Problems solved by technology

However, the use of rigid gaskets makes the vibration of the main engine completely borne by the hull base, resulting in a large vibration amplitude around the main engine, which will affect the vibration control of the superstructure living area and even the whole ship in severe cases, and the ship is very noisy

Embodiment Construction

[0020] The specific application of the host installation method with elastic support will be further described below in conjunction with the drawings and specific embodiments, but the protection scope of the present invention should not be limited by this.

[0021] The following takes a high-tech product as an example to describe in detail a host installation method with elastic damping block and elastic support of the present invention, such as figure 1 As shown in Figure 2, the mainframe includes a mainframe base 1 and a mainframe base 2. The mainframe base and the mainframe base are connected by an elastic support 3. The elastic support includes a vertical shock-absorbing block 31 and a lateral The shock-absorbing block 32 and the longitudinal shock-absorbing block 33 include the following installation steps:

[0022] 1. According to the results of shaft alignment, use temporary supports to determine the installation position of the gearbox and the host

[0023] The main engin...

Abstract

The invention discloses an installation method of a main engine with an elastic support, the main engine comprises a main engine carrier block and a main engine base, the main engine carrier block is connected with the main engine base through the elastic support, and the elastic support comprises a vertical shock absorbing block, a side shock absorbing block and a longitudinal shock absorbing block. The elastic support is arranged between the main engine carrier block and the base, and the vibration generated during the operation of the main engine is absorbed by a rubber damping device of the rubber shock absorbing block, so that the vibration and the noise are weakened. The use of the installation method can shorten the overall installation period of the ship main engine and greatly enhance the progress. The method is applicable to ships with higher requirements on the ship noise and the vibration indicators, so as to obtain good working and living environment of the ships and the comfort of passengers.

Description

Technical field [0001] The invention belongs to the technical field of ship construction, and particularly relates to a method for installing a main engine with elastic support. Background technique [0002] The main engine is the heart of the ship's propulsion system, and its reasonable installation is closely related to the overall propulsion efficiency of the ship, the control of vibration and noise, and the ship construction cycle. [0003] In my country, steel gaskets or epoxy gaskets are usually used for host installation. After the hull is built to meet the baseline and can be determined, the base of the main engine is positioned and welded according to the results of the cable lighting. After launching, the main engine is positioned according to the reasonable shafting process, and then steel gaskets or cast epoxy are applied according to the relative position of the base and the hull. The gasket is finally installed and positioned with the anchor bolts, thrusters and top...
