Abstract:
The high-speed multicycle impact and speed, load fluctuant
characteristics is a key factor that has inflnence on reststance
to wear and resistance to multicycle impact for automotive
engine chain . The main wear mechanism of automotive engine
chain is form, extend and flaking of crack for top layer of pin
and bush, and its change rule of wear curve is different trorn
mediurn-low speed drive roller chain 's. The effective methods
that increases resistance to multicycle impact for roller are to
ensure that the roller has sufficient strength and plasticity
and to adopt suitable shaped technics.
Key words: Automotive
chain Wear curve Fatiguewear Resistance to
multicycte impact Plastic deformation Cycle feature
