[0047] Such as figure 1 , figure 2 A flexible shaft test platform shown, the platform includes a frame, a drive mechanism, a torque loading mechanism, a yaw mechanism, a pressure loading mechanism, an electrical control recovery system and a data acquisition system; the frame includes a first The frame 1 and the second frame 2, the first frame 1 and the second frame 2 are arranged oppositely, the driving mechanism is arranged on the first frame 1, and the torque loading mechanism and the pressure loading mechanism are arranged on the second frame 2; the first frame 1 and the second frame 2 are respectively arranged on two H steels 13, and the first frame 1 is fixedly arranged on one side of the H steel 13, and is respectively provided with Linear slide rail 14, the bottom of the second frame 2 is provided with a slide plate 15, the slide plate 15 is arranged on the linear slide rail 14, and a screw nut 16 is provided at the bottom of the slide plate 15, between two H steels ...

Embodiment 2

[0056] The equipment shown in Example 1 is used below to realize the eccentric simulation and axial force and torque loading of the flexible shaft by using the simulation plug-in of the solidworks software in view of the actual stress on the flexible shaft. Analyze its deformation and stress through software static stress, verify the strength, and optimize the design.

[0057] 1. Static Stress Analysis Program

[0058] The whole static stress analysis process is carried out in three steps:

[0059] eccentric simulation;

[0060] Axial force loading;

[0061] Torque loading.

[0062] Record the results of the above three parts separately, and analyze the stress and deformation. Through the whole analysis process, the stress concentration parts of the flexible shaft are sorted out, and the structural design optimization scheme is proposed.

[0063] 2. Stress Analysis

[0064] 2.1 Eccentric simulation

[0065] Fix the internal thread at the left end of the flexible shaft...

Abstract

The invention relates to detection equipment for mechanical transmission parts, and especially relates to a flexible shaft test platform and a detection method. The flexible shaft test platform comprises a frame, a first driving mechanism, a second driving mechanism, a deflection mechanism, a loading mechanism, an electrical control recovery system and a data acquisition system. The test platformtruly simulates the stress motion condition of the flexible shaft, collects test data, further analyzes and optimizes the design of the flexible shaft, and improves the reliability of an electric submersible screw pump system.

Description

technical field [0001] The application relates to testing equipment for mechanical transmission components, in particular to a flexible shaft test platform and a testing method. Background technique [0002] With the in-depth development of my country's oil and gas resources, the traditional surface-driven oil production system can no longer adapt to the production of oil layers with high sand content, high gas content, low permeability, and viscous oil layers. The system puts the power source - submersible motor downhole, and combines the advantages of the screw pump, which can meet the above well conditions and production conditions, and provide technical support for the secondary development of old oilfields and low-efficiency oilfields. [0003] At present, the system in the industry consists of six parts: control cabinet, cable, screw pump, reducer, protector, and asynchronous submersible motor. The life of the reducer has not been effectively improved, resulting in the...
