Reciprocating type piston ring-cylinder sleeve friction wear testing machine

Abstract

The invention provides a friction and abrasion tester for reciprocating piston ring-cylinder liner. The invention relates to the technical field of mechanism friction and abrasion, in particular to afriction and abrasion tester for reciprocating piston ring-cylinder liner as a friction paring element practically applied in an internal-combustion engine. A motor driven crankshaft connecting rod mechanism of the tester moves in linear reciprocation through a slide block and a guide sleeve of a guide mechanism, a loading system adopts extrusion-high strength bolting structure to change the pressure from a piston ring of the high strength bolting to the cylinder liner, a lubricator and an oil collector of a lubricating device are positioned on the loading mechanism corresponding to the position of the cylinder liner, sensors of a friction tester and a temperature measurement and a control device are connected to a data collecting card of a data collecting and monitoring device and a computer through interfaces. The invention adopts the practically applied piston ring-cylinder liner of an internal-combustion engine as a friction paring element, load, speed, temperature, lubricant supply experimental parameters can be changed; the invention can monitor temperature, friction experimental data and process experimental data.

Description

technical field [0001] The invention relates to the field of mechanical friction and wear and control, in particular to a reciprocating piston ring-cylinder liner friction and wear testing machine which uses a piston ring-cylinder liner actually used in an internal combustion engine as a friction pair. Background technique [0002] Piston ring-cylinder liner is the most important and critical motion pair in an internal combustion engine, and it is also a typical friction pair that operates in harsh environments such as high speed, high temperature, and overload. The friction, lubrication and wear properties of the piston ring-cylinder liner play a decisive role in improving the reliability and durability of the internal combustion engine and ensuring the economical and reliable operation of the internal combustion engine. The research on its tribology has always been one of the hot spots that people pay attention to. However, due to the complexity of piston ring-liner tribo...
