Technical Field

The invention relates to a detection tool, in particular to a dynamic balance detection clamp of a balance shaft.

Background

The balance shaft is one of the key parts of the engine of the large-displacement motorcycle, and the service life of the motorcycle is directly influenced by the performance of the balance shaft. The strong vibration generated when the engine is operated not only makes the driver feel uncomfortable, but also accelerates the aging degree of each component. The unbalance of the balance shaft of the engine is a main reason for the vibration overrun of the engine during test run, so the dynamic balance detection of the balance shaft is particularly important.
