Engine running-in test bench

Abstract

The invention belongs to the technical field of engines, and particularly discloses an engine running-in test bed which comprises a motor, a gearbox, an engine, a supporting frame, a base of the supporting frame, a cooling liquid circulation system and a strong exhaust fan. The motor and the gearbox are connected and installed on the motor support, the motor support is connected with the base through the guide columns, a hydraulic jacking mechanism is further arranged at the bottom of the motor support, and the bottom of the hydraulic jacking mechanism is fixedly connected with the base. The engine is connected with the gearbox. The engine is fixedly connected with the base through the engine support. The engine support is composed of two symmetrical L-shaped supports, two parallel dovetail sliding grooves are formed in the base, trapezoidal sliding blocks are arranged in the dovetail sliding grooves, the bottom of the engine support is matched and locked with threaded holes of the trapezoidal sliding blocks through bolts, and a plurality of kidney-shaped holes are formed in the top of the engine support. The engine running-in test device meets running-in tests of engines of different specifications and models, and is easy to operate, convenient to move and high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine running-in test bench. Background technique [0002] After the engine is repaired and assembled, in order to check and eliminate the defects in the assembly and adjust each mechanism to be in the best state, so that the engine has good power, economy and reliability, the factory test is generally carried out on the overhauled engine. Run-in test bench for inspection. [0003] Existing cold running-in devices for engines are all made for a specific vehicle type and can only be cold ground in a fixed shape. They are bulky, expensive, and inconvenient to move, which not only brings inconvenience to maintenance owners, but also limits the types of maintenance engines. If the maintenance owner wants to expand the scope of maintenance, he needs to purchase or manufacture all kinds of engine cold running-in devices, which is not only expensive, but also takes up a...
