Installation assembly for suspension vibration isolation device of integrated motor propeller

Abstract

The invention discloses an installation assembly for the suspension vibration isolation device of an integrated motor propeller, which comprises a propeller front guide pipe, a propeller middle guide pipe, a propeller rear guide pipe and an integrated motor stator and further comprises a suspension vibration isolation device. The integrated motor stator is arranged in a cavity defined by the propeller front guide pipe, the propeller middle guide pipe, the propeller rear guide pipe and the suspension vibration isolation device, the input end of the suspension vibration isolation device is fixedly connected with the integrated motor stator, and the output end of the suspension vibration isolation device is fixedly connected with the propeller front guide pipe or the propeller rear guide pipe. Electromagnetic vibration of the integrated motor is absorbed through pulling-pressing-bending-twisting comprehensive deformation of the suspension beam, and therefore transmission of vibration of the motor to a guide pipe is restrained; multiple suspension units are arranged between the isolated equipment and the installation foundation in the circumferential direction, and each suspension unit is provided with the multiple layers of suspension beams in the axial direction, so that the vibration suppression effect is improved, the inherent frequency of the vibration isolation system is adjusted, rigid support is provided for fixing of a motor, and the functions of supporting, vibration isolation, impact resistance and marine corrosion resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction of integrated motor propellers, and in particular relates to an installation assembly of a suspension vibration isolation device of an integrated motor propeller. Background technique [0002] In recent years, integrated motor propellers have become more and more widely used in military and civilian fields, in which the motor stator is integrated with the propeller duct, and the motor rotor is integrated with the propeller. The integrated motor propeller cancels the traditional propulsion shafting and the rotary seal of the penetrating shaft, which not only saves the space in the cabin, but also eliminates the coupling vibration of the propeller shaft system, which can provide convenience for the optimized layout of the cabin space and the control of vibration and noise. At the same time, after the propulsion motor is moved from the cabin to the outside, due to the ...

AI Technical Summary

Problems solved by technology

At the same time, after the propulsion motor is moved from the cabin to the outside, due to the influence of the installation space and the underwater working environment, the integrated motor cannot adopt traditional cabin vibration isolation measures to reduce electromagnetic vibration noise. Therefore, it is necessary to address such Integrated motor design a new type of vibration isolation structure that can adapt to the underwater working environment
