Abstract
A porous ultrasonic bearing includes a ring, a high-strength outer casing, a bearing bushing and a vibration collar. The high-strength outer casing is sheathed on the bearing bushing, and a group of radial holes that penetrate are provided on the bearing bushing. The vibration collar is arranged between the high-strength outer casing and the bearing bushing. The outer cylindrical surface of the vibration collar is fixedly connected to the inner hole of the high-strength outer casing. A gap is provided between the inner hole of the vibration collar and the outer cylindrical surface of the bearing bushing. The vibration collar radially vibrates at high frequency. A high-strength lubricating oil film is formed between the inner hole of the bearing bushing and the shaft, so that the friction between the inner hole of the bearing bushing and the shaft is reduced.
