Description
Technical field
The utility model is related to gear-box technical field, especially a kind of high-performance large-scale welded-type gear box structure.
Background technology
Currently, existing welded gear case uses forging beam welding structure, due to the cross in existing welded gear case
The size of beam exceeds existing plank specification, the i.e. not no plank of required thickness, can only select forging adding as crossbeam
Work blank.Due to bearing area and oil sealing area one, boring oil-recovery tank is also needed while boring oil-feed tank and bores oil return hole.In this way
Just be added significantly to boring, brill process, extend the production cycle.Therefore the shortcoming of original gear-box is embodied in following
Problem：Forging is of high cost, and bore hole is more, long in time limit；Since the welding technique of former babinet is immature, so to improve babinet
Material is selected as 16Mn by rigidity and weldability, and 16Mn is expensive；Due to original gear box body, crossbeam is thicker, is welded with thin plate
It connects, thin plate is often drawn to deform huge；Shape is unsightly；Due to being the structure of crossbeam, each babinet consistency is bad, design
Disunity.Increase design, the probability of manufacture error.
Therefore, for the above problem, it is necessary to propose a kind of high-performance large-scale welded-type gear box structure.
Utility model content
The utility model aim is to overcome deficiency in the prior art, provides a kind of high-performance large-scale welded-type gear
Box structure.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of high-performance large-scale welded-type gear box structure, including procapsid, middle casing, back casing, top panel and below
Plate, the procapsid are connect by the first bolt with middle casing, and the middle casing is connect by the second bolt with back casing, described
The lower end of procapsid, middle casing and back casing is welded on the upper surface of lower panel, the procapsid, middle casing and back casing
Upper end be welded on the lower face of top panel, the front end face of the procapsid is provided with first through hole, the back casing
Rear end face is provided with the second through-hole, and the right edge of the middle casing is provided with third through-hole.
Preferably, the first through hole has been bolted the first connecting flange by third, and second through-hole passes through
Four the second connecting flanges of bolt.
Preferably, the third through-hole has been bolted third connecting flange by the 5th.
Preferably, the procapsid is provided with several the first bolts hole being spaced apart with middle casing junction, described
Back casing is provided with several the second bolts hole being spaced apart with middle casing junction.
Preferably, the outer surface of the procapsid is welded with multigroup first deep floor, the outer surface weldering of the back casing
It is connected to multigroup second deep floor.
Preferably, the outer surface of the middle casing is welded with multigroup third deep floor.
The utility model advantageous effect：The utility model be provided with procapsid, middle casing, back casing, top panel and below
Plate eliminates forging crossbeam, and the weight of babinet is greatly reduced, and the riser after thickening is no longer needed for the gusset knot of original gear case
Structure decreases welding sequence in this way while having saved material, shortens the manufacturing cycle, reduces the quantity of structural member,
To reduce welding difficulty and reduce workload, design modularization is used, design efficiency is improved, reduces design error.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 is the vertical view of the utility model；
