Description
[technical field]
The utility model relates to a kind of high abrasion silencing chain.
[background technique]
All the time, known silencing chain is carrier bar is plane structure, and rolling pin is round pin or special-shaped pin form.Due to silencing chain chain plate hole and rolling pin hinged, and have guide row and non-guide row point, do not relatively rotate at guide row inner plate and rolling pin, relatively fixing, turn round and look at its wearing and tearing very little, can ignore.And be hinged with at non-guide row chain plate hole and rolling pin and relatively rotate, more than 95% of its chain length wearing and tearing all occur in herein.And at two adjacent guide row and non-guide row chain board diameter cross assembly, so the not enough whole chain of effective pressure-bearing surface of its carrier bar and rolling pin wide 50%, the bearing area of bush roller chain reach whole chain wide more than 80%, so its wear resistance of common quiet chain comparatively bush roller chain is poor.Also be bush roller chain commercially one of prevailing principal element so far.
