我厂的造纸机总轴,由于要求网部、压榨部、烘缸部运转速度有少量差别,为此在各部都装了调速器进行微调。过去,调速器由垫圈(图1)决定轴向位置,但定位不理想,容易造成三角皮带从惰轮上跑偏脱落。要纠正这种现象,则必须改变轴承位置,费时费力。后来,我们加工了一批可调厚度的垫圈,解决了定位问题。图2是以细牙螺纹可调厚度垫圈的结构;在活动垫圈上的M10螺纹有两种作用:1)便于搬旋;2)避 I plant the total shaft of the paper machine, due to the requirements of the Ministry of network, press section, dryer section operating speed there are a few differences, for which all ministries are equipped with a governor for fine-tuning. In the past, the governor washer (Figure 1) determines the axial position, but the positioning is not ideal, likely to cause the V-belt run away from the idler. To correct this phenomenon, you must change the bearing position, time-consuming and laborious. Later, we processed a number of adjustable thickness washers to solve the positioning problem. Figure 2 is a thin thread thickness adjustable washer structure; M10 thread in the washer activities have two roles: 1) easy to move; 2) to avoid
