偏心环是35匹拖拉机分配式油泵中的主要零件,过去經常要折断括片,使拖垃机无法启动或停止运轉,经过长时間的摸索与公兴动力机厂同志的研討和試制,解决了偏心环断括片的质量关。偏心环的作用見图1,当轉子1旋轉时,进入偏心环4内的油被括片3压到轉子心部的左面,靠凸輪圈2的作用,把油分別压出。如果偏心环內部曲綫制造精度不高,括片要漏油,使压入轉子心部的油减少或断油,則凸轮圈压出泵外的油也减少,影响起动及低速时
Eccentric ring is the main part of 35 tractor distributed oil pump. In the past, it was often necessary to break the brackets so that the tractor could not start or stop running. After a long period of exploration and discussion with the manufacturer of Gongxing Power Machinery Factory, Eccentric ring off the quality of the film off. The role of the eccentric ring shown in Figure 1, when the rotor 1 rotates, the oil into the eccentric ring 4 is pressed to the rotor core 3 by the left side of the heart, by the role of the cam ring 2, respectively, out of the oil. If the production of eccentric ring internal curve is not high precision, pieces of oil to be leaky, so that pressed into the heart of the rotor to reduce or cut off the oil, the cam ring out of the pump out of the oil also reduces the impact of starting and low speed
