Abstract
A wedge clutch assembly for power tools, drilling rigs and like machinery utilizing rotating drills. The wedge clutch assembly has a pinion shaft adapted in shape to support a pinion gear, a bronze clutch cup, an optional thrust bearing, and a steel wedge clutch spring washer retained by a fastener. Another embodiment of the wedge cup assembly is assembled on a modified motor shaft to include a bronze clutch cup adapted to accept a sprocket wheel and a steel wedge clutch spring washer retained by a fastener.
Claims19
A wedge clutch assembly, comprising:
- a pinion gear having a top surface and a bottom surface, said pinion gear defining a centrally disposed throughbore having a frustoconical configuration;
- a bronze clutch cup having a frustoconical configuration and defining a an upper aperture and a lower aperture, wherein the lower aperture is substantially larger than the upper aperture, said clutch cup being inserted within the throughbore of said pinion gear;
- a cylindrical pinion shaft including:
- an upper externally threaded neck extending through the throughbore and protruding from the top surface of said pinion gear;
- a frustoconical section adjacent said threaded neck, said frustoconical section being dimensioned to fit within said clutch cup;
- an increased diameter section depending from said frustoconical section and extending below the bottom surface of said pinion gear, said increased diameter section having a diameter substantially greater than the diameter of said upper neck;
- a gear section adjacent said increased diameter section;
- and
- a decreased diameter section having a diameter substantially less than the diameter of said increased diameter section and said gear section;
- a wedge clutch spring washer centrally disposed above the top surface of said pinion gear;
- a fastener threaded on said upper neck above said wedge spring washer for adjusting an applied torque to a drive shaft of a tool;
- and
- a thrust bearing disposed between said fastener and said pinion gear.
