Description
Technical field
The utility model relates to field of track traffic, and in particular to a kind of electric train gear-box upper and lower box mould fitter
Dress.
Background technique
Subway a large amount of vehicles in various regions have arrived overhaul life, and time is pressing and the task is heavy, should quantity performed, guarantee quality again.
Currently, assembling gear-box scheme is to make marks by record to realize, using gear-box in overhaul gear-box mould assembling assembling
End cap is fixed, and is easy to appear bearing in assembling hoisting process and is collided with cabinet, and gear box end cover is damaged deformation, gap
Debugging inaccuracy, gear-box assembling quality cannot be guaranteed.Happy safe 5188 sealants used when mould assembling gear case body are easy
It is attached to gear-box end to cover, will cause the abrasion of gear box end cover when removing 5188 sealant using white knife steel, use other
Method can consume more working hours, and working efficiency reduces.For this purpose, proposing a kind of electric train gear-box upper and lower box mould assembling tooling.
Utility model content
To solve the above problems, the utility model provides a kind of electric train gear-box upper and lower box mould fitter
Dress, can solve the problem of mentioning in background technique.
The utility model is achieved through the following technical solutions:
A kind of electric train gear-box upper and lower box mould assembling tooling, the mould assembling tooling are made of high strength alloy steel, warp
Quenching heat treatment, hardness is higher than gear case body both sides end cap with intensity, and the mould fitter, which loads onto, is equipped with through-hole, the through-hole
With original threaded hole accurate fit on gear case body, the internal diameter of the mould assembling tooling is identical as axle diameters.
The beneficial effects of the utility model are: hardness is higher than gear box end cover after this mould assembling tooling is quenched heat treatment, no
It is prone to wear, long service life.Mould assembling tooling intensity is high, is not susceptible to deform, and process gap is debugged accurate after guarantee.Mould assembling
Tooling can be used white knife steel and remove 5188 sealants adhered to when mould assembling, improve production efficiency.The bolt hole of mould assembling tooling
It is processed with internal diameter referring to gear box end cover bolt hole and axle diameters, guarantees assembling quality.This mould assembling tooling is safe and reliable, is convenient for
It is widely used in practice in engineering.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the left view structural representation of the utility model.
In figure: 1, mould assembling tooling；2, through-hole.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figs. 1-2, a kind of electric train gear-box upper and lower box mould assembling tooling mainly passes through imitated gear-box output
The technical issues of hubcap and the mould assembling tooling 1 made solve output shaft bearing positioning, and gap adjusts, which uses
High strength alloy steel is made, and is quenched heat treatment, and hardness is higher than gear case body both sides end cap with intensity, in lifting, vehicle
Being pressed in mould fitter under the gravity of axis and filling will not cause the abrasion of damaging of mould assembling tooling 1 with deformation on 1, mould assembling tooling 1 is prolonged
It is durable.Through-hole 2 is installed, which processes referring to the bolt hole position of gear case body, can be with gear-box in mould assembling tooling 1
Threaded hole accurate fit on cabinet, the internal diameter of mould assembling tooling 1 is identical as axle diameters, mould assembling assemble when with axle fit clearance
It is small, it not will cause axle shaking, process debugging assembly is accurate after guarantee.
Principle of the utility model by original gear case body both sides end cap, extension design, by utilizing original gear
The screw thread of case upper and lower box passes through through-hole 2 with bolt and mould assembling tooling 1 is fixed with gear case body, can not consolidate originally
The output shaft of fixed lifting can be convenient lifting, carry out output shaft bearing installation, and bearing clearance adjustment greatly facilitates output shaft
Bearing installation is debugged with gap.Happy safe 5188 sealants used when mould assembling gear case body are liable to stick in mould assembling tooling 1,
After mould assembling tooling 1 is using quenching treatment, when removing happy safe 5188 sealant using the white knife steel of high rigidity, mould fitter not will cause
Fill 1 abrasion or mild wear.
The utility model provides a kind of rail traffic transmission system, and gearbox output shaft repairs assembling scheme, and not only
It is limited to described in specification and embodiment.Therefore it is all according to mechanism described in present utility model application the scope of the patents, feature and original
Done changes or modifications are managed, should be included in the utility model patent application range.
