Abstract
The invention discloses a coupling for 30MW steam turbo generator testing, comprising key 2, half coupling I3, half coupling II4, bolt 6, check ring 7, nut 8, clamping ring 9 and pin 10. Half coupling I3 is mounted on the rotor 1 of steam turbo generator and half coupling II4 is mounted on the shaft end 5 of dragging machine. Check ring 7 is fixed on the top of rotor shaft 1 of steam turbo generator and bolt 6 is set on the top of rotor shaft 1 of steam turbo generator so as to fix the checking ring to the rotor shaft top. Pin 10 is fixed on the half coupling II4 by clamping ring 9. When two half couplings is combined together, the other end of pin 10 is fixed by nut 8 on the half coupling I3. The invention can satisfy the torque and accuracy demand of 30MW steam turbo generator testing. The whole machine test of 30MW steam turbo generator and dynamic balance test of the rotor are accomplished on the prior equipment and testing platform. It is provided with simple structure, strong application and low cost so on.
Description
Technical field
The present invention relates to a kind of steam turbine generator type and have a try to test and use coupling, particularly a kind of 30MW steam turbine generator type is had a try to test and is used coupling.
Background technique
The 30MW steam turbine generator needs to carry out dynamic balance test of rotor before dispatching from the factory, and is bigger because 30MW vapour is sent out acc power, and the moment of torsion that corresponding coupling is transmitted is also bigger, and the test requirements document precision is higher, and used in the past coupling can not satisfy test requirements document.
Summary of the invention
Purpose of the present invention is exactly can not satisfy 30MW vapour at traditional coupling to send out the problem that the machine rotor dynamic balance running requires, and provides a kind of 30MW steam turbine generator type to have a try to test and has used coupling.
The objective of the invention is to be achieved through the following technical solutions: the steam turbine generator type is had a try to test and is used coupling, comprises key, half-coupling I, half-coupling II, screw, ring washer, nut, trim ring, pin.Half-coupling I is set on the rotor of steam turbo generator, half-coupling II is set on the pull-over gear axle head, ring washer is fixed in rotor of steam turbo generator axle top, prevent that key from scurrying out, screw is installed in rotor of steam turbo generator axle top, with ring washer tightly on the rotor shaft top, pin is fixed on the half-coupling II by trim ring, when two half-couplings fashionable, the pin the other end is fixed by the nut on the half-coupling I.
The present invention is an elastic ring column pin shaft coupling.It is bigger that 30MW vapour is sent out acc power, and the moment of torsion that corresponding coupling is transmitted is also bigger, and elastic dowel pin shaft coupling can meet the demands well.
The material of pin of the present invention is Alloy Constructional Steel (35CrMo).Consider the characteristics that the rotary axis transmitting torque is big, the selection of material is Alloy Constructional Steel (35CrMo), and its mechanical property is improved greatly.
Material selection of the present invention be forged steel 45.Consider the characteristics that the rotary axis transmitting torque is big,,, can not satisfy test requirements document, therefore adopt forged steel 45 as the coupling material because its tensile strength is lower if adopt general coupling material.
30MW steam turbine generator type of the present invention is had a try to test and is used coupling, select the elastic coupling mode, adopting forged steel 45 is material, select the pin of alloy structure steel for use, can satisfy 30MW steam turbine generator type has a try and tests requirement to moment of torsion and precision, the complete machine type that can utilize existing equipment and test platform to carry out the 30MW steam turbine generator is had a try and is tested and dynamic balance test of rotor, has advantages such as simple in structure, practical, with low cost.
