Be passed through lubricating oil in annular groove 731, lubricating oil can either the inserted terminal to grafting axis 71 adequately lubricated, while again can
The heat generated to the semicircle cambered surface friction of grafting axis 71 and midfoot support post 73 absorbs, and then plays cooling effect,
And then grafting axis 71 is eliminated because deforming caused by fever, and then ensure that the precision of benchmark idler wheel 72 on grafting axis 71；Base
Quasi- idler wheel 72 drives grafting axis 71 to rotate, and grafting axis 71 drives the upper surface rolling of the arcuately plate 74 of roller 76 by frictional force,
It realizes that the lubricating oil between roller 76 and vertical plate 741 is extruded between the binding face of grafting axis 71, realizes and obtained between binding face
To sufficient lubrication；The No.1 idler wheel 75 of 74 end of arc panel is driven to rotate while grafting axis 71 rotates, when No.1 idler wheel 75
On circular arc protrusion 751 contact grafting axis 71 when, arc panel 74 swing, and then arc panel 74 be detached from the contact of roller 76, roll
The arcuately 74 surface reverse slide of plate of column 76, when No.1 idler wheel 75 is detached from 71 relative rolling of grafting axis, arc panel 74 is again
Carry out contact roller 76；75 surface of No.1 idler wheel setting wear-resisting antiskid coating ensure that have between No.1 idler wheel 75 and grafting axis 71
Effect roll, and then guarantees that arc panel 74 is reliably detached between roller 76, finally ensure that lubricating oil is squeezed
It is pressed between the binding face of grafting axis 71, lubricates the inserted terminal of grafting axis 71 adequately.
