jaw type broken machine in dressing equipment in the bear with various ore and chunks material of medium grain degrees broken
jaw type broken machine of each a parts are is is important of, dressing equipment on main pew jaw crusher bearing of concern is special rigorous of, jaw type broken machine of main bearing mostly used outside type bearing, bearing within lining mostly is by BA's alloy made, this bearing scraping Institute technology requirements high, Scraping Institute bad or clearance adjustment improper, will led to Institute w or burn w accident, now we from top clearance, and side clearance, and axis to clearance of analysis to discussion a
hj series jaw crusher bearing clearance of measurement method:
1, and top clearance of measurement method
top clearance of height available increase or decrease bearing joints at w mouth gasket of thickness to adjustment, gasket number more less, bearing pressure real situation more good, equipment run more smooth, so in guarantee not appeared burn w of situation Xia, gasket more less more good, Tip clearance measurement lead is usually used to measure.
2, side clearance measurements
backlash between the bearing and shaft, usually using feeler gauges to measure. When measuring feeler gauge inserted into the clearance shall be not less than the length of diameter of one-fourth, bearing joint face backlash should be uniformly equal.
3,bearing radial clearance axial clearance measurement method of measuring General racing lead foot measurement and pressure measurement method in two ways.
(1) match measurement method: for the larger diameter bearings, a large gap between them, with narrow feeler gauge direct detection. For smaller diameters of bearings, a small gap between them, use feeler gauges to measure the inconvenience, but the lateral clearance of the bearing, you must use appropriate thickness feeler gauge to measure.
(2) measurements of lead: lead detection assay for detection of bearing clearance with a feeler gauge pressure is accurate, but more trouble. Aluminum wire used for testing should be soft, not too large or too small in diameter, the ideal diameter is 1.5~2 times the gap, practical work are usually tested using a soft wire. Above, the
gap measuring method, after many years of practice stars heavy industry think tip clearance of the bearing for shaft diameters of 0.15%~0.2%, 60%~100% of side clearance for the top slot, axial clearance should be 1~3mm is the best.
