Abstract

PURPOSE:To prevent the entrance of a coating material into the screw hole of a boss part by a set screw and dispense with a screw exclusive for clogging the screw hole of the boss part to enhance facilitation of work and reduction in cost. CONSTITUTION:In assembling an impeller 10, a set screw having a specific resin 17 welded thereto is first spirally fitted to the screw hole 13 of the boss 11 of the impeller 10. Then, the impeller is fixed to a coating jig, and a coating material 18 is applied to the whole body of the impeller 10 having the set screw 15 as surface processing work. As the screw hole 13 of the boss 11 is masked by the set screw 15 in this case, the coating material 18 never enter into the screw hole. Successively, the impeller 10 is installed to the rotating shaft 8 of an electric motor 7, and the set screw 15 is spirally fitted to the screw hole 13 until the set screw 15 is fitted to a set screw fitting part. At this time, the specific resin 17 of the screw part is successively sent to the screw head part side from the screw part similarly to the first spiral fitting, the fitting can be certainly performed, and the fixation of the impeller 10 to the rotating shaft 8 is completed.

As explained above, the present invention includes an electric motor having a protruding rotating shaft having a locking screw fitting portion, and a screw hole that is drilled to communicate with the female fitting portion of the former rotating shaft. The impeller is equipped with an impeller with a boss part as the center of rotation, a set screw that is screwed into the threaded hole of the boss part, and a special resin fused to the threaded part of the set screw. By screwing a binary set screw into the screw hole and applying surface treatment to the impeller, the entire impeller with the set screw is painted, but the set screw does not fit into the screw hole of the boss. In addition to preventing paint from entering, the special resin prevents paint from adhering to the threaded part of the set screw, so there is no need to use a special thread to cover the threaded hole in the boss during surface treatment, making it easier to use. Not only is the work easier, but the product cost is also lower.

In addition, by fitting the surface-treated impeller to the rotating shaft of the motor and fitting the set screw into the set screw fitting part, the special resin on the set screw screw part prevents the screw from stopping. It is peeled off by the screwing action during the fitting process to the screw fitting part, and can be securely fixed with screws, so it can be directly attached to the impeller rotation shaft without replacing the screw after surface treatment as in conventional methods. This makes the fixing process faster and easier.
