Abstract
A two-piece locking nut which includes a first nut (22) having an internal thread and a frusto-conical surface (32) at one end of said first nut, a second nut (28) having an internal thread of opposite hand as the thread of said first nut and a frusto-conical surface (36) at an end of said second nut which is complimentary to and positioned adjacent said frusto-conical surface of said first nut to prevent relative movement therebetween, and the second axial end (38) of the first nut opposite the frusto-conical surface (32) is positioned adjacent a workpiece to prevent axial displacement thereof.
Claims17
A locking nut to prevent axial displacement of a workpiece, comprising:
- a first nut having a first internal thread, a frusto-conical cavity at a first axial end of said first nut, a second surface at a second axial end of said first nut, wherein said second surface of said first nut is positioned adjacent the workpiece to prevent axial displacement thereof;
- a second nut having a second internal thread of opposite hand as said first thread of said first nut, a second frusto-conical surface at an axial end of said second nut, wherein said second frusto-conical surface of said second nut is complimentary to and positioned adjacent said cavity of said first nut to prevent relative movement therebetween.
A locking nut to prevent axial displacement of a workpiece, comprising:
- a first nut having a first internal thread, a frusto-conical cavity at a first axial end of said first nut, said cavity having a first surface at the bottom of said cavity, said first nut further having a generally planar second surface at a second axial end of said first nut, wherein said second surface of said first nut is positioned adjacent the workpiece to prevent axial displacement thereof;
- a second nut having a second internal thread of opposite hand as the first thread of said first nut, a frusto-conical protrusion at an axial end of said second nut, wherein said protrusion of said second nut is complimentary to and positioned adjacent said cavity of said first nut to prevent relative movement therebetween, and said protrusion does not contact said first surface at the bottom of said cavity of said first nut.
A locking nut assembly to prevent axial displacement of a wheel hub, comprising:
- a spindle having a first end, a longitudinal first surface with a twice-reduced outside diameter adjacent said first end, a first external thread on said first surface, a second longitudinal surface with a reduced outside diameter adjacent said first threaded surface, a second external thread on said second surface, said second external thread of opposite hand as said first threaded surface;
- a wheel hub mounted on said spindle;
- a first nut having a first internal thread, a frusto-conical cavity at a first axial end of said first nut, a first surface at a second axial end of said first nut, said first nut threadably engaged with said second threaded surface of said shaft and said second surface of said first nut is positioned adjacent said wheel hub to prevent axial displacement thereof;
- a second nut having an internal thread of opposite hand as the thread of said first nut, a frusto-conical protrusion at an axial end of said second nut, and said protrusion of said second nut is complimentary to and positioned adjacent said cavity of said first nut to prevent relative movement therebetween.
