Crank slider mechanism of jaw crusher

1. It basically consists of an organic frame, a crank, a connecting rod and a sliding block. For example: the case of internal combustion engine is frame, crankshaft is crank, connecting rod is connecting rod, piston is slider. The function is to convert the linear motion of the piston driven by the pressure generated by the air after combustion into rotary motion, and the engine turns. Take the air compressor for example: the casing is the frame, the crankshaft is the crank, the connecting rod is the connecting rod, and the piston is the slider. Its function is to convert the rotary motion into linear motion and compress the air.

In the engine, gasoline and air are mixed into combustible gas in the carburetor, which is input into the engine cylinder and compressed, and then ignited by electric spark to generate heat and work

2, four stroke engine: every working cycle (intake, compression, power, exhaust), crankshaft rotation 2 cycles (720 °

The highest position of piston is called top dead center (TDC)

The lowest position of piston is called bottom dead center (BDC)

The distance s between the top and bottom dead center is called the piston stroke, and the distance r between the connecting center of the crankshaft and the lower end of the connecting rod and the crankshaft center is called the crank radius; For engines where the cylinder centerline passes through the crankshaft centerline, the piston stroke s is equal to twice the crank radius R

3. Jaw crusher is a motor driven jaw plate, the dynamic jaw and static jaw squeeze each other to crush the raw materials

Crank slider mechanism is a planar linkage mechanism which uses crank and slider to realize the conversion of rotation and movement. In the crank slider mechanism, the slider is the component of the moving pair formed with the frame, and the component connecting the crank and the slider through the rotating pair is the connecting rod. It is evolved from the crank rocker mechanism in the hinged four-bar mechanism

widely used in spraying equipment, CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automobiles, medical devices, printing machinery, packaging machinery, woodworking machinery, mold opening and many other fields

extended data:

maximum speed position of slider:

according to the ratio of maximum speed and average speed of slider working stroke, the first problem is to determine the maximum speed position of slider working stroke

this paper discusses the position of the maximum speed of the slider in different types of crank slider mechanisms, and draws a conclusion: for offset crank slider mechanism, the maximum speed of the slider appears at the place where the crank and the connecting rod are perpendicular to each other; Generally, the maximum speed of the slider does not appear at the place where the crank and the connecting rod are perpendicular to each other. With the increase of the length ratio of the connecting rod, the slider is closer to 90 at the maximum speed °

when crank slider mechanism and other mechanisms, such as rack and pinion mechanism, cam mechanism, etc. are connected in series to form a composite mechanism, so as to realize a certain function, the ratio of the maximum speed of slider working stroke to the average speed of working stroke is often used δ =υ C max / υ Therefore, it is very important to understand the maximum speed position of the slider working stroke for the design of the mechanism

through the calculation model of crank slider mechanism, the movement law of slider is obtained, and the equation operation of Excel is used to avoid the difficulty of finding the extreme value of complex function, and the Excel method is simple, fast and accurate, which fully meets the requirements of engineering design

It is helpful for designers to understand the motion characteristics of slider crank mechanism and determine the design parameters according to the requirements of engineering practice, such as γ、λ It makes designers less detours and improves design efficiency, which has important guiding significance for the design of linkage mechanism

6. Crank slider mechanism is a kind of mechanism which is formed by connecting crank, connecting rod and piston through hinge. It is evolved from crank rocker mechanism in hinge four-bar mechanism!

7. Crank slider mechanism is evolved from crank connecting rod mechanism.

8. The crank slider and the cutting part of the shaping machine can be regarded as the crank doing the whole circle motion, and the slider doing the reciprocating linear motion. The difference is that the cutting part of the shaping machine has the characteristics of quick return in order to improve the work efficiency.
