Friction wear device and method for measuring load of friction wear device

Abstract

The invention provides a frictional wear device and a load measuring method of the frictional wear device. The friction wear device comprises a pressure vessel, which comprises an end cover, a cavity and a spindle; a lower sample fixing device, which comprises a fixer and a fixing component, and the fixing component can fix the lower sample on the fixer; an upper sample fixing device, which comprises a guide disc and a positioning shaft, wherein the guide disc is mounted on the main shaft, and the positioning shaft penetrates through the guide disc and is used for fixing an upper sample; the loading device, which comprises a spring, wherein the spring abuts against the guide disc and the positioning shaft, and the spring is used for applying pressure to the upper sample towards the lower sample. The load measurement method comprises the steps that a positioning shaft is installed on a guide disc, so that the positioning shaft is fixed relative to the guide disc under the condition of no external force, and the positioning shaft can axially move relative to the guide disc under the external force; then the main shaft is stretched into the cavity along the axial direction until the end cover is mounted in the cavity; and the distance X between the guiding disc and the lowest point of the positioning shaft is measured.

Description

technical field [0001] The present application relates to the field of friction and wear of materials, in particular to a friction and wear device and a load measurement method for the friction and wear device. Background technique [0002] With the development of society and science and technology, the application fields of mechanical equipment continue to expand, and mechanical equipment in some special working environments is under the influence of high or low temperature, pressure, corrosive media and atmosphere. Compared with the general environment, the friction and wear properties of materials in these environments usually show different rules, so it is necessary to conduct experimental research on the friction and wear properties of materials in these environments. [0003] Friction and wear studies under high or low temperature, pressure, corrosive media and atmosphere environments are usually carried out in corrosion-resistant pressure vessels. [0004] The applic...

Problems solved by technology

However, the internal space of pressure vessels is generally narrow and the structure is airtight, so it is difficult to accommodate and install ordinary friction and wear devices, and it is also impossible to observe and measure the relative position of the internal structure.
