Engine chain system tightener plunger displacement measurement device and measurement method

Abstract

The invention provides an engine chain system tightener plunger displacement measurement device and a measurement method. The measurement device comprises a data acquisition processor, a computer, a tightening rail, a tightening rail support for supporting the tightening rail, a metal conductor arranged on the tightening rail support, and a displacement sensor fixed on the side cover of the engine, wherein the tightener plunger ejects against the tightening rail; and the data acquisition processor is respectively electrically connected with the displacement sensor and the computer. The tightener plunger displacement fluctuation condition of the engine timing chain in different working conditions can be detected in real time, the working condition of the measured chain system is further known, the working performance of the engine tightener is checked, and guarantee is provided for meeting high-performance requirements of the engine.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a measuring device and a measuring method for detecting the displacement of a plunger of a timing chain system tensioner during engine operation. Background technique [0002] The tensioner is a commonly used holding device on the timing system of the automobile engine. The function of the tensioner is to keep the timing chain at a relatively stable tension during the transmission process, and at the same time it can absorb and compensate the impact of the chain during the working process. The expansion and contraction caused by force deformation and other reasons. In this way, failure problems such as tooth skipping or tooth loss of the timing chain can be avoided, and the vibration amplitude and noise of the chain can be reduced, and the wear of the sprocket and the chain can be reduced. [0003] The structure of the tensioner is various, mainly divided into hyd...
