[Retracted] Performance Analysis of High-Speed Deep/Shallow Recessed Hybrid Bearing

Table 1

The parameters of high-speed deep/shallow recessed hybrid bearing.

Bearing diameter (mm)	Bearing length (mm)	Orifice diameter (mm)
𝐷=60	𝐿=60	𝑑𝑐=1
Rotor speed (rpm)	Depth of deep recess (mm)	Inlet temperature (°)
𝜔=30000	ℎ𝑝=0.5	𝑇0=20
Half angle of recess (°)	Depth of shallow recess (mm)	Width ratio of shallow recess
𝜃=0--30	ℎ𝑟=0.01--0.05	𝑘=0.25--4
Radial clearance (𝜇m)	Viscosity (pa·s)	Supply pressure (Mpa)
𝑐=20	𝜇0=0.001	𝑃𝑠=3

𝑘 is the width ratio, 𝑘=𝜃_𝑑∶𝜃_𝑠,𝜃_𝑑: half angle of deep recess, and 𝜃_𝑠: half angle of shallow recess.
When 𝑘=0 or 𝑘=∞, the deep/shallow recess is changed to shallow or deep recess.
