Two Structures Of Self-Aligning Ball Bearings

wallpapers News 2020-04-01

Self-aligning ball bearings usually cannot accept the pure axial load. It is uniquely suitable for bearings that can cause considerable shaft deflection or misalignment, such as beautiful appearance, low-noise motors, automobiles, motorcycles, woodworking machinery, textiles Mechanical transmission shafts, mining machinery, electromechanical equipment, plastic machinery, work equipment, medical equipment, fitness and sports equipment and general machinery, etc .They are the most widely used type of bearings in the machinery industry.

1. Cylindrical hole

With its two rows of steel balls and curved raceways in the outer ring, self-aligning ball bearings can be self-aligning. It can accept the viewpoint error between the shaft and the bearing seat, which is suitable for the working conditions that show the shaft deflection and misalignment caused by the misalignment. Friction is the lowest of all rolling bearings, even at high speeds; still with only a small temperature rise

2. Tapered hole

Tapered hole self-aligning ball bearings have the characteristics of cylindrical hole self-aligning ball bearings (but the inner hole is a tapered hole (standard taper 1:12). The device can be used to adjust the bearing clearance on a tapered shaft finely. This type of bearing is mostly used under load. Under the effect of the large tortuous double support shaft, and the two support seat holes can not ensure severe concentric parts. It is mainly used to receive radial loads, and it can also accept a small number of axial loads. Usually, it cannot take pure axial loads. The universality of this type of bearing is second only to deep groove ball bearings. Its limit speed is lower than that of deep groove ball bearings with the same specifications, but its bearing capacity can be higher than deep groove ball bearings.

In addition, in the process of cleaning and maintaining the bearings, we must guard against debris wedging between the rolling elements, which is the most deadly for the bearings, especially the application of small bearings that needs to pay attention to this problem.
