宣工SD7型高驱动履带式推土机终传动装置后排行星轮轴端部,由后排行星轮轴1、后排行星架2、o形圈3、固定板4、螺栓5等组成,如图1所示。后排行星轮轴端部采用其颈部设置的O形圈进行密封,其作用主要是防止终传动中的润滑油泄漏。固定板的作用是防止后排行星轮轴发生轴向窜动。在该型推土机使用过程中,维修人员发现终传动装置后排行星轮轴端部O形圈很难更换,为此决定对其密封方式进行改进。
Propaganda SD7-type high-powered crawler dozer rear planetary gear shaft rear end, the rear planetary gear shaft 1, rear planetary carrier 2, o-ring 3, the fixed plate 4, bolts 5 and other components, as shown in Figure 1 Show. Rear planetary gear shaft ends with its neck set O-ring seal, its role is to prevent the final drive in the oil leakage. Fixed plate’s role is to prevent the rear planetary gear shaft axial play. During the operation of this type of bulldozer, maintenance personnel found it difficult to replace the O-ring of the rear planetary gear shaft at the rear of the final drive, and decided to improve the sealing method.
