本文叙述了橡胶防尘板和橡塑防尘板各自的结构、特点。货车滑动轴承采用橡胶防尘板后,轴箱的防尘、防水、防漏油性能提高了,减少了热轴、燃轴。若改用橡塑防尘板不仅降低密封性能,而且成本提高、检修不便。文章还简述了货车滑动轴承轮箱的定位机理,提出在货车滑动轴承轴箱内装用轴颈挡,以解决车轴与轴箱之间的定位问题。
This paper describes the structure of the rubber dust board and rubber dust board, the characteristics. Freight truck sliding bearings with rubber dust board, axle box dust, water, oil leak-proof performance increased, reducing the hot shaft, burning shaft. If the switch to rubber dustproof not only reduce the sealing performance, but also increase the cost of maintenance inconvenience. The article also briefly describes the positioning mechanism of the truck’s sliding bearing wheelbox. It proposes that the journal block be installed inside the truck’s sliding bearing axlebox to solve the positioning problem between the axlebox and the axlebox.
