Frame, 70 needle bearings.
Specific embodiment
The utility model is further described in detail with reference to the accompanying drawings and detailed description.It needs to illustrate
It is that the feature in embodiments herein and embodiment can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other than the one described here other modes, therefore, the protection scope of the utility model is simultaneously
It is not limited by the specific embodiments disclosed below.
Some embodiments according to the present utility model are described referring to Fig. 1 to Fig. 2.
As depicted in figs. 1 and 2, according to the track pin rolling mechanism of one embodiment provided by the utility model, comprising: three
Angular frame 10；Three groups of self-resetting hydraulic equipment 20, are fixed on triangular framing 10；Three groups of rolling wheel groups 30, rolling wheel group
30 are individually fixed in self-resetting hydraulic equipment 20 close to the head of triangular framing 10, and rolling wheel group 30 includes multiple rolling
Wheel, wherein rolling wheel group 30 is under the action of self-resetting hydraulic equipment 20 along the axial-movement of self-resetting hydraulic equipment 20.
By using hydraulic device 20 be used as power source, track pin rolling mechanism it is stable, and then using its processing
Pin class part, significantly improve the hardness and roughness of crawler belt pin surface, fatigue life also increases significantly.Wherein, often
The head of group self-resetting hydraulic equipment 20 is fixed with a rolling wheel group 30, and rolling wheel group 30 includes multiple rolling wheels, passes through rolling
Pinch roller rolls track pin, and crawler belt pin surface forms flow harden layer by squeezing.
Optionally, the angle between the axis of three groups of self-resetting hydraulic equipment 20 is 120 °.
Since the angle between the axis of three groups of self-resetting hydraulic equipment 20 is 120 °, thus two groups of adjacent rolling wheel groups
The distance between 30 is equal, and three groups of rolling wheel groups 30 and the center of triangular framing 10 are equidistant, and are evenly distributed, into
And make the uniform force of rolling wheel, that is, the rolling power for being applied to track pin is more uniform, and more fully to the rolling of track pin,
Further increase the hardness, roughness and fatigue life of the rolling of track pin.
