Machinery mount

A mount for positioning a machine on a mounting surface, the machine including a machine base having an aperture therein for receiving the mount, the mount comprising:

• a metal base plate having a planar lower surface for engagement with the mounting surface;
• an outwardly projecting dimple portion secured to the base plate, the dimpleportion formed from metal and defining a hemispherical outer surface and an inner surface having a nominal inner surface diameter defining an interior cavity spaced between the dimple portion and the planar lower surface, the dimple portion including a hole through an upper portion thereof;
• a stud having a stud axis and an upper threaded portion projecting upwardly from the base plate for passing through the aperture in the machine base, and a lower shaft portion passing through the hole in the dimple portion;
• and
• a stud support fixedly secured to the stud, the stud support including a central axial passageway therethrough for receiving the lower shaft portion of the stud, an upper portion for at least substantial sealing engagement with the stud, a lower curved surface configured for sliding engagement with the hemispherical outer surface of the dimple portion such that the stud may pivot with respect to the base plate, the lower curved surface of the stud support having a lower surface nominal diameter of at least 90 percent of the nominal inner surface diameter, and an injection port spaced axially between the upper portion and the lower curved surface and extending radially inward from an exterior surface of the stud support into fluid communication with the central axial passageway for injecting a sealant through the central axial passageway and into the interior cavity in the dimple portion.

A mount for positioning a machine on a mounting surface, the machine including a machine base having an aperture therein for receiving the mount, the mount comprising:

• a metal plate having a planar lower surface for engagement with the mounting surface;
• an upwardly projecting dimple portion secured to the base plate, the dimple portion formed from metal and defining a hemispherical outer surface, a generally hemispherical inner surface having a nominal inner surface diameter within a plane of the planar lower surface, and an interior cavity spaced between the inner surface and the planar lower surface, the dimple portion including a hole through an upper portion thereof;
• a stud including an upper threaded portion projected upwardly from the base plate for passing through the aperture in the machine base, a lower shaft portion passing through the hole in the dimple portion, and a lower curved surface for sliding engagement with the hemispherical outer surface of the dimple portion such that the stud may pivot with respect to the base plate and vertical spacing between the metal base plate and a portion of the stud passing through the hole is the dimple portion remaining fixed for vertically fixing the machine relative to the mounting surface;
• the lower curved surface having a lower surface nominal diameter of at least 90 percent of the nominal inner surface diameter;
• and
• a locking member secured to a lower end of the lower shaft portion for preventing the lower shaft portion from passing upward through the hole in the dimple portion.

A method of manufacturing a mount for positioning a machine on a mounting surface, comprising;

• deforming a metal plate to form a base plate having a planar lower surface for engagement with the mounting surface and an upwardly projecting dimple portion being integral with and of the same material as the planar lower surface, the dimple portion defining a generally hemispherical outer surface, a generally hemispherical inner surface having a nominal diameter, and an interior cavity spaced between the dimple portion and the lower surface;
• forming a hole through an upper portion of the dimple portion;
• providing a stud having an upper threaded portion and a lower shaft portion having a diameter significantly less than a diameter of the upper threaded portion;
• forming a stud support including a central passageway therein and a lower curved surface circumferentially about the central passageway the curved lower surface having a nominal diameter of at least 90% of the nominal inner surface diameter;
• fixedly securing the stud to the stud support such that the lower shaft portion of the stud passes through the central passageway in the stud support;
• passing the lower shaft portion of the stud through the hole in the upper portion of the dimple portion, such that the upper threaded portion projects upwardly from the base plate and the curved lower surface of the stud support is in sliding engagement with the curvilinear outer surface of the dimple portion;
• and
• securing a locking member to a lower end of the lower shaft portion for preventing the lower shaft portion from passing upward through the hole in the dimple portion.
