The product characteristic thrust spherical roller bearing is the same as the spherical roller bearing; the raceway surface is a spherical surface with a common point on the intermediate shaft of the bearing; the bearing roller is spherical; thus; Heart function; not very sensitive to concentricity and shaft deflection.
It is different from other thrust bearings in the sample; the axial load of such bearings can be very large; several radial loads can be accepted together with the axial load; but the radial load must not exceed 55% of the axial load.
Only the load P and P0 do not exceed 0. 05C0; and the shaft rotates; the bearing agrees with the centering angle listed in the table below.
Bearing Diameter Series Self-aligning Angle Bearing Diameter Series Self-aligning Angle 200 Series 1°~1. 5° 300 Series 1. 5°~2° 400 Series 2°~3° Small values ​​for larger bearings; and increased load The angle of the center of the promised time will be reduced.
When used, oil is usually used. This type of bearing is mainly used in hydroelectric generators; vertical motors; propeller shafts for ships; tower cranes; extruders, etc.
● Product classification symmetric thrust spherical roller bearing asymmetric thrust spherical roller bearing ■ The basic scale of the scale scale ZWZ thrust spherical roller bearing has been listed in the scale table;
Inner diameter scale: 60mm ~ 1120mm
Outer diameter scale: 130mm ~ 1460mm
Height scale: 39mm ~ 354 mm
â—† Public service ZWZ can provide P0, P6, P5 level public service products.
★ Brass cages and stamping frames are usually used for cage cages. When brass solid cages are used, the rear brackets are not marked; other markings are corresponding to the rear code.
● Minimum axial load required for minimum axial load thrust spherical roller bearings;
Famin (take the larger value obtained by the following two formulas)
Famin=C0a/2000
Famin=1.8Fr+1.33(C0a/2000)2×
In the formula:
Famin: minimum required axial load kN
n: Speed ​​C0a: fundamental extra static load kN
Fr : radial load kN
â–  Equivalent dynamic load P=Fa+1. 2Fr
★ Equivalent static load P0=Fa+2.7Fr
This type of bearing is mainly used in oil drilling rigs; steelmaking machinery.
