Abstract

The invention discloses a device capable of eliminating a gap between a screw and a nut. The device capable of eliminating the gap between the screw and the nut comprises the nut arranged on the screw. Two narrow grooves are radially formed in the nut and symmetrical to each other about an axis of the nut. Hex socket adjusting screws are arranged on the narrow grooves. The device capable of eliminating the gap between the screw and the nut can meet the requirement for adjusting a gap of a screw and nut pair and is even in nut deformation, high in adjusting precision, balanced in abrasion, capable of prolonging service life, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of screw nuts, in particular to a device capable of eliminating gaps between screw nuts. Background technique [0002] The feed transmission of CNC machine tools is the direct object of digital control. Regardless of point control or contour control, the final coordinate accuracy and contour accuracy of the workpiece are affected by the transmission accuracy, sensitivity and stability of the feed transmission. Therefore, the feed servo system of CNC machine tools is required to meet the requirements of small frictional resistance, high transmission accuracy and rigidity, small inertia of moving parts, and no gap. In order to ensure that there is no backlash in the transmission system, the precision of various mechanical parts must first be improved, and then various backlashes should be eliminated as much as possible, such as couplings, gear pairs, ball screw pairs and their supporting components, etc. should adopt a ...
