Abstract

The invention discloses an engine rotational inertia measuring device. The engine rotational inertia measuring device comprises a machine body, a driving mechanism, a belt transmission assembly and aconnecting flange connected with an output end flange of an engine to be measured; the machine body comprises two adjacently arranged bases and three supporting seats; the driving mechanism comprisesa motor and a reducer which are connected in a transmission mode, and is placed on the bases and the supporting seats; the belt transmission assembly comprises a belt transmission mechanism, a belt tensioning mechanism and two rotating shafts, the two rotating shafts can be rotatably connected with two belt pulleys and the belt tensioning mechanism through four bearings, the first rotating shaft is coaxially and fixedly connected with the output end of the reducer, and the second rotating shaft is fixedly disposed at the center of the connecting flange. The power output by the driving mechanism can be transmitted to the output end flange of the engine to be measured under the action of the belt transmission assembly, and by measuring the change conditions of the rotational speed torque ofan engine output shaft, the rotational inertia of the engine to be measured can be accurately measured. The engine rotational inertia measuring device has a compact structure, convenient assembly anddisassembly, high practicability and convenient popularization and use.

Description

technical field [0001] The invention relates to the technical field of industrial test and evaluation, in particular to a device for on-site measurement of the overall moment of inertia of the rotary moving parts of the engine. Background technique [0002] At present, the detection and evaluation of engine performance at home and abroad are mostly completed in special engine laboratories, which require special instruments, equipment and venues, and the test period is long and the cost is high. No-load dynamometer technology is a detection method that can quickly, conveniently and accurately evaluate the performance of the engine. It can detect the working condition of the engine without transporting it from the workplace to the laboratory. [0003] The moment of inertia of the engine is not only a key parameter necessary for the no-load dynamometer of the engine, but also a necessary parameter for obtaining the instantaneous torque of the engine, the compression pressure of...
