1 Screw roller bearing is introduced

  Screw roller bearing rolling system using steel belt winding of screw roller. Therefore, called screw roller bearing. This kind of bearing has great flexibility and radial clearance, can withstand the tremendous impact of the radial load, cannot bear axial load, limit rotational speed is low. Only applies to rotary accuracy is not high, and often have larger impact load in parts. Bearing installation allows inner ring and outer axis axis is 0.5 ° slope. Because of this kind of bearing elastic deformation, in the work can guarantee accuracy, so the accuracy of screw roller bearing is a kind of common, and there is no other precision level.

2 Screw roller bearing characteristics

    Bearing inner ring and outer screw by alloy steel belt, with a special processing technology assembly and become. Bearing internal and external ring surface spiral aperture, can make oil continuous evenly throughout bearing work surface. Bearing in the operation condition of the large temperature difference under the working conditions, bearing fit size can be automatically compensation.

3 Screw roller bearing process

     Bearing inner ring and outer screw by alloy steel belt, with a special processing technology assembly and become. Bearing internal and external ring surface spiral aperture, can make oil continuous evenly throughout bearing work surface. Bearing in the operation condition of the large temperature difference under the working conditions, bearing fit size can be automatically compensation. Mainly engaged in P&N about plank guide roll used bearing design and production, arc casting machinery each part of the need of the bearing design. P&N can provide all these different bearing design.  

4  Screw roller bearing advantages

     A) this kind of bearing is made by the spring steel. Spring steel annealing temperature is 3500 c. Therefore, it is larger than annealing temperature for 1800 c ball bearing steel (100 c6) temperature sensitivity difference. Materials in the temperature reaches tempering temperature above will be extremely lost its hardness. So the spring steel is more suitable for high temperature operation

      B) spring steel have good flexibility, so easy to install, inner ring can pass with the help of two hook spanner installed in any position, the inner ring of the internal tension can make its binding on the shaft. Use elastic material processing tolerance for h9 or h1l the inner circle is more easy to achieve

       C) the bearing durable and by dirt, scrap iron, water and the falling iron powder and water formation of weak acid of the impact is not big. Thin wall spiral coil for large diameter rolling parts left a larger space. These components can pass rolling will booty and foreign matter pressure to the spiral coil in the gap. This can keep the bearing surface movement in turns kept clean.

        D) spiral bearing main advantage is the outer race can be reused many times, this makes once when, due to the influence of the temperature and produce damage and bending to carry on the reworked become possible. In this case, the bearing also need to adjust. This kind of structure design only outer spiral instead of a complete set of bearing should be change, all the rest of the bearing parts can be used again. Bearing adjustment is through the diameter size to 1 mm amplitude increasing ways to the. For example: when the diameter increased from 105 mm to 106 mm, outer spiral diameter also need to increase LMM for installation. This kind of situation can repeat to 110 mm diameter when. This bearing ring can be repeated processing five times. It can save cost a lot, especially in all the other bearing parts can be repeated use under the condition of 6 times.
