Abstract
The invention relates to an integrated cantilever rotor structure, which comprises a generator rotor, a centrifugal compressor impeller, sealed grate teeth and a radial turbine impeller which are arranged on a central pull rod in sequence. One side of the centrifugal compressor impeller is connected with the radial turbine impeller through the sealed grate teeth in end face matching mode, the centrifugal compressor impeller and the radial turbine impeller are arranged in back-to-back mode, and the other end of the centrifugal compressor impeller is connected with the generator rotor. The integrated cantilever rotor structure has the advantages of being simple in structure, small in volume and capable of enabling a unit structure to be simple, usage to be reliable, failure rate to be low and both manufacture cost and maintenance cost to be reduced.
Description
Technical field
The present invention relates to a kind of integral type cantilever rotor structure.
Background technique
Normally adopt retarder or coupling to be connected between the generator of Gas Turbine Generating Units and the gas generator.The miniature gas turbine generator set is the new technology that develops rapidly in recent years, and characteristics are that volume is little and generating unit speed is high.At present successful development high-speed permanent magnet motor (number of patent application: 201020502094.X), its working speed can reach 60000r/min, can with the gas generator direct connection, need not slow down just can normal power generation.Though do not need speed reducer, use conventional access node structure, like coupling etc., can cause unit complicated in mechanical structure, volume big, and reliability is lower in the working procedure, a large amount of power consumpitons are on mechanical transmission.
Summary of the invention
The purpose of this invention is to provide a kind of integral type cantilever rotor structure, when realizing that generator and gas generator carry out direct connection, solve the deficiency of fuel engine power generation set structure, make gas turbine structure simple, volume is little, and power loss is few.
Technological scheme of the present invention is: described integral type cantilever structure is included in generator amature, the centrifugal compressor impeller that is arranged in order on the center pull rod, the comb tooth of obturaging, radial turbine impeller; One side of described centrifugal compressor impeller is connected with the radial turbine impeller through the comb tooth of obturaging with the mode that end face cooperates; Described centrifugal compressor impeller and radial turbine impeller are form back-to-back; The other end of centrifugal compressor impeller is connected with generator amature; Described center pull rod runs through generator amature, centrifugal compressor impeller, obturage comb tooth and radial turbine impeller; One end is provided with boss and cooperates with the step of radial turbine impeller endoporus, and the other end is provided with screw thread and fixes through locking nut, and the both sides of described generator amature are respectively arranged with block bearing.
The present invention links together three big rotatable parts through center pull rod, through the boss and the nut of pull bar itself each parts is fixed, and the end-face friction driving torque through each parts combines.In this micro fuel engine power generation unit; The electricity generating device of unit is a high-speed permanent magnet motor; Centrifugal compressor impeller, radial turbine impeller and the coaxial high-speed rotation of generator amature; Send high-frequency alternating current, supply the user to use after the frequency conversion, and in starting process, start unit as starter motor with permanent magnet generator.This structure can realize rotor speed about 60000 rev/mins, and the power of the assembling unit is about 100kW.
The present invention has replaced original retarder or coupler structure through the center pull rod structure; Realized the direct connection between generator and the gas generator; Make simple in structure; Volume is little, adopts the cantilever structure of centrifugal compressor impeller, radial turbine impeller " back-to-back " can shorten jib-length, reduces the turbine wheel vibration amplitude; Described micro fuel engine machine group rotor is a coaxial configuration, can make set structure simple, uses reliably, and rate of fault is low, and manufacture cost and maintenance cost all can reduce.
