Abstract

An integral mechanical governor for controlling the speed of prime movers, such as steam turbines is disclosed as a separate structure that can be mounted on and coupled to the shaft of the associated prime mover. The device includes a housing having at least one end opening and closure means for the open end of the housing, the housing and closure defining a governor assembly chamber and a sump for lubricating fluid. The end wall remote from the open end has an inboard bearing means for rotatably mounting a driven shaft disposed to extend from the governor assembly chamber through the bearing to the exterior of the housing to permit said driven shaft to be coupled to the shaft of the prime mover when the integral mechanical governor is mounted thereon in assembled position. A substantially conventional governor assembly is mounted in the governor assembly chamber of the housing and a self contained lubrication system is provided in the housing which includes an oil ring rotatably disposed on the governor assembly and sized to pass through the lubricating fluid in the sump so as to throw and splash the lubricating fluid towards the upper end of the governor assembly chamber and a portion is conducted by a transfer member and ports to lubricate the inboard and outboard bearings of the integral mechanical governor. A filter is provided on the transfer member to filter the lubricant delivered to the bearings.

Dependent claims

An integral mechanical governor for use with a prime mover having a rotatable shaft thereon;

a. a housing forming a governor chamber and a lubricating fluid sump and having at least one open end, and closure means detachably connected to the open end thereof,
b. means on the inboard end of the housing remote from the open end for connecting the mechanical governor in assembled position on the prime mover,
c. bearing means in the end wall of the housing on the inboard side thereof,
d. a driven shaft rotatably mounted in said bearing means and extending in the axial line of the housing from the interior of the governor chamber in said housing to the exterior of the housing to permit the driven shaft to be coupled to the shaft of the prime mover,
e. governor weight holder means fixedly connected to the end of the driven shaft in the governor chamber and rotatable therewith, and weight means pivotally connected to the governor weight holder,
f. outboard bearing means connected in said end closure in the axial line of said inboard bearing means,
