我厂主要生产氨压稿机,目前生产的有2AL8、4AJ8、2AL15、4AJ15等型号,曲轴是压缩机上的主要另件,这四种型号压缩机的曲轴的尺寸分别为:2AL8:轴颈φ45毫米,全长503毫米,双拐,压缩机转速960转/分。4AJ8:轴颈φ45毫米,全长543毫米,双拐,压缩机转速960转/分。2AL15:轴颈φ90毫米,全长945毫米,双拐,压缩机转速720转/分。4AJ15:轴颈φ90毫米,全长1020毫米,双拐,压缩机转速720转/分。曲轴的主要技术要求是曲轴毛坯用45号优质碳素钢锻造,经粗加工后进行正火或调质处理,轴颈表面
Our main production of ammonia pressure machine, the current production of 2AL8, 4AJ8, 2AL15, 4AJ15 and other models, the crankshaft is the compressor on the other major pieces of these four models of the compressor crankshaft size are: 2AL8: journal φ45 Mm, length 503 mm, double shove, compressor speed 960 r / min. 4AJ8: journal φ45 mm, full length 543 mm, crutches, compressor speed 960 rev / min. 2AL15: journal φ90 mm, length 945 mm, crutches, compressor speed of 720 rev / min. 4AJ15: journal φ90 mm, full-length 1020 mm, crutches, compressor speed of 720 rev / min. The main technical requirements of the crankshaft crankshaft rough with 45 high-quality carbon steel forging, roughing after normalizing or quenching, journal surface
