Technical Field

The invention relates to a misalignment adjustable coupling, in particular to an experimental device of an experimental table for researching misalignment vibration of a rotor coupling.

Background

Rotating machines are widely used in various fields, small rotating parts in automobiles and large rotating parts in steam turbine rotors in power plants. The rotating machinery must use a mechanical device of a coupler when transmitting torque, and the coupler has a certain amount of misalignment due to the performance of materials, manufacturing errors and installation errors in the production process. The presence of the misalignment can cause shafting vibration, the long-time presence of the vibration can cause damage to the shafting, and the damage of a large amount of noise and the like can affect the normal operation of equipment. Therefore, it is necessary to study and test the misalignment amount of the coupling and the characteristics of the misalignment type.

Disclosure of Invention

The invention aims to solve the problems of the research on the misalignment type of a coupler in a rotating machinery experiment table and a misalignment change method by using a non-centering adjustable coupler. The experimental device simulates the change of the coupler to the neutral position by using a sliding adjustable device and a mechanical structure such as a bolt, and the like, thereby achieving the stepless adjustment of the coupler to the neutral position and the disassembly-free adjustment in the experimental process.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a not centering volume adjustable shaft coupling, the device includes, parallel misalignment control bolt, parallel misalignment fixation nut, off-angle misalignment control bolt, parallel misalignment slide hole, parallel misalignment bolt fastening screw, shaft coupling fixing screw, off-angle misalignment control screw. When parallel misalignment is simulated, the parallel misalignment bolt (1) passes through the parallel misalignment sliding hole (4) and is screwed into the parallel misalignment bolt fixing screw hole (5) and is locked and fixed by the parallel misalignment fixing nut (2). When the deflection angle is not centered, the deflection angle misalignment control bolt (3) penetrates through the deflection angle misalignment control screw hole (7) and is screwed into the device, and then is fixed on the experimental table rotor through the coupling fixing screw hole (6).

The misalignment-adjustable shaft coupler is characterized in that a parallel misalignment bolt (1) is screwed into a parallel misalignment bolt fixing screw hole (5) to limit the parallel sliding of the shaft coupler in a parallel misalignment sliding hole (4), and then a parallel misalignment fixing nut (2) is used for fixing the position of the shaft coupler after adjustment so as to simulate parallel misalignment; the deflection angle misalignment control bolt (3) is screwed into the deflection angle misalignment control screw hole (7) to control the protrusion distance of the single-side coupler so as to simulate the deflection angle misalignment of the coupler. By simultaneously changing the sliding device and the penetrating bolt, the comprehensive misalignment of the coupler is simulated.

The invention has the advantages and effects that:

the test and the simulation experiment of this patent application in the misalignment of simulation shaft coupling can be carried out multiunit experimental measurement through the misalignment of simple operation adjustment shaft coupling and the form of misalignment under the condition of not dismantling the laboratory bench. The times of assembling and disassembling the experiment table are reduced, and the accuracy of the experiment result is improved; the coupler realizes stepless adjustment of the medium amount through the control of the penetration amount of the sliding mechanism and the bolt, and is more accurate and convenient compared with the traditional method of plugging a metal gasket.
