Four row circular cone roller bearings basic installation requirements

Is the basic requirement of installation: installation specially trained personnel, check the bearing fits the shape tolerance, maintain the cleanness of installation place, installation to complete before you open the bearing packing, don't wash away anti-rust oil bearing. （ 1) Configuration of the bearing components. Open the bearing packing, do not wash out the rust-proof, check the bearing components, to ensure the complete bearing components, production date, serial number, production installation sequence with letters. Bearing fitting surface using Ⅰ Ⅳ 90 ° apart with four bearing area, etched on axial line of the outer ring outside diameter on bearing area. （ 2) With the bearing surface. In order to prevent the roll neck and cooperate with the friction bearing corrosion, must be installed to the coated with a thin layer of cream, bolts will roll the end cover is fixed on the bearing seat, the bearing seat open up placed in the plane of support. （ 3) Open type bearing. First of all, E end down, will outer D - E and outer baffle D filed into the bearing seat, and then lift parts in a given order after in the bearing seat. Note alignment bearing area, after the installation of the parts must be in contact with the front parts completely, there can be tilted or skewed. （ 4) Have stamping cage open the installation of the bearing. Have a stamping cage bearing inner ring to E - Ce flat on the support ( E end down) And then one by one in correct order placed components, use lifting device will be complete within the bearing load bearing component, to ensure correct bearing area Ⅰ alignment. Wear the pin type cage bearing, E - the inner circle Ce（ E end down) , inner baffle C ( Positioning guard down) , double row outer ring - B D and separated from B in bearing cage bearing wear pin type, the inner ring - A Ca and single outer ring - A B load bearing, bearing area Ⅰ ensure correct alignment, wear the pin type cage bearing can use like with stamping cage bearing lifting device for installation. （ 5) The installation of sealed bearing. With the aid of a kind of special lifting device to install sealed taper roller bearings. In a given order, fully assembled bearing components in the ascending device. First installation of sealing ring E, when installing a grease lubricated bearing, roller and cage should be artificial lubrication. Ensure proper alignment Ⅰ bearing area, will have assembled a complete bearing load bearing. （ 6) Rotary bearing. On the circular symmetric position gently with four bolts will be the second end cover installation ( Do not tighten bolts) On the bearing seat, bearing seat rotate to horizontal position, with the pull rod to fix the fixture, circle face, at the beginning to lighter, fixture can only contact with inner ring end face. For the sealed bearing, lifting device used as a fixture at the same time. Gradually tighten rod and the end cover bolts and slow evenly rotating inner ring, until the inner ring to fully cooperate with every circle in C without a break. Using a feeler cover and bearing clearance between S, determine the thickness of the sealing B. Rigid seal = S - B ( 0. 05 ~ 0. 1) mm； Elastic sealing B = 1. 2Smm。 （ 7) Install the seal. Unscrew the end cover bolts and removing the end cover, insert the required thickness of the sealing end cover, inside hole covered with grease complete the installation. （ 8) In the oil bath heating labyrinth seal ring, push the labyrinth sealing ring together with the o-ring loaded on the roll neck, in the labyrinth seal ring cooling process, must tightly to the pressure on the roll end face. （ 9) Push the assembly good bearing loaded on the roll neck, regularly check the effectiveness of the bearing seal and bearing temperature, bearing 1000 ~ 1200 h after work, change the bearing load bearing area. Bearing all maintenance and inspection work, records on rolling bearing test card. Change bearing load bearing area, in the order in contrast to the installation removal of bearing, carefully clean the bearing parts, then immediately apply oil, visual raceway and roller damage, check the axial clearance, use the new grease packaging bearing, according to the installation instructions to install bearing, bearing area and go to the next. Change the bearing zone for the first time, the outer ring rotate 180 ° to the bearing area Ⅲ; The second rotate 90 ° to bearing area IV; The third time rotate 180 ° to Ⅱ. For tapered roller bearing with seal, working in the bearing respectively after 300 h, 600 h and 900 h, follow these steps to add check: remove the bearing seat and remove end cover, check in the amount of oil in the bearing and the labyrinth seal and grease. If the oil pollution of fading or, to fill the new oil bearing and labyrinth seal. Carefully check the bearing seal, even a slight damage to replace seal, all maintenance and inspection work of bearing, record to the rolling bearing test card.
