1、十字万向节的结构因素

1, the structural factors of the cross universal joint

从该油嘴处用黄油枪是很难将黄油加注到滚针轴承上的。众所周知，黄油的粘度大，当用黄油枪从该油嘴向万向节十字轴滚针轴承内腔加注黄油时，黄油进入狭窄内腔油道时阻力加大，黄油压力升高顶开油嘴对面的减压阀而溢出。这个现象还会被驾驶员和修理人员误认为已经加满了黄油。而实际上黄油根本就没进入滚针之间。

It is difficult to pour butter onto needle roller bearings from grease gun. As we all know, the viscosity of the butter is large. When butter is added to the inner cavity of the pin bearing of the cardan cross shaft with a butter gun, the resistance increases when the butter enters the narrow inner cavity oil channel, and the pressure rises to top the pressure relief valve opposite the nozzle and spilt. This phenomenon is also mistaken for drivers and repairmen to have been filled with butter. In fact, butter did not enter the needle at all.

2、黄油本身的理化成份因素

2, the physicochemical composition factors of butter itself

有汽车维修人员把熔化的黄油注入十字万向节或而使其到达所规定的润滑部位。但由于黄油本身的特性也使该处达不到有效润滑。这是扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训由于普通黄油的特性而导致的。其具体如下

There are vehicle maintenance personnel to melt melted butter into the cross joint or to reach the specified lubrication area. However, due to the characteristics of the butter itself, it can not achieve effective lubrication. This is due to the characteristics of ordinary butter. The details are as follows

①、万向节在工作中要承受很大的扭力和交变载荷，而钙基润滑脂的油膜坚韧程度较差，在轴承与轴颈的摩擦表面难以形成良好的油膜。

(1) a great deal of torsion and alternating load should be borne in the work, and the toughness of the calcium based grease is poor, and it is difficult to form a good oil film on the friction surface of the bearing and the journal.
