Abstract

The invention provides an acceleration test device for the service life of ball lead screws. The test device comprises a position signal detection device, a driving device (1), the ball lead screws, awork table (5), a stirring head (8), a movable groove (9), an adjustable damper (10) and an execution control unit (11); the dynamic load adjustment can be achieved, the test device can adapt to tests for different types of ball lead screws, the working condition of the ball lead screws is truly simulated, and test results are more accurate; meanwhile, by increasing an acceleration factor, the test cycle for the service life of the ball lead screws can be greatly shortened, and service life data of the entire life cycle of the products is obtained within a short time.

Description

technical field [0001] The invention relates to the field of ball screws, in particular to a ball screw accelerated life testing device. Background technique [0002] Ball screw is a component that converts rotary motion into linear motion, or converts linear motion into rotary motion. It is widely used in equipment, engineering, automobile, aerospace and other fields. It has the characteristics of high precision, reversibility and high efficiency. Small frictional resistance. Ball screw is composed of lead screw, lead screw nut, steel ball, reverser, dustproof device, etc. There are two types of steel ball circulation: internal circulation and external circulation. [0003] The main failure mode of the ball screw is fatigue damage, that is, fatigue pitting of the ball, the screw raceway, and the nut raceway. At present, the detection device used to detect the life (fatigue) of the ball screw has the defects of complex structure, long test cycle time, low adaptability, ina...
