![]() ![]() In a preferred embodiment to be described hereinafter in greater detail, an overspeed trip mechanism in accordance with the present invention includes a collar adapted to be axially received on and fixed relative to a shaft.Ī trip member of conventional design is located exteriorly of the collar. SUMMARY OF THE INVENTION The present invention has as one of its primary objectives the provision of an improved overspeed trip mechanism which can be axially mounted on a turbine shaft or the like without the need to resort to expensive and time consuming machining operations.Ī further objective of the present invention is the provision of a highly reliable yet relatively inexpensive trip mechanism which can be rapidly installed on existing equipment in the field. ![]() This usually makes it impractical to attempt retrofitting turbines in the field with new and improved trip mechanisms, because in order to do so, the turbines must be dismantled in order to gain proper access to the turbine shafts. The eccentric ring is movable radially relative to the collar between a first position spaced from the trip member and a second position in contact therewith.Ī spring is arranged between the ring and the collar to yieldably urge the ring into its first position.įield of the Invention This invention relates to an overspeed trip mechanism for a rotary shaft which typically comprises the output shaft of a steam turbine.ĭescription of the Prior Art Turbine overspeed trip mechanisms are well known in the art.Ĭonventionally, installation of such mechanisms entails precise drilling andor machining of the shafts on which they are mounted. ![]() The pin member 42 protrudes radially inwardly from the ring 32 and is slidably received in a first radial bore 44 in the collar 14.Īn eccentric ring surrounds and is connected to the collar for rotation therewith. ![]() Coppus Turbine Instruction Download The NewestĬoppus Turbine Instruction Download The Newestįor the best experience we suggest that you download the newest version of a supported browser. ![]()
