Description
Technical field
The present invention relates to a kind of diesel engine gear chamber structure, belong to engine and related system field, more particularly to a kind of
The special-shaped end plate of diesel engine rear gear chamber, it is particularly applicable to reduce manufacture difficulty, convenient for assembly, and for ease of maintenaince.
Background technique
Currently, being dropped since the operating fluctuation of diesel engine crankshaft-flywheel end is more stable relative to its front end for vibration damping
It makes an uproar consideration, gear chamber is arranged in engine cylinder body rear end by gear chamber postposition by more and more diesel engines, from crankshaft
Power needed for flywheel end output gear system.In the prior art, rear gear chamber is usually by the direct integral casting forming of cylinder body, or
Gear chamber is assembled to rear end of the cylinder block by person, finally installs the rear end gear chamber knot that bell housing forms complete closure
Structure, defect are as follows：
（1）, cylinder body and gear chamber integral casting forming structure：Casting technique difficulty is big, after cylinder body length dimension increase, tooling
It is increased with it with machining equipment, manufactures investment greatly, in addition, whole using grey iron casting, cylinder body weight is big, leads to complete machine weight
Amount increases therewith；
（2）, gear chamber the structure of rear end of the cylinder block is assembled to as individual part：Gear chamber corresponds to all gears, and bell housing is only born
Flywheel is blamed, the bulky of gear chamber is caused, and independent gear chamber is usually made by two kinds of materials --- gray iron or aluminium alloy,
Gray iron material disadvantage is that gear chamber weight is big, and aluminum alloy gear room disadvantage is to reduce engine rear end overall stiffness, in addition, gear
The huge feature of building volume will increase weight, rigidity in terms of defect, expand the difficulty of manufacture and assembly；
（3）, existing rear gear chamber the shortcomings that also reside in subsequent maintenance need to adjust between crankshaft and each system phase relation and
When gear backlash, it is necessary to just there are enough spaces to carry out gear adjustment after removing bell housing, and remove bell housing work on vehicle
Work amount is huge, along with also needing just to can be carried out transmission shaft, gearbox and flywheel while removing.
Application publication number is CN104989545A, and data of publication of application is that the application for a patent for invention on October 21st, 2015 discloses
A kind of diesel engine multi-functional housing for timing gear dual cycle cooling system, including housing for timing gear, the housing for timing gear
One side connect engine body, the engine body connect with cylinder cap, the cylinder cap connection systemic circulation outlet pipe, described
The cylinder cap left side connects partial circulating outlet pipe, and the housing for timing gear connects above-mentioned partial circulating outlet pipe；The housing for timing gear
Another side housing covef for timing gear is installed, the housing covef for timing gear connect with water pump.Although the design passes through thermostat
Control action is increased to the operating of cooling water, but it still has following defect：
Firstly, the medial surface of the housing for timing gear in the design covers all gray iron, it is bulky, meanwhile, timing gear
The lateral surface of engineer room is connect with housing covef for timing gear, causes housing for timing gear cover volume also huge, housing for timing gear, timing gears
The bulky defect of chamber cap generates more serious defect in terms of will lead to weight or rigidity, increases to manufacture, the assembly of product
It is difficult；
Secondly, the housing covef for timing gear in the design almost covers all gears, bell housing must be removed when easily leading to maintenance
Enough spaces could be provided, maintenance difficulty is increased；
Again, the medial surface of the housing for timing gear in the design is directly connected to gray iron, and bonding strength is weaker, whole rigid
It spends lower.
The information for disclosing the background technology part is merely intended to increase the understanding to the general background of present patent application, without
It should be considered as recognizing or implying in any form that the information constitutes existing skill already known to those of ordinary skill in the art
Art.

Point is as follows：Firstly, extending engine rear end face, gear train installation space ensure that；Secondly, to the shape of rear end plate body with
And the position in each hole has all carried out special design, to be defined to the shape of housing covef for timing gear, bell housing, makes
It obtains most gear to be covered by bell housing, rather than is covered by housing covef for timing gear, thereby reduce housing for timing gear
The volume of lid is also conducive to improve housing covef for timing gear, bell housing convenient for reducing the manufacture difficulty and cost of housing covef for timing gear
Assembly efficiency；Again, special-shaped end plate is defined the binding site and combination of housing covef for timing gear, bell housing,
So that in maintenance, only it need to open housing covef for timing gear and can have enough spaces and repair or adjust gear timing and side
Gap, operation is very convenient, does not need disassembly bell housing.Therefore, not only manufacture difficulty is smaller, cost is relatively low, Er Qierong by the present invention
Easily assembly, maintenance difficulty are lower.
2, in a kind of special-shaped end plate of diesel engine rear gear chamber of the present invention, housing covef for timing gear, bell housing by
It is connected in special-shaped end plate with engine cylinder block, cylinder cap, rather than is directly connected with engine cylinder block, cylinder cap,
Advantage is as follows：Firstly, the addition of special-shaped end plate, increases additional rigid material, conducive to the entirety for promoting engine rear end
Rigidity, especially when the manufacture material of special-shaped end plate is high-strength steel sheet, rigidity is stronger；Secondly, in special-shaped end plate conduct
Jie's bridge, cylinder block/cylinder cap is tighter, stronger in conjunction with gear chamber/bell housing so that cylinder block, cylinder cap, gear chamber,
Bell housing is more towards for an entirety, to possess stronger rigidity and the consistency that cooperates.Therefore, rigidity of the invention is stronger,
The consistency that cooperates is preferable.
3, in a kind of special-shaped end plate of diesel engine rear gear chamber of the present invention, be provided on the plate body of rear end various holes with
And bottom vacancy mouth, L-type notch, the design not only for installation gear train, and to housing covef for timing gear, bell housing it is each
It is influenced and is limited from shape, combination, and the weight of rear end plate body can also be reduced, to reduce the whole of rear gear chamber
Body weight.Therefore, lighter in weight of the invention.
