Description
technical field [0001] The invention belongs to the field of processing large-scale static pressure bearings, and in particular relates to a processing device and a processing method of large-scale static pressure bearings. Background technique [0002] Type hydrostatic bearing is the core component in the hydroelectric generator, which plays the role of support and lubrication, and protects the normal operation of the rotating parts. The service life of the hydrostatic bearing directly determines the service life of the equipment. [0003] The volume of the pressure bearing is large, and the surfacing area of the inner hole of the static pressure bearing exceeds 1.5 square meters. There are several rectangular grooves on the inner wall of the static pressure bearing. The rectangular grooves are distributed along the circumferential direction of the static pressure bearing. Continuous surfacing welding is carried out on the inner side wall of the bearing body, and then the...
