Problems solved by technology

Therefore, it is desirable that the load capacity of the thrust pads is reasonably evenly distributed during operation, which may be difficult in thrust bearings integrated in the main bearing, since, in the upward direction opposite to the removable upper part of the main bearing no thrust pads in the sector

Embodiment Construction

[0024] figure 1 Illustrated is an internal combustion engine 1 connected to a propeller shaft 3 with a propeller 4 through an intermediate shaft 2. The internal combustion engine may be a four-stroke engine or a two-stroke engine, such as the applicant's ME type or MC type two-stroke crosshead engine, and these engines are well known to those skilled in the art. The engine may have a cylinder diameter of 30 to 120 cm, and the number of cylinders may be, for example, 5 to 20. For a crosshead engine, the rotation speed may be 60 to 300 rpm. The output power of the engine may be 3000 to 130,000 kW, for example. The engine preferably has a relatively large output power, such as at least 30,000 kW, a cylinder number of at least 8, and a cylinder diameter of at least 70 cm.

Abstract

An internal combustion engine for driving a propeller shaft is composed of a rearmost main bearing of the internal combustion engine arranged between the throw of a crankshaft and a thrust cam inside a thrust bearing. A thrust segment(20) is arranged between a forward facing sliding face(22) on the thrust cam and a rearward facing supporting face(18) on a fixed type main bearing housing. Within a circumferential area, the thrust cam has a rotationally symmetric arc shaped recessed part(28) extending radially inward to the position of a height without exceeding an intermediate portion of the thrust segment (20).

Description

Technical field [0001] The present invention relates to an internal combustion engine used to drive a propeller shaft. At its rearmost main bearing, it has a thrust bearing. In the axial direction of the crankshaft, the main bearing is located on a crankshaft shaft and the thrust bearing The thrust cam can rotate together with the crankshaft, and the thrust bearing bush is arranged on the axially forward sliding surface of the thrust cam and the axial direction of the stationary bearing seat of the main bearing in the bottom plate of the internal combustion engine Between the back bearing surfaces. Background technique [0002] Integrating such a thrust bearing in the bottom plate of the main bearing at the rear end of the engine in an internal combustion engine will advantageously shorten the engine. Such internal combustion engines are generally the main engines of large ships. The large ship is, for example, a container ship. In this internal combustion engine, a very large to...
