Title:
CAMSHAFT MADE OF CAST IRON FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS63212708
Kind Code:
A
Abstract:
A cast iron camshaft (1) for an internal combustion engine, has at one end a toothed pulley (3) engaging a toothed belt, and an internal tensile member including a screw threaded bolt (5). The bolt engages part of the camshaft (1) adjacent the end where the toothed pulley (3) is fixed, and extends along a longitudinal bore (6), and has a screw threaded end (8) which engages an internal thread (9) positioned adjacent the point where the bending moment exerted on the camshaft by the toothed belt tension P becomes zero. As a result, the alternating bending loads which would otherwise occur in the vicinity of the cross-section X-X which is in danger, are converted into a continuous compressive load, which can be sustained by the cast iron material more effectively than an alternating bending load.
