Technical Field

The invention relates to the technical field of transmission shafts, in particular to a pressure self-adaptive transmission shaft.

Background

The general development trend of modern AC transmission control systems is intellectualization, modularization, digitalization and high frequency.

The existing pressure self-adaptive transmission shaft has certain defects, and has no self-lubricating function in the use process, so that the shaft body is easily seriously abraded after the use time is long, the use is influenced, and the production cost of an enterprise is improved.
