What are the advantages of self-aligning bearings?
A self-aligning ball bearing is a roller with a drum shaped roller between the inner ring of the two raceway and the outer ring of the spherical surface. The center of curvature of the outer raceway is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing.Advantage(1) when the shaft and shell appear bending, it can be adjusted automatically without increasing the bearing load.(2) the radial load of self-aligning ball bearing is large, and it is suitable for heavy load and impact load.(3) good vibration resistance.(4) compensating for concentricity errors due to machining, installation, and shaft deformation.
How many kinds of self-aligning bearings are there?:Self-aligning ball bearingSpherical Roller BearingsSelf-aligning needle roller bearingAnd drum roller bearings (SKF's CARB Series)These bearings have aligning function, the so-called heart, is mainly in the shaft misalignment, bearing roller and spherical rolling automatic adjustment by road between, still maintain the normal operation of the realization of the right under certain function, so the Japanese manufacturers also called self-aligning ball bearing self-aligning bearing.The self-aligning ball bearing self-aligning (automatic centering) function is applied to the vibration condition because of its adaptability, automatic aligning function, and when the mechanical shaft vibration, between roller and raceway can automatically adapt to the change of the angle, so as to reduce the damage of the shaft and bearing. At the same time, in the installation, the requirements for centering are also lower, and the absolute centering is not required (that is, the radial cross section of the bearing is close to the absolute 90 degrees of right angle), so that it can be conveniently installed.Self-aligning bearing is mainly used for vibration, such as vibration motor, vibration sieve, spherical roller bearings are widely used in large machinery engineering machinery, mining machinery and so on, can not be replaced.In the final analysis, the biggest advantage of self-aligning bearing is its automatic self-aligning function, it can well adapt to the wrong working conditions.
Self-aligning bearings for equipment installation, alignment requirements, non - self-aligning bearings require high.Self-aligning bearing is like a universal coupling, in the course of work, according to the axial axis, radial accumulation, to give certain compensation.
