A loading and measuring device for a full-sea depth simulated friction and wear test bench

Abstract

The invention discloses a loading and measuring device for a full sea depth simulation frictional wearing bed stand. The loading and measuring device mainly comprises a test force loading component and a measuring component, wherein the loading component can realize same-lateral and different-axis type loading through an annular loading cylinder, so that the sealing quantity can be reduced while the rigidity of a driving shaft can be guaranteed; the driving shaft is made from a compound material and has a non-contact type sealing structure; the interference of contact sealing on the transferring and measurement for the friction torque can be eliminated; the test force measuring component is used for converting the measurement for the loading force into the measurement for the displacement of a piston rod on the exterior of a high-pressure kettle; the transferring and measuring processes of the loading force are relatively independent from each other, so that the interference of frictional force and friction torque generated by the high-pressure sealing on the loading force measurement can be eliminated. On the full sea depth simulation frictional wearing bed stand, the loading and measuring device provided by the invention can realize the accurate transferring and accurate measurement for the friction torque and the frictional force between the interior and exterior of the high-pressure kettle, so that the problem of friction test under deep sea environment can be solved.

Description

technical field [0001] The invention belongs to the field of friction and wear test bench design, and in particular relates to a spring loading assembly for simulating a friction and wear test bench in an ultra-high pressure marine environment. Background technique [0002] With the depletion of various land resources, the exploration and exploitation of marine resources is of great strategic significance to improve the environment for human survival and development. In 2016, the Ministry of Science and Technology of my country launched the research work on the relevant equipment of the whole sea depth. Because marine equipment, especially deep-sea equipment is the basis for the development of marine technology, and deep-sea materials are the basis for the development of marine equipment. At present, the friction pairs of some key components and devices in deep-sea equipment work directly in harsh marine environments, such as slipper / swash plate, plunger / plunger sleeve of s...
