The structure of the high precision bearings angular contact ball bearings and USES
[1] (Angular Contact Ball Bearings) can bear radial load and axial load at the same time. Can work under high speed. The larger the contact Angle, the higher the axial bearing capacity. High precision and high speed bearing contact Angle usually take 15 degrees. Under the effect of axial force, the contact Angle increases. Single row angular contact ball bearings can only carry axial load in one direction, when bear radial load, will cause the additional axial force. And only limit shaft or shell axial displacement in one direction. If double installed in pairs, make a pair of bearing outer ring relative, namely the wide end facing the wide end face, the narrow end face the narrow end. This can avoid the additional axial force, but also can be in two directions the shaft or shell limits in the range of the axial clearance.
Angular contact ball bearing because of its outer ring raceway can have relative displacement in the horizontal axis, so can bear radial load and axial load at the same time, joint load (single row angular contact ball bearings can only carry axial load of single direction, therefore is generally installed in pairs) is often used to.
Retainers made of brass, synthetic resins, according to the bearing form, the conditions of use and distinguish.
Angular contact ball bearings are: the type 7000 c (∝ = 15 °), type 7000 ac (∝ = 25 °) and 7000 b (∝ = 40 °) several types. This kind of lock on the outer ring of bearing, general inside and outside the circle cannot be separated, can bear radial and axial load and axial load in one direction. Carry axial load capacity is determined by contact Angle, the larger the contact Angle, is the ability to carry axial load. This kind of bearing can limit shaft or shell axial displacement in one direction.
Contact ball bearing limit rotational speed is higher, can bear radial load and axial load at the same time, also can withstand pure axial load, its axial load capacity is determined by contact Angle, and with the contact Angle increases.
Single row angular contact ball bearings can only carry axial load in one direction, when bear radial load, will cause the additional axial force, must be applied to the corresponding reverse load, therefore, this kind of bearings are generally used in pairs. Double row angular contact ball bearings can withstand the bigger radial direction load primarily radial, axial two-way joint load and torque load, it can limit shaft or shell two-way axial displacement, the contact Angle of 30 degrees.
Installation Angle contact ball bearing in pairs can afford to two-way joint mainly consisting of radial load, axial load, also can withstand pure radial load. Serial configuration can only carry axial load in single direction, the other two configurations can carry axial load in either direction. This type of bearings in general by submitting users, manufacturers matching combination pairs after installation preloading interference, ring and ball in the axial preload charge state, thus increasing the support stiffness and the whole bearing as a single rotation accuracy.
Angular contact ball bearing of main use:
Single row angular contact ball bearings, machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft
Double row angular contact ball bearing, oil pump, roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery
