LOCATION STABILIZING STRUCTURE FOR ENCLOSURE-TYPE ROTARY SHAFT

摘要

A location stabilizing structure for enclosure-type rotary shaft includes a fitting member having an enclosure section and a shaft member having a shaft rod tightly enclosed in the enclosure section. The enclosure section has multiple inner adaptive faces. The shaft rod has multiple outer adaptive faces in adaptation to the inner adaptive faces for matching the inner adaptive faces. The number of matching inner adaptive faces and outer adaptive faces is varied with the change of angular position between the enclosure section and the shaft rod. The locating/stabilizing structure is designed with different numbers of matching inner and outer adaptive faces indifferent angular positions to provide different locating force. Indifferent angular positions, the unmatching inner adaptive faces and outer adaptive faces interfere with each other to provide radial elastic compressing force to securely locate the rotary shaft and avoid loosening or swinging.
