Description
Technical field
The utility model relates to bell housing technical field, in particular to a kind of bell housing of postposition train engine.
Background technique
The carrier that bell housing effectively couples as engine with gearbox, carry external crankcase, starter, oil sump,
Built-in fly wheel assembly plays the role of coupling body protection and carrier, also acts as and undertakes gearbox weight and power transmitting fulcrum
Effect, due to bell housing be chronically at weight and work external force under the conditions of, inevitably have a degree of abrasion and deformation, fly
The wheel shell depth of parallelism, bearing saddle bore centrad misalignment after deformation just will affect the transmitting of output power, generate transmission abnormal sound；Separately
Outer bell housing, which also needs to have good heat sinking function, could effectively guarantee the normal operation of body, and the flywheel shell structure of finished product is special
Point and outer dimension, it is necessary to adapt to engine and the mating characteristic of gear-box and size and the airtightness of connection.
To sum up: while researching and developing bell housing and engine mating feature, how to improve bell housing carrying machine weight,
It improves power and transmits fulcrum, the heat dissipation effect for reducing abrasion and shell becomes particularly important.
Summary of the invention
The purpose of this utility model: in order to realize the matching with certain engine, while improving the rigidity of bell housing ontology,
Reduce abrasion deformation, ensure that the output of power, reduces transmission abnormal sound, the flywheel of one of design postposition train engine
Shell.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of postposition train flywheel shell of engine includes:
The surface distribution of bell housing ontology, and the gear-box being arranged on bell housing ontology, the bell housing ontology is set
Several surface reinforcing ribs are equipped with, the side of the bell housing ontology, which is distributed, is provided with several side reinforcing ribs, in the gear-box
Portion is equipped with first bearing bearing block, second bearing seat, 3rd bearing seat and fourth bearing seat；
Crankshaft input hole, the crankshaft input hole run through above-mentioned bell housing ontology and gear-box；
Starter connecting flange, the starter connecting flange are mounted on gear box side shell；
As an improvement: bell housing ontology side and the side of gear-box are equipped with several bolts hole.
As an improvement: the shape of the gear-box is V-type.
As an improvement: the first bearing seat and 3rd bearing seat are symmetricly set on described relative to crankshaft input hole
Inside gear-box.
As an improvement: the second bearing seat and fourth bearing seat are symmetricly set on described relative to crankshaft input hole
Inside gear-box.
The positive beneficial effect that the utility model generates:
1. realizing the matching with certain engine；
2. improving the rigidity of bell housing ontology, and then reduce abrasion deformation；
3. ensure that the good output of power, reduce transmission abnormal sound.

Specific embodiment
Specific embodiment of the present utility model is illustrated with reference to the accompanying drawing.
In the present embodiment, a kind of postposition train flywheel shell of engine, comprising: bell housing ontology, and be arranged in flywheel
The surface distribution of gear-box on shell ontology, bell housing ontology is provided with several surface reinforcing ribs, bell housing ontology side and tooth
The side of roller box is equipped with several bolts hole, if the side distribution of bell housing ontology is provided with dry side reinforcing rib, the shape of gear-box
Shape is V-type, is equipped with first bearing seat, second bearing seat, 3rd bearing seat and fourth bearing seat, first bearing seat inside gear-box
It is symmetricly set on inside the gear-box with 3rd bearing seat relative to crankshaft input hole, second bearing seat and fourth bearing seat phase
Crankshaft input hole is symmetricly set on inside the gear-box.
Crankshaft input hole, the crankshaft input hole run through above-mentioned bell housing ontology and gear-box.
Starter connecting flange, the starter connecting flange are mounted on gear box side shell.
Several reinforcing ribs are respectively provided on the surface of bell housing ontology and side, ensure that the original depth of parallelism of bell housing and song
The accuracy of axis input hole centrad reduces unnecessary abrasion, and then decreases the abrasion of secondary part parts, bearing
Seat is symmetricly set in gear-box relative to crankshaft input hole, be ensure that the compactness of bearing block, is reduced transmission abnormal sound.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of the utility model rather than limit it
System；Although the utility model has been described in detail with reference to the preferred embodiment, those of ordinary skill in the art should
Understand；Specific implementation of the utility model can still be modified or is equally replaced to some technical characteristics
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
