Camshaft drive system for diesel injection pump, has cam roller forming contact line together with cam path, where cam path is formed such that contact line with cam shaft axis encloses angle based on rotation of cam shaft

摘要

The system (1) has a camshaft (3) accommodated in a housing (2) and movably supported around a camshaft axis (4), where the cam shaft has a cam section between friction bearings. A cam roller (6) rolls on a cam path (5) of the cam shaft for performing a stroke movement in a stroke axis. The cam roller together with the cam path forms a contact line (8), where the cam path is formed in such a manner that the contact line with the cam shaft axis encloses an angle based on the rotation of the cam shaft.
