  • Actuator Selection - Flowserve

    actuators may be used on other than ball valves. This also means that they can't allow for torque curves of the equipment being actuated, without making the actuator selection process more cumbersome. The .80 torque factor does not apply to our double-acting actuators because the output torque is constant over the full stroke. Thus, double-

  • Calculation of ball bearing speed-varying ... - ScienceDirect

    The internal geometry of a ball and raceways is shown in Fig. 2. If the bearing is load-free, the centers of inner raceway groove curvature O i, outer raceway groove curvature O o and that of balls O b are collinear. Once the bearing is operating, the ball center O b will shift to the position of O b due to centrifugal force.

  • Magnus effect - Wikipedia

    The Magnus effect is an observable phenomenon that is commonly associated with a spinning object moving through the air or a fluid.The path of the spinning object is deflected in a manner that is not present when the object is not spinning. The deflection can be explained by the difference in pressure of the fluid on opposite sides of the spinning object.
