【摘要】：平衡塊式推力軸承利用上、下平衡塊之間的杠桿原理補(bǔ)償軸偏斜,為明晰平衡塊補(bǔ)償軸偏斜的運動特性,在忽略瓦塊、平衡塊、套環(huán)等運動部件間相對滾動、滑動影響的假設(shè)下,推導(dǎo)了平衡塊補(bǔ)償軸偏斜的運動方程;應(yīng)用簡化前的運動模型、熱流體動力潤滑理論,對所推導(dǎo)平衡塊補(bǔ)償軸偏斜運動方程進(jìn)行了驗證;分析了軸偏斜大小及方向、瓦塊及平衡塊結(jié)構(gòu)尺寸、瓦塊數(shù)等因素對平衡塊補(bǔ)償軸偏斜運動特性的影響。結(jié)果表明:忽略運動部件間的相對滾動和滑動,不影響對平衡塊補(bǔ)償軸偏斜運動規(guī)律的分析;平衡塊轉(zhuǎn)角、瓦塊軸向位移隨瓦塊位置角呈三角函數(shù)關(guān)系分布;瓦塊較多時,補(bǔ)償性能較差;瓦塊、平衡塊支點處圓弧半徑與平衡塊補(bǔ)償軸偏斜運動特性不相關(guān)。
[Abstract]:The lever principle between the upper and lower balance blocks is used to compensate the shaft deflection. In order to clarify the motion characteristics of the balance block compensating shaft deflection, the relative rolling between the tile block, the balance block, the sleeve ring and other moving parts is ignored. Under the assumption of the influence of sliding, the motion equation of balancing block compensating shaft deflection is deduced, and the motion equation of balance block compensation shaft deflection is verified by the simplified motion model and the theory of thermal hydrodynamic lubrication. The effects of the axial deflection size and direction, the structure size of tile and balance block, and the number of tile on the deflection characteristics of compensating shaft are analyzed. The results show that the relative rolling and sliding between moving parts do not affect the analysis of the skew motion of the compensating shaft of the balance block, the axial displacement of the tile is distributed in a trigonometric function with the angle of the tile position, and when there are more tiles, the distribution of the axial displacement of the tile with the angle of the position of the tile is trigonometric. The arc radius at the fulcrum of the tile and balance block is not related to the deflection motion of the compensating shaft of the balance block.
