Oil damping mechanism of buffer device

The invention discloses an oil damping mechanism of a buffer device. The oil damping mechanism of the buffer device comprises an oil needle and an oil hole baffle ring; the oil needle includes a variable-section structured main body with small top and large bottom, and a spherical surface structured bottom; the cross section, perpendicular to the length direction of the oil needle, of the variable section structure is a section formed by smoothing a polygon, and arc lines of all circular angle sections of one section extend to form a circle; and the oil hole baffle ring is in clearance fit with the upper part of the oil needle. The oil damping mechanism of the buffer device is stable in main oil hole flow coefficient in the use process, guarantees stability in the aircraft landing process, and improves comfort in the landing process. 本发明公开了种缓冲装置的油液阻尼机构。所述缓冲装置的油液阻尼机构包括油针和油孔挡环；所述油针包括主体为上小下大的变截面结构和底部为球面结构；所述变截面结构垂直于油针长度方向的横截面为多边形倒圆角后形成的截面，且某横截面的所有圆角段的弧线延伸后形成个圆；所述油孔挡环与所述油针的上部间隙配合。本发明在使用过程中主油孔流量系数稳定保证了飞机着陆过程中的稳定性并
