Abstract:
1. A wood lathe comprising: a bed; a headstock mounted on said bed and having a headstock housing; a motor mounted securely in said headstock housing and having two axial ends and an annular outer area that extends between said axial ends, said motor including a driving shaft with opposite first and second output ends that project outwardly and axially from said axial ends of said motor, respectively; a spindle rotatably journalled to said headstock housing and parallel to said driving shaft; a first transmission unit interconnecting said first output end of said driving shaft and said spindle so as to permit co-rotation of said spindle with said driving shaft; a cooling fan disposed in said headstock housing adjacent to said motor for cooling said motor, said cooling fan including a driven shaft that is rotatably journalled to said headstock housing and that is parallel to said driving shaft, a plurality of blades projecting outwardly from said driven shaft, and a fan casing coaxially surrounding said driven shaft and said blades, said fan casing having an axially extending peripheral wall that is formed with a first air outlet which is disposed adjacent to and which opens toward said annular outer area of said motor in a transverse direction relative to a rotation axis of said driven shaft so as to direct airflow toward said annular outer area of said motor upon rotation of said driven shaft; and a second transmission unit interconnecting said second output end of said driving shaft and said driven shaft so as to permit co-rotation of said driven shaft with said driving shaft.
