Splet21. sep. 2016 · If joints have surface contact, they are called Lower pair (as with a pin surrounded by a hole). If joints have point or line contact, they are called Higher pair. • The main practical advantage of lower pairs over higher pairs is their better ability to trap lubricant between their enveloping surfaces. 6 6.

The contact stress is thus smaller for lower pair joints as compared to higher pair joints. Lower pair joints have a long service life because the wear and stress are spread over a larger surface area of contact, and they allow better lubrication. The ... unmh emergency room
