Background
In the high-end precision numerical control machine tool which is widely used at present, a precision ball screw pair with a double-nut structure is one of the main precision functional parts which are used most frequently, and the precision ball screw pair almost occupies most of the market of precision transmission functional parts with good precision characteristics and long-term use characteristics. However, the currently used double-nut structure has a fatal defect, in order to meet the axial bearing capacity of a machine tool, the double-nut screw pair is realized by increasing the pretightening force between the double nuts, and the excessive pretightening force accelerates the abrasion of the screw. Moreover, because only one section of the screw stroke is frequently used, after a new screw product is used for a period of time, the used section is seriously abraded, and the reverse clearance of the ball screw in the section of stroke which cannot ensure the uniform use of the full stroke is inevitably larger than that of the section which is not frequently used; at this time, no matter the mechanical method or the electrical method, the complete compensation can not be carried out on different reverse clearances on the same screw rod;
therefore, certain disadvantages are inevitably caused to the transmission accuracy of the ball screw assembly, and the influence cannot be eliminated at present. Once the phenomenon of excessive 'uneven wear' occurs in a certain stroke of the screw, the whole machine tool transmission part needs to be disassembled, the screw is taken out, and the whole machine tool transmission part is replaced integrally, so that high maintenance cost is brought, therefore, the utility model discloses a research and development personnel propose a pressure medium spring and a transmission nut using the pressure medium spring in earlier stage, including a pressure medium spring inner ring, a pressure medium spring outer ring, a pressure medium spring annular piston, a first pressure chamber, a second pressure chamber and an anti-rotation connecting piece, wherein the first pressure chamber is arranged at the other end of the pressure medium spring annular piston, and a pressure medium in the first pressure chamber can push the pressure medium spring annular piston to slide along the pressure medium spring inner ring and the pressure medium spring outer ring, the second pressure chamber is arranged at the outer side of the pressure medium spring annular piston, and a pressure medium in the second pressure chamber can push the pressure medium spring annular piston to slide along the pressure medium spring inner ring and the pressure medium spring outer ring, which is described in patent CN 8978 zxft, the above-mentioned problems are solved, but the research and development personnel find that the pressure medium spring can not be used for preventing the nut from rotating in the necessary connecting piece from rotating in the use process.
