Embodiment Construction

[0008] As described in detail herein, exemplary embodiments of the present invention provide a face mechanical seal with an integrated pull feature configured to enable repeated installation without interfering with seal operation and remove. According to an exemplary embodiment, a face mechanical seal may include one or more removal formations attached thereto. The one or more removal formations may be a generally continuous metallic formation shaped to allow the removal formation to be grasped by a user or a standard hand tool. Accordingly, the exemplary embodiments provide a face mechanical seal that does not require special tools or equipment for routine maintenance and removal.

[0009] figure 1 A perspective cutaway view of a face mechanical seal with an integrated seal removal formation is shown in accordance with an exemplary embodiment of the present invention. As shown, the seal 100 includes a mechanical seal housing 101 . The casing 101 may have inner and outer ...

Abstract

The invention relates to an integrated end face seal removal apparatus, and specifically, a mechanical seal includes a seal cartridge and a removal formation. The seal cartridge includes an outer cylindrical surface, an inner cylindrical surface concentric to the outer cylindrical surface, and a ring surface connecting the outer cylindrical surface and the inner cylindrical surface to define an inner cavity interior to the seal cartridge. The removal formation is arranged on the ring surface, and includes a first surface proximate the ring surface, an indentation feature proximate the first surface, and a seal puller feature proximate the indentation feature defining a channel configured to allow application of removal forces to the seal cartridge.

Description

technical field [0001] The present disclosure relates to mechanical seals, and more particularly to integrated face seal removal equipment. Background technique [0002] Face mechanical seals used in engine gearbox applications need to be removed if maintenance operations have identified leaks or other problems. Such seals may be difficult to remove and in some cases may require special tools for removal. Contents of the invention [0003] According to an exemplary embodiment of the present invention, a mechanical seal includes a seal housing and a removal formation. The seal housing includes an outer cylindrical surface, an inner cylindrical surface concentric with the outer cylindrical surface, and a ring surface connecting the outer cylindrical surface and the inner cylindrical surface to define A lumen located inside the seal housing. The removal formation is disposed on the ring surface and includes a first surface proximate the ring surface, a notch feature proxim...
