The invention provides a kind of anti-fall off chain directive wheel, it is related to technical field of engineering machinery.The anti-fall off chain directive wheel includes directive wheel body；The outer circumference surface of the directive wheel body sets fluted, and the groove is used to be socketed the chain muscle of crawler belt.Anti-fall off chain directive wheel of the invention, using the groove of parcel socket caterpillar chain muscle, limits the lateral sliding of crawler belt, reduces the risk of the de- chain of crawler belt.On this basis, present invention also offers a kind of band of excavator four-wheel one.
Description
Technical field
The present invention relates to technical field of engineering machinery, more particularly to a kind of anti-fall off chain directive wheel and the band of excavator four-wheel one.
Background technology
For excavator machine hand, it is a problem through being commonly encountered that crawler belt takes off chain (or referred to as " exceeding the bounds ").For
For excavator, it is inevitable that chain is taken off once in a while, because the environment of excavator work is more severe, crawler belt enters soil or stone
De- chain will be caused.But if excavator is often taken off if chain, that is accomplished by finding reason.
The running gear of excavator is made up of the band of four-wheel one, has many reason for cause excavator de- chain, but all may be used substantially
To be classified as three classes：
First, directive wheel reason.Because only directive wheel can be in four-wheel (directive wheel, thrust wheel, driving wheel, carrier wheel)
Movable, moving part abrasion and directive wheel central shaft wear and tear, and can all cause directive wheel to be swung relative to crawler belt, draw
Crawler belt is played to exceed the bounds.
2nd, crawler belt reason.Because stress of upper time and abrasion cause crawler belt excessively loose, crawler belt is caused to exceed the bounds.
3rd, chain guard reason.Because the crawler belt that chain guard abrasion causes is exceeded the bounds.Chain guard is located at thrust wheel and directive wheel
Outside.Once wearing and tearing, chain rail is easily slided into outside chain guard chain guard, causes crawler belt to exceed the bounds.
In addition, also there is the reasons such as equipment making technique is poor, road conditions are bad, operating personnel's misoperation.
In above-mentioned reason, the topmost reason for causing crawler of excavator to exceed the bounds is that directive wheel is asked with the cooperation of crawler belt
Topic.
The content of the invention
It is an object of the invention to provide a kind of anti-fall off chain directive wheel and the band of excavator four-wheel one, to solve in the prior art
Crawler of excavator frequently take off chain problem.
To achieve these goals, the present invention uses following technical scheme：
A kind of anti-fall off chain directive wheel that the present invention is provided, including directive wheel body；The outer circumference surface of the directive wheel body
Set fluted, the groove is used to be socketed the chain muscle of crawler belt.
Further, described this body by integral forming of directive wheel.The technical scheme has technical effect that：Integrally formed guiding
Wheel body has more excellent structural strength, while processing and fabricating is also more convenient quick.
Further, the depth bounds of the groove is more than or equal to 5 centimetres, less than or equal to 10 centimetres.The skill of the technical scheme
Art effect is：Height and construction operating mode according to caterpillar chain muscle, between 5 to 10 centimetres, it is prevented the depth bounds of groove
The best results of de- chain.
Further, the outer circumference surface of the directive wheel body is provided with shoulder block ring；The shoulder block ring is located at the groove
Bottom land.The technical scheme has technical effect that：Shoulder block ring has booster action, gos deep into inside chain muscle, strengthens jointly with groove
The mating connection of directive wheel body and crawler belt, prevents the de- chain of crawler belt sideslip.
Further, also including wheel shaft and rolling bearing；Centre bore of the wheel shaft through the directive wheel body；The rolling
The quantity of dynamic bearing be two, along the length direction of the wheel shaft be disposed side by side on the centre bore of the directive wheel body with it is described
Between wheel shaft.The technical scheme has technical effect that：Wheel shaft and two rolling bearings being arranged side by side, being capable of receiving crawler belt
Power is fifty-fifty delivered on wheel shaft, has disperseed the radial and axial stress of rolling bearing and directive wheel body.
Further, also including oil-sealing sleeve；The oil-sealing sleeve is arranged at two outer ring surfaces of the rolling bearing and is led with described
Between centre bore to wheel body；Formed between the wheel shaft, two rolling bearings and the oil-sealing sleeve one it is closed
Annular oil cavity.The technical scheme has technical effect that：On the one hand oil-sealing sleeve forms closed lubricant reservoir, on the other hand makes
Two rolling bearing stress are obtained to be more uniformly distributed.
Further, the wheel shaft is provided with oil storage tank towards the anchor ring of the annular oil cavity.The technology effect of the technical scheme
It is really：Oil storage tank is used to produce Volume Changes to compensate because of temperature change lubricating oil, the pressure of systems stabilisation lubricating oil
Power.
A kind of band of excavator four-wheel one that the present invention is also provided, including driving wheel, thrust wheel, carrier wheel, tensioning apparatus, shoe
Band, and above-mentioned anti-fall off chain directive wheel；The driving wheel, the thrust wheel, the carrier wheel and the anti-fall off chain directive wheel
It is successively set on the crawler belt inner side；The tensioning apparatus is connected with the directive wheel body.
The beneficial effects of the invention are as follows：
Using parcel, the groove of socket caterpillar chain muscle, the lateral sliding of crawler belt is limited, reduce the wind that crawler belt frequently takes off chain
Danger, improves the efficiency of construction of excavator.
