Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. It can also be said that when other components generate relative motion on the shaft, it is used to reduce the friction coefficient during power transmission and maintain a fixed position of the shaft center. Bearings are a crucial component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the different frictional properties of moving components, bearings can be divided into two types: rolling bearings and sliding bearings. 1、 There is a contact angle between the angular contact ball bearing ring and the ball. The standard contact angles are 15 °, 30 °, and 40 °. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive it is to high-speed rotation. Single row bearings can withstand radial and unidirectional axial loads. Structurally, two single row angular contact ball bearings with a back combination share the inner and outer rings, which can withstand radial and bidirectional axial loads. Main uses of angular contact ball bearings: single row: machine tool spindle, high-frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft. Dual column: oil pump, Roots blower, air compressor, various transmissions, fuel injection pump, printing machinery. 2、 The self-aligning ball bearing has two rows of steel balls, and the outer race is of the inner ball surface type. Therefore, it can automatically adjust the misalignment of the shaft caused by the bending or non concentricity of the shaft or shell. The tapered hole bearing can be easily installed on the shaft by using fasteners, mainly bearing radial loads. The main use of self-aligning ball bearings: woodworking machinery, textile machinery transmission shafts, vertical seat self-aligning bearings. 3、 Self aligning roller bearing This type of bearing is equipped with spherical rollers between the outer ring of the spherical raceway and the inner ring of the double raceway. According to different internal structures, it can be divided into four types: R, RH, RHA, and SR. Due to the consistency between the arc center of the outer raceway and the center of the bearing, it has self aligning performance. Therefore, it can automatically adjust the axis misalignment caused by the deflection or non concentricity of the shaft or shell, and can withstand radial misalignment
