CA72发动机曲轴CA72发动机曲轴是八缸发动机的曲轴。材料是25号钢。从零件图上来看,CA72曲轴的特点,是连杆轴颈4个(每个连杆轴颈上装配两只连杆),主轴颈5个。连杆轴颈之间互成为90°,此90°的公差为±10’。除掉平衡块的厚度表面上不加工外,两侧面与外廓全部加工。平衡块在径向不是对称的,幅角也不相同,有100°与108°两种,不对称的幅角为40°与34°。平衡块在曲轴的
CA72 Engine Crank CA72 Engine Crankshaft is the crankshaft of an eight cylinder engine. Material is 25 steel. From the parts diagram point of view, CA72 crankshaft is characterized by four connecting rod (each connecting rod journal equipped with two connecting rod), the main journal 5. The connecting rod journals are 90 ° to each other and the 90 ° tolerance is ± 10 ’. Remove the balance of the thickness of the surface of the block is not machined, both sides of the surface and all the processing. The balance weight is not symmetrical in the radial direction, and the angles are not the same. There are two types of balancers, 100 ° and 108 °, and the asymmetrical angles are 40 ° and 34 °. Balance block on the crankshaft
