The utility model also provides a drive axle including the above main reducing gear. The utility model also provides a loading including the drive axle. One end of the dust cover of the main reducing gear provided by the utility model is inserted into the groove formed in the shell, so that the path of the dust entering into the oil seal is prolonged, thus reducing entering of the external dust, abrasion of the oil seal is reduced, service life of the oil seal is improved, and failure rate of the whole axle is reduced.
Description
Technical field
The utility model relates to engineering machinery field, relates in particular to a kind of main reducing gear, ransaxle and loader.
Background technique
Loader is as a kind of important engineering machinery, and the application in production and construction is more and more extensive.
Oil sealing damages and in ransaxle fault, occupies larger comparison, and the reason that oil sealing damages is mainly to cause the wearing and tearing of oil sealing because inner or outside impurity enters seal operation surface.
Shown in Fig. 1, in prior art, on the shell 5 of main reducing gear, offer an opening, opening inserts a flange 3, and locking nut 1 is by plain washer 2 fastening flanges 3.Between flange 3 and shell 5, be folded with oil sealing 4.
Main reducing gear dust-proof cover general structure is fairly simple, only has one deck dust-proof mechanism, and one end of dust-proof cover is to cover on the side of shell.In using process, the dust-proof cover of prior art can not effectively prevent that dust from carrying out oil sealing working position, and dust is easy to enter in oil sealing from the place of dust-proof cover and housing contacts.And at work, once dust enters sealing position, very quick-wearing of oil sealing, causes leakage of oil.
Model utility content
In order to overcome the not good technical problem that causes oil sealing wearing and tearing of main reducing gear dust-proof cover dust-proof effect in prior art, the utility model provides a kind of main reducing gear, ransaxle and loader.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
The utility model provides a kind of main reducing gear, comprises the shell covering at outside described main reducing gear, embeds a flange in described shell by the opening of described shell, between described flange and described shell, is added with oil sealing, and described main reducing gear also comprises:
Rotatable dust-proof cover, is covered on the upper surface of described oil sealing, and one end of described dust-proof cover is connected with described flange, and the other end of described dust-proof cover inserts in the groove that described case surface offers.
Furthermore, in described main reducing gear, the intermediate portion of described dust-proof cover covers the upper surface of described oil sealing.
Furthermore, in described main reducing gear, a drift angle of described groove is surrounded by described dust-proof cover, and the drift angle being surrounded by described dust-proof cover carries out chamfering.
Furthermore, in described main reducing gear, one end of described dust-proof cover upwards bends, and the other end of described dust-proof cover is bent to form a horn-like opening downwards.
The utility model also provides a kind of ransaxle, comprises main reducing gear as above.
The utility model also provides a kind of loader, comprises ransaxle as above.
The beneficial effects of the utility model are: the dust-proof cover of main reducing gear of the present utility model, and insert in the groove that shell offers its one end, makes dust enter the path of oil sealing elongated, thereby reducing external dust enters, reduce the wearing and tearing of oil sealing, improve the oil sealing life-span, thereby reduce the rate of fault of whole bridge.
Brief description of the drawings
Fig. 1 represents the structural representation of the dust-proof cover of main reducing gear setting of the prior art;
Fig. 2 represents the structural representation of the dust-proof cover of the main reducing gear setting in the utility model embodiment.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model provides a kind of main reducing gear, comprise the shell covering at outside described main reducing gear, embed a flange in described shell by the opening of described shell, between described flange and described shell, be added with oil sealing, described main reducing gear also comprises: dust-proof cover, be covered on the upper surface of described oil sealing, one end of described dust-proof cover is connected with described flange, and the other end of described dust-proof cover inserts in the groove that described case surface offers.
Specifically, in main reducing gear of the present utility model, the opening of shell embeds a flange, between flange and shell, be added with oil sealing, the upper surface lid of oil sealing is established a dust-proof cover, and one end of dust-proof cover is connected with flange, in the groove that the other end insertion case surface of dust-proof cover is offered.Like this, dust enters the process of oil sealing working surface, can be introduced in groove, then walk around the dust-proof cover inserting in groove, then just can enter in oil sealing.Make dust enter the path of oil sealing elongated, enter thereby reduce external dust, reduce the wearing and tearing of oil sealing, improve the oil sealing life-span, thereby reduce the rate of fault of whole bridge.
Shown in Fig. 2, in main reducing gear of the present utility model, the upper surface lid of oil sealing 4 is established a dust-proof cover 6, and one end of dust-proof cover 6 is connected with flange 3, in the groove 7 that the other end insertion case surface of dust-proof cover 6 is offered.External dust enters in the process of working surface of oil sealing 4, can be through inserting by the lower end of dust-proof cover 6 the U-shaped gap that groove 7 forms together, and this gap enters working surface to dust and plays effective interception.
The intermediate portion of dust-proof cover 6 covers the upper surface of oil sealing 4, can play better sealing effect to oil sealing 4.Dust-proof cover 6 one end upwards bend, and the other end of dust-proof cover 6 bends downwards, make whole dust-proof cover form a horn-like opening.Dust-proof cover 6 High Rotation Speeds at work.Most of dust is blocked in U-shaped gap place, because dust-proof cover High Rotation Speed produces stronger operating on centrifugal force.Under the effect of centrifugal force, dust can be discharged to outside automatically.
The drift angle 71 that groove 7 is surrounded by dust-proof cover carries out chamfering, makes more can the fit position of dust-proof cover 6 bottoms bendings of this drift angle 71, enters oil sealing thereby can effectively reduce dust from the external world.
The utility model also provides a kind of ransaxle, comprises main reducing gear as above.
It should be noted that, this ransaxle is the ransaxle that comprises above-mentioned main reducing gear, and above-mentioned main reducing gear embodiment's implementation is equally applicable in the embodiment of this ransaxle, also can reach identical technique effect.
The utility model also provides a kind of loader, comprises ransaxle as above.
It should be noted that, this loader is the loader that comprises above-mentioned ransaxle, and above-mentioned ransaxle embodiment's implementation is equally applicable in the embodiment of this loader, also can reach identical technique effect.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
