For trunnion free retaining ring in general, reasonable installation is very important, so what are the requirements for the installation of the ear ring?
The fixation of parts on the shaft is pided into axial fixation and circumferential fixation. The trunnion ring used for the shaft mainly plays the role of tightening the axial direction, in which the conical surface plus the trunnion ring has a high degree of centering. The ear less retaining ring is also used in the working conditions of dynamic seal and static seal. The dynamic seal can be used at the outer seal and the inner seal.
Installation of trunnion free retaining ring for shaft: if the pressure only acts on one side of O-ring and star seal ring, only one trunnion free retaining ring needs to be placed on the pressure side. If the compression direction is changed, you need to use an additional trunnion ring for the shaft, and place a trunnion ring for the shaft on both sides of the sealing ring. However, in order to avoid errors during assembly, it is recommended to install two trunnion free retaining rings for shafts even if the pressure only acts on one side.
Therefore, these details should be done well when installing the ear less retaining ring to ensure its good performance.
