挖掘机支重轮承载挖掘机自身质量及作业载荷,支重轮属性是衡量其品质优劣的重要标准,本文对支重轮属性及损坏及原因进行分析。1.支重轮的属性(1)结构支重轮结构如图1所示。支重轮主轴7两端的外盖2、内盖8固定在挖掘机履带架的下部,将外盖2、内盖8固定后,既能防止主轴7轴向窜动,又能防止其转动。轮体5两侧设有凸缘,可夹持履带链轨,防止履带脱轨,确保挖掘机沿履带行驶。外盖2、内盖8的内部分别设有1对浮封环4和浮封胶圈3,外盖2、内盖8固定后,将
Excavator roller bearing its own quality and job load excavator, roller properties is to measure the quality of its important criteria, this article on the roller properties and damage and the reasons for the analysis. 1. Roller attributes (1) Structure Roller structure shown in Figure 1. The outer cover 2 at both ends of the main axle 7 of the roller wheel is fixed on the lower part of the crawler frame of the excavator. After the outer cover 2 and the inner cover 8 are fixed, both the axial movement of the main shaft 7 and the rotation of the main shaft 7 can be prevented. Flanges are provided on both sides of the wheel body 5 to hold the track chain to prevent the track from derailing and to ensure that the excavator runs along the track. The inner cover 2 and the inner cover 8 are respectively provided with a pair of floating sealing rings 4 and a floating sealing rubber ring 3. After the outer cover 2 and the inner cover 8 are fixed,
