The research works provided a kind of effective method for the development and design of 3 axle rotary flexible hinge with high axial rigidity.
该研究工作为高轴向刚度三轴转动柔性铰的开发与设计提供了一种有效的方法。
The axial fixed position preload is applied to middle ring of the shaft, the axial rigidity of the angular contact ball bearing is obtained by the impulse excitation tests.
对转台中环主轴施加轴向定位预紧力，通过脉冲激励法试验得到角接触球轴承的轴向刚度，试验结果与理论结果吻合较好，为转台研制中各轴系预紧量的控制提供了理论和实验依据。
Cylindrical roller adopt convexity process, so the presses of roller and race surface are proportional spacing, they can bear a large axial load, furthermore axial rigidity is strong.
圆柱滚子采用凸面加工，因此滚子与滚道之间的压力分布均匀。可承受较大单向轴向负荷，且轴向的刚性较强。
