Title:
HAND-HELD OSCILLATING SPINDLE SANDER
Document Type and Number:
WIPO Patent Application WO2001041972
Kind Code:
A9
Abstract:
A hand-held oscillating sander (10) includes a pair of toothed pulleys (410, 420) associated with the output shaft (50). The first pulley (410) is attached to the output shaft (50) for rotation with the output shaft (50). The second pulley (420) is rotatably disposed on the output shaft (50). The first and second pulleys (410, 420) have a different number of teeth. The second pulley (420) includes opposed camming surfaces (430, 440). A cam follower (500) is attached to and extends from the output shaft (50). A pair of toothed belts (310, 320) are respectively entrained around the first and second pulleys (410, 420) from a jackshaft (30) rotatable received in the housing (12). Upon rotation of the toothed belts (310, 320), both pulleys (410, 420) rotate, but at slightly different speeds. This slight difference in speeds causes the cam follower (500) to move along the opposed camming surfaces (430, 440) to create an oscillation effect for the output shaft (50). A dust recovery system (16) is associated with the base of the tool.
