Abstract
The invention discloses a tooth-type structure of a support chain wheel of a hydraulic excavator and the hydraulic excavator. The tooth-type structure of the support chain wheel of the hydraulic excavator comprises a support chain wheel and is characterized in that a plurality of tooth structures are arranged on the circumference of the support chain wheel, the support chain wheel is of an axisymmetric structure, and the multiple tooth structures are distributed on the circumference of the support chain wheel at equal intervals; a groove structure is formed between every two adjacent tooth structures, and the groove structures are smooth transition type groove structures. According to the tooth-type structure of the support chain wheel of the hydraulic excavator and the hydraulic excavator, an original mode that a crawler assembly makes contact with a support chain wheel is changed, the driving moment transmitted to the support chain wheel is increased, and the rotating capacity of the support chain wheel is improved.
Description
Technical field
The present invention relates to a kind of technical field of hydraulic excavator, particularly relate to the tooth-like structure of a kind of hydraulic excavator holder sprocket wheel and hydraulic excavator.
Background technology
At present, the holder sprocket wheel adopted in construction machinery and equipment crawler body, has the effect supporting track rail assembly and slide continuously.The key point of existing holder chain sprocket structure design, reduce inside configuration steering resistance, various structures scheme is mentioned in all kinds of patent and document, but being confined to holder sprocket wheel wheel body contour structures is columniform feature, track rail assembly can only by Gravitative Loads in holder sprocket wheel, have lost the drive torque of crawler belt, cause holder chain turning power lower.Therefore, often there is the phenomenon that holder sprocket wheel does not turn in fault after sale.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing limitation, provides the tooth-like structure of a kind of hydraulic excavator holder sprocket wheel and hydraulic excavator, adds the drive torque passing to holder sprocket wheel, improves the turning power of holder sprocket wheel.
For achieving the above object, technical scheme of the present invention is achieved in that
The tooth-like structure of a kind of hydraulic excavator holder sprocket wheel, comprise holder sprocket wheel, wherein, described holder sprocket periphery place has some toothings.
The tooth-like structure of above-mentioned hydraulic excavator holder sprocket wheel, wherein, described holder sprocket wheel structure axisymmetricly.
The tooth-like structure of above-mentioned hydraulic excavator holder sprocket wheel, wherein, some described toothings are in the equidistant arrangement in described holder sprocket periphery place.
The tooth-like structure of above-mentioned hydraulic excavator holder sprocket wheel, wherein, some described toothings have groove structure between any two.
The tooth-like structure of above-mentioned hydraulic excavator holder sprocket wheel, wherein, described groove structure is the groove structure of rounding off.
Also comprise a kind of hydraulic excavator, wherein, comprise the tooth-like structure of hydraulic excavator holder sprocket wheel as described in above-mentioned any one.
The present invention is owing to have employed above-mentioned technology, and the good effect of generation is:
The present invention, by changing original track rail assembly and the way of contact of holder sprocket wheel, increases the drive torque passing to holder sprocket wheel, improves holder sprocket rotation ability.
Accompanying drawing explanation

In further embodiment of the present invention, some toothings have groove structure 3 between any two.
In further embodiment of the present invention, groove structure 3 is the groove structure of rounding off.
User can further be familiar with characteristic of the present invention and function according to following explanation,
In the present embodiment, also comprise a kind of hydraulic excavator, wherein, comprise the tooth-like structure of hydraulic excavator holder sprocket wheel as above-mentioned any one.
In the present embodiment, concrete comprises a kind of hydraulic excavator holder chain-teeth type structure, is the multiple tooth shape in cross section by the profile design of holder sprocket wheel 1 wheel body; This improvement, revolutionizes crawler belt and the way of contact of holder sprocket wheel 1, holder sprocket rotation ability is improved.
Certainly, the holder chain sprocket structure in the present embodiment also can be the gear type structure shown in Fig. 2, and the quantity of toothing 2 is many compared with toothing 2 quantity in Fig. 1, also can reach above-mentioned technique effect.
The foregoing is only preferred embodiment of the present invention; not thereby embodiments of the present invention and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilizations specification sheets of the present invention and diagramatic content and apparent change obtain in protection scope of the present invention.
