Ball bearing common way of ball screw according to the situation by force at work, often thrust screw support bearings and radial ball bearing assembly, ball Which is good, which is supported in the following ways: 1, a single push of a single push of the thrust bearings are mounted on both ends of the ball screw and preloaded. It can improve the axial stiffness of the ball screw; when pre-stretched install preload large, so bear only pulling work when the screw. 2, a pair of push-push-push attached to both ends of the thrust bearing and the combination of radial ball bearings, buy a ball screw, as the screw has a maximum stiffness, which can be used at both ends of double bearing, ball use, first-served basis thrust bearing and radial ball bearings, and clamping force is applied to the top. This method is suitable for high rigidity, Anhui ball screw, high-speed high-precision precision lead screw drive system. However, this structure allows the thermal deformation mode conversion screw preload the thrust bearing, thus requiring stents increase the carrying capacity and stiffness of the thrust bearing design. Hollow ball screw use of time for that? What are the advantages? A. Are generally more suitable for full-on ball screw machine temperature requirements more stringent. Hollow ball screw, since it is possible through the oil or water to cool the screw, it is difficult to heat the screw itself, can effectively control the temperature, to achieve the purpose of accuracy and stability. B. hollow ball screw has the advantage of reduced weight, and therefore relatively easy to screw sagging under its own weight is too large, and due to the reduction of inertia of the screw, the motor driving torque reduced; the other hand, since the hollow portion of the screw can be the coolant flows through and achieve lower screw temperature only and therefore the temperature of the ball screw deputy can be better controlled.
