Lower pair joint
WebFigure 1(a). The number of links, lower pairs, and higher pairs. (a) If the contact between links 3 and 4 is regarded as a lower pair then the number of links, the number of lower pairs, and the number of higher pairs, respectively, are n8, j10, and j 1== =12 (4) Substituting Eq. (4) into Eq. (1), the mobility of the mechanism is 8 j1 j1 2j1 j1 ... WebLower 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 degrees of freedom for a lower pair joint are usually fewer, as the requirement for area contact between the members constrains the joint geometry.
