  • Mechanical principle: parallelogram mechanism

    introduction:Each member is a parallelogram plane connecting rod mechanism。It is a hinged four-bar mechanism﹐According to the condition of the crank, it belongs to the double crank mechanism(See picture Parallelogram mechanism )。 When the four rods of the parallelogram mechanism are in a straight line position﹐The motion of the follower is uncertain﹐In order to avoid this phenomenon﹐A parallel bar is often added to the parallelogram mechanism(In the picturea Parallelogram mechanism as above )。One of the characteristics of this mechanism is that the relative rods are always parallel﹐And the angular displacement of the two connecting rods﹑Angular velocity and angular acceleration are always the same﹐Such as locomotive wheel drive mechanism(In the pictureb Parallelogram mechanism Such as
