850初轧机主联轴节是采用半圆滑块式。磷青铜滑块在严重的冲击载荷和极大的工作压力下工作,联轴倾角达7°左右,轧机端的联轴节还受高温、铁鳞和水份、灰尘的侵袭,滑块的平面和圆弧表面产生严重的磨损,寿命只有两个月,且增大了间隙,加大冲击载荷,使联接轴扭震增大,叉头磨损和变形,轧辊也经常掰断扁头。 850 primary rolling mill main shaft is the use of semi-circular slider. Phosphor bronze slide block work under severe impact load and great working pressure, coupling angle of about 7 °, the end of the rolling mill joints are also subject to high temperature, scale and moisture, the invasion of dust, the slider plane and Serious wear and tear on the arc surface, life expectancy is only two months, and increased clearance, increase the impact load, the coupling shaft increased torsional vibration, fork wear and deformation, the roll is also often breaking the flat head.
