CONJUNTO DE ACIONAMENTO PARA O AGITADOR DE UMA MAQUINA DE LAVAR,METODO DE CONVERTER MOVIMENTO ROTATIVO CONTINUO EM OSCILACAO CICLICA,METODO DE OSCILAR UM AGITADOR E TRANSMISSAO

摘要

A compact transmission for an automatic washer which converts unidirectional rotary motion to oscillating rotary motion without the use of gears is provided. An input shaft is rotatingly driven by an electric motor and has a reversing thread connection to an intermediate member through a thread follower to cause the intermediate member, which is restrained against rotation, to reciprocate vertically. The intermediate member has an angled cam slot and follower connection with an output shaft which results in oscillating rotary motion of the output shaft. The drive member can be carried on the outside of the coaxial input and output shafts or can be sandwiched between the output shaft and coaxial, nested input shaft.
