Embodiment Construction

[0049] The large-scale crosshead diesel engine according to the invention, indicated generally by the reference numeral 1 hereinafter, is manufactured in particular as a two-stroke large-scale diesel engine with once-through scavenging, eg widely used in shipbuilding.

[0050] In the further description, reference will be made to figure 2 and image 3 The design of a known large crosshead diesel engine from the prior art is discussed for purposes of illustration and description of the present invention. In the description of the prior art that differs from the present invention, those features relating to engines known from the prior art are provided with an apostrophe, whereas features according to the present invention are denoted by reference numerals without an apostrophe.

[0051] figure 1 The general design of a large crosshead diesel engine 1 , 1 ′ is shown schematically in cross-section, for example already known in the prior art, but can in principle also be imple...

Abstract

The present invention relates to a large crosshead diesel engine, including a base for receiving a crankshaft and a rack having two outer walls, the rack is arranged on the base and includes at least one support body, and the support body is designed to have two walls through lateral bracing walls and includes a sliding surface for two neighboring crossheads. A cylinder part is arranged on the rack for receiving a cylinder, the base, the rack and the cylinder part are connected with one another through at least one connecting rod extending in the dual-wall support body in the region of the rack. The base is provided with a single-wall lateral bracing element, and includes at least one bearing seat for mounting a shaft collar of the crankshaft. According to the invention, by means of a holding element capable of removing from a cut, the connecting rod is fixed in the cut in the bearing seat arranged in a region between a longitudinal axis (K) of the crankshaft and the lower end of the base far from the rack.

Description

technical field [0001] The present invention relates to a large crosshead diesel engine according to the preamble of independent claim 1 . Background technique [0002] A large diesel engine of crosshead configuration, preferably for use in shipbuilding or in stationary installations (eg for power generation), comprises three large hull segments which form an engine frame. A so-called pedestal is arranged, separated by a base, on which the pedestal has transverse support elements next to the bearing seats, with crankshaft main bearings for the journals of the crankshaft. The gantry includes a number of supports corresponding to the number of cylinders of a large diesel engine, each support body having a sliding surface extending in a vertical manner for the guidance of two adjacent crossheads, which are driven by pushing The rod is connected to the crankshaft. In this connection, the two corresponding sliding surfaces, which are arranged towards each other and extend in a ...
