An automobile tensioner testing machine

Abstract

The invention provides an automobile tensioning wheel testing machine. A shaft sleeve is installed in a tensioning wheel. The automobile tensioning wheel testing machine comprises a driving unit, an eccentric swing mechanism and a testing unit; the eccentric swing mechanism comprises a main shaft, a supporting base and an eccentric mechanism, wherein the main shaft is provided with the supportingbase, and one end of the main shaft is connected to the driving unit; at least one eccentric mechanism is fixed on the main shaft, and the eccentric mechanism is eccentrically rotated by the rotationof the main shaft; the testing unit comprises a small wheel, a bracket and a tensioning wheel main shaft, wherein the tensioning wheel main shaft is coupled to a sleeve revolute pair in the tensioningwheel, and the small wheel is mounted on the outer casing of the tensioning wheel; the testing unit is located in a radial direction of the eccentric mechanism, and the eccentric mechanism is connected to the small wheel through a steel rope. The automobile tensioning wheel testing machine implements high-frequency reciprocating push-pull on the tensioning wheel, so that the tensioning pulley main shaft and the sleeve are rubbed to achieve a separate test on the life of the shaft sleeve, and at the same time simulate the vehicle in muddy road conditions and the high temperature environment close to the engine.

Description

technical field [0001] The invention relates to the field of testing tension wheels for automobiles, in particular to an automobile tension wheel testing machine. Background technique [0002] The tensioner plays a decisive role in the stability of the steam transmission, and it is very easy to be damaged. The main reason is that the inner sleeve and the shaft wear each other during operation, which leads to the failure of the main shaft due to the large inclination angle. High temperature is also a great test for the performance of the bushing. Existing tensioner testing machines currently on the market are mainly aimed at the system test of the tensioner, and the failure of the tensioner is often caused by the failure of the axle sleeve in the tensioner. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an automobile tensioner testing machine, which implements high-frequency reciprocating push-pull on the tens...
