Abstract
The invention provides a tool special for assembling a gas turbine pull rod-type rotor disc. The tool is a screw jack which comprises a nut and a stud matched with each other; and the bottom of the stud is fixedly arranged on a thrust bearing. During assembly of the gas turbine pull rod-type rotor disc, a plurality of special tools are symmetrically arranged between a disc to be assembled and a disc on an assembling surface, and an upper surface of each special tool supports the disc to be assembled; the nut of each special tool is held by a spanner, and the studs of all the special tools are synchronously rotated at a constant speed by another spanner simultaneously. Therefore, the synchronous jacking and descending of the disc above the special tools are realized. The tool special for assembling the gas turbine pull rod-type rotor disc has the advantages of simple and reasonable structural design, and simple and convenient manufacture and operation; the using method has the advantages of simpleness, convenience, easy operation, and strong controllability; and the tool can freely adjust the size of the stud and nut according to the size of the placement position so as to meet the requirements on different occasions.
Description
Technical field
The present invention relates to the support in a kind of small space, specifically a kind of draw bar type rotor disk of gas turbine connects and joins jack and the using method thereof of using in the process.
Background technology
Gas turbine pull rod type rotor is a kind of like this rotor form: the gas turbine pull rod type rotor body is not a whole heavy forging, fits over a kind of rotor block that forms together but connect by parts such as spindle nose, wheel disc, tween drive shafts.
Wherein, the single-stage wheel disc of gas turbine pull rod type rotor needs to become in advance winding to prepare, and connects with the rotor miscellaneous part and joins.Connect timing at wheel disc, wheel disc fits over by seam interference fit and connecing with wheel disc, is connecing timing, requires the wheel disc can not deflection, in order to avoid cover is partially, and the out of reach designing requirement.Therefore, connect timing, require the seam of top wheel disc is pressed in the seam of following wheel disc uniformly, thereby prevented that wheel disc from overlapping fashionable deflection.
Because after the wheel disc stack, the distance between wheel disc is very little, general hand jack all can't be placed; And during descending jack, on one side require the operator to fall jack, Yi Bian monitor the speed that dial measuring gauge is controlled decline, therefore, require to use a kind of jack of being convenient to closely operate.Yet, at present domestic still without any coming out about this jack that is adapted at operating in two small spaces between the wheel disc.Because the restriction of draw bar type rotor disk of gas turbine assembly technique, in the automotive gas turbine that state internal-combustion gas turbine engine producer produces, its pull rod type rotor is generally external introduction, directly uses the pull rod type rotor that Product Precision requires that conforms with of rare independent research, production.Like this, so that productive costs increases, be unfavorable for the market-oriented requirement of product.Therefore, need a kind of special tool of operating in two small spaces between the wheel disc of being adapted at of independent research, make it to be applicable to the assembling of draw bar type rotor disk of gas turbine.
Summary of the invention
The object of the invention is to: a kind of special tool and using method thereof for the assembling draw bar type rotor disk of gas turbine is provided, makes this special tool adapt to the high-precision requirement of rotor disk assembling and the restriction of size.
The technical solution adopted in the present invention is:
A kind of special tool for the assembling draw bar type rotor disk of gas turbine is a kind of screw jack, has knock hole corresponding to position and seam on the described draw bar type rotor disk of gas turbine, and this knock hole has the with it locating dowel pin of correspondence of thickness; Described jack comprises nut and the double-screw bolt that cooperatively interacts, and the bottom of double-screw bolt is fixedly mounted on the thrust baring; Should be used for the using method of assembling draw bar type rotor disk of gas turbine special tool, may further comprise the steps:
(1) at first, insert locating dowel pin in the knock hole on the wheel disc on fitting surface surface;
(2) assembling of the locating dowel pin that the knock hole matching step (1) of wheel disc to be assembled inserted is pressed in the seam of wheel disc on fitting surface surface the seam of wheel disc to be assembled uniformly;
(3) with several special tools, be arranged symmetrically with between the wheel disc that is installed in wheel disc to be assembled and fitting surface surface, make the upper surface of described special tool support wheel disc to be assembled;
(4) nut of each special tool is held with spanner, with the another spanner simultaneously synchronous uniform velocity rotate the double-screw bolt of all special tools, realize synchronous jack-up and the decline of wheel disc to be assembled.
The bottom of described double-screw bolt has six-sided head to be supported, and double-screw bolt is installed in the thrust baring by supporting corresponding back-up block with the double-screw bolt six-sided head.
The beneficial effect that the present invention produces is:
Use and verify by scene actual, this special tool structure design for the assembling draw bar type rotor disk of gas turbine provided by the invention is simple, rationally, makes and easy and simple to handle, well satisfied requirement.This special tool can according to the size of placement location, freely be adjusted the size of double-screw bolt, nut, with meet requirements; Using method is easy, easy to operate, and controllability is strong; Effectively reduce the productive costs of gas turbine rotor, make it to occupy in market larger competitive power.
