Familiar lime production line friends all know, lime kiln spring plate ears and big ears ring gear rim with pin connections. Pin and the ears of the holes in the device after a long run after the emergence of wear, and even bore grinding flat, pin loose, the ring gear paragraphs loose, causing the kiln body vibration. Then the lime kiln pins and holes in the ears frayed how to do it? Lime kiln ring gear on the scene with the pin boring process, we must practice in the specific attention to the following aspects: First, the diameter of the bore size, except by the ears dislocation, the impact of hole wear, but also by the size of the original manufacturer ears sub constraints. If a large amount of dislocation, and wear, the ears can not meet the pore size requirements allowing the pin aperture appropriate to reduce the contact area, as long as the contact area proved greater than 70%, the effect is good ears sub dislocation alignment can also be used spring pull method, be alignment. Secondly, the boring bar produced according to the size of the aperture, to maintain its rigidity sufficient to prevent the taper boring a hole appears. Finally, the required tools and instruments and equipment: homemade top wire 8, Dry type magnetic separator pulling screws 8. 1,500 square steel four, transform a boring machine, gas welding tool set, pin auxiliary rough few roots, a variety of measurement tools. Boring old lathe machine availability transformation, as long as the card can be so boring bar bedside, you can move back and forth. Restructuring of the boring machine, speed to fit, easy to damage the cutter speed too fast, too slow or boring impact speed. Know more precautions, lime kiln and ears pin holes appear worn'll know how to do it!
