有些手扶拖拉机的分离轴承用不了几天就坏,有的甚至装用几个小时就卡死。其中有的是产品质量差的原因,但大部分是由于出厂前没给分离轴承加注润滑脂所致。手扶拖拉机的分离轴承裸露在外,工作环境极为恶劣。若使用前未加入润滑脂,一旦进入灰尘,轻则早期磨损,重则发生卡死或破裂。希望厂家在生产过程中,不要漏掉给分离轴承加注润滑脂这一工序。 Some of the walking tractor bearings in less than a few days on the bad, and some even stuck with a few hours stuck. Some of them are the cause of poor product quality, but most of the reason is due to the factory did not give separate bearing grease. Walking tractor separation bearing exposed, the working environment is extremely poor. If you have not used before the grease, once into the dust, ranging from early wear and tear, heavy card stuck or broken. Hope that the manufacturers in the production process, do not miss the grease to the separation of bearing this process.
