Split bearing assemblies, air-cooled heat exchangers and related methods

摘要

Bearing assemblies are provided that include a bearing having a split bearing body that includes a material such as a composite or a thermoplastic; and at least one recess configured for receiving a rotary seal assembly; and at least one rotary seal assembly comprising an energizing component. The bearing assemblies may further include at least two recesses and/or an energizing component that is an o-ring.

主权项

1. A bearing assembly comprising a bearing and at least one rotary seal assembly comprising an energizing component,
wherein the bearing has: a split bearing body split along an axial direction that comprises material chosen from a composite or a thermoplastic, and at least one recess configured for receiving the at least one rotary seal assembly, and wherein the at least one rotary seal assembly is a split spring-energized seal assembly that comprises:
a seal assembly body having a first seal assembly body portion and a second seal assembly body portion, the first seal assembly body portion and the second seal assembly body portion each having a generally semi-circular cross-sectional configuration when viewed in an axial direction of the bearing assembly so that when the first and the second seal assembly body portions are joined to form the seal assembly body, they also form a generally circular cross-sectional configuration in the axial direction of the bearing assembly and wherein the seal assembly body portions are shaped to define a groove within each of the first and the second seal assembly body portions, wherein the grooves in the first and the second seal assembly body portions together are configured to meet in generally facing engagement;
a spring element configured to be received within the grooves, the spring element having an opening configured to receive the energizing component, wherein the energizing component that is sized to fit within the opening in the spring element within the grooves in the first and the second seal assembly body portions to form a ball-and-socket o-ring configuration within the split metal spring-energized seal assembly and the energizing component comprises an elastomeric material.
