The basic types and characteristics of dumpling chain four-bar mechanism application examples

Internal combustion engine, crane, train wheel, manual punching machine, planer, elliptical instrument, mechanical claw, window support, bus door opening and closing, folding umbrella, folding bed, toothpaste tube extubation machine, bicycle brake operating mechanism, etc.SPECIAL SAWING MACHINE Definition: A planar mechanism consisting of low-pair (rotational, mobile) connections. Features: There is a component that moves in a plane, called a connecting rod.SPECIAL SAWING MACHINE Features: ①Use low vice. Surface contact, large load, easy to lubricate, not easy to wear, simple shape, easy to process, easy to obtain high manufacturing accuracy. ② Changing the relative length of the rod, the movement law of the follower is different. ③ Rich connecting rod curves. Can meet different requirements.Effect of Magnesium on Aluminum Alloy Vacuum Brazed Joints Quick return exercise In the crank-rocker mechanism, when the crank and the connecting rod are collinear twice, the rocker is in two extreme positions, referred to as extreme positions. The angle 0 between the two cranks is called the extreme angle.The importance of brazing holding time
