WebFriction. Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two surfaces are in contact and moving ... WebThe first rolling member 211 is connected to the transmission body 2 through the connecting seat 212. , the first rolling member 211 is in rolling fit with the limiting track 11 . In this way, the rolling fit is beneficial to reduce friction, reduce power loss, and improve the transmission efficiency of the linear reciprocating transmission ...
