Abstract Interference fit joint can transfer large torque, strong reliability, centering precision higher merit, widely used in keyless connection, and the keyless coupling field plays a more and more important role。 This paper introduces the design of a shaft hole interference fit with the hydraulic push-pull device for dismantling dismantling interference fit joint。
This article introduces the working principle and installation technology of the hydraulic push and pull device, and establishes the three-dimensional model of the hydraulic push and pull device with the 3D modeling software SolidWorks。 Then the finite element analysis is performed on the push and pull device and the rigid piston。 The nonlinear structure statics analysis is made by using ANSYS software。 The stress and deformation results of the hydraulic push pull device are analyzed to check the structure。 And draw the part two dimensional engineering drawing。
Using CFD computational fluid dynamics analysis software to use SolidWorks to establish the oil inlet and the oil circuit model to do the fluid analysis and calculation。 Using Gambit software to deal with the model, Fluent is used to simulate the flow field of the thrust and pressure oil path, and the calculation results are given in the form of image。 This has an important reference value for the practice of hydraulic push pull device。
