Gear assembly and gear combination

The invention relates to the technical field of gears, in particular to a gear assembly and a gear combination. The gear assembly comprises at least a first gear and a second gear which have the samesize and are coaxially arranged, and the first gear and the second gear comprise a plurality of first gear teeth and a plurality of second gear teeth which are elastically arranged in a staggered manner. When the first gear teeth and/or the second gear teeth are stressed, included angles between the first gear teeth and the second gear teeth change. When the gear assembly is meshed with other gears, the gear assembly is stressed by other gears, the included angles between the first gear teeth and the second gear teeth change, the first gear teeth are in meshed transmission with other gears, the second gear teeth are in pressure contact with other gears, the gear teeth in pressure contact eliminate backlash between the gear teeth during gear meshed transmission, non-backlash transmission isachieved, the phenomenon that noise or abnormal sound is generated during transmission of the gear assembly is avoided, meanwhile, after transmission of the gear assembly is completed, non-backlash meshing is kept between the gear assembly and other gears, and the transmission precision of the gear assembly is further improved.
