is always meshing with the first and second gears.  
   
   
       28 : The miter saw of  claim 25 , wherein the distance between the chopping axis and the table plane is between about 11.98 cm and about 12.25 cm.  
   
   
       29 : The miter saw of  claim 25 , wherein the distance between the arbor and the table plane when the saw assembly is in the lowered position is between about 10.17 cm and about 10.38 cm.  
   
   
       30 : The miter saw of  claim 25 , further comprising a substantially vertical fence attached to the base, the fence having a fence plane.  
   
   
       31 : The miter saw of  claim 30 , wherein a distance between the chopping axis and the fence plane is between about 1.28 and about 1.292 times the radius of the blade, and a distance between the arbor and the fence plane when the saw assembly is in a lowered position is between about 0.60 and about 0.61 times the radius of the blade.  
   
   
       32 : The miter saw of  claim 31 , wherein the distance between the chopping axis and the fence plane is between about 19.40 cm and about 19.80 cm.  
   
   
       33 : The miter saw of  claim 31 , wherein the distance between the arbor and the fence plane when the saw assembly is in the lowered position is between about 9.10 cm and about 9.35 cm.
