Description
Technical field
The utility model belongs to diesel engine mounting technique field, and in particular to a kind of large-power marine diesel engines support branch
Hold.
Background technology
Diesel engine base supporting refers to coupling part between diesel engine under-chassis and hull pedestal, according to supporting transmission power and
The characteristic of its deformation, can be divided into non-yielding prop and the major class of elastic bearing two, and non-yielding prop is mainly used in most of civilian transport
Ship, elastic bearing is mainly used in the ship for civil use and military boats and ships for requiring to reduce vibration.The effect of supporting is mainly bavin
Oil machine is fixed on hull, and carries the weight of whole diesel engine, is born from various dynamic on diesel engine under-chassis and pedestal
Dead load, it is ensured that the stabilization of fixed position and body of the diesel engine under various operational configurations, is carried out to vibration, impact, noise
Isolation, to ensure the normal work of diesel engine, improves surrounding environment.
It is because branch withstands forces sufficiently complex, fluctuation that such as inertia force, power of toppling and wave cause external force therefore existing
Be supported in actual design and generally can not comprehensively consider that these influence, it is impossible to it is high to meet intensity, rigidity while very well, installs
It is convenient, it is lightweight, the characteristics of good stability.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of large-power marine diesel engines support supporting,
The supporting structure is compact, connection and reasonable arrangement, rigidity, intensity reliability；Low cost of manufacture.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions：
A kind of large-power marine diesel engines support supporting, including hull mounting surface 2 and body mounting surface 1, the hull peace
Dress face 2 is fixed on hull, and the body mounting surface 1 is connected using bolt 3 with diesel-engine body, by main spindle hole shelves
It is one group of connection to use three bolts between the body mounting surface 1 of number, every grade of diesel-engine body side and support supporting, and often
Group bolt is triangularly arranged.The triangular arrangement of bolt can increase the anti-shearing torque of bolt.
In order to consistent with diesel-engine body flank angle, two angle angles of mounting surface are supported according to Design Technology for Diesels support
Degree.In one embodiment of the present utility model, the hull mounting surface 2 and body mounting surface 1 are mutually 80 ° of angles.
Design of length of the quantity of bolt 3 according to diesel-engine body.Preferably, the supporting of each support is using 7 groups totally 21
The high-strength bolt 3 of M24 is connected with body.
Preferably, being provided with the middle of the triangle of the formation of the bolt 3, body is horizontal to draw bolt to avoid hole 4.The design be for
Avoidance body horizontal drawing bolt.
Preferably, the every file location in support supporting correspondence main spindle hole gear number designs two reinforcement gussets 5, often
It is connected with each other using reinforcement gusset 5 between 3 bolts of group, so increases the rigidity of support supporting.
Used as preferred technical scheme, body mounting surface 1 is designed with multiple semi-circular structures 6.At one of the present utility model
In embodiment, the semi-circular structure 6 has 5.On the one hand the design of semi-circular structure observes cover plate to avoid diesel engine crankcase,
On the other hand the weight of support supporting is alleviated.
Used as preferred technical scheme, on the body mounting surface 1, the position that bolt 3 is connected with diesel-engine body sets
Locating surface 7 is counted into, and locating surface is not made at remaining position.Locating surface is the plane for being used to determine position as datum clamp face.By
Supported in support it is very long, with the flatness of body binding face in processing it is difficult to ensure that, therefore, bolt connection position is designed to
Locating surface is not made at locating surface, remaining position, can so reduce difficulty of processing, while alleviating the weight of support supporting, saves
Manufacturing cost.
As preferred technical scheme, be disposed with the body mounting surface 1 of supporting not through alignment pin 8.In this practicality
In new one embodiment, the alignment pin 8 has 6.
In order to avoid diesel engine and hull under any state between produce relative movement, every pretightning force of connecting bolt
It is 450Nm.
Used as further preferred technical scheme, the alignment pin 8 is arranged between two reinforcement gussets 5.
Every diesel engine respectively installs a support supporting described in the utility model, support supporting in the left and right side of body
Locating surface on body mounting surface is closely affixed with body side, and each locating surface is by 3 one group and is triangularly arranged
It is bolted on the side of diesel-engine body, by strengthening link of boards between every group of bolt, forms firm overall, hull
Mounting surface is fixed on hull.Diesel engine base support stiffness of the present utility model, intensity are high, good stability, light weight, save
Cost.
