The rolling bearing is located in the bearing seat. The inner ring of the rolling bearing is fastened to the shaft, and the outer ring is fastened to the bearing seat. There are two radial through holes on the same plane and perpendicular to each other on the bearing seat. The two radial through holes are located in the rolling bearing The end of the bearing is connected with the inner cavity of the rolling bearing. A first sleeve is installed on one side of the bearing seat. The inner ring of the first sleeve is fastened to the shaft, and the outer ring rotates relative to the bearing seat. The first sleeve and There is a first sealing ring between the bearing seats, the first sealing ring is pressed axially by the first pressure ring, and there is a gap between the first sleeve and the end face of the rolling bearing; the second sleeve is installed on the other side of the bearing seat, The inner ring of the second sleeve is fastened to the shaft, and the outer ring and the bearing cover rotate relatively. A second sealing ring is arranged between the second sleeve and the bearing cover, and the second sealing ring is axially compressed by the second pressure ring. There is a gap between the bearing cover and the end face of the rolling bearing.
本实用新型的悬臂轴支撑装置,润滑油通过轴承座上的两个通孔进入滚动轴承,这样即使工作状态下也可以进行润滑,同时滚动轴承两端的间隙,可以保证滚珠轴承外沿的完全润滑。使用至少四个滚动轴承不仅可以使承载能力大大增强,同时使轴承座在承受瞬时冲击载荷实现一定程度的缓冲,大大增强了滚动轴承的承载能力。In the cantilever shaft support device of the utility model, the lubricating oil enters the rolling bearing through two through holes on the bearing seat, so that it can be lubricated even in the working state, and at the same time, the gap between the two ends of the rolling bearing can ensure the complete lubrication of the outer edge of the ball bearing. The use of at least four rolling bearings can not only greatly enhance the bearing capacity, but also enable the bearing housing to achieve a certain degree of buffering when subjected to instantaneous impact loads, greatly enhancing the bearing capacity of the rolling bearings.
本实用新型结构简单,润滑方便快捷,可实现连续润滑;轴向承载能力大大增强,轴承的疲劳寿命也会大大增加;单侧支撑时,能承受较大的径向力,稳定性好。The utility model has the advantages of simple structure, convenient and fast lubrication, and can realize continuous lubrication; the axial bearing capacity is greatly enhanced, and the fatigue life of the bearing will also be greatly increased; when supported on one side, it can bear large radial force and has good stability.
