Problems solved by technology

This leads to high stresses in the housing and deformation of the bearing shell, since the tie rod has to be fixed under the housing under great pretension
Therefore, from a purely structural point of view, the known substrate is relatively hard and relatively complex

Embodiment Construction

[0021] The crosshead large diesel engine according to the invention, designated hereinafter as a whole by the reference numeral 1, is designed in particular as a two-stroke large diesel engine 1 with longitudinal scavenging, which is widely used, for example, in ships.

[0022] figure 1 A known form of a crosshead large diesel engine 1 is schematically shown in section, having a base plate 2 , a stator 5 and a cylinder part 10 . The cylinder section 10 is used in a known manner to receive cylinders, not shown. The stator 5, which has been formed, for example, by welding steel sheets together, has a sheet metal base plate 15 and two outer walls 4 and together with sliding surfaces 8 extending vertically according to the figures form two frames, which are conical in cross-section They are connected to each other by a common sheet metal top plate 16 . The two vertically extending opposite sliding surfaces 8 are supported by a central wall 17 arranged between the two conical fra...

Abstract

A crosshead large diesel engine is proposed, comprising a base plate (2) for receiving a crankshaft (3) and a stator (5) comprising two outer walls (4) and arranged on the base plate (2). The stator (5) comprises at least one support body (6) of double-walled form through the use of transverse support walls (7) and having sliding surfaces (8) for two adjacent crossheads (9). A cylinder part (10) is arranged on the stator (5) for receiving the cylinder, the base plate (2), the stator (5) and the cylinder part (10) are connected to each other by at least one tie rod (11) ) extends in the region of the double-wall support (6), a transverse support element (12) is arranged in the base plate (2) and is in the form of a single wall.

Description

technical field [0001] The invention relates to a crosshead large diesel engine comprising a base plate for receiving a crankshaft; a stator comprising two outer walls, arranged on the base plate and comprising at least one support body, which is supported by the use of transverse support walls is in the form of a double wall and has sliding surfaces for two adjacent crossheads; and a cylinder part arranged on the stator for receiving the cylinder, the base plate, the stator and the cylinder part being connected to each other by at least one tie rod, the The tie rods extend in the region of the stator within the double-wall support body. Background technique [0002] Large diesel engines in the form of crossheads are preferably used in ships or, for example, in stationary power plants for the generation of electrical energy, which comprise three large housing sections which form the frame of the engine. A so-called stator is arranged on a base plate which, in addition to be...
