In order to improve the working accuracy of the feed system, the ball screw mechanism must have a high transmission stiffness. In addition to increasing the stiffness of the ball screw itself, the ball screw mechanism must be designed with a sufficiently rigid support structure and must be installed correctly. The factors that affect the rigidity of the support structure include the stiffness of the bearing seat, the contact area between the bearing seat and the machine structure, and the stiffness of the bearing.
Universal ball screw, using angular contact ball bearings is sufficient. Install the bearings "face to face" on the two supporting shaft ends of the ball screw. If it is a specialized screw rod for special equipment, and if the equipment installation manual requires the use of specialized bearings, then assemble according to the relevant instructions.
In the load bearing capacity of the ball screw, both radial and axial loads exist simultaneously, and consideration should be given to the selection of bearings. Commonly used bearings that can withstand the load simultaneously include angular contact bearings and tapered roller bearings. The former focuses on dry light load and high-speed fields, while the latter focuses on heavy load and low-speed situations. It should be noted that the above two types of bearings are generally used in pairs and installed relative to each other (face to face or back to back), which can limit the axial movement of the screw rod.
Ball screw has a number of features that set it apart from other screws, including high efficiency, low temperature rise, high precision, high speed, high rigidity, high reversibility, low maintenance, and a long service life. Its high efficiency is ensured by testing equipment and quality control processes, with results of over ninety percent. Low temperature rise is made possible by the superior surface quality of the screw track and the strict ball sizing.
Furthermore, the screw drive pair can achieve a high positioning accuracy due to the small temperature increase and pre-tightening and clearance elimination measures. Its excellent design and careful manufacturing give it a reliable high speed performance, reaching up to 60M/min and more.
Moreover, with the screw rod and nut both being made with excellent material and pre-tightening and clearance elimination, the ball screw will have a high rigidity. As there is no viscous friction between the screw and nut, the transmission will not be affected by the creeping phenomenon. The dust prevention device also eliminates the need for frequent maintenance.
In addition, the screw and nut are made with high carbon steel and alloy steel, respectively, which both have a surface hardness HRC62, thus improving its lifespan.
