The invention relates to the technical field of bearing auxiliary equipment, and discloses a rotary
drying device for cleaning inner and outer rings of a bearing. The rotary
drying device comprises amachine body, a bearing inlet and outlet, dryers and soaking pools, wherein a set of rotating discs of disc-shaped structures are arranged in the middle of the
machine body, a set of soaking pools with the
diameter larger than that of the rotating discs are arranged on the lower sides of the rotating discs, four sets of same cleaning grooves are annularly and fixedly formed in the rotating discs at equal intervals, and vertical sleeve rods with the diameters gradually reduced are fixedly installed at the centers of the cleaning grooves upwards through electric lifting rods; and vertical air dispersing pipes are fixedly installed in the sleeve rods, a set of dryers are fixedly installed on the right side of the top of the
machine body, the left sides of the dryers communicate with hot air cavities fixed to the upper side and the lower side of the middle of the interior of the
machine body through air pipes, and the left sides of the dryers communicate with a plurality of sets of air injection rows with openings facing the sleeve rods. The rotary
drying device has the advantages that the inner and outer rings are cleaned and dried at the same time, the speed is high, the efficiency is high, automatic operation is achieved, and popularization and use are facilitated.
