目前国内及国外的轿车上或轻型车上,发动机通常使用正时齿轮皮带传动,取代齿轮传动和链条的传动,提高了传动精确度,减轻了发动机噪声。 实践中我们对正时齿轮皮带的使用情况看,还存在一些问题。例如:皮带压紧轮松动,曲轴带不动凸轮轴(打扫滑)使发动机无法运转。曲轴油封漏油,润滑油滴落在正时皮带上,损坏了正时皮带。 为了使发动机和正时齿轮及皮带能正常工作。不受外界不正常因素影 At present, domestic and foreign cars or light vehicles, the engine usually uses timing gear belt drive, instead of gear and chain drive, improve the transmission accuracy and reduce engine noise. In practice we use timing belt gear, there are still some problems. For example: the belt pressure wheel loose, the crankshaft with a fixed camshaft (cleaning slip) so that the engine can not run. Crankshaft seal leakage, oil dripping on the timing belt, damaged timing belt. In order for the engine and timing gears and belts to work properly. Unaffected by external factors
