Machine Design
The property of a bearing material which has the ability to accommodate shaft deflections and bearing inaccuracies by plastic deformation without excessive wear and heating, is known as
One smaller nut is tightened over main nut and main nut tightened against smaller one by loosening, creating friction jamming
A hard fibre or nylon cotter is recessed in the nut and becomes threaded as the nut is screwed on the bolt causing a tight grip
Through slots are made at top and a cotter pin is passed through these and a hole in the bolt, and cotter pin splitted and bent in reverse direction at the other end
A slot is cut partly in middle of nut and then slot reduced by tightening screw
