Lock nut member
View Patent ↗A threaded locking beam nut having a plurality of locking beams configured such that the inside edge surface of each locking beam has a radially inwardly angled surface thereby forming substantially a V-shaped channel between adjacent beams.
1. 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.
2. The method of claim 1 wherein the bore is formed by a drilling operation.
3. The method of claim 1 wherein the radially inwardly angled surfaces are formed by a broaching operation.
4. The method of claim 1 wherein the continuous threads are formed by a tapping operation.
5. The method of claim 1 wherein the V-shaped channels are formed to extend beyond a diameter of the bore through the nut blank.
6. The method of claim 1 wherein the radially inwardly angled surfaces on the edge portion of the inside surfaces of each locking beam are formed to have a depth which is about equal to a depth of the threads formed on the inside surface of the locking beams.
