Problems solved by technology

[0002] At present, in the process of research and development of automobile engines, it is necessary to carry out online simulation tests to test its various performance parameters. In the actual tests of various parameters, we found that the engine and the main shaft drag There is a lack of an effective docking rotation structure when the mechanism is docked, and the transmission mechanism of the prior art has low docking efficiency, or cannot detect engine power, or has defects such as small transmission torque and low transmission efficiency, resulting in inaccurate follow-up test data

Abstract

Provided is an engine butt-joint and rotation mechanism with a detection function. The mechanism comprises a driving motor arranged on a test platform; the driving motor is, through a coupling, in shaft connection with one end of a bearing seat group arranged on the test platform and composed of two bearing seats which are arranged side by side and coaxially connected; the other end of the bearing seat group is in shaft connection with a spline provided with a positioning cylinder at the lower part through an elastic coupling; a torque detection device is arranged at the bearing seat group, one end of a weight suspension rod of the torque detection device is sleeved on a shaft between the two bearing seats, an adjusting weight is hung at the other end of the weight suspension rod, and a torque sensor is arranged on a shaft between the bearing seat group and the coupling; and the driving motor, the coupling, the bearing seat group, the elastic coupling and the spline are coaxially connected. The engine butt-joint and rotation mechanism with a detection function enables an engine and a main shaft dragging mechanism to be in butt joint with each other so as to drive the engine to rotate, can be used for detecting the power of the engine in real time and adjusting pressure and is applicable to the field of cold test of a variety of engines.

Description

technical field [0001] The invention relates to a docking and rotating structure, in particular to a docking and rotating structure for docking an engine with a main shaft driving mechanism and driving the engine to rotate, which is used in engine cold testing. Background technique [0002] At present, in the process of research and development of automobile engines, it is necessary to carry out online simulation tests to test its various performance parameters. In the actual tests of various parameters, we found that the engine and the main shaft drag There is a lack of an effective docking rotation structure when the mechanism is docked, and the transmission mechanism of the prior art has low docking efficiency, or cannot detect engine power, or has defects such as small transmission torque and low transmission efficiency, resulting in inaccurate follow-up test data . [0003] Now there is a need for a docking and rotating structure that can connect the engine to the main...
