Rocker arm assembly and components therefor

摘要

A method of precision manufacture of an outer arm of a rocker arm assembly is performed by determining structures of a rough outer arm that would require precision processing and locations to support the structures as they are processed. Starting with at least one structure requiring precision processing, locations on the outer arm close to the structure to hold the outer arm during processing are determined that would cause minimal distortion of the outer arm during processing. The outer arm is then provided with clamping lobes at these locations. The clamping lobes of the outer arm are clamping into a fixture for manufacturing. The slider pad may now be precision ground while the outer arm is clamped in the fixture with minimal risk of distortion of the outer arm.

1. A method of precision manufacture of an outer arm of a rocker arm assembly comprising the steps of:
identifying at least one structure of the outer arm requiring precision processing; determining locations on the outer arm close to the at least one structure requiring the precision processing to hold the outer arm during the precision processing to cause minimal distortion of the outer arm during the precision processing; providing an outer arm with clamping lobes at the determined locations; clamping the outer arm at the clamping lobes in a fixture; and precision processing the at least one structure while the outer arm is clamped in the fixture.
