Abstract
A threaded locking beam nut (20) having a plurality of locking beams (22) configured such that the inside edge surface (27, 28) of each locking beam has a radially inwardly angled surface (32, 34) thereby forming substantially a V-shaped channel between adjacent beams.
Claims
1. A lock nut adapted to receive an externally threaded member comprising: a substantially rigid body having a circular opening extending through the body, and a plurality of resilient, circumferentially-spaced locking beams integral with the rigid body and projecting outwardly from one end thereof, each of the locking beams has an inner surface that defines an opening aligned with the circular opening in the body, the locking beams tapering radially inwardly such that the opening defined thereby has a uniformly-decreasing diameter, wherein the aligned openings defined by the respective rigid body and plurality of locking beams contain threads for receiving the externally threaded member, the locking beams resiliently deflecting radially outwardly to lock the member in place, wherein the plurality of locking beams each have sidewalls arranged in spaced relationship with the sidewalls of circumferentially-adjacent locking beams, each sidewall being continuous, from the beam's inner, threaded surface to the beam's outer surface, wherein the inner surface of each locking beam has an angled surface along each edge extending radially inwardly to form a substantially V-shaped slot between each beam, and wherein the angled surface on the inner surface of the locking beams has a maximum diameter extending between opposite V-shaped slots which is about equal to or slightly greater than a major diameter of the threads.
2. The lock nut of claim 1 wherein the sidewalls of adjacent locking beams form a V-shaped channel between adjacent locking beams.
3. The lock nut of claim 2 wherein the V-shaped channel has an apex located in the opening defined by the inner surface of the locking beams,
9 wherein the apex defines a diameter extending between opposite V-shaped channels which is less than a diameter of the inner surface of the locking beams.
4. The lock nut of claim 1 wherein the plurality of locking beams include six equal-sized uniformly-spaced locking beams.
5. The lock nut of claim 1 wherein the plurality of locking beams are configured such that, when the lock nut receives the externally threaded member, the locking beams deflect substantially only radially outwardly to lock the member in place.
6. A locking beam nut adapted to receive an externally threaded member comprising: a substantially rigid body having a circular opening extending therethrough; and a plurality of resilient, circumferentially-spaced substantially rectangular locking beams projecting from one end of the rigid body and having inner surfaces that cooperate to define an opening aligned with the circular opening in the body, the locking beams tapering radially inwardly such that the opening they define has a uniformly-decreasing diameter, and wherein the aligned openings defined by the respective rigid body and plurality of locking beams are threaded for receiving the externally threaded member, the locking beams resiliently deflecting radially outwardly to lock the member in place, wherein the inner surface of each locking beam has an angled edge portion extending radially inwardly to form a substantially V-shaped slot between each beam, and wherein the angled edge portion on the inner surface of the locking beams has a maximum diameter extending between opposite V-shaped slots which is about equal to or slightly greater than a major diameter of the threads.
10
7. The locking beam nut of claim 6 wherein the plurality of locking beams have a flat outer surface.
8. The locking beam nut of claim 6 wherein each locking beam has sidewalls, the sidewalls of adjacent locking beams form a V-shaped channel between adjacent locking beams.
9. The locking beam nut of claim 8 wherein the V-shaped channel has an apex located in the opening defined by the inner surface of the locking beams, wherein the apex defines a diameter extending between opposite V-shaped channels which is less than a diameter of the inner surface of the locking beams.
10 The locking beam nut of claim 6 wherein the aligned openings defined by the respective rigid body and plurality of locking beams together contain continuous threads that are uninterrupted along their entire axial length.
11. The locking beam nut of claim 6 wherein the plurality of locking beams are configured such that, when the locking beam nut receives the externally threaded member, the locking beams deflect substantially only radially outwardly to lock the member in place.
/
12. A method of manufacturing a lock nut comprising: heading a nut blank to form a plurality of V-shaped channels around an outer surface of the nut blank; forming a bore through the nut blank to form a plurality of locking beams separated by the V-shaped channels; forming radially inwardly angled surfaces on an edge portion of an inside surface of each locking beam; and forming a continuous thread on the inside surface of the locking beams.
11
13. The method of claim 12 wherein the bore is formed by a drilling operation.
14. The method of claim 12 wherein the radially inwardly angled surfaces are formed by a broaching operation. '
15. The method of claim 12 wherein the continuous threads are formed by a tapping operation.
16. The method of claim 12 wherein the V-shaped channels are formed to extend beyond a diameter of the bore through the nut blank.
17. The method of claim 12 wherein the radially inwardly angled surfaces on the edge portion of the inside surfaces of each locking beam are formed to have a maximum diameter extending between opposite radially inwardly angled surfaces about equal to or slightly greater than a major diameter of the threads.
