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 There is illustrated an internal combustion engine 1 connected via an intermediate shaft 2 to a propeller shaft 3 with a propeller 4 . The internal combustion engine may be a four-stroke engine or a two-stroke engine, such as the applicant's ME or MC two-stroke crosshead engine, which are known to those skilled in the art. The engine may have a bore of 30 to 120 cm, the number of cylinders may be 5 to 20, and for a crosshead engine, the rotational speed may be 60 to 300 rpm. The output power of the engine can be, for example, 3000 to 130000 kW. The engine preferably has a relatively large output power, such as at least 30,000 kW, with at least 8 cylinders and a bore of at least 70 cm.

[0025] In the rearmost main bearing 5 of the crankshaft 6, the internal combustion engine 1 has a figure 2 The rear view of the thrust bearing 7, the longitudinal section of the thrust bearing is shown in Figure 3. The fixed bearing seat of the main bearing 5 is cast in one...

Abstract

The rearmost main bearing of the internal combustion engine is arranged between a crankshaft shaft and a thrust cam of a thrust bearing. A thrust pad (20) is disposed between the axially forward sliding surface (22) of the thrust cam and the axially rearward bearing surface (18) of the stationary main bearing housing. The thrust cam (14) has a rotationally symmetrical arc-shaped groove (28) in a peripheral area, which groove extends radially inwards at most to the middle position of the thrust bearing bush (20).

Description

technical field [0001] The invention relates to an internal combustion engine for driving a propeller shaft, which has, at its rearmost main bearing, a thrust bearing, in the axial direction of the crankshaft, said main bearing being located between a shaft shank of a crankshaft and said thrust bearing Between the thrust cam (thrust cam), which can rotate together with the crankshaft, the thrust bearing bush is arranged on the axial 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 rear bearing surfaces. Background technique [0002] Integrating such a thrust bearing in an internal combustion engine in the base plate of the rearmost main bearing of the engine advantageously makes the engine shorter. This internal combustion engine is generally the main engine of large ships. The large ship is, for example, a container ship. In such internal ...
