Description
Technical field
This utility model is a kind of attachment means, and especially a kind of engine turbine is connected torsion transmitter with compressor rotor, it is possible to achieve the turbine rotor of gas-turbine unit and compressor rotor is coupled together and transmits axial force and moment of torsion.
Background technology
In gas-turbine unit, compressor rotor work process can produce axial force forward, the generally up to the most hundreds thousand of cattle of tens thousand of newton pauses, and turbine rotor can produce axial force backward, the most hundreds thousand of cattle of tens thousand of newton can be up to equally pause, if both axial forces are undertaken by electromotor ball bearing completely, it is likely to cause ball bearing to destroy, rotor fails, therefore, need a kind of device, turbine rotor is coupled together with compressor, two rightabout active forces are balanced out major part, thus protect ball bearing safety, this device the most also to play the effect that turbine torque passes to compressor.Connecting torsion transmitter kind at present more, being broadly divided into following 3 kinds: 1st kind is pin or key transmission moment of torsion, and threaded, this apparatus structure is simple, but torsion pass moment is less；2nd kind uses end tooth torsion pass and carries out self-centering, and center pull rod connects, and the moment of torsion of this structure transmission is big, feels relieved accurately, but part processing precision is high, and material requirements is high, and processing cost is high, and assembling needs Special pull machine, assembles complicated cost the highest.3rd kind for spline torsion pass and utilizes flank to feel relieved, and threaded, this structure can transmit high torque, advantage of lower cost, but needs to design axial attachment structure, and the parts that device comprises are many and structure is complicated, and complexity is decomposed in assembling, and operability is the highest.
Summary of the invention
The purpose of this utility model is to provide a kind of engine turbine and is connected torsion transmitter with compressor rotor, compressor rotor and the connection of turbine rotor and the transmission of bigger moment of torsion can be realized, and the moment of torsion with transmission is big, parts machining required precision is the highest and simple in construction, advantage that processing cost is low, there is stable connection simultaneously, compact conformation, assembles and dismantles simple, easy to use etc..
Concrete technical scheme of the present utility model is: engine turbine is connected torsion transmitter and includes compressor rotor, turbine rotor, attachment screw with compressor rotor, described compressor rotor is provided with internal spline, turbine rotor is provided with external splines and coordinates with the internal spline of compressor rotor, attachment screw one end is provided with screw thread and is arranged in compressor rotor inner chamber, the other end be provided with step and be stuck in turbine rotor inner chamber step on, the stepped locations of described attachment screw is additionally provided with external splines, and coordinates with the internal spline arranged on turbine rotor inner chamber；The described spline sections on attachment screw is hollow-core construction, and axially has groove, and described groove is uniform 6.
During this utility model assembling, first attachment screw is loaded from turbine rotor inner chamber, again turbine rotor is inserted in compressor rotor, and make the spline of compressor rotor and turbine rotor match, play the effect of torsion pass, now use frock by the external splines radial compression of attachment screw, the groove due to this external splines radial design, it radially can shrink, diameter reduces, and disengage with the internal spline on turbine rotor, then screw it is rotationally connected, so that being threaded in compressor rotor inner chamber on attachment screw, then the radial force of attachment screw external splines is discharged, attachment screw returns to original position, attachment screw is made to coordinate with turbine rotor internal spline, complete to install.During dismounting, first by the external splines radial compression of frock just attachment screw, departing from turbine rotor internal spline, be then rotatably connected screw, is pulled down by attachment screw from compressor rotor, the most just can turbine rotor and compressor rotor be separated.
This utility model is operationally, turbine rotor is by axial tension backward, making attachment screw and turbine rotor fit at step and compress, the axial force that turbine rotor is passed over by attachment screw passes to compressor rotor by screw thread, and prevents compressor rotor and turbine rotor from disengaging.For preventing screw thread from operationally rotating disengagement, attachment screw is connected with turbine rotor by spline, to ensure the synchronous axial system of itself and rotor-support-foundation system, thus reached both to have delivered between two rotors moment of torsion, in turn ensure that relative invariant position, serve the effect connecting torsion pass, and in this way, compressor rotor axial force forward and turbine rotor axial force major part backward is cancelled out each other, thus axial load when alleviating the work of compressor ball bearing.This utility model have employed spline and connects, and positioned by screw thread and step, there is transmission moment of torsion big, positioning reliable advantage, meanwhile, this utility model only designs an attachment screw, and it is provided with axial groove, and by compressing the position of axial groove, installation and removal can be realized smoothly, there is simple in construction, stable connection, low cost, reliable operation, the feature such as easy for installation.
