D bearing outer diameter; according to the bearing load; usually ensure that the uniform pressure on the tile pm = 1. 5 ~ 3. 5MPa is appropriate; there are bearings for the load-bearing equipment; pm = up to 6 ~ 7MPa.
d Bearing inner diameter; the outer diameter of the bearing is determined by the ratio D/d; usually D/d=1. 2~2. 5 is suitable. D/d determines the bearing width B.
B bearing width; B = (Dd) / 2. Usually take the width to length ratio B / L = 1 or so; bi-directional transformation B / L = 0.6.
z Axis wattage; affects bearing length L; usually takes z=6~12; not less than 3; up to 20 or more. Excessive wattage will reduce bearing capacity; but can lower oil temperature.
α wattage angle; α = 360k / z; k = (0. 7 ~ 0. 85) is the fill factor.
L-axis length; L=kπ(D+d)/2z; inter-tile width Lk=(1-k)π(D+d)/2z.
β axis is the height of the skew; the difference between the maximum gap h1 and the minimum gap h2 of the bearing bush and the journal; β=h1-h2.
H1 and h2 are the maximum and minimum oil film thickness of the bearing respectively. h2=hmin The minimum oil film thickness; it is determined according to the criterion of ensuring complete fluid smoothness; the external roughness Ra is large; the hmin≈2Ra=0.01~0 is usually taken. 05mm. Bearings with poor precision in the production of the device should be properly increased.
β/h2 wattage ratio; is the primary technical parameter for bearing depiction; can be optimized by clicking the “Accounting different wattage specific static characteristics†button; optimal β/L ≈1. 2; usually taking 1.2 to 2. 0 better
