Movement diagram of jaw crusher mechanism

1. There are no compound hinges, no local degrees of freedom and no virtual constraints in the motion diagram of this mechanism
there are 5 free members, 7 low pairs and 0 high pairs in this mechanism< So the degree of freedom f = 3n-2pl-ph = 3 * 5-2 * 7-0 = 1

2. What about the manual?

3. The difference between mechanism diagram and mechanism motion diagram is that mechanism motion diagram must be drawn according to scale. The mechanism diagram is not drawn on a scale
mechanism schematic diagram is to show the structural condition of the machine, and it can also be drawn without strict scale, which is usually called mechanism schematic diagram
mechanism motion diagram: it is a simple graph that uses the specified simple lines and symbols to represent the components and motion pairs, determines the position of the motion pairs according to the scale, and accurately expresses the motion characteristics of the mechanism. The mechanism motion diagram must be drawn according to the scale, otherwise it can only be called mechanism diagram. The scale of mechanism motion diagram is that the physical dimension (m) is larger than the drawing dimension (mm), and the unit is m / mm. The scale of mechanical drawing is that the drawing dimension (mm) is larger than the physical dimension (mm), and there is no unit.

Degree of freedom calculation:

there is no compound hinge, no local degree of freedom and no virtual constraint in the motion diagram of this mechanism

There are four free members, four low pairs and one high pair in this mechanism

so degree of freedom f = 3n-2pl-ph = 3 * 3-2 * 4 = 3
