Plastic-steel bearing for rotor shaft of cooling blower consists of hollow-cylindrical part with conical seat having projecting flange to snap into groove of shaft when fitted into part

摘要

The bearing assembly consists of a hollow cylindrical part (11) with a larger-diameter conical seat (12). The seat has a recess (121) and the part has a hollow (13) with an upward extending edge, which forms a flange (14). When the bearing is fitted into the blade (26), the rotor shaft (262) is fitted into the hollow and the flange snaps into a round groove (265) in the shaft to limit its movement. A cable clip is inserted to retain the upper stop of the rotor shaft.
