ウォームとウォームホイールとの嵌合と探索について

Assembly using robots is a major challenge in factory automation. In this paper, we describe the meshing in a worm drive assembly undertaken by synchronizing the phase between the worm screw and the worm wheel. We analyzed and simulated the threshold (the distance by which the worm screw axis is moved toward the worm wheel) that can be considered as meshing success during the search for the synchronized phase between the meshing elements. We considered the phase between the worm screw and the worm wheel, the extent of the search for the phase suitable for meshing, the compensation for the threshold by applying a location-based function, and the notch and asymmetry of the worm wheel. The results of the simulation suggest that when a predetermined threshold is used to judge meshing, based on preconditions, there may be cases where the gear teeth overlap is low.
