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.

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.

FAG 7309-B-TVP Angular contact ball bearing

Angular contact ball bearings (Angular Contact Ball Bearings) is a bearing that can support radial and axial loads. Able to work at higher speeds. The contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase.


Angular contact ball bearings: 7000C-type ( = 15 ), 7000AC type ( = 25 ) and 7000B ( = 40 ) of several types. This kind of bearing outer ring locking in general inside and outside the ring can not be separated, can be combined radial and axial load and axial load in one direction. Axial load capacity by the contact angle, the contact angle is larger, the ability to withstand high axial loads. This kind of bearing can limit the axial displacement in one direction or housing.


The higher speed limit contact ball bearings can support radial load and axial load can also be subject to pure axial load, axial load capacity by the contact angle, and increases with the contact angle increases.


Application:
Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifuges, small car front wheel, the differential pinion shaft, booster pumps, drilling platforms, food machinery, dividing head, fill welder, low-noise cooling tower, electrical equipment, painting equipment, machine slot board, welding machines


Double row angular contact ball bearings: pump, blower, air compressor, various types of transmission, fuel injection pump, printing machinery, planetary reducer, extraction equipment, cycloid reducer, food packaging machinery, welding, soldering iron, square box, gravity gun, wire strippers, axle, test analysis equipment, chemical machinery
