T/CAMS /CICEIA65-2021 Reciprocating Internal Combustion Engines Timing Gears Product Quality Grading and Classification Standards
T/CAMS /CICEIA65-2021
Basic Information
Scope
Scope: This standard specifies the terms and definitions, quality indicators, inspection methods, and inspection rules for three grades of timing gears for reciprocating internal combustion engines, namely Grade 1, Grade 2, and Grade 3. This standard applies to crankshaft gears, camshaft gears, fuel pump gears, oil pump drive gears, and idler gears (collectively referred to as timing gears) of reciprocating internal combustion engines with a rated power not exceeding 560 kW. Gears for air compressors and power steering pumps may also be used as reference for implementation. Main technical content: Terms and definitions, quality indicators, inspection methods, and inspection rules for three grades of timing gears for internal combustion engines, namely Grade 1, Grade 2, and Grade 3.
