Abstract
The utility model discloses a kind of diesel engine crankcase attachment structure, belong to Diesel Engine Technique Field.Its technical scheme is：Including crankcase and oil sump, rebound is set, rebound includes body, and body is up and down plane, and upper plane is connected with crankcase bottom surface, the upper surface connection of lower plane and oil sump between crankcase and oil sump.The beneficial effects of the utility model are：Reasonable in design, simple in construction, the mach precision of aluminium casting is higher so that peripheral components（Including booster, gs-oil separator etc.）Oil return pipe installation it is more accurate, reduce oil leak risk；Overall construction intensity is good, can ensure the flatness of mounting surface well, meet engine sealing requirements；The extension of appearance and size so that the mounting plane of oil sump is not limited to crankcase bottom surface, and a kind of scheme is provided to increase the volume of oil sump.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, and in particular to a kind of diesel engine crankcase attachment structure.
Background technology
General crankshaft of diesel engine lower box part is directly connected to oil sump, and some nipples are welded with oil sump and are used to connect
Peripheral components（Including booster, gs-oil separator etc.）Oil return pipe, and oil gauge pipe connecting tube.Because of welding procedure itself
Limitation, the positional precision of these back leakage connections is relatively low, once back leakage connection snaps, is broken, can produce oil leakage phenomenon, seriously can also
Cause dieselization watt.
Utility model content
To solve the deficiency of above-mentioned prior art, the purpose of this utility model is to provide a kind of diesel engine crankcase connection knot
Structure.
A kind of diesel engine crankcase attachment structure, including crankcase 9 and oil sump 8, the crankcase 9 and oil sump 8 it
Between rebound is set, the rebound includes body 1, and body is plane about 1, and upper plane and the bottom surface of crankcase 9 connect
Connect, lower plane is connected with the upper surface of the oil sump 8；
The middle part hollow out of body 1, its openwork part area are more than activity space required during crankshaft mobility to rebound；
The lower plane periphery of body 1 is horizontally disposed with surrounding edge 10, and some screwed holes, oil return pipe of supercharger are set on surrounding edge 10
7 connection screw thread holes 1, the connection screw thread hole 23 of Oil-gas Separation oil return pipe 6, oil gauge pipe are passed by screwed hole 34, machine oil liquid level
Sensor connection screw thread hole 45；The area of surrounding edge 10 is corresponding with the upper surface of the oil sump 8；The top edge fitting of oil sump 8
The lower surface of surrounding edge 10.
Preferably, the surrounding edge 10 is arranged on the bottom of the body 1, between surrounding edge 10 and 1 side wall of the body
It is distributed reinforcement.
Preferably, the openwork part of the body 1, across setting some reinforcements between its madial wall.
Preferably, the body 1 is process by aluminium casting blank.
Preferably, this diesel engine crankcase attachment structure is applied to MC07 engines.
By experiment, the beneficial effects of the utility model are, reasonable in design, simple in construction, the mach precision of aluminium casting
It is higher so that peripheral components（Including booster, gs-oil separator etc.）Oil return pipe installation it is more accurate, reduce oil leak wind
Danger；Overall construction intensity is good, can ensure the flatness of mounting surface well, meet engine sealing requirements；Appearance and size
Extension so that the mounting plane of oil sump is not limited to crankcase bottom surface, and a kind of scheme is provided to increase the volume of oil sump.

Connect, lower plane is connected with the upper surface of oil sump 8；
The middle part hollow out of body 1, its openwork part area are more than activity space required during crankshaft mobility to rebound；
The lower plane periphery of body 1 is horizontally disposed with surrounding edge 10, sets some screwed holes on surrounding edge 10, oil return pipe of supercharger 7 connects
Screwed hole 1, the connection screw thread hole 23 of Oil-gas Separation oil return pipe 6 are connect, oil gauge pipe passes through screwed hole 34, engine oil liquid level sensor
Connection screw thread hole 45；The area of surrounding edge 10 is corresponding with the upper surface of oil sump 8；The top edge fitting surrounding edge 10 of oil sump 8
Lower surface.
Surrounding edge 10 is arranged on the bottom of body 1, is distributed reinforcement between surrounding edge 10 and the side wall of body 1.
The openwork part of body 1, across setting some reinforcements between its madial wall.
Body 1 is process by aluminium casting blank.
This diesel engine crankcase attachment structure is applied to MC07 engines.
Technical characteristic of the utility model without description can be realized by or using prior art, will not be repeated here,
Certainly, described above is not to limitation of the present utility model, and the utility model is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the those of ordinary skill in domain is made in essential scope of the present utility model, it should also belong to
The scope of protection of the utility model.
