Patent number: 5795037Abstract: A novel axle nut system is provided on the spindle ends of an axle which mounts a wheel assembly that includes tapered roller bearings. The axle nut system of the present invention includes an adjustment nut, a washer and a retainer member. The adjustment nut is threaded into position having torque applied to it in a controlled manner to achieve specific preload bearing pressure against the outer bearings. Thereafter, the washer is placed into contact with the nut and is rotationally fixed with respect to the axle. Next, the threaded retainer member is rotated into contact with the washer. With the threaded retainer member placed on the axle to prevent any outward movement of either the wheel assembly components or the adjustment nut and washer, the adjustment nut is rotated in the opposite direction by which it was installed until it jams forcibly against the washer and thus, the threaded retainer member.Type: GrantFiled: May 23, 1996Date of Patent: August 18, 1998Assignee: Hub Nut CorporationInventor: George Allan Hagelthorn
