Embodiment Construction

[0014] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0015] Such as Figure 1 to Figure 5 As shown, a power unit group that can be integrally disassembled on a diesel engine includes a cylinder head 4, a cylinder liner 3, a piston 2, a connecting rod 1 and a power block 5, and the top of the cylinder liner 3 is connected to the cylinder head 4 through bolts. The bottom of the cylinder liner 3 corresponds to the piston 2 and the connecting rod 1 and is bolted to the power block 5, and the power block 5 has a screw for limiting the degree of freedom of the connecting rod 1 and a fine-tuning screw for adjusting the upper and lower positions of the piston 2.

[0016] see Figure 5 , there is a water passing ring 10 on the cylinder liner 3, and 4 bolt holes are provided on the top surface of the water passing ring 10, and 4 hexagon socket long bolts 11 are used to penetrate from the top of the cylinder h...

Abstract

The invention discloses an integrally-detachable power unit on a diesel engine. The integrally-detachable power unit comprises an air cylinder cover, an air cylinder sleeve, a piston and a connecting rod, and the integrally-detachable power unit is characterized by also comprising a power unit stop block, the top of the air cylinder sleeve is connected with the air cylinder cover through a bolt, the bottom, corresponding to the piston and the connecting rod, of the air cylinder sleeve is connected with the power unit stop block through a bolt, the power unit stop block is provided with a screw for limiting the degree of freedom of the connecting rod, and a micro-tuning screw for adjusting the vertical position of the piston. The integrally-detachable power unit is simple in structure and reasonable in design, and the integral disassembling and installation of the air cylinder cover, the air cylinder sleeve, the piston and the connecting rod and the independently disassembling of each part can be realized; the power unit stop block can be conveniently disassembled and installed; when a large end of the connecting rod is installed onto a crankshaft, a fault tolerance and micro-tuning function can be realized; the modularized assembling of the diesel engine is realized, and the integrally-detachable power unit is widely applied to a diesel engine with the power of 2000KW to 3500KW for railway locomotives and ships.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, in particular to a power unit group on a diesel engine. Background technique [0002] At present, during the maintenance of domestic 2000KW~3500KW high-power diesel engines, the cylinder head, cylinder liner, piston and connecting rod are all independent units.
