在1957年4月份改用銅軸瓦(見附图),使用到現在,效果很好,预計其使用寿命为一年至一年半。如以彈子軸承的使用寿命为1个月計算,則改裝轴瓦后,每台每年能节約10568元,并且还易于檢修。为了延長軸瓦的使用寿命,除定期清洗和更换填料外,笔者还認为应当尽量加大軸瓦尺寸,采用硬度大的巴比合金。軸瓦潤滑用油杯定期加入鈣基潤滑脂。 1.5 儲油腔;1.端盖;3.巴比合金;
In April 1957 the use of copper bush (see photo), use up to now, the effect is very good, it is estimated that the service life of one year to a year and a half. If the service life of the ball bearing is calculated as one month, then the conversion of bushings, each can save 10568 yuan per year, and is also easy to overhaul. In order to extend the service life of bearings, in addition to regular cleaning and replacement of filler, I also believe that should maximize the size of the bush, the hardness of the Barbie alloy. Lubricate the bearing pad regularly with calcium-based grease. 1.5 oil storage chamber; 1. End cap; 3. Barbie alloy;
