AI Technical Summary

Technical Problem

The manufacturing and installation of gland packings, which deteriorate over time, are cumbersome due to the difficulty in wrapping a long tape-like material around a shaft while avoiding interference with surrounding components, leading to inefficiencies in sealing performance and time consumption.

Method used

A mounting jig and device are used to facilitate the formation and attachment of gland packings by winding a tape member around a cylindrical tube attached to the shaft, utilizing a jig body with a cylindrical portion, driven portion, and pressing member to enable easy sliding and winding of the tape member onto the shaft.

Benefits of technology

The solution allows for efficient formation and attachment of gland packings on the shaft without removing surrounding components, reducing frictional resistance and time consumption, thereby enhancing sealing performance and ease of assembly.

Abstract

A mounting jig 10 is provided with a jig body 11 comprising: a cylindrical barrel part 13 which is externally fitted to a shaft A and which has a tape member 1 wound around the outer circumference thereof; a driven gear 14 which is continuous with the barrel part 13 and which rotates together with the barrel part 13 upon receiving a rotational driving force; and a pressing pin 16 which presses an end part of the tape member 1 against the outer circumferential surface of the barrel part 13. The pressing pin 16 is configured so as not to hinder slide movement of gland packings 1a, 1b formed by winding the tape member 1 around the outer circumference of the barrel part 13, in a direction away from the driven gear 14 along the axial direction of the barrel part 13. The jig body 11 is configured to be attachable to a lateral side of the shaft A.
