Embodiment Construction
[0019] The present invention will be described in more detail below in conjunction with the accompanying drawings:
[0020] combine Figure 1-4 , The present invention is an impact vibration isolator for transmission equipment based on foam aluminum crushing. The present invention consists of a vibration isolation part and an anti-shock part, and relies on a spring and a damping rubber pad to form a spring damping system to isolate the vibration generated by the operation of the equipment. When a severe impact is received, the strong impact generated by the limit device of the vibration isolator acts on the energy-absorbing box, and the energy-absorbing box will be crushed and deformed to absorb the impact energy to protect the safe operation of the equipment. When there are only vibration loads and impact energy When it is small, the energy-absorbing box will be elastically deformed, which can ensure the normal operation of the equipment.

The purpose of the present invention is to provide an impact vibration isolator for transmission equipment based on foam aluminum crushing, including a piston rod, a sealing cover, a vibration isolator base, and a base. The vibration isolator base is fixed on the base through mounting bolts, and the sealing The cover is fixed on the base of the vibration isolator by connecting bolts. The base of the vibration isolator is provided with a piston structure that protrudes upward. The end of the piston rod extends into the sealing cover and is located inside the piston structure to match the piston structure. The end of the piston rod An energy absorbing material is arranged between the base of the vibration isolator at the bottom of the piston structure and the plane of the base of the vibration isolator. In the present invention, a spring and a damping gasket are used to form a spring vibration isolation system. When subjected to a vibration load, the spring damper is mainly used to weaken and dampen the vibration generated by the operation of the equipment; the spring damper has a limited function, which can ensure the vibration isolation. At the same time, it will not produce much displacement to ensure the normal operation of the equipment. When being impacted, the impact energy is absorbed by a combination of air cavity and foamed aluminum to ensure the normal operation of the equipment.
Description
technical field [0001] The present invention relates to an anti-shock device, in particular to a shock isolator. Background technique [0002] With the increasingly stringent evaluation requirements of modern ship equipment, during the service of ships at sea, marine equipment is required not only to have strong operating capabilities, but also to have strong impact resistance capabilities. The vibration isolators used in the existing ship equipment mainly focus on vibration isolation, and most of them have limited position. According to research, the position limit will cause the equipment to be subjected to secondary shocks. Therefore, it is necessary to strengthen the anti-vibration of the equipment on the basis of considering the vibration isolation of the equipment. punching ability. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an impact vibration isolator for transmission equipment based on foam aluminum crushing, which can ac...
