Abstract

The invention discloses a device capable of adjusting and measuring pretightening force loss of a ball screw pair and an experiment table of the device. The device is formed by assembling a screw, a first screw nut, a second screw nut, a flange-type sleeve, a flange-type connecting disc, a connecting disc, an adjusting nut, a combined disc spring and three force sensors. The device is simple in structure. The method for adjusting the pretightening force loss of the ball screw pair is realized by compressing the combined disc spring through the adjusting nut, the method for measuring the pretightening force loss of the ball screw pair is realized by measuring through the force sensors, so that measuring result is guaranteed. The experiment table is simple in structure and convenient for detecting practicability of the device.

Description

technical field [0001] The invention belongs to the measurement field, and more specifically relates to a ball screw pair pretightening force loss adjustable and measuring device and a test bench thereof. Background technique [0002] Ball screw is an important component in the linear transmission system of CNC machine tools. It has the characteristics of low energy consumption, high precision and high load, and has become one of the most widely used rolling functional components for positioning and transmission. In actual use, due to design, manufacturing and assembly errors, there will always be a gap between the ball and the raceway in the ball screw pair. In order to solve the above problems, the method of applying preload is usually used to eliminate such gaps. Only by determining a reasonable preload can the working stability and positioning accuracy of the ball screw pair be effectively improved, because excessive preload Forces reduce efficiency, increase wear and c...
