一、曲轴断裂概况及影响曲轴是织机主轴,担负着织机的打纬、提花二个主要运动,是重要的传动另件。因此,设计时采用了较大的安全系数,并选用45号优质钢材制造,来保证曲轴的足够寿命。据粗略统计曲轴使用寿命在十年以上,所以曲轴应该是件不易损坏断裂的零件。可是在丝织行业的提花织机中,曲轴却断裂频繁。如杭州福华丝织厂花机车间,每年有15～20%的曲轴断裂,有些曲轴甚至只用了几个月就断了,造成了停工停产,使生产受
First, the crankshaft fracture profile and impact Crankshaft is the main shaft loom, beating the loom beating machine, jacquard two major sports, is important to drive another. Therefore, the design uses a larger safety factor, and use 45 made of high-quality steel to ensure adequate life of the crankshaft. According to the rough statistics of crankshaft service life of more than a decade, so the crankshaft should be easy to damage the broken parts. However, in the silk weaving industry jacquard loom, the crankshaft is broken frequently. Such as Hangzhou Fuhua silk factory flower shop, every year 15 to 20% of the crankshaft rupture, and some crankshaft even only a few months to break, resulting in downtime, so that the production by
