Staggered elliptic tile bearing for high-speed gear box

A staggered oval bush bearing for a high-speed gear box comprises an upper bush body, a lower bush body and an outer ring part, the outer ring part is of a circular ring structure, the upper bush bodyand the lower bush body are fixed to the inner circle face of the outer ring part, and the upper bush body and the lower bush body are the same in structure and are in central symmetry about the circle center of the outer ring part. In conclusion, the inner hole patterns of the elliptical bush bearing and the staggered bush bearing are organically combined together, so that not only is the high-speed stability good, but also the vibration resistance in the vertical direction and the horizontal direction is good; the overall structural design is reasonable, and normal high-speed operation of the high-speed gear box is guaranteed. 一种高速齿轮箱用错位椭圆瓦轴承，包括上瓦体、下瓦体和外环部，外环部为圆环结构，上瓦体和下瓦体固定在外环部的内圆面，上瓦体和下瓦体结构相同，上瓦体和下瓦体关于外环部的圆心呈中心对称；综上所述，本实用新型将椭圆瓦轴承和错位瓦轴承内孔型有机的结合在一起制造而成，不仅具备高速稳定性好，而且同时垂直和水平方向抗振性好；整体结构设计合理，保证了高速齿轮箱正常高速运转。
