Abstract

1,164,174. Forging and straightening crankshafts; altering physical properties. MOTOR INDUSTRY RESEARCH ASSOCIATION. 19 April, 1968 [14 July, 1967], No. 32562/67. Headings B3E, B3H and B3V. A tool for straightening and improving the fatigue strength of a crank-shaft during manufacture or repair comprises a solid block 4 provided with two arcuate projections 5 constituting indenters for engaging the fillets 2 of a crank-shaft 1. Smooth continuous impressions are formed in the fillets. The tool co-operates with a support block 3 which may also be provided with indenter projections. Specification 1,004,962 is referred to.
