Embodiment 2
The four-bar linkage being rocking bar with reference to accompanying drawing 5,7,8,9: two side link is called double rocker mechanism.Usual drive crank at the uniform velocity swings, and driven rocking bar speed change swings.Double rocker mechanism is only suitable for low speed occasion.Aircraft takeoffs and landings frame mechanism is typical double rocker mechanism.Through appropriate design, double rocker mechanism also can be used to realize some and specifically moves.Such as crane formula crane can realize the approximate straight line motion of fishhook, makes not do during moving heavy object or do work less thus reduce energy consumption.And for example vehicle steering mechanism: Ackermann steer angle, if two front-wheel axis and trailing wheel axis whenever can be made to intersect at the center of circle of bend, then four wheels is all relative to ground pure rolling, and tire would not damage because of slip, and obviously this just requires the corner of two-wheeled.The isometric double rocker mechanism (being called tie rod linkage) of two rocking bars just can meet this requirement approx.Various four-bar mechanism all from hinge four-bar develop, understanding four-bar mechanism evolution, to analysis of mechanism and mechanics innovation helpful.In four-bar linkage, get different component and make the four-bar mechanism that frame can be evolved into different types.
Embodiment 3
With reference to accompanying drawing 6,10,11,12: in crank and rocker mechanism as shown in the figure, when crank 1 rotates around axle A, hinge C is by reciprocally swinging.If rocking bar 3 is made slide block form, and make it move back and forth along guide rail, obviously its kinetic property does not change; But now four-bar linkage has been evolved into the slider-crank mechanism of curvilinear guide.So four-bar linkage will become common slider-crank mechanism.Brace Turning Center, to the distance e of slide block guide passage, is called offset distance, if e=0, is referred to as centric slider-crank mechanism; If e ≠ 0, be referred to as Offset slider-crank mechanism.If the length of component AB is 11, the length of component BC is l2, then ensure that the condition that bar AB bar becomes crank is: l1+e≤l2.Slider-crank mechanism is changed for the motion between rotating and moving back and forth, and is widely used in the plant equipment such as internal combustion engine, air compressor, punch press and autoloader.In slider-crank mechanism, if get different component as frame, then this mechanism will be evolved into and determine block mechanism, cranking block mechanism or guide-bar mechanism etc.The evolution a crank and rocker mechanism of Fig. 8 four-bar mechanism; B slider-crank mechanism; C guide-bar mechanism 2 determines block mechanism in slider-crank mechanism shown in figure, if using slide block as frame, then slider-crank mechanism is just evolved into and determines block mechanism.3 cranking block mechanisms, if get 2 as shown in the figure in slider-crank mechanism for fixed component, then can obtain cranking block mechanism, this mechanism is widely used in fluid pressure drive device.4 guide-bar mechanisms are as shown in the figure in slider-crank mechanism, if get component 1 as frame, then slider-crank mechanism is just evolved into guide-bar mechanism.In mechanism, component 4 is called guide rod, and slide block 3 relatively guide rod slides, and rotates around A point together with guide rod, and generally getting connecting rod 2 is driving link.As l1 < l2, component 2 and component 4 can do circumferential rotation type, and this mechanism is called whitworth mechanism.As l1 > l2, component 2 can do circumferential rotation type, and component 4 can only swing in a certain angle, then this mechanism becomes oscillating guidebar mechanism.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
