DOUBLE FLANK WORM GEAR MECHANISM

摘要

A worm/worm gear assembly comprises a worm (12) having teeth (24) defined by at least one thread disposed thereon and a worm gear (14) having teeth (26) protruding from a surface thereof. At least one of the worm (12) and worm gear (14) is fabricated from a resilient material. The teeth (24) of the worm (12) and the teeth (26) of the worm gear (14) are interengaged and in a compressive relationship with each other to maintain double flank contact therebetween. At low- or no- load conditions, the double flank contact is made at the opposing outer edges of each teeth towards the center of the teeth. A method for delashing a gear system comprises disposing the worm (12) in mechanical communication with the worm gear (14) and loading the worm gear to cause the worm gear (14) to compressively engage the worm (12).
