Can full cylindrical roller bearings bear axial loads?

Can full cylindrical roller bearings bear axial loads?

Can full cylindrical roller bearings bear axial loads? SKF's fully loaded cylindrical roller bearings are designed to sustain heavy loads. Under the same width, compared with cage bearings, this bearing can contain the most rollers, with a very high bearing talent; However, the allowable speed is much lower than the cylindrical roller bearing with holding. Fully loaded double row cylindrical roller bearings are available in 4 layout types, 3 open layout and 1 with sealed layout. All products are short and long separation plan, outer ring with lubricating groove and lubricating oil hole, convenient lubrication.

Tapered roller bearings are widely used in the automotive industry

Tapered roller bearings are widely used in the automotive industry

Tapered roller bearing is a widely used mechanical support. Its function is to support the shaft and the parts on the shaft under the condition of ensuring the bearing has enough life, and make relative rotation, swing and other movements with the frame, so that the friction between the rotating pair is reduced as far as possible, in order to obtain higher transmission efficiency. Tapered roller bearings mainly bear combined radial and axial loads. Bearing capacity depends on the raceway Angle of the outer ring, and the greater the Angle, the greater the bearing capacity. Tapered roller bearings have tapered inner and outer raceways with tapered rollers arranged in between. The projection lines on all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact Angle α. The larger the α Angle, the higher the axial load capacity. The Angle is represented by the calculated coefficient E. The larger the e value and the greater the contact Angle, the greater the applicability of bearing under axial load. Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries. Since the founding of new China, China's tapered roller bearing industry has achieved rapid development. However, at present, from the point of view of product development, product quality level and production and manufacturing level, there is a large gap with the world tapered roller bearing manufacturers, most of them are at the imitation level, and generally low-grade tapered roller bearings account for the majority. Therefore, in recent years, China has been increasing efforts in scientific research, and has made certain progress in the level of products. At present, the development trend of China's tapered roller bearing industry is as follows: increase production scale, improve production investment; Strengthen scientific research and innovation, especially focusing on bearing life and reliability; Continuously adjust a wide range of product mix, deepen the taper roller bearing structure design and application technology research, expand the special high-precision and high-value-added taper roller bearing capacity; Focus on the development of speed, accuracy, high reliability, long life, low friction, low vibration, low noise, high-tech bearing products.

The production and processing of roller bearings see many problems

The production and processing of roller bearings see many problems

The production and processing of roller bearings see many problems In the past, in addition to the small end of the roller bearing fillet corner area and one side of the column center are subjected to three-way compressive stress, the vast majority of general cases are subjected to consistent compressive stress and two-way tensile stress, the closer the roller bearing big end of the tensile stress is greater, the tensile stress will cause intergranular deformation of metal material, so that the metal material plastic deformation is low. Therefore, when the wool embryo or abrasive specifications plan is not scientific, the raw material is poor, the processing technology is not good, roller bearings usually cause cracks in the big end fillet corner. In addition, the friction between the roller bearing and the grinding tool, the asymmetry of the internal mechanism of the raw material and the specification of the grinding tool are not scientific, but also cause extra ground stress inside the roller bearing, reduce the plastic deformation of the metal material, improve the deformation resistance of the metal material, and cause internal stress inside the roller bearing.

A brief description of the use characteristics of seven kinds of bearing rollers

A brief description of the use characteristics of seven kinds of bearing rollers

1. Seven types of bearing rollers have excellent rotation accuracy The internal structure of seven types of bearing rollers adopts 90° vertical cross arrangement between rollers, and there is a spacer or isolation block between rollers, which can prevent the friction between the inclined goods rollers and effectively prevent the increase of rotating torque. In addition, there will be no roller contact phenomenon or lock phenomenon; At the same time, because the inner and outer rings are divided structure, the clearance can be adjusted, even if the preload is applied, also can obtain high precision rotary motion. 2. Simplify operation and installation The outer or inner ring, which is divided into two parts, is fixed together after loading seven types of bearing rollers and retainers, so installation is very simple to operate. 3, bear large axial and radial load Because the rollers are arranged perpendicular to each other on the 90° V-groove rolling surface by spacer, this design enables the seven types of bearing rollers to withstand large radial, axial and torque loads in all directions. 4, greatly save installation space The inner and outer ring sizes of seven types of bearing rollers are minimized, especially the ultra-thin structure is close to the limit of small size, and has high rigidity. Therefore, *** is suitable for industrial robot joints or rotating parts, machining center of the rotary table, manipulator rotating part, precision rotary table, medical instruments, measuring instruments, IC manufacturing devices and a wide range of uses. 5. High speed capacity 6. Reduce shaft length and machining cost, thermal expansion leads to limited changes in geometric dimensions 7. Nylon separator, low moment of inertia, low starting torque, easy to control Angle division 8. Optimized preload, large stiffness, high precision of guide roller operation 9. Carburized carbon steel provides excellent impact resistance and surface wear resistance 10. Simple but well lubricated
