我厂资料室有一台天津产的CDOGX65型晒图机,在一次维修保养过程中,因玻璃滚筒的帆布传动带清洗后,产生收缩变形,致使该机只用了一周后,玻璃滚筒即破碎。该滚筒长约1m,壁厚约5mm,每根200元左右,且远在天津。为此,对该机故障原因进行了观察分析,发现主要原因是:(1)因传动带长度不足,以致玻璃滚筒与灯管不同心(偏心约15mm)。(2)传动主轴弯曲变形,径向跳动严重(径向跳动5mm)。玻璃滚筒受灯管加热,温度较高,受传动带径向压力
I plant a reference room has a production of CDOGX65 tanning machine in Tianjin, in a maintenance process, due to glass drum canvas belt cleaning, resulting in shrinkage deformation, resulting in the machine only a week later, the glass roller is broken. The drum length of about 1m, wall thickness of about 5mm, about 200 yuan each, and far in Tianjin. To this end, the cause of the aircraft were observed and analyzed the causes and found that the main reasons are: (1) due to the lack of length of the belt, so that the glass tube and the tube is not the heart (eccentric about 15mm). (2) transmission spindle bending deformation, radial runout serious (radial runout 5mm). Glass tube heated by the lamp, the temperature is higher, by the radial belt pressure
