Movable elastic coupling of microminiature turbojet engine

Abstract

The invention discloses a microminiature turbojet engine movable elastic coupling which comprises a generator connecting end, a corrugated pipe section, an engine connecting end and a clamping piece, the generator connecting end is connected to one end of the corrugated pipe section, and the engine connecting end is connected to the other end of the corrugated pipe section. And clamping pieces are arranged in the generator connecting end and the engine connecting end. A red copper clamping ring is arranged to wrap the main shaft, the main shaft is protected from being damaged by double-hard contact in the installation and starting process, and vibration is reduced. The elastic coupling body is provided with 180-degree symmetrical threaded holes, clamping ring set screws of the same specification are adopted, redundant unbalance can be counteracted, the coupling does not increase rotor unbalance, system stability is facilitated, a coaxial sleeving type installation method is adopted, the number of parts is small, installation is easy, the spindle centering allowance is large, operation is easy, and installation efficiency is high. The elastic coupling is high in torsion resistance, impact-resistant, small in vibration, high in elasticity, free of back clearance and free of missing rotation in forward and reverse rotation.

Description

technical field [0001] The invention relates to the field of couplings, and more particularly, to a movable elastic coupling of a miniature turbojet engine. Background technique [0002] With the development of the industrial economy, the coupling industry has developed faster and faster, and a complete industry has been formed. According to statistics, my country's coupling industry has formed a large, medium and small enterprise scale. In the turbojet engine and gas turbine power generation industry, the coupling is also one of the most important components. In large gas turbine generators, most of the existing couplings operate in a low-speed environment, requiring large reduction devices to slow down. After that, the mechanical work is transmitted through the low-speed coupling. The overall structure is huge, which is too bulky, the loss is too large, and the efficiency is low. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present inventi...
