Power transmission device for sewing machine

缝纫机的动力传动装置

Abstract

The utility model discloses a power transmission device for a sewing machine, which comprises an upper shaft transmission mechanism, a lower shaft transmission mechanism, a control line transmission mechanism, a transmission belt and a tension adjusting mechanism, wherein the upper shaft transmission mechanism contains an upper transmission shaft and a first belt pulley; the lower shaft transmission mechanism contains a lower transmission shaft and a second belt pulley; the control line transmission mechanism contains a control line transmission shaft and a third belt pulley; the transmission belt is simultaneously sleeved with the first belt pulley, the second belt pulley and the third belt pulley; and the tension adjusting mechanism contains an idle pulley for pressing the transmission belt to control the tension of the transmission belt and is arranged correspondingly to the sides of any two belt pulleys. Thereby, the utility model can improve the assembly easiness of each transmission shaft and the belt and greatly reduce the intrusive noise generated by dithering during the operation process of the belt.
本实用新型公开了一种缝纫机的动力传动装置,其包括有上轴传动机构、下轴传动机构、控线传动机构、传动皮带及张力调整机构,上轴传动机构包含上传动轴及第一皮带轮;下轴传动机构包含下传动轴及第二皮带轮;控线传动机构包含控线传动轴及第三皮带轮;传动皮带同时套接在第一、二及三皮带轮;张力调整机构对应任二皮带轮侧边安置,且其包含压掣传动皮带以控制其张力的惰轮。借此,可提高各传动轴与皮带组装容易度,且能大幅度地降低皮带运转过程中因抖动而产生的扰人噪音。
