Between there is gap, i.e. gap includes axial gap and radial clearance.Guiding rib 5 embeds and coordinates when mating groove 4 middle, leads
To the most all having gap d (i.e. axial gap) between the both sides and the side of mating groove of rib 5, gap d is the opening of mating groove 4
The 1%-10% of width D.The mating groove 4 that the guiding rib 5 that traction load bearing unit 2 protrudes above is recessed on rotation wheel 1 does not contacts, only
When traction load bearing unit 2 lateral shift, guiding rib 5 and mating groove 4, in a side contacts, play the guiding role, thus avoid stress
Uneven cause protrude guiding rib 5 abrasion thus affect the life-span of whole traction load bearing unit 2.
In the present embodiment, on the first work surface 21, the surface area of guiding rib 5 is less than the surface area of the first work surface 21
30%；On the second work surface 22, the surface area of guiding rib 5 is less than the 30% of the surface area of the second work surface 22.Thus it is ensured that work
Make the face most of area more than 70% to contact for the rolling surface taking turns 1 with rotation, make traction load bearing unit 2 and the rotation of bandlet shape
Force dispersion when runner 1 coordinates, it is to avoid traction load bearing unit 2 local pressure is excessive and easy broken belt, it is ensured that safe and reliable.
In the present embodiment, as it is shown in figure 1, have the protective layer 41 reducing friction and wear on the inner surface of mating groove 4.Excellent
Selection of land, protective layer 41 can be polytetrafluoroethylene floor, perfluoroalkoxy basic unit, ceramic layer or the one of which of the coat of metal.
