Abstract

The invention relates to a unit vibration isolation system, in particular to a vibration isolation system of a marine main streamer gear unit to solve the problems that an existing main steamer gear unit is high in machine leg vibration acceleration and poor in shock resistance capability of a main unit. The single-layer vibration isolation system is arranged between a main unit and a ship base, and comprises sixty-two conical vibration isolators and eighteen cylindrical vibration isolators. Eighteen conical vibration isolators are arranged below a beam of a main steamer unit of the main unit, the left side and the right side of the beam of the main steamer unit of the main unit are respectively provided with two cylindrical vibration isolators, forty-four conical vibration isolators are arranged below a main speed reducing gear device of the main unit, and the left side and the right side of the main speed reducing gear device of the main unit are respectively provided with seven cylindrical vibration isolators. The vibration isolation system is used for isolating vibration of the marine main steamer gear unit.

Description

Technical field [0001] The invention relates to a vibration isolation system for a unit, in particular to a vibration isolation system for a marine main steam turbine gear unit, and belongs to the technical field of ship power steam turbine vibration isolation. Background technique [0002] The vibration transmission of the main steam turbine gear unit plays a decisive role in the stealth performance of the ship. The previous ship’s main steam turbine gear units are rigid installation units. The operating environment of the marine steam turbine gear units is completely different from that of the land-based units. Rolling, pitching and possible shock environment specific to marine crew. At present, there is no basis and experience in the installation and alignment of the corresponding flexible support host group. The existing main steam turbine gear unit has high vibration acceleration and poor shock resistance of the main unit. Summary of the invention [0003] The present inven...
