Abstract

The invention discloses an engine valve-guide pipe strengthening abrasion simulation experiment machine. The engine valve-guide pipe strengthening abrasion simulation experiment machine comprises a first driving mechanism, a second driving mechanism, a valve, a guide pipe, a guide pipe clamp base, a heating device, a friction resistance measuring device and a load loading device. A clamping head is fixedly arranged on an output shaft of the first driving mechanism so as to drive the valve to rotate. One end of the valve is installed on the clamping head. The other end of the valve is connected with the friction resistance measuring device. The valve is sleeved with the guide pipe, and the guide pipe is fixedly connected with the guide pipe clamp base. The second driving mechanism is fixedly connected with the guide pipe clamp base. The load loading device is connected with the guide pipe clamp base. The heating device covers the guide pipe clamp base so as to heat the valve and the guide pipe. According to the engine valve-guide pipe strengthening abrasion simulation experiment machine, the engine valve-guide pipe friction pair motion mode is simulated, the strengthening abrasion experiment is achieved, the experiment period is shortened, and experiment equipment is provided for evaluating the service life of a friction pair.

Description

technical field [0001] The invention relates to the technical field of wear simulation experiments, in particular to an engine valve-duct enhanced wear simulation test machine. Background technique [0002] Engine valves work in the environment of high temperature, corrosion and impact contact conditions, so the life of the valve is the main part that restricts the performance and life of the engine. However, the life evaluation equipment of an important friction pair valve-guide which is matched with the engine valve is still blank so far. With the development of gas engines, the operating temperature and lubricity between valves and guides are far worse than those of fuel engines; its tribological performance evaluation technology directly affects the material composition design, preparation process design and matching selection of valves or guides and other key technical links. [0003] At present, the life evaluation test of the engine valve-guide is carried out on the...
