The
advantages of powder metallurgy gear:
1.low
cost, high efficiency, molding in one time, no need to process tooth after
forming.
2.due
to its processing properties, powder metallurgy can make oil-bearing parts,
forming free lubrication parts, but some are worse than oil bath lubrication,
belong to boundary lubrication.
3.No
waste in gear forming process, one of the best of resource utilization for the
steel.
