差动转把调速器是在径向实现差动缠绕大降速比省力传动。如图所示,其特征在于借助大、小绕线筒相对转动时,由钢绳进
Differential governor governor is in the radial differential winding to achieve greater speed than the labor-saving drive. As shown in the figure, it is characterized by the steel rope being moved by relative rotation of the large and small bobbins
