Beschreibung
Zusammenfassung:	The backlash-adjustable worm helical gear transmission comprises a double-side special-shaped involute worm and a variable-tooth-thickness involute gear, the normal modules of the tooth faces on the two sides of the double-side special-shaped worm and the variable-tooth-thickness involute gear are equal, the end face modules of the tooth faces on the two sides of the double-side special-shaped worm and the variable-tooth-thickness involute gear are unequal, and the tooth faces on the two sides of the double-side special-shaped worm are involute helical faces of which the lead angles are unequal and the leads are equal, the helical angles of the tooth surfaces on the two sides of the variable-tooth-thickness involute gear are unequal and are positive values, so that the gradually-changed tooth thickness is generated, the design of the lead angles of the double-side special-shaped worm is met, and the modeling and meshing analysis method for backlash-adjustable worm helical gear transmission is provided.
