Typical Range

Results are provided for an investigation of a compliant-surface, tilting-shoe bearing, when operating in oil. Two values of elastomer durometer were used on shoes as well as seven different pivot locations. The investigation included measurements of lubricant film pressure fields and film-thickness profiles under the shoes during operation. Friction and overall stiffness were also recorded for a typical range of speeds, loads, and pivot positions.

Theoretical Results

The paper presents experimental and theoretical data on the axisymmetric hydrostatic thrust bearing with one bonded compliant surface. The theoretical results are exact and are based on linear elasticity theory. The effects of compliance on the behavior of the thrust bearing are discussed and illustrated.

Theoretical Results

This paper studied the air film pressure field (AFPF) characteristics of aerostatic thrust bearing, in which we proposed the measurement equipment for the 2D AFPF and successfully verified the theoretical simulation results. The experimental results agreed well with the theoretical results. However, in the area between the distribution circle of orifice to the air film outlet boundary, the experimental air film pressure (AFP) was slightly higher than the theoretical one. While for the area between the distribution circle of orifice and the center of the bearing, it showed the opposite law. Besides, the increase ratio of the AFP was close to that of the external load with its increase.
