AI Technical Summary

Technical Problem

During the press-fitting of a ship's stern shaft bearing, the stern bearing may rotate, causing it to shift vertically and resulting in press-fitting failure.

Method used

Design a press-fit guide device including a guide body, rolling bearings and a guide mandrel. The guide mandrel provides circumferential constraint through the cooperation with the longitudinal oil groove of the stern bearing. Combined with the stepped fit design, it ensures the alignment of the stern bearing and the bearing housing. A detachable cross pressure plate is used to transmit pressure.

Benefits of technology

This ensures that the stern bearing does not shift during the press-fitting process, guarantees smooth bearing movement, avoids press-fitting failure, and improves the success rate of press-fitting.
