轴向跑偏
1.
Based on the analysis of the belt misalignment of the metal V-belt type CVT,the mechanism of the belt axial-misalignment was discussed and several methods which can eliminate the axial-misalignment was introduced.
通过对金属带式无级变速器传动钢带的轴向跑偏的分析,阐述了产生钢带中心线轴向跑偏的机理,介绍了消除传动钢带轴向跑偏的几种方法,并指出了采用曲母线带轮或改变无跑偏时的速比等控制方法的不足,为此,提出了一种电液控制方法,为消除传动钢带的轴向跑偏,取得了良好的效果。
补充资料：单轴各向异性
单轴各向异性是磁晶各向异性的最简单形式，即自发磁化的稳定方向（或易磁化方向）平行于一特殊晶轴。如六方晶系钴的自发磁化方向平行于 C轴(见晶体结构)，这就表现出强的单轴各向异性。磁性材料的单轴各向异性值一般都低于其磁晶各向异性值，为103erg/cm3量级。磁性材料经磁场热处理或强的冷加工而产生的感生各向异性，都属于单轴各向异性。
