In the press machines or roll-in machinery of the industries such as material.
As shown in Fig. 2, in the present embodiment, installed using broken line cloth between two transmission shafts 21,22 and the first output shaft 41
Meter, i.e. the first transmission shaft axle center O2, second driving shaft axle center O3 and the first output shaft axle center O4 are not on same straight line, this makes
The drive centre distancc for obtaining gear increases, and the bearing capacity of gear-box is stronger.
In another embodiment of the present invention, in order to enable the gear-box of the present invention can preferably be suitable for chemical industry row
The soapmaking equipment of industry, the present invention have also carried out further optimization to the oil sealing of gear-box.Due in the raw material and product of soapmaking
Include more alkaline matter and lipid material, this proposes the sealing performance of the angular gear case used in soap making machine
Higher requirement.Since the sealability of angular gear case input shaft or output shaft oil sealing depends on the thickness of sealing surface oil film：
Thickness is excessive, and oil sealing can leak；Thickness is too small, it may occur however that dry friction causes the abrasion of oil sealing and axis；There is no oil film, then easily
Cause fever, abrasion.When gear-box for a long time in strong basicity working environment when, alkaline matter easily with oil film occur saponification destroy
Oil film leads to greasy property decline and the oil seal leak of oil film, moistens so that alkaline matter is further penetrated into from leakage place
In lubricating oil, this aspect can cause it that saponification occurs with the lubricating oil in gear-box, and then generate precipitation and emulsification,
So that the quality of lubricating oil deteriorates rapidly；The acid-base property of another aspect lubricating oil is also easy to metal portions such as gears in gear-box
Part causes corrosion so that the antirust and antiseptic property of lubricating oil reduce rapidly.To solve above-mentioned problem, the present invention innovatively uses
Oil sealing of the specially treated outside framework oil seal as gear-box.
In one embodiment, input oil sealing 13 of the invention, the first output oil seal 42 and the second output oil seal 52 use
Outside framework oil seal, aliphatic acid dispersion processing of the inner ring side through graphene of the outside framework oil seal, steps are as follows：
(1) graphene and aliphatic acid are uniformly mixed, obtain the aliphatic acid dispersion liquid of graphene；
(2) the aliphatic acid dispersion for the graphene for obtaining step (1) is in the inner ring side of outside framework oil seal；
(3) outside framework oil seal after coating step (2) dries a period of time, you can for assembling, (assembly uses conventional
Outside framework oil seal assembly method).
Preferably, the graphene used in step (1) is multi-layer graphene, i.e., the number of plies of wherein most of graphene films is more than
1 layer, in this way for single-layer graphene, not only cost is relatively low, and effect is also preferable.
Preferably, the aliphatic acid used in step (1) is C6~C20 aliphatic acid, preferably unsaturated fatty acid, more preferably
Lauric acid, oleic acid, linoleic acid or combinations thereof object.
Preferably, the mass ratio of the graphene in step (1) and aliphatic acid is 1:3~1:10, more preferably 1:4.
Preferably, the drying in step (3) uses vacuum drying oven, drying temperature to control in 30~50 DEG C, more preferably 40
℃；Drying time was controlled at 30~90 minutes, more preferably 60 minutes.
After the above method is handled, inner ring side (the i.e. sealing surface namely gear-box of outside framework oil seal and axis of outside framework oil seal
When operation at oil film formation) it is coated with graphene, contain aliphatic acid in the lamella of graphene.Inherently very due to graphene
Excellent lubriation material has facilitation to the greasy property of oil film；Again due in macroscopically graphene coat mechanicalness
Matter is softer, and the easily opposite sliding between microcosmic upper graphene sheet layer, therefore is easy to make compensation to the thickness change of oil film,
So that oil film thickness is maintained always in suitable range, to enhance the sealing performance of oil film.And due to unsaturated fatty acid
The double bond contained can be more securely incorporated between the lamella of graphene, under π-π effects when gear-box is in alkaline ring
When working in border, due to the neutralization of aliphatic acid, most alkaline matters can be blocked at outside framework oil seal, and can not be light
Easily penetrate into lubricating oil.This has greatly delayed the deterioration speed of lubricating oil, without being replaced as frequently as lubricating oil, and only needs
Outside framework oil seal is regularly replaced, operation and the maintenance cost of gear-box are greatly reduced.
Inventor is respectively by the bone of the aliphatic acid dispersion liquid of the graphene without above-mentioned processing and through different ratio processing
Frame oil sealing is assemblied on gear-box, records and the gear-box for comparing the present invention uses for a long time in the soapmaking equipment of identical operating mode
The case where, the results are shown in table below：
| The processing mode of outside framework oil seal | Outside framework oil seal replacing construction (day) for the first time | Lubricating oil replacing construction (day) for the first time |
| It is untreated | 62 | 89 |
| Graphene：Lauric acid 1:4 | 102 | 168 |
| Graphene：Lauric acid 1:7 | 98 | 125 |
| Graphene：Lauric acid 1:10 | 110 | 110 |
| Graphene：Oleic acid 1:4 | 90 | 160 |
| Graphene：Oleic acid 1:7 | 97 | 155 |
| Graphene：Oleic acid 1:10 | 104 | 124 |
| Graphene：Linoleic acid 1:4 | 82 | 205 |
| Graphene：Linoleic acid 1:7 | 98 | 158 |
| Graphene：Linoleic acid 1:10 | 96 | 133 |
As seen from the above table, using untreated outside framework oil seal, the using effect in alkaline environment is not satisfactory, skeleton oil
Envelope easily loss, and lubricating oil is perishable.And the outside framework oil seal of the above method of the present invention processing is used, the use in alkaline environment
Effect has different degrees of promotion.Wherein, especially with graphene：Linoleic acid is 1:4 graphene dispersing solution treated bone
Frame oil sealing effect is the most outstanding, makes the replacement cycle of gear box lubricating oil extend 2 times and have a surplus, although outside framework oil seal is more
It changes frequency relative to other processing modes slightly to be risen, but in general still greatly reduces the operation of gear-box
And maintenance cost, because graphene and linoleic dosage are seldom and price is not very expensive yet.On the other hand, it is contemplated that
Oleic acid is cheap, and it is also more apparent for the promotion of the sealing effect of outside framework oil seal, selects graphene：Oleic acid is 1:4
Graphene dispersing solution processing outside framework oil seal be also a kind of higher selection of cost performance.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that the ordinary skill of this field is without wound
The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all technician in the art
Pass through logic analysis, reasoning or the limited available technology of experiment on the basis of existing technology under this invention's idea
Scheme, all should be in the protection domain being defined in the patent claims.
