Problems solved by technology

Although there are currently detection devices related to rotational torque and roundness, the two are often separated and occupy a large space. At present, no device that can integrate the above two functions and has a better detection effect has been found.
Especially when it is necessary to measure the roundness of a certain section of the shaft, it is currently impossible to achieve automatic measurement

Abstract

The invention discloses an automatic measuring device for a gyroscopic moment of a crankshaft and a roundness of a rotation shaft in an engine. The automatic measuring device comprises a driving motor, a gearbox, a gearbox support, a rotation shaft connector, a torque sensor, rolling bearings, a rolling bearing support, the rotation shaft, a connecting sleeve, and a roundness detection assembly. The roundness detection assembly comprises a detection support, a detection rod, a detection rod spring, a varistor, and a pressure display recorder. The detection support is distributed around the periphery of the rotation shaft. According to the automatic measuring device for the gyroscopic moment of the crankshaft and the roundness of the rotation shaft in the engine, the gyroscopic moment of the crankshaft and the roundness of the rotation shaft are accurately detected, and the using effect is good.

Description

technical field [0001] The invention relates to the technical field of engine detection devices, in particular to an automatic measuring device for engine crankshaft turning torque and rotating shaft roundness. Background technique [0002] At present, when the engine is installed on the assembly line, it is necessary to measure the rotational torque of the engine crankshaft and the roundness of the engine shaft. In actual operation, it is mostly measured by workers, with large errors and heavy workload. Although there are detection devices related to rotational torque and roundness at present, the two are often separated and occupy a large space. So far, no device that can integrate the above two functions and has a better detection effect has been found. Especially when it is necessary to measure the roundness of a certain section of the rotating shaft, automatic measurement cannot be realized at present. [0003] The disclosure of the above background technical content i...
