Background
Engines play an important role in various power machines such as airplanes and ships, and the magnitude of output torque directly influences safe operation of vehicles. For a mechanical device or a workpiece outputting a rotating motion, whether the output torque is stable or not is an important index representing the working quality of the mechanical device or the workpiece. For example, the balance shaft can achieve ideal clearance between the crankshaft and the balance shaft gear engagement under the condition of fixed and reliable torque feedback after the crankshaft of the engine is driven positively and negatively, so that the output torque of the crankshaft needs to be measured in the assembly process of the engine.
The conventional engine torque passive test is a process that a motor drives a tested shaft to rotate and a main shaft transmits the torque of a tested generator to a detection device. In the torque transmission process, the axle center of the tested engine, the axle center of the sensor and the main shaft are required to be positioned on the same horizontal line so as to reduce the extra moment caused by eccentricity. However, in the conventional coping manner, couplings are installed at two ends of the torque sensor to improve the coaxiality of the two ends of the torque sensor, but the couplings have good alignment function only in a static state, and when the torque test with high power is performed, the rapid rotation of the connection part may slightly deform the end of the sensor, so that the input and output shafts are interfered by bending moment, and the output value of the coupling is affected and deviates from the true value.
Therefore, the invention provides output torque dynamometer for an engine.
