Portion and wheel portion, axle portion are adapted to axis hole, and wheel portion is placed on the outside of graphite protecting bush, and card slot is additionally provided in axle portion, and card slot is equipped with and is used for
The snap ring of fixed axle portion, is fixed between snap ring and arm body by screw.
By using above-mentioned technical proposal, it is relative rolling between idler wheel and the release bearing of transmission gear, can reduces
Shift fork abrasion, and graphite protecting bush is sticked in the first mounting groove and the second mounting groove, can reduce the abrasion of idler wheel axle portion, and logical
The setting for crossing oil storage tank further increases the lubricant effect of idler wheel axle portion, and snap ring can be two semi-loops, is easily installed,
Snap ring is sticked in the card slot of axle portion, and is connected by screw to snap ring and arm body, while snap ring can also play graphite protecting bush
Further fixed function, structural stability is good, and is readily disassembled.
The utility model is further arranged to: the idler wheel is equipped with several microcellular structures, and several micropores form connection storage
The asphalt channel of oil groove and idler wheel outer wall.
By using above-mentioned technical proposal, by the asphalt channel of microcellular structure formation, the lubricating oil in oil storage tank can seep
It thoroughly on the outer surface of wheel portion, when operating, generates heat due to rubbing between idler wheel and release bearing, the thermal expansion of wheel portion surface makes
Lubricating oil overflows, and plays lubricating action, and when stopping working, wheel portion is cooling, and the lubricating oil in oil storage tank is inhaled again along axle portion
Entering in the hole of wheel portion, realizes self-lubricating, above structure self-lubrication is good, oiling again is only needed just after long-time use,
Long service life.
The utility model is further arranged to: the material of the idler wheel is fe-based alloy powder powder sintered compact.
By using above-mentioned technical proposal, idler wheel uses iron(-)base powder for primary raw material, makes of powder metallurgic method
At sintered body, there is enough intensity, and material internal has countless small holes in performance, it in the fabrication process can relatively freely
The technical advantage such as quantity, size, shape and the distribution of adjustment apertures, not only can be with trapped fuel, but also can be formed small and tortuous
Asphalt channel, play the role of self-lubricating.
The utility model is further arranged to: being additionally provided with reinforcing rib on the arm body.
By using above-mentioned technical proposal, increase the structural strength of arm body by reinforcing rib.
