【摘要】：通过分析外摆线型单螺杆泵螺杆-衬套副的相对运动,发现螺杆-衬套副的固定接触点出现在衬套骨线上,衬套可采用金属材料,螺杆可在金属基体表面黏接橡胶外套;用瞬心法推导出齿凸接触点和齿凹接触点处相对滑动速度的计算公式,并用MATLAB生成速度曲线,用SolidWorks建立螺杆泵实体模型,用SolidWorks Motion进行运动仿真,对比速度仿真值与速度公式曲线可知,拟合度很高,最大偏差率仅为-0.101%;将速度曲线与啮合状态进行对应,发现齿凹接触点处相对滑动速度的最大值发生在螺杆齿凸中点与衬套齿凹中点相接触处,齿凸接触点处相对滑动速度最大值发生在螺杆齿凸中点与衬套齿凸中点相接触处。
[Abstract]:By analyzing the relative motion of the screw bushing pair of the cycloidal single screw pump, it is found that the fixed contact point of the screw bushing pair appears on the bushing bone line, the bushing can be made of metal material, and the screw can be bonded to the rubber jacket on the surface of the metal substrate. The formula of relative sliding velocity between tooth convex contact point and tooth concave contact point is derived by instantaneous center method. The velocity curve is generated by MATLAB, the solid model of screw pump is established by SolidWorks, and the motion simulation is carried out by SolidWorks Motion. Comparing the velocity simulation value with the velocity formula curve, we can see that the fitting degree is very high, the maximum deviation rate is only -0.101, and the velocity curve is corresponding to the meshing state. It is found that the maximum relative slip velocity at the contact point of tooth concave occurs at the contact point between the middle point of the screw tooth convex and the middle point of the bushing tooth concave, and the maximum value of the relative slip velocity at the contact point of the tooth convex point occurs at the contact point between the middle point of the screw tooth convex and the middle point of the bushing tooth convex.
