Heavy-load permanent magnet suspension bearing suitable for hydro-generator

The invention discloses a heavy-load permanent magnet suspension bearing suitable for a hydro-generator. The thrust bearing is mainly composed of a thrust inner shaft washer, a thrust inner shaft washer rotating disc, an upper end cover, an outer race, an outer magnetic conductive ring, a lower end cover, a radial protection auxiliary bearing, an auxiliary bearing seat, a rotating disc fixing ring, an axial protection auxiliary bearing, a rotor axial magnetizing permanent magnet ring, a magnetism isolating ring and a stator axial magnetizing permanent magnet ring. The thrust bearing is designed to be similar to a thrust rolling bearing in rolling bearings, a turntable bearing, a thrust sliding bearing in sliding bearings and other mechanical thrust bearings, the bearing capacity range can reach ten tons, tens of tons, hundreds of tons and even thousands of tons, and the thrust bearing can replace the thrust rolling bearing, the turntable bearing, the thrust sliding bearing and other mechanical thrust bearings
