Abstract

An installation tool for installing a seal includes a shaft and a seal-engaging component coupled with the shaft. During an installation of the seal, the seal-engaging component is adapted to couple with the seal. The seal-engaging component includes a first surface and a second surface. The seal-engaging component also includes a first annular ring extending from the first surface and adapted to engage with the seal for coupling the seal with the seal-engaging component. The seal-engaging component further includes a second annular ring extending from the first surface. The installation tool also includes a sliding hammer adapted to slide along a length of the shaft. During the installation of the seal, the sliding hammer is adapted to apply a force to the seal-engaging component for installing the seal at a seal installation location.

First claim

The invention claimed is:

1. An installation tool for installing a seal, the installation tool comprising:
a shaft defining a first end, a second end opposite to the first end, and a length defined between the first and second ends;
a seal-engaging component coupled with the shaft proximal to the first end of the shaft, wherein, during an installation of the seal, the seal-engaging component is adapted to couple with the seal such that the seal is coaxial with the seal-engaging component, the seal-engaging component including:
a first surface disposed proximal to the first end of the shaft;
a second surface disposed distal to the first end of the shaft and opposite to the first surface, wherein the seal-engaging component defines a cavity partially extending from the second surface toward the first surface;
a first annular ring extending axially from the first surface, wherein the first annular ring is adapted to engage with the seal for coupling the seal with the seal-engaging component; and
a second annular ring extending axially from the first surface and concentric with the first annular ring, such that, during the installation of the seal, a portion of the seal is radially disposed between the first annular ring and the second annular ring;

a sliding hammer mounted on the shaft and adapted to slide along the length of the shaft, wherein, during the installation of the seal, the sliding hammer is adapted to apply a force to the seal-engaging component based on a sliding of the sliding hammer towards the first end of the shaft for installing the seal at a seal installation location; and
an impact plate adapted to be received within the cavity of the seal-engaging component, wherein the impact plate is adapted to contact the sliding hammer for applying the force to the seal-engaging component.

2. The installation tool of claim 1 , wherein each of the seal-engaging component and the impact plate is threadedly coupled with the shaft.

3. The installation tool of claim 1 further comprising a handle threadedly coupled with the shaft proximal to the second end of the shaft.

4. The installation tool of claim 1 , wherein,
the first annular ring defines a first diameter; and
the second annular ring defines a second diameter, the first diameter being greater than the second diameter.

5. The installation tool of claim 1 , wherein the first annular ring is received within a groove defined by the seal for coupling the seal-engaging component with the seal.

6. The installation tool of claim 1 , wherein the seal-engaging component includes:
a first portion disposed proximal to the first end of the shaft and defining the first surface; and
a second portion integral with the first portion, the second portion being disposed distal to the first end of the shaft and defining the second surface, wherein an exterior part of the second portion tapers from the first end of the shaft towards the second end of the shaft.

7. The installation tool of claim 1 further comprising at least one bushing at least partially contained within the sliding hammer, the bushing being dimensioned to accommodate the shaft.

8. A method of installing a seal using an installation tool, the method comprising:
aligning the seal with a seal-engaging component of the installation tool, wherein the installation tool includes a shaft defining a first end, a second end opposite to the first end, and a length defined between the first and second ends, such that the seal-engaging component is coupled with the shaft proximal to the first end of the shaft;
coupling the seal with the seal-engaging component based on an engagement of the seal with a first annular ring extending axially from a first surface of the seal-engaging component, wherein the seal-engaging component further includes a second annular ring extending axially from the first surface and concentric with the first annular ring, such that, based on the coupling of the seal with the seal-engaging component, a portion of the seal is radially disposed between the first annular ring and the second annular ring, wherein the seal-engaging component defines a cavity partially extending from a second surface of the seal-engaging component to the first surface, wherein the second surface is disposed opposite to the first surface;
positioning the seal and the installation tool adjacent to a seal installation location, such that the seal is axially positioned between the seal installation location and the seal-engaging component;
sliding a sliding hammer mounted on the shaft towards the first end of the shaft for applying a force to the seal-engaging component;
contacting an impact plate of the installation tool with the sliding hammer, wherein the impact plate is adapted to be received within a cavity defined by the seal-engaging component; and
installing the seal at the seal installation location based on the force applied to the seal-engaging component.

9. The method of claim 8 further comprising receiving the first annular ring within a groove defined by the seal for coupling the seal with the first annular ring.

10. A seal-engaging component associated with an installation tool for installing a seal, the seal-engaging component comprising:
a first surface;
a second surface disposed opposite to the first surface;
a first annular ring extending axially from the first surface, wherein the first annular ring is adapted to engage with the seal for coupling the seal with the seal-engaging component such that the seal is coaxial with the seal-engaging component; and
a second annular ring extending axially from the first surface and concentric with the first annular ring, such that, during the installation of the seal, a portion of the seal is radially disposed between the first annular ring and the second annular ring
wherein the installation tool further includes a shaft defining a first end, a second end opposite to the first end, and a length defined between the first and second ends, and wherein the seal-engaging component is coupled with the shaft proximal to the first end of the shaft,
wherein the installation tool further includes a sliding hammer mounted on the shaft and adapted to slide along the length of the shaft, and wherein, during the installation of the seal, the sliding hammer is adapted to apply a force to the seal-engaging component based on a sliding of the sliding hammer towards the first end of the shaft for installing the seal at a seal installation location,
wherein the seal-engaging component defines a cavity partially extending from the second surface toward the first surface,
wherein the installation tool further includes an impact plate adapted to be received within the cavity of the seal-engaging component, and wherein the sliding hammer is adapted to contact the impact plate for applying the force to the seal-engaging component.

11. The seal-engaging component of claim 10 , wherein,
the first annular ring defines a first diameter; and
the second annular ring defines a second diameter, the first diameter being greater than the second diameter.

12. The seal-engaging component of claim 10 , wherein the first annular ring is received within a groove defined by the seal for coupling the seal-engaging component with the seal.
