Problems solved by technology
The invention discloses a shaft seal installation tool and a shaft seal installation method. The shaft seal installation tool is characterized in that an installation ring comprises a radial supporting surface, an axial supporting surface and an inner hole conical surface; the outer diameter of the axial supporting surface is greater than the minimum inner diameter of the inner hole conical surface, and the width of the axial supporting surface is greater than the cross section diameter of a seal ring; and the minimum inner diameter of the inner hole conical surface is matched with a predetermined seal size of the seal ring and slightly greater than the outer diameter of a shaft required to be installed with the seal ring. The installation ring further can form a combined installation tool together with a guide ring. During installation, the seal ring is used for sleeving the axial supporting surface of the installation ring directly or through the guide ring, the installation ring is moved to the left side of a seal groove in the shaft, the seal ring is pushed in the seal groove, the installation ring is taken out reversely, and the inner hole conical surface is extruded for enabling the expanded and deformed seal ring to be recovered in size; and by repeating the steps, a plurality of seal rings can be installed. By applying the shaft seal installation tool and installation method, the seal rings can be conveniently installed and the cutting damage of the seal rings during subsequent parts assembly can be prevented.
