Description
Technical field
The invention belongs to continuously tracked vehicle and make the field, relate to a kind of part of continuously tracked vehicle, relate in particular to a kind of caterpillar wheel and use the excavating machine of this caterpillar wheel.
Background technology
Caterpillar wheel is a kind of in excavating machine and bulldozer chassis four-wheel one band, and its main effect is the weight that is supporting excavating machine and bulldozer, lets crawler belt advance along wheel.Caterpillar wheel have two and half to take turns and be formed by connecting mostly.
As everyone knows, the chassis vitals caterpillar wheel of excavating machine all is employed in inner filling lubricating oil, satisfying its normal need of work, and effectively guarantees its service life.This just requires two and half to take turns the bonded assembly caterpillar wheel and have good sealing property; Oil leakage phenomenon (leakage of oil make the bad and foreign matter of lubricity get into caterpillar wheel inside cause the wearing and tearing aggravation) can not appear in the middle cavity that is connected to form, and therefore is provided with float grease seal usually.But this is functional prevention.In case internal lubrication oil itself has been mixed with impurity, not only aggravates the relative wear of INT COMP, also can cause float grease seal to damage simultaneously directly or indirectly, develop into the ultimate failure property fault of caterpillar wheel then because of leakage of oil.At present, the oil leakage phenomenon occurrence frequency of excavating machine caterpillar wheel is high both at home and abroad, has become the maximum essential factor of malfunction and failure.
Caterpillar wheel left and right sides wheel body adopts the friction welding mode to connect (crimping) mostly at present, because of its intensity and the extensively employing of odds for effectiveness quilt, to replace traditional filled type welding process.But the crimping meeting produces the extruding projection in the crimping face both sides of wheel body, and this projection is accompanied by the crimping process and will produces oxide on the surface.And inboard oxide shedding is prone to pollute the lubricating oil in the wheel body, worsens oil quality.
Obviously there is difficulty in these oxides of machine up removal simultaneously.Have manufacturing firm that it is carried out shot-ball peening, effect is unsatisfactory, and the embedding of shot particle is stayed in the narrow slit.And, find also that in manufacturing practice the foreign matters such as steel cuttings behind the wheel body fine limit work also can be stayed wherein by embedding firmly, be difficult for finding, and be difficult to remove.
Therefore, those skilled in the art is devoted to develop a kind of impurity that makes can not get into working oil chamber, thereby guarantees the caterpillar wheel of cleanliness of lubricating oil and use the excavating machine of this caterpillar wheel.
Summary of the invention
In view of above-mentioned the problems of the prior art, technical matters to be solved by this invention is the easy pollution lubricating oil of the caterpillar wheel of existing technology.
A kind of caterpillar wheel provided by the invention comprises interconnective wheel body and rotating shaft, and said wheel body comprises revolver body and right wheel body; Wherein, also comprise the sealing pipe, said revolver body is connected through friction welding with right wheel body; Form circular working oil chamber in said revolver body and the right wheel body, said sealing pipe is located in the working oil chamber, and said sealing pipe is coaxial with said wheel body; One end of said sealing pipe and the seamless link of revolver body, the other end of said sealing pipe and right wheel body are tightly connected.
In a preferred embodiments of the present invention, also be provided with groove on the said revolver body, an end of said sealing pipe inserts said groove and is connected with the interference of said revolver body.
In another preferred embodiments of the present invention, the other end of said sealing pipe and right wheel body are tightly connected through friction welding.
In another preferred embodiments of the present invention, also be provided with the slit on the said right wheel body, the other end of said sealing pipe inserts said slit and said right wheel body is tightly connected.
In another preferred embodiments of the present invention, said revolver body, right wheel body are identical with the manufacturing materials of sealing pipe.
The present invention also provides a kind of excavating machine, comprises the chassis, comprises like above-mentioned caterpillar wheel in the said chassis.
Caterpillar wheel of the present invention and excavator structure are simple, convenient, have higher efficient and economy, have strengthened the Joint strenght of wheel body; And actv. has completely cut off harmful zone; Played the effect that stops impurity, be convenient to the cleaning and the cleaning of working oil chamber simultaneously, guaranteed that cleanliness of lubricating oil is up to standard; Thereby reduce the caterpillar wheel oil spill rate that causes because of cleanliness level is bad, prolong its service life.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of embodiments of the invention.
Among the figure: 1 wheel body, 2 sealing pipes, an end of 21 sealing pipes, the other end of 22 sealing pipes, 3 working oil chambers.
The specific embodiment
Below will combine accompanying drawing that the present invention is done concrete explaination.
A kind of caterpillar wheel of embodiments of the invention as shown in fig. 1 comprises interconnective wheel body 1 and rotating shaft (not shown).Wheel body 1 comprises revolver body 11 and right wheel body 12, wherein, also comprises sealing pipe 2.Revolver body 11 and right wheel body 12 are connected through friction welding, form circular working oil chamber 3 in revolver body 11 and the right wheel body 12.Sealing pipe 5 is located in the working oil chamber 3, and sealing pipe 2 is coaxial with wheel body 1, an end 21 and 11 seamless links of revolver body of sealing pipe 2, and the other end 22 of sealing pipe 2 is tightly connected with right wheel body 12.
