Problems solved by technology

[0006] However, if the strength of the slide plate is increased to suppress the deformation of the slide plate, the cost will increase, the surface pressure between the slide plate and the crosshead will increase, and the oil film of the lubricating oil may disappear.

Embodiment Construction

[0055] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0056] figure 1 A schematic diagram showing a crosshead diesel engine according to an embodiment of the present invention. The diesel engine shown in the figure is mainly used as the main engine for ship propulsion, and adopts the direct-current scavenging method of two-stroke and one working cycle.

[0057] This diesel engine has a frame 20 located below, a frame (main body) 5 provided on the frame 20 , and a cylinder liner 21 provided on the frame 5 . The machine base 20, the machine frame 5, and the cylinder liner 21 are integrally fastened and fixed by a plurality of tension bolts (not shown) extending in the vertical direction.

[0058] A cylinder liner 22 is provided on the cylinder liner 21 , and a cylinder head 23 is provided at an upper end of the cylinder liner 22 . A reciprocating piston 1 is provided in a space formed by the cylinder liner 22 and the cy...

Abstract

A cross head for a cross head type diesel engine, provided with: a pin (14) for pivotably connecting one end of a piston rod and one end of a connecting rod; shoes (8) reciprocating while sliding relative to slide plates (6) raised from the affixed ends thereof, which are affixed to a framework, toward the free ends (6b) thereof; and connecting plates (13) for connecting the pin (14) and the shoes (8). The axis (C1) of each of the arm section (13a) of each of the connecting plates is offset to the inner end section (8b) side from the center of the corresponding shoe (8).

Description

technical field [0001] The invention relates to a crosshead of a crosshead diesel engine. Background technique [0002] Conventionally, a crosshead type diesel engine has been used as a main engine for ship propulsion (see Patent Document 1). Such a crosshead type diesel engine has a crosshead that rotatably connects one end of a piston rod and one end of a connecting rod, and slides and reciprocates on a slide plate fixed to a main body side. As the crosshead reciprocates on the sliding plate, force is transmitted from the piston to the crosshead through the piston rod. The component force of the transmitted force in the lateral direction (direction toward the slide plate) is called a lateral force, and is a force that deforms the slide plate. [0003] In order to suppress the deformation of the sliding plate, conventionally, the strength of the sliding plate has been increased by increasing the thickness of the sliding plate or providing additional ribs for suppressing t...
