新出厂的V型镇压器,两端轴架与镇压轮之间各有33.5毫米空隙,空隙中间安装有厚度为23毫米的夹子,夹子两端各有5.25毫米的间隙(如图)。夹子内侧间隙的作用是既可保证镇压轮与轴一同共转,又能使单个镇压轮遇到阻力时绕轴自转;夹子外侧间隙的作用是保证镇压器轴在向两端窜动时不和防尘帽相碰。镇压器轴头露出轴承架外30毫米,而防尘帽内腔深度为40毫米,所以轴头距防尘帽有10毫米间隙。 The new V-Press, with 33.5 mm clearance between each end bracket and the pinch wheel, has a 23 mm-thick clip in the middle of the gap, and a 5.25 mm clearance at each end of the clip (pictured). The role of the gap inside the clip is to ensure both the co-rotation of the pinch wheel with the shaft, but also make a single anti-pressure wheel round the shaft resistance to rotation; clip outside the role of gap is to ensure that the roller axis in both ends of the movement and not Dust cap touch. Roller shaft head exposed 30 mm outside the bearing, and dust cap cavity depth of 40 mm, so the shaft head away from the dust cap 10 mm gap.
