Description

Technical Field

[0001] The present application relates to the technical field of shaft detection, and specifically to a detection device for a power output shaft of a harvester. Background Art

[0002] When inspecting agricultural machinery, the quality of the power take-off (PTO) shaft significantly impacts its performance. This is especially true for harvesters and other agricultural equipment, where the shaft's rotational performance and coaxiality are directly linked to operational stability and harvesting efficiency. PTO shafts are typically subjected to significant impact and load during operation, making them susceptible to eccentricity, wear, and vibration, impacting the equipment's overall performance. Therefore, inspecting PTO shafts is crucial. By testing their coaxiality, roundness, and surface properties, we can effectively assess and control their performance and minimize potential malfunctions.
