ROLLER ROCKER ARM |
摘要 |
The invention provides a rocker arm having a cold formed steel body including parallel side walls and a bearing housing in the form of a sleeve attached to the side walls and defining a through opening to receive needle bearings. The sleeve has surfaces resistant to gas hardening so that after the arm has bee n subject to gas hardening only the main body is hardened leaving the sleeve unaffecte d. A method of making the rocker arm according to the invention includes preparing a sleeve having a surface which is resistant to gas hardening and which is unaffected by brazing temperatures; attaching the sleeve to the arm by brazing; and gas hardening the completed arm at a temperature less than the brazing temperature. |
