Abstract
The present disclosure provides an apparatus for lubrication of a hinge on a work machine. The hinge includes a first member such as a first boom arm and a second member such as a second boom arm. The hinge further includes a pin hingedly linking the first and second members. The pin has a path therein having a first portion that extends axially. The hinge further includes a port in fluid communication with the path. The port is radially offset by a fixed distance and fixed orientation from the first portion within the pin.
Claims20
A hinge on a work machine including:
- a first member;
- a second member;
- a pin hingedly linking the first and second members, the pin having a fluid path therein, the path having a first portion that extends axially therein, and
- a port in fluid communication with the path and operable to couple to a fluid supply, the port being radially offset by a fixed distance and fixed orientation from the first portion.
The hinge of claim Error! Reference source not found., wherein the path includes a second portion outside of the hinge pin, the second portion extending radially relative to the generally cylindrical pin.
A hinge lubrication apparatus including:
- a first hinge member,
- a second hinge member,
- a hinge pin operable to hingedly couple the first and second members, the hinge pin having a lubrication path therein;
- a lubricant supply path operable to supply lubricant to the lubrication path via a connection port fixed to the first hinge member that is in fluid communication with the lubrication path, the connection port being positioned such that connection thereto by the lubricant supply path is on an interior of the first hinge member.
A hinge pin including:
- a pin body;
- and
- a second body having:
- a first portion axially aligned with the pin body;
- a second portion radially displaced relative to the first portion;
- and
- a lubrication path that extends from the first portion to the second portion.
A hinge lubrication apparatus for a work machine including:
- a first hinge member,
- a second hinge member operably coupled to a work machine cab via the first hinge member;
- a hinge pin operable to hingedly couple the first and second members;
- and
- a lubrication path including a lubrication port fixed to the first hinge member, a first portion within the hinge pin, and a second portion extending between the lubrication port and the first portion;
- the second portion defining a rigid path.
