以轻型商用车用的四冲程柴油机为例,开发了奥氏体球墨铸铁(以下简称ADI )正时齿轮,与原先的钢制齿轮相比,降低了振动和噪声,而强度与钢制相同。
Taking light-duty commercial four-stroke diesel engines as an example, austenitic ductile iron (hereinafter referred to as ADI) timing gears have been developed to reduce vibration and noise compared with the original steel gears with the same strength as steel.
