Problems solved by technology

[0003] In the existing technology, the fixtures of the testing machine are often single-position clamping, which brings inconvenience to the repetitive test under the same test conditions, and also has defects in the utilization rate of the sample material and test efficiency.
In 2011, Jiao Jian (Jiao Jian. Design and research on ring-block friction and wear testing machine [J]. World Manufacturing Technology and Equipment Market, 2011, (04)) designed the ring-block friction and wear testing machine, and the sample clamping device adopted A special fixture with a simple structure, with

Abstract

The invention discloses a desk type annular block abrasion and wear tester. The tester comprises a driving part, a testing part, a measuring part, and a loading part; the motor of the driving part is fixed on a motor support, a test ring is directly driven to rotate by the motor shaft; the test ring in the testing part is arranged on a sleeve which is connected to the motor shaft, a test block is tightly clamped with wedges in a bottom seat clamp which can be arranged in a plurality of positions; the measuring part is composed of a temperature sensor and a force measuring sensor; the loading part is manually operated, a bevel wheel drives a screw rod to push a spring support plate, and then the spring pushes a workbench move upward so as to tightly press the test ring to the test block. The desk type annular block abrasion and wear tester can effectively measure the test piece temperature, frictional force, and change of frictional coefficient under different loads.

Description

technical field [0001] The invention relates to a mechanical friction and wear test device, in particular to a table-top ring block friction and wear tester. Background technique [0002] When the machine is running, the friction between the various moving mechanisms causes useless loss of energy and shortens the life of the machine, and reduces the working efficiency of the mechanical equipment. Therefore, it is very important to effectively evaluate the friction characteristics of the moving mechanism. The coefficient of friction is an important parameter to characterize the tribological properties of materials such as friction reduction performance and wear resistance effect. Therefore, it is necessary to measure the friction coefficient of the test material when studying the mutual friction motion of static and dynamic samples. [0003] In the prior art, the fixtures of the testing machine are often single-position clamping, which brings inconvenience to repeated tests u...
