现将快速装卸皮带轮的结构作一介绍。皮带轮与轴的装配形式如图所示。锥套和轮毂的锥度为1:25,锥套大端直径略大于锥孔大端直径0.5～1毫米,锥套孔尺寸比轴颈尺寸大0.1毫米左右,锥套做成单开口式。皮带轮在装配时旋转顶丝3,当顶丝到达锥套上之半丝扣底部时,由于继续旋转顶丝3,在带轮上的半丝扣的作用下,使皮带轮与锥孔产生轴向位移,并通过内锥面使开口锥套束紧,从而实现过盈配合,以传递扭矩。
Now the structure of the quick loading and unloading pulley made an introduction. Pulley and shaft assembly form as shown. Cone and hub taper 1:25, large diameter taper sleeve slightly larger than the large end of the cone diameter of 0.5 to 1 mm, taper hole size than the journal size of about 0.1 mm, made of single-ended taper sleeve. 3, when the top wire reaches the bottom half of the threaded sleeve on the tapered sleeve, as the top wire 3 continues to rotate, the pulley and the tapered hole are axially displaced by the semi-threaded buckle on the pulley Displacement, and the cone through the inner cone taper sleeve tight, in order to achieve interference fit, in order to transmit torque.
