The bearing oil of the crusher must be replaced regularly
Quality is life, high efficiency is the guarantee. Creating the Dewo brand and serving customers wholeheartedly” is the entrepreneurial tenet of our Henan Dewo crusher Machinery, and also the belief of each of our Red Stars. As a comprehensive manufacturer integrating production, sales and after-sales, We are well aware of the quality requirements of our customers for the crusher, so how can we make our crusher work efficiently even after being exposed to wind and sun? The answer is that the mandrel, eccentric shaft, and bearings should be replaced regularly. The mandrel, eccentric shaft and bearings of the crusher should be replaced with new ones.
The crusher works under impact load. The babbitt lining on the bearing has a working period of about 2 years. If the period is exceeded, it needs to be recast. If the eccentric shaft and the bearing bush, the mandrel and the bearing bush are worn, and the top clearance is greater than 1.5 times the original assembly clearance, it needs to be adjusted or replaced; if the oil groove wears 1.5mm, the oil groove should be reopened or adjusted. When the gap between the upper cover of the connecting rod head and the eccentric shaft is worn to more than 1.5 times the assembly gap, it is also necessary to add a pad for adjustment or replace with a new one. When the babbitt alloy on the crusher bearing bush is deeply peeled or scratched, it should be recast. The quality of the processed bearing has the following requirements: the color of the babbitt alloy surface should be uniform, matt, and silvery white; the babbitt alloy surface layer should not have ash, cracks, sand holes, shrinkage holes, and shell withdrawal.
