Engine test bed exhaust system

Abstract

The invention discloses an engine test bed exhaust system comprising a swing reduction motor, a telescoping reduction motor and an exhaust swing tube. The output shaft end of the swing reduction motor is sleeved with a small gear; the small gear meshes with a large gear in the horizontal direction; the large gear sleeves a swing tube spindle; a swing platform is provided on the top of the swing tube spindle; the exhaust swing tube comprises an exhaust fixed tube, a bend segment, a telescopic hose and a telescopic segment rigid tube which are connected in sequence; the telescoping reduction motor is mounted under the telescopic segment rigid tube; a linear guide assembly is mounted on the telescopic segment rigid tube; racks are evenly distributed on the linear guide assembly; one end of the telescoping reduction motor drives a gear to rotate and mesh with the racks above; the telescoping reduction gear is fixed on a support bed-top; the swing platform supports the bend segment of the exhaust swing tube. The engine test bed exhaust system allows quick butt joint of an exhaust line and a test engine and allows smooth exhausting, test preparation time is greatly shortened, and utilization rate of a test bed is increased.

Description

technical field [0001] The invention relates to an engine test bench exhaust system. Background technique [0002] When the engine leaves the factory for bench performance tests, it is necessary to manually connect multiple pipes such as engine cooling water, fuel oil, engine oil, air intake, supercharged intercooler, and drain pipes. To realize the connection of oil, water, gas, electricity and the test engine requires a lot of The time is low, and the efficiency is low. If the engine exhaust pipe is not connected correctly, there will be air leakage, which will lead to inaccurate test results. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fast and efficient engine test bench exhaust system. [0004] The technical scheme adopted in the present invention is: [0005] Engine test bench exhaust system, the exhaust system i...
