Abstract
The lower half of the turbomachine casing is mounted so as to retain the casing half in a set horizontal plane despite thermal expansions and contractions. To this end, the support arrangement at one end of the casing half includes vertically disposed rods which have a coefficient of thermal expansion less than that of the casing as well as covers which are secured to the casing and rest on the rods in order to transfer the weight of the casing to the rods. When heated, the rods expand upwardly while the covers expand downwardly. The two expansion effects cancel each other so that the plane of the lower casing half is maintained set.
Claims16
In combination with a turbomachine having a casing split along a horizontal median plane, a lower half of said casing having a plurality of lugs extending therefrom, each lug having an aperture therethrough;
- a support arrangement for defining the axial position of said lower casing half including vertically extending rods, each rod being disposed within an aperture of a respective lug and having a coefficient of thermal expansion less than that of said casing and covers secured to an upper surface of said lugs and resting on said rods to transfer the weight of said turbomachine casing to said rods.
A support arrangement for supporting a turbomachine casing on a bedplate comprising
- a bearing block having a recess therein;
- a sliding member slidably mounted in said recess of said bearing block for sliding in a horizontal plane,
- a vertical sleeve mounted on said sliding member, and
- a vertical rod supported on said sliding member within said sleeve, said rod having a top surface in a horizontal plane located above said sleeve to receive at least a portion of the weight of a turbomachine casing.
In combination with a turbomachine casing and a bedplate;
- a support arrangement comprising
- a bearing block mounted on said bedplate and including a recess therein;
- a sliding member slidably mounted in said recess of said bearing block for sliding in a horizontal plane;
- a vertical sleeve fitted in said casing and having a coefficient of thermal expansion equal to the coefficient of thermal expansion of said casing, said sleeve being mounted in said sliding member for transmitting axial thrusts and transverse movements of said casing to said sliding member;
- and
- a vertical rod supporting on said sliding member with said sleeve, said rod having a top surface in a horizontal plane located above said sleeve to receive at least a portion of the weight of said casing.
In combination with a turbomachine casing having a lower casing half having a joint face in a first horizontal plane and at least one lug extending therefrom;
- a bed plate;
- and a support arrangement for maintaining said joint face in said plane during thermal expansion, said support arrangement including a cover secured to said lug and having a recess, and a vertical rod having an upper surface abutting against said cover within said recess of said cover and in a second horizontal plane spaced above said first horizontal plane to receive at least a portion of the weight of said casing, said rod passing through an aperture in said lug to transmit the weight of said casing to said bed plate.
In combination with a turbomachine casing having a lower casing half having a joint face in a first horizontal plane and at least one lug extending therefrom;
- a bed plate;
- and a support arrangement for maintaining said joint face in said plane during thermal expansion, said support arrangement including a cover secured to said lug and having a recess, a vertical rod having an upper surface within said recess of said cover and in a second horizontal plane spaced above said first horizontal plane to receive at least a portion of the weight of said casing, said rod passing through an aperture in said lug to transmit the weight of said casing to said bed plate and at least one bearing block on said bed plate and a sliding member slidably mounted on said bearing block in a horizontal plane, said rod being supported on said sliding member.
