Embodiment Construction

[0016] The embodiments of the present invention will now be described in conjunction with the accompanying drawings, and the present invention is not limited to the following embodiments.

[0017] Such as figure 1 As shown, a vibration-absorbing and vibration-isolating integrated device includes a vibration isolator 1, a cantilever rod 2, an adjustable pressure block and a spring. The two ends of the cantilever rod are respectively provided with external threads, and the bottom end is screwed to the vibration isolator, and The positioning nut 3 is fastened and screwed to replace the original vibration isolator and the fastener of the equipment machine foot, reducing the external interface of auxiliary equipment and improving space utilization. The top of the cantilever rod is screwed with the lock nut 4 to adjust the pressure The block is sleeved in the middle of the cantilever rod, and can slide up and down along the cantilever rod, and is limited by the upper elastic element...

Abstract

The invention relates to a vibration absorption and insulation integrated device comprising a vibration insulator, a cantilever rod, an adjustable pressing block and a spring. The two ends of the cantilever rod are provided with outer threads correspondingly, the bottom of the cantilever rod and the vibration insulator are connected in a threaded mode and fastened through a positioning nut, and the top end of the cantilever rod is in threaded connection with a locking nut. The middle of the cantilever rod is sleeved with the adjustable pressing block, the adjustable pressing block slides vertically along the cantilever rod, and the device further comprises an upper elastic element and a lower elastic element which are symmetrically arranged on the cantilever rod corresponding to the adjustable pressing block in a sleeving mode. Through integrated design of the vibration insulator and a power vibration absorption device, connection between an auxiliary machine and the vibration absorption and insulation device can be simplified, and the spatial utilization rate can also be sufficiently increased.

Description

technical field [0001] The invention belongs to the technical field of ship vibration reduction and noise reduction, and in particular relates to a vibration absorption and vibration isolation integrated device. Background technique [0002] In order to reduce the low-frequency line spectrum characteristics of auxiliary equipment, in addition to vibration isolation, auxiliary equipment usually needs to absorb vibration at a specific frequency to reduce the peak value at the fundamental frequency of auxiliary equipment. Vibration isolation is achieved through a vibration isolator (or vibration isolation device), and vibration absorption at a specific frequency needs to be achieved through a dynamic vibration absorber. If the vibration isolator and dynamic vibration absorber are arranged separately near the foot of the auxiliary machine, not only the interface is complicated, but also the space is occupied. Contents of the invention [0003] The purpose of the present inven...
