What are the main features of spherical roller bearings?

The spherical roller bearing is a double row non separable bearing. Its structure includes solid outer ring with spherical raceway, solid inner ring and drum roller with cage. The inner ring has cylindrical hole or conical hole. The symmetrical drum roller can be adjusted freely in the outer ring spherical raceway. Therefore, the bending of the shaft and the misalignment of the mating surface can be compensated.

What is a spherical roller bearing?

Spherical roller bearing is a kind of radial bearing, which can bear radial load and can also bear two-way bearing load. Spherical roller bearings have a large radial bearing capacity and a self-aligning function. They have low requirements on the machining accuracy of the casing, avoid installation errors or shaft deflection and affect the use of the bearing, and have high vibration and shock resistance.

What are the main features of spherical roller bearings?

(1) Similar to the self-aligning ball bearing, the outer ring raceway of the self-aligning roller bearing is a part of the spherical surface, and its center of curvature is on the bearing axis. The outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good. It can compensate the coaxially error, so it can realize automatic centering.

(2) In the section perpendicular to the rolling direction, the busbar of the roller is a curve, which can be well matched with the inner and outer raceways. The rollers and the raceway are in line contact, and can withstand radial and axial loads. impact resistance.

(3) The rollers of the spherical roller bearing have a high degree of conformity with the raceway, and they are all curved generatrixes, so the relative sliding is serious, and the friction is larger than that of the cylindrical roller bearing, so the allowable working speed of the spherical roller bearing is lower.

How to use light bulb heating method to heat spherical roller bearings?

Using a 50W light bulb to heat the spherical roller bearing can ensure that the heating temperature is around 100°C. The smaller bearing can be placed directly on the bulb, and the larger bearing can be placed in the conical cover of the light bulb, which can prevent the heat of the light bulb. Dissipate, make the heating uniform, the cone cover can be adjusted up and down, and can adapt to heating bearings of different sizes within a certain range. If far-infrared light bulbs are used, pay attention to the direction of the light bulbs, so as to avoid infrared rays that are harmful to human eyes. This kind of light bulb adopt the energy-saving bulb heating method which is suitable for a small number and not often required; where the bearing needs to be heated, the bulb can also be used for lighting at ordinary times, and no other equipment is required.
