目前使用的砂浆搅拌机,其主要缺陷是轴端漏浆,因此,砂浆进入轴端轴承,主轴和轴承磨损严重,甚至因轴承磨损严重,主轴下降,造成主轴与减速器输出轴不同心,损坏减速器,这种灰浆搅拌机,基本每年要大修一次,每次大修更换零件多,大修费用都超过原值的1/2,甚至达到2/3,使维修费用增高很不合算。针对上述情况,我公司在以下两个方面进行了改进: 1.变速箱采用PM350变速箱,由蜗轮蜗杆传动改为正齿轮传动,所有铜套改为滚动轴承,取消机油润滑,改为黄油润滑。
The main drawback of the mortar mixer currently used is the shaft end leakage slurry. Therefore, the mortar enters the shaft end bearing, the spindle and the bearing are worn badly, and even the bearing wears seriously, the main shaft drops, causing the spindle and the output shaft of the decelerator to be different, damaged and decelerated. This type of mortar mixer is basically overhauled once a year. Every time overhauling replacement parts, overhaul costs are more than 1/2 of the original value, and even 2/3, which makes maintenance cost increase uneconomical. In view of the above situation, our company has made improvements in the following two aspects: 1. The gearbox adopts PM350 gearbox, which is changed to spur gear drive by worm gear drive. All the copper bushings are replaced by rolling bearings, and the oil lubrication is removed and replaced by grease lubrication.
