Rullatyönnin ja rullan pultti rullatyönnintä varten

摘要

The roller shaft (10) has a roller (13) rotatably mounted on a roller pin (11) and providing a running surface for a cam of a camshaft. The roller pin is manufactured from bearing material e.g. bearing metal such as copper aluminum alloy, and non-rotatably connected with the roller shaft over a bolt or set-screw (12). A hole (15) is integrated into the shaft for supplying lubrication oil in order to lubricate the roller mounted on the roller pin, so that a lubricating oil film is formed between the roller and the roller pin.
