Abstract
The utility model relates to a vibration isolation structure of horizontal integral long-spring plates in an axial direction of a generator stator core. The vibration isolation structure comprises engine base inner rings arranged in the axial directions of an engine base, integral long spring plates and support ribs, wherein the integral long spring plates and the support ribs are uniformly arranged in the circumferential directions of the engine base. The engine base inner rings are welded on the engine base and are fixed with the integral long spring plates by welding. The integral long spring plates and the support ribs are fixedly connected through H-shaped cushion blocks and screws. The support ribs have dovetails and are connected with a stator core through the dovetails. The vibration isolation structure is advantaged in that the circumferential uniform elastic connection between the stator core and the engine base is achieved, good vibration effects and mechanical properties are achieved, security operation of a generator is ensured, the spring plates are thin in thickness and light in weight, and the vibration isolation structure is convenient in processing, manufacturing and installing and can reduce manufacturing cost.
Description
Technical field
The utility model relates to the long latch plate vibration insulation structure of the axial horizontal integral type of a kind of generator stator core, is used for improving the project organization of the vibration isolating effect between generator stator core and the support, belongs to the stator of steam turbine generator technical field.
Background technology
In the high-rating generator stator design, the latch plate structure is to realize out frame and the important component part that is connected unshakable in one's determination, and latch plate can not only support generator stator core and line rod, can also effectively cut off iron coring vibration to the support transmission.Latch plate generally is divided into two kinds, i.e. vertical latch plate and horizontal spring plate.Vertical latch plate structure is to utilize clamping ring to hold the integral body that forms unshakable in one's determination tightly by support bar, clamping ring is connected with screw with vertical latch plate and adds welding, latch plate also is connected with screw with support and adds welding, iron core is fixed in the support, its shortcoming is that clamping ring quantity is many, structure is numerous and diverse, and weight is big, and the difficulty of processing and manufacturing is big; The long latch plate structure of horizontal integral type is that support bar is connected with unshakable in one's determination by dovetail, support bar is connected with screw by H type cushion block with latch plate, boxing connects in latch plate and the support, its advantage is designs simplification, and is in light weight, is conducive to enhance productivity and reduce manufacturing cost, especially be fit to the design of segmented stator structure, alleviate the stator hauled weight, realize the transportation of railway matrix body car, reduce cost of railway traffic greatly.
Summary of the invention
The purpose of this utility model provides a kind of project organization that can effectively improve the vibration isolating effect between generator stator core and the support, and be conducive to alleviate generator unit stator weight, not only guarantee the security of operation of generator, and reduced generator manufacturing, cost of transportation.
In order to achieve the above object, the technical solution of the utility model provides the long latch plate vibration insulation structure of the axial horizontal integral type of a kind of generator stator core, it is characterized in that, comprise the long latch plate of integral type and the support bar that encircle in the support that is arranged on the support axial direction and evenly be arranged on the support circumferential direction, boxing is connected on the support in the support, ring is fixing by welding with the long latch plate of integral type in the support, fixedly connected with screw by H type cushion block between the long latch plate of integral type and the support bar, support bar has dovetail, and support bar is connected with stator core by dovetail.
The utility model has the advantages that and realized circumferentially evenly elasticity connection between stator core and the support, have better vibration isolating effect and mechanical property, guarantee the security of operation of generator, and latch plate thinner thickness, in light weight, processing and manufacturing and simple installation are conducive to reduce manufacturing cost.
