Abstract

급격한 브레이크로 인한, 클러치판의 회전관성력에 의한 충격력이 보조모터로부터의 회전전달부에 전해지지 않고, 회전정지중의 보조모터로부터의 회전전달부의 덜거덕거림 등이 모터풀리의 회전방향 덜거덕거림으로서 전해지지 않고, 고속운전으로부터 저속운전으로 이행시킬 경우의 브레이크판과 클러치판의 사이에 미끄러짐이 발생하지 않도록 하고, 보조모터의 토르크전달효율을 안정시키고, 정비성도 좋게 한다.The impact force by the rotational inertia force of the clutch plate due to the sudden brake is not transmitted to the rotation transmission part from the auxiliary motor, but the rattling of the rotation transmission part from the auxiliary motor during rotation stop is transmitted as the rotation direction of the motor pulley is rattling. Without slipping, slippage does not occur between the brake plate and the clutch plate in the case of shifting from high speed operation to low speed operation, and the torque transmission efficiency of the auxiliary motor is stabilized, and the maintainability is also improved.

클러치판(31)을, 플라이휠(55) 또는 회전부재(65)에 압접시켜서, 모터풀리(59)의 회전을 재봉기의 주축에 전달하는 재봉기의 구동장치에 있어서, 회전부재(65)을 직접제동하여 정지가능하게 하는 보조브레이크장치(81)를 구비한다. 보조모터(78) 및 회전전달장치(77)를 외부에 배치하고, 모터축(58)의 외단부에 접속한다. 회전전달장치(77)와 모터축(58)의 외단부와의 사이에, 로터(52)의 회전방향과 역방향으로 회전자유로운 일방향회전클러치(72)를 사이에 설치한다.In the sewing machine drive device which presses the clutch plate 31 to the flywheel 55 or the rotating member 65 to transmit the rotation of the motor pulley 59 to the main shaft of the sewing machine, the rotating member 65 is directly braked. It is provided with an auxiliary brake device 81 to be stopped by. The auxiliary motor 78 and the rotation transmission device 77 are disposed outside and connected to the outer end of the motor shaft 58. Between the rotation transmission device 77 and the outer end of the motor shaft 58, a one-way rotation clutch 72 which is free to rotate in the opposite direction to the rotation direction of the rotor 52 is provided therebetween.
