Abstract
The utility model relates to a sealing device between an outer gate barrel and a control ring of a bulb tubular turbine. An inner ring groove and an outer ring groove are respectively arranged at the end face of the outer gate barrel; the control ring is arranged on the outer gate barrel; steel balls are arranged between the control ring and the outer gate barrel; a pressing plate is pressed on the steel balls; and forming rubber strips are glued in the inner ring groove and the outer ring groove by glue respectively. The sealing device has the advantages that 1) hundreds of steel balls are immersed in lubricating oil; 2) the control ring is guaranteed to be flexible in running and not to be clamped; 3) the conventional seal has no self compensating function after being abraded, and the lubricating oil is leaked due to the insufficient compactness quantity, however, the structure of the sealing device provides a self compensating function, so that the sealing device is long in service life; and 4) the structure of the sealing device is simple, so that the sealing device is convenient to machine and install.
Description
Technical field
The utility model relates to the seal arrangement between a kind of bulb through-flow turbine outer gate barrel and the control ring.
Background technique
The control ring of bulb through-flow turbine is arranged on the outer gate barrel, and hundreds of steel balls of installing form a huge rolling bearing between its internal surface and outer gate barrel outer surface, so that control ring is when rotating, friction factor is little, rotates flexible.The rolling bearing diameter is generally all bigger, and needs a large amount of yellow glycerine lubrications.Unit is at run duration, and control ring is to-and-fro motion constantly, and phase mutual friction between steel ball makes lubricant oil reveal along the gap between two steel parts, has both influenced the operation of unit, again befouling environment.
Summary of the invention
The purpose of this utility model provides seal arrangement between a kind of bulb through-flow turbine outer gate barrel and the control ring, reduces oil leakage when making unit operation, influences unit rotation flexibility, befouling environment.The purpose of this utility model realizes by following structure: the utility model is the seal arrangement between a kind of bulb through-flow turbine outer gate barrel and the control ring, the outer gate barrel end face has inner ring groove and outer ring groove respectively, control ring is arranged on the outer gate barrel, it between control ring and outer gate barrel steel ball, pressing plate is fitted on the steel ball, and the moulding rubber strip is bonded in respectively in inner ring groove and the outer ring groove with adhesive glue.The utility model advantage is: guarantee that 1) hundreds of steel balls all are immersed in the lubricant oil; 2) guarantee that control ring goes slick, not hair fastener; 3) conventional seals is after being worn, and no self compensation ability is because of the not enough oil leakage that causes of sealing crush; The utlity model has the self compensation ability, promptly " the tip of the tongue " of the ligulate Stamping Steel Ribbon of inner ring and outer ring has certain pressure to it all towards steel ball after the control ring installation, makes its compacted, distortion, makes " the tip of the tongue " of Stamping Steel Ribbon hold out against control ring.Stamping Steel Ribbon is worn behind unit operation, and " the tip of the tongue " part of Stamping Steel Ribbon will be thrown away under the effect of its elastic force and can hold out against control ring, play auto-compensation; Long service life; 4) simple in structure, processing and peace are bored all convenient.
