Ball screw pair experimental bench

Abstract

The invention discloses a ball screw pair experimental bench, comprising a stand. A head plate and a tail plate are fixed on the stand, a connecting tie bar is arranged between the head plate and the tail plate, the tie bar is provided with a cylindrical sliding plate, one end of the cylindrical sliding plate is connected with a sliding plate cover, a ball nut is fastened in a central hole of theother end of the cylindrical sliding plate, a ball screw is supported on the tail plate by a rolling bearing and a bearing housing, the ball nut is screwed at one end of the ball screw, a large belt wheel is fixed at the other end of the ball screw and is connected with a small belt wheel arranged on a servo motor by a synchronous tooth belt, a hydraulic cylinder is fixed at one side of the head plate, and a piston rod coaxial with the ball screw is connected with the sliding plate cover through the head plate. When the ball screw is driven by the servo motor to rotate and drives the ball nutto axially move forwards or backwards, the sliding plate and the piston rod move along with the ball nut, and the load of the ball screw can be regulated by regulating the pressure of a hydraulic oilcylinder. The experimental bench has stable performance, high operation speed, wide adjustable range of the load, high speed of system response and high precision.

Description

technical field [0001] The invention relates to a test bench for a ball screw pair. Background technique [0002] At present, high-speed and large-load ball screw pairs mainly rely on imports. Compared with advanced countries, there is still a certain gap between the development level of domestic high-speed and large-load ball screw pairs. In addition to factors such as the accuracy of raw materials and processing equipment, there is no perfect test and detection. Means are also an important reason restricting its development. Without advanced detection methods, it is difficult to understand the performance of the product, and it is impossible to provide effective and comparable data for product improvement. At present, although the domestic ball screw pair performance tests are relatively comprehensive, they are all carried out when the load condition is no load or light load. The application range of the ball screw pair tested is mainly for transmission rather than load t...

Without advanced testing methods, it is difficult to understand the performance of the product, and it is impossible to provide effective and comparable data for product improvement

At present, although the domestic ball screw pair performance tests are relatively comprehensive, they are all carried out when the load condition is no load or light load. The application range of the ball screw pair tested is mainly for transmission rather than load transmission, which cannot be accurately simulated. Working conditions of high speed and heavy load ball screw pair
