Abstract

본 발명은 기계부품의 소재 특성 시험장치에 관한 것으로 특히 한번의 시험으로 여러 가지 하중에 대한 소재의 마찰 마모특성을 측정할 수 있는 한계하중 측정용 마찰 마모시험장치에 관한 것으로, 종래에는 요구하는 여러 가지 시험조건에 대한 결과의 량 만큼 시험횟수를 늘려서 여러번의 시험을 수행하여야 하며 이와 같은 방식에 의한 마모시험의 경우 매 시험시 마다 시험결과에 영향을 미치는 요인이 많아서 시험편의 교체에 따른 시험결과의 동질성을 장담하기가 어려운 문제점이 있었다.The present invention relates to a material characteristic test apparatus for mechanical parts, and more particularly, to a friction wear test apparatus for limit load measurement that can measure the friction wear characteristics of a material under various loads in a single test. The number of tests should be increased by the number of results for each test condition. In the case of the abrasion test by this method, there are many factors that affect the test results at each test. It was difficult to guarantee homogeneity.

본 발명에서는 양측의 축이 고정되어 회전하는 고정시편부와 일측은 힌지부에 의해 고정되고 타측은 중추에 의해 하중압력을 주어 동일시험편에 대하여 동시에 각 부분별로 서로 다른 압력을 가할 수 있도록 이루어진 이동시편부로 구성되어 한번의 시험 측정을 통하여 여러 가지 하중에서의 마찰 마모 특성을 동시에 측정 평가 할 수 있도록 함을 특징으로 한다.In the present invention, a moving specimen made of a fixed specimen portion which is fixed to both shafts and rotates and one side is fixed by a hinge portion and the other side is subjected to a load pressure by the center, so that different pressures can be applied to each part at the same time for the same test specimen. It is characterized by the fact that it is possible to simultaneously measure and evaluate the frictional wear characteristics at various loads through one test measurement.
