【摘要】：为了解决配重块在高速旋转中产生的离心力造成平衡盘形变,严重时破坏平衡盘的稳定自锁状态、使配重块位置滑动或平衡盘卡死无法转动的问题,利用ANSYS建立了带深沟球轴承的平衡盘三维模型。在保证平衡盘平衡能力不变的前提下,分析了不同配重块形状、不同转速、不同轴承材料以及两配重块不同平衡能力对平衡盘变形的影响。仿真结果表明:通过优化设计配重块形状、改用陶瓷轴承支撑以及两配重块设计成相同平衡能力的方法,能够有效降低平衡盘的径向以及轴向变形,提高平衡盘的允许工作转速及稳定性能。
[Abstract]:In order to solve the problem that the centrifugal force produced by the weight distribution block in the high speed rotation causes the balance disk to deform, and seriously destroys the stable self-locking state of the balance disk, it makes the weight distribution block position slide or the balance disk become stuck and cannot rotate.A three-dimensional model of balancing disc with deep groove ball bearing is established by ANSYS.On the premise of keeping the balance ability of the balancing disc unchanged, the influence of different weight distribution block shape, different rotating speed, different bearing material and different balance ability of two weight distribution blocks on the balance disc deformation is analyzed.The simulation results show that the radial and axial deformation of the balancing disk can be effectively reduced by optimizing the shape of the weight distribution block, using ceramic bearing support and two weight distribution blocks to design the same balance ability.Improve the allowable working speed and stability of the balancing disk.
