One of the bearings of the cold rolling mill must be checked

The cold rolling mill bearing is a component that fixes and reduces the load friction coefficient during the mechanical transmission process. The quality of the bearing directly affects the working condition of the cold rolling mill, so the overhaul of the bearing of the cold rolling mill is also very important. According to the knowledge of Gongyi Jindi Metallurgical Equipment Co., Ltd., there are three types of bearing repair methods for cold-rolling mills, namely, three types, namely, maintenance during operation, inspection after disassembly, and troubleshooting.
1. Maintenance during operation: When the rolling bearing lacks oil, it will hear the sound of “bone and bones”, and if it hears the sound of discontinuous “stemmed stems,” it may be the rupture of the bearing steel ring. When the bearing is mixed with sand and other debris or bearing parts have mild wear, it will produce a slight noise.
2, after the demolition of maintenance: first look at the bearing rolling elements, inside and outside the steel ring whether there is damage, corrosion, scars, etc., and then hold the bearing inner ring by hand, and make the bearing flat, the other hand push hard outside the ring, if The bearing is good, the outer rims should turn smoothly, there is no vibration and obvious seizure in the rotation, and the outer rims do not have a retrograde phenomenon after stopping. Otherwise, the bearing can no longer be used. Hold the outer ring with your left hand and pinch the inner rim with your right hand. Use force to move in all directions. If you feel loose when you push it, it will wear out.
3. Troubleshooting: The rust on the outer surface of the bearing can be wiped off with No. 00 sandpaper and then cleaned in gasoline. If the bearing has cracks, internal and external cracks, or excessive bearing wear, replace the new bearing. When replacing a new bearing, use the same bearing as the original model.
Cold rolling mill bearing repair method is the above three. The equipments produced by Gongyi Jindi Metallurgical Equipment Co., Ltd. include: cold rolling mills, cold rolling equipment, two-rib cold rolling mills, cold-rolled ribbed steel rebar equipment, cold-rolled ribbed steel rebar production lines, hot-rolling wire take-up machines, and steel reinforcement Straight cutting machine, steel straightening machine, steel cutting machine, fly shearing machine, steel extension machine, high-frequency quenching equipment, three-level steel straightening cutting machine, I-wheel take-up machine, steel reversing material rack.
