The invention relates to a transmission shaft assembly for a permanent magnet suspension bearing support. The transmission shaft assembly comprises a support assembly and a transmission shaft. The support assembly is composed of a support shell and a permanent magnet suspension bearing. The permanent magnet suspension bearing is composed of an outer ring ferrule, an inner ring ferrule, an outer permanent magnet ring, an inner permanent magnet ring and an axial locating thrust bearing. The permanent magnet suspension bearing is arranged in the support shell in the support assembly in a sleeved mode through an outer ring of the outer ring ferrule in the permanent magnet suspension bearing and fixed together through vulcanized rubber to form the support assembly. The permanent magnet suspension bearing is arranged on the transmission shaft in a sleeved mode through an inner ring of the axial locating thrust bearing in the permanent magnet suspension bearing, and connected and fixed in an interference fit mode. The transmission shaft assembly has the advantages that compared with a traditional ball bearing, mechanical contact of the permanent magnet suspension bearing is avoided, a rotor can operate at a high rotating speed, mechanical abrasion is small, energy consumption is low, noise is low, the service life is long, lubricating is not needed, and oil pollution is avoided.
