在大搞技术革新和技术革命运动中,风缸常是不可缺少的。对于非标准风缸的皮碗,我们试用了一种代用品——三角皮带环,效果较好。其结构如图1所示。三角皮带环可用任何型号的新旧三角皮带,只要完整无缺即可。为了使三角皮带环严密,其接头须错开,如图2所示。同时,三角皮带环槽的两侧作 In the vigorous technical innovation and technological revolution movement, the cylinder is often indispensable. For non-standard cylinder cup, we have tried a substitute - V-belt loop, the better. The structure shown in Figure 1. V-belt can be any type of new and old V-belt, as long as intact can be.
