Building a model of the process of grinding screws for ball-screw transmission

Abstract

Abstract Studies of domestic and foreign scientists show that the radius of the thread profile has a significant impact on the performance of BS transmissions: load capacity, rigidity, smoothness and durability. Therefore, the accuracy of the thread profile is high requirements. In order to ensure the high quality of transmission functioning, it is very important to obtain a minimum deviation on the entire length of the propeller of parameters such as the moment of idling, the changes of which characterize the smoothness of the work, and the rigidity on which it depends. precision of movement and installation in the required position of the machine’s working organs. Therefore, special attention is paid to ensuring the stability of the thread profile radius. For ensuring the stability of the radius of the thread profile, the article developed a mathematical model of the thread grinding process that ensures the preservation of the circle profile. It is shown that the obtained mathematical model requires experimental verification in the conditions of grinding the thread of the rolling screws and, if necessary, its corresponding refinement.
