Abstract

The invention discloses an outboard propulsion engine comprehensive performance test bed and test method and an outboard propulsion engine comprehensive performance test bed centering method. The problem that in the prior art, a propeller output shaft is liable to fracture and is difficult to center is solved. The test bed, the test method and the centering method have the beneficial effects thata true working water environment of an outboard propulsion engine can be accurately simulated and a fatigue fracture risk of the propeller output shaft can be reduced. According to the scheme, the outboard propulsion engine comprehensive performance test bed comprises an inner water tank which is used for simulating a working water environment of the outboard propulsion engine, wherein the inner water tank is set in an outer water tank and protrudes out of the outer water tank; the inner water tank is equipped with a water outlet communicated with the outer water tank; the outboard propulsionengine can be set in the inner water tank; the outboard propulsion engine is connected with a fixing frame; the propeller output shaft of the outboard propulsion engine is connected with a power transmission shaft; and the power transmission shaft passes through the inner water tank and is connected with a dynamometer.

Description

technical field [0001] The invention relates to the technical field of outboard motors, in particular to an outboard motor comprehensive performance test bench, a centering method and a test method. Background technique [0002] The operating conditions of the outboard engine (main engine) are different from those of the land engine. The outboard engine (main engine) mainly uses the propulsion characteristics of the engine. The load to be applied to assess the performance of the outboard engine is determined by the matching propeller. The performance assessment of the land engine Mainly external characteristics; the layout of the outboard motor (main engine) has vertical axis placement and horizontal placement, and the performance of the outboard motor needs to be tested in the form of a complete machine (outboard motor and bottom assembly) to test the output shaft power of the propeller. The working environment and working mode of the external machine engine (main engine), ...
