Embodiment Construction

[0032] The centering device of the main engine and the gear box of the present invention will be further described in detail below in conjunction with the drawings and embodiments, in order to express the structural features and specific applications of the present invention more clearly, but it cannot be used to limit the scope of the present invention. protected range.

[0033] Please see first figure 1 , figure 1 It is a simplified diagram of the power plant layout of a certain type of ship. It can be seen from the figure that the main power plant is inclined downward from the propeller 11 to the gearbox 12, but the main engine 14 is installed horizontally, so an angle must be adopted between the two Make up the universal connector 13 of the device. After the position of the gearbox is determined, how to locate the main engine according to the position of the gearbox, so that the output of the main engine and the input end of the gearbox are on the same plane to avoid ben...

Abstract

The invention discloses a centring device of a main engine and a gear case. The centring device comprises a flange disc, a cylindrical sleeve and a centring needle tip, wherein one end of the cylindrical sleeve is fixedly connected with the flange disc, the circle center of the cylindrical sleeve is coaxial with that of the flange disc, a plurality of bolt holes are formed in the other end of the cylindrical sleeve, the outer diameter of one end of the centring needle tip is matched with the inner diameter of the cylindrical sleeve, the end of the centring needle tip extends into the cylindrical sleeve, passes through a bolt and is fixedly connected with the cylindrical sleeve through a bolt hole, the other end of the centring needle tip is of a needle tip type, a plurality of long oval through holes are formed in the flange disc, and the through holes are evenly distributed by taking the circle center as the center. The invention further discloses a method for manufacturing and using the centring device. The centring device is simple in structure, convenient to use and high in centring precision and has higher popularization value and use value.

Description

technical field [0001] The invention relates to the shipbuilding industry, in particular to a centering device for an output flange end of a main engine and an input flange end of a gearbox and a manufacturing and using method thereof. Background technique [0002] In the current design and construction of most ships, especially military ships, tugboats, passenger ships and other ships that have high requirements for maneuverability and speed, in order to obtain the best propulsion effect, the arrangement of the main power plant The outside often has an included angle with the horizontal, showing an oblique downward shape. The typical arrangement of these ship power plants generally includes these devices: propellers (adjustable pitch), several intermediate shafting systems, gearboxes, universal connectors, main engines, etc. [0003] The installation of these main power plant equipment is generally connected one by one according to the result of illumination positioning fr...
