Description
Technical field
The present invention relates to the support in a kind of small space, specifically is that a kind of draw bar type rotor disk of gas turbine connects and joins jack and the using method of using in the process thereof.
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 winding to prepare in advance, 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 manual jack all can't be placed; And during the decline jack,,, therefore, require to use a kind of jack of being convenient to closely operate Yi Bian monitor the speed that dial measuring gauge is controlled decline on one side require the operator to fall jack.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 is produced, its pull rod type rotor is generally external introduction, directly uses the pull rod type rotor that conforms with the product accuracy requirement of rare independent research, production.Like this, make productive costs increase, 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 objective of the invention is to: a kind of special tool and using method thereof that is used to assemble 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 that is used to assemble draw bar type rotor disk of gas turbine is a kind of spiral jack, and 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.
The bottom of described double-screw bolt has six-sided head to be supported, and by supporting cooresponding back-up block with six-sided head, is installed in the thrust baring.
A kind of using method that is used to assemble the draw bar type rotor disk of gas turbine special tool may further comprise the steps:
(1) have cooresponding knock hole in position and seam on the described draw bar type rotor disk of gas turbine, this knock hole has the cooresponding with it locating dowel pin of thickness; At first, insert locating dowel pin in the knock hole on the wheel disc on fitting surface surface;
(2) knock hole with wheel disc to be assembled cooperates the locating dowel pin assembling, and the seam of wheel disc to be assembled is pressed in the seam of fitting surface surface wheel disc uniformly.
(3) with the described special tool of several claims 1, symmetric arrangement is installed between the wheel disc on wheel disc to be assembled and fitting surface surface, makes the upper surface of described special tool support wheel disc to be assembled;
(4) nut of each special tool is held with spanner,, realized the synchronous jack-up and the decline of wheel disc to be assembled with the synchronous simultaneously double-screw bolt that at the uniform velocity rotates all special tools of another spanner.
The beneficial effect that the present invention produced is:
Use and verify by scene actual, this special tool structure design that is used to assemble 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 freely be adjusted the size of double-screw bolt, nut, with meet requirements according to the size of placement location; Using method is easy, easy to operate, and controllability is strong; Effectively reduce the productive costs of gas turbine rotor, made it on market, to occupy bigger competitive power.
