Embodiment
In order to preferably explain the present invention, in order to understand, below in conjunction with the accompanying drawings, by embodiment, to this hair
It is bright to be described in detail.
As shown in Figure 1 to Figure 3：Present embodiment discloses a kind of Walk Part of Shearer, including splined shaft 12, driving wheel 13,
First road wheel group and the second road wheel group；
Wherein, the splined shaft 12 is the coal-winning machine walking described in the present embodiment by being connected with external drive equipment
Portion provides power.
In detail, the splined shaft 12 described in the present embodiment and the key connection of driving wheel 13, and the drive can be driven
The synchronous axial system of driving wheel 13；
Splined shaft 12 described in the present embodiment and the key connection of driving wheel 13, simultaneously, the splined shaft 12 relative to
For driving wheel 13, power transmission is not only acted as, and the splined shaft 12 described in the present embodiment also carries " driving wheel
The effect of axle "；Therefore the fixed driving wheel 13 is supported without live axle is specially set again in the present embodiment；And with
The rotation of splined shaft 12, while also drive the driving wheel 13 to be rotated.
In addition, the first road wheel group described in the present embodiment includes the first live axle 4, first and skate 901 and the
One road wheel 2；
First live axle 4 is respectively with described first and skate 901 and the key connection of the first road wheel 2；
The second road wheel group includes the simultaneously road wheel of skate 902 and second of the second live axle, second；
Second live axle is respectively with described second and skate 902 and the second road wheel key connection；
Simultaneously simultaneously skate engages connection to skate 901 and second to the driving wheel 13 with described first respectively, and can reach described in drive
First and skate 901 and described second and skate synchronous axial system；
Described first and skate 901 can drive the synchronous axial system of the first road wheel 2；
Described second and skate can drive the second road wheel synchronous axial system.
From described above, compared with traditional Walk Part of Shearer, the Walk Part of Shearer described in the present embodiment
By setting two groups of road wheel groups to improve the bearing capacity of the first road wheel 2 and the second road wheel described in the present embodiment, drop
Pressure low and between skate and driving wheel 13, and then cause the Walk Part of Shearer described in the present embodiment in the course of work
Between middle gear and gear because engage and caused by wear and greatly reduce；Gear teeth fracture is additionally reduced to a certain extent
Risk, improve the service life of Walk Part of Shearer middle gear described in the present embodiment.
In addition, it is necessary to explanation is：The central point of driving wheel 13 described in the present embodiment and described first and skate 901
Central point and described second and the central point of skate be in triangle arrangement in the same plane；
Preferably, the triangle is isoceles triangle；
Specifically, the position between the driving wheel 13, first described in the present embodiment and skate 901 and second and skate three is closed
System be in angular distribution at grade, wherein the driving wheel 13 positioned at described first simultaneously skate 901 and described second side by side
The top of wheel 902 and respectively with described first and skate 901 and described second and skate 902 engage simultaneously passing power, and then band
Move first road wheel 2 and second road wheel rotates；Driving wheel 13 and the position of simultaneously skate described in the present embodiment
Setting not only saves space, it will also ensure that the first road wheel 2 described in the present embodiment and second road wheel is same
Step rotates.
The central point of the driving wheel 13 is located at the drift angle of the isoceles triangle, described first and skate 901 central point
It is located at two base angles of the isoceles triangle respectively with the central point of described second and skate 902.
That is, for first and skate 901 in the present embodiment compare driving wheel 13 with described second and skate 902
It is symmetrical, and engaged simultaneously with the driving wheel 13, and described first and skate 901 with described second and skate 902 also
It can mutually aid in engaging with the driving wheel 13, the described first simultaneously skate 901 and described second and skate 902 and driving
