Hole-Wedge Effect of Friction Pair and Its Control Mechanism
Abstract: A special phonomenon
of self-lubrication compensation named hole-wedge effect was found in a bionic
porous friction pair, meanwhile the origin and regularity of this effect and
its tribological behaviors were discussed in this paper. The process of
self-circulating compensation of lubrication was modeled, and taking ferrofluid
as lubricant a series of experiments were designed and done. Researches show
that: the hole effect will produce self-compensation migration of lubricant in
the holes to interface, and accordingly the wedge effect will exert a
directional laminar flow, thus by well design the synthesis of these two
effects can be used to obtain self-circulating compensation of lubrication in
porous friction pair, which can significantly improve the stability and
tribological performance of friction pairs.
