Shaft seal method of manufacturing

Claim 1

The method of manufacturing a shaft seal having a radially stepped internal configuration which comprises the steps of: forming a shaft seal housing member having a ring configuration with an axially extending outer diameter wall and a radial wall intersecting with one end of the axial wall, providing a ring member having an outer diameter substantially equal to the inner diameter of the axially extending wall, the ring member having a radial wall, providing at least one circumferential groove in a surface of the said ring member, providing a brazing material in the said groove, inserting said ring member into the said housing member whereby the radial wall of the said ring member abuts a surface of the radial wall of the said housing member and the outer diameter of the said ring member abuts the inner diameter surface of the said axial wall with the said groove being in at least one of the abutting faces, subjecting the resultant assembly to heat sufficient to melt the brazing material to braze the said ring to the said housing member, at least one axial groove formed in the outer diameter of the said ring prior to insertion into the said housing, and the leg of an anti-rotation locking bar snuggly received in the said groove, the said antirotation locking bar inserted into the said groove prior to insertion of the ring into the said housing.

Claim 2

The method of manufacturing a shaft seal having a radially stepped internal configuration which comprises the steps of: forming a shaft seal housing member having a ring configuration with an axially extending outer diameter wall and a radial wall intersecting with one end of the axial wall, providing a ring member having an outer diameter substantially equal to the inner diameter of the axially extending wall, the ring member having a radial wall, providing at least one circumferential groove in a surface of the said ring member, providing a brazing material in the said groove, inserting said ring member into the said housing member whereby the radial wall of the said ring member abuts a surface of the radial wall of the said housing member and the outer diameter of the said ring member abuts the inner diameter surface of the said axial wall with the said groove being in at least one of the abutting faces, subjecting the resultant assembly to heat sufficient to melt the brazing material to braze the said ring to the said housing member, at least one axial groove formed in the outer diameter of the said ring prior to insertion into the said housing, and the leg of an anti-rotation locking bar snuggly received in the said groove, the said antirotation locking bar inserted into the said groove prior to insertion of the ring into the said housing.

Claim 3

The method of manufacturing a shaft seal having a radially stepped internal configuration which comprises the steps of: forming a shaft seal housing member having a ring configuration with an axially extending outer diameter wall and a radial wall intersecting with one end of the axial wall, providing a ring member having an outer diameter substantially equal to the inner diameter of the axially extending wall, the ring member having a radial wall, providing at least one circumferential groove in a surface of the said ring member, providing a brazing material in the said groove, inserting said ring member into the said housing member whereby the radial wall of the said ring member abuts a surface of the radial wall of the said housing member and the outer diameter of the said ring member abuts the inner diameter surface of the said axial wall with the said groove being in at least one of the abutting faces, subjecting the resultant assembly to heat sufficient to melt the brazing material to braze the said ring to the said housing member at least one axial grooVe formed in the outer diameter of the ring prior to insertion into the housing, the base leg of a T-shaped bar snuggly received in the groove with the cross head of the T bar axially spaced from the said ring, the said T bar inserted into the groove prior to insertion of the ring into the housing, the circumferential groove positioned such that the melting of the brazing material therein will braze the T bar to the ring and to the housing.

Claim 4

The method of manufacturing a shaft seal having a radially stepped internal configuration which comprises the steps of: forming a shaft seal housing member having a ring configuration with an axially extending outer diameter wall and a radial wall intersecting with one end of the axial wall, providing a ring member having an outer diameter substantially equal to the inner diameter of the axially extending wall, the ring member having a radial wall, providing at least one circumferential groove in a surface of the said ring member, providing a brazing material in the said groove, inserting said ring member into the said housing member whereby the radial wall of the said ring member abuts a surface of the radial wall of the said housing member and the outer diameter of the said ring member abuts the inner diameter surface of the said axial wall with the said groove being in at least one of the abutting faces, subjecting the resultant assembly to heat sufficient to melt the brazing material to braze the said ring to the said housing member at least one axial grooVe formed in the outer diameter of the ring prior to insertion into the housing, the base leg of a T-shaped bar snuggly received in the groove with the cross head of the T bar axially spaced from the said ring, the said T bar inserted into the groove prior to insertion of the ring into the housing, the circumferential groove positioned such that the melting of the brazing material therein will braze the T bar to the ring and to the housing.
