Abstract

재봉기의 구동장치에 있어서, 모터레버(61)는, 모터샤프트(58)와 일체로된 클러치플레이트(61)가 모터샤프트의 주위를 회전할 수 있고 보조모터(75)의 회전이 그곳에 적용되는 주모터 또는 회전부재(65)의 로터(52)와 일체로된 플라이휠(55)에 대향하여 푸쉬되도록 작동되며, 이것에 의해 모터샤프트(58)의 외측단부상에 단단히 장착된 모터풀리(59)의 회전이 무단벨트를 통해 재봉기의 스핀들에 전달된다; 보조브레이크장치(81)는 회전부재(65)를 직접 제동시켜 정지시킨다.In the driving device of the sewing machine, the motor lever 61 is a main shaft in which the clutch plate 61 integrated with the motor shaft 58 can rotate around the motor shaft and the rotation of the auxiliary motor 75 is applied thereto. Of the motor pulley 59 firmly mounted on the outer end of the motor shaft 58, thereby being pushed against the flywheel 55 integrally with the rotor 52 of the motor or rotating member 65. Rotation is transmitted to the sewing machine spindle via endless belts; The auxiliary brake device 81 stops by directly braking the rotating member 65.
