<p>The locking nut (10), designed to screw onto a shaft to hold a disc against a flange, has a tubular extension (12) with a flange (20) and a spring collar (30). The collar is slightly conical in shape, with its smaller end against the flange, and the nut has a pivoted cam lever (40) to force the collar against the flange so that its thrust surface (22) is pressed against the disc, locking it against the shaft flange.</p> |
