Description
Technical field
The utility model belongs to Mechanical Driven equipment technical field, and in particular to a kind of structure is simple, mechanical efficiency is high
Lever crankshaft connecting rod system.
Background technique
The power source and crankshaft center of traditional crankshaft-link rod kind of drive are nearly on straight line, power source
One stroke of every operation, then synchronous driving crankshaft completes a circle rotation movement to connecting rod, to improve the speed of rotation of crankshaft,
It is then the length taken increase between axis and connecting rod neck to realize, it is faster also to create crankshaft rotation speed, stroke
The case where must just increasing；On the other hand, the stroke of traditional crankshaft-link rod transmission is synchronous reciprocating, i.e. power source
A reciprocating stroke is done, crankshaft also does a circle rotation movement therewith, then, it is lost in power source in operational process
Power it is too many, cause efficiency of energy utilization low, vast resources caused to waste, the maximum rotative speed of crankshaft is still limited
System.
Therefore, developing a kind of new, the high transmission of crankshaft link mechanism of mechanical efficiency is the key that solve the problems, such as.
Utility model content
The lever crankshaft connecting rod system that the purpose of this utility model is to provide a kind of structures is simple, mechanical efficiency is high.
Purpose of the utility model is realized as follows: including crankshaft, and the drive link being connect with the connecting rod neck of crankshaft,
The drive link includes driving lever, drive rod and connecting rod rack, and the upper end of the driving lever connects power source, and lower end connection is driven
Lever, the middle and lower part of the driving lever and connecting rod rack, which are movably hinged, to be arranged, and connecting rod rack is then set to the crankshaft bracket of crankshaft
On, so that driving lever is moved reciprocatingly in vertical direction with connecting rod rack support, the lower end of the drive rod and the company of crankshaft
Bar neck is movably hinged setting, and drive rod drives crankshaft rotation.
The utility model structure is simple, runs smoothly, in the premise for not increasing the length between axis and connecting rod neck
Under, power source can be realized within the time for doing a reciprocating stroke, crankshaft can at least do two circle rotation movements,
Make the directly proportional increase of compression ratio, strength and the revolving speed of power source, greatly reduces the power that power source is lost in operational process, mention
High-energy source utilization efficiency avoids a large amount of power resources from wasting, makes the rotation of connecting rod significant increase crankshaft in limited stroke range
Rotational speed rate；Improve the mechanical efficiency of power source and crankshaft.

Specific embodiment
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation is transformed or replaced based on any made by the utility model introduction, belongs to the protection scope of the utility model.
The lever crankshaft drive link mechanism as shown in attached drawing 1 ~ 5, including crankshaft 1, and connect with the connecting rod neck of crankshaft 1
The drive link connect, the drive link include driving lever 4, drive rod 6 and connecting rod rack 7, the upper end connection of the driving lever 4
Power source 3, lower end connect drive rod 6, and the middle and lower part of the driving lever 4 and connecting rod rack 7, which are movably hinged, to be arranged, connecting rod rack 7
It is then set on the crankshaft bracket 2 of crankshaft 1, driving lever 4 is made to move reciprocatingly in vertical direction with the support of connecting rod rack 7,
The lower end of the drive rod 6 and the connecting rod neck of crankshaft 1 are movably hinged and are arranged, and drive rod 6 drives crankshaft 1 to rotate.
Distance of the hinge hole 5 apart from 4 bottom end of driving lever is not more than the length of drive rod 6, and is not less than drive rod 6
Half times length.
The length ratio of the driving lever 4 and drive rod 6 is not less than 2:1.
The driving lever 4 is 0 ~ 160 degree in the reciprocating motion range of vertical direction.
The hinge hole 5 with the dynamic cooperation of connecting rod rack 7 is provided on the driving lever 4.
The hinge hole 5 and driving lever 4, which is integrally formed, to be arranged.
The driving lever 4 and power source 3, which is movably hinged, to be arranged.
The driving lever 4 and drive rod 6, which is movably hinged, to be arranged.
Utility model works principle and the course of work: power source 3 drives driving lever 4 to do the reciprocating motion in vertical direction
In the process, when 4 stress of driving lever is first that support rotates down in vertical direction with connecting rod rack 7, driving lever 4 turns downwards
Drive rod 6 is pushed to rotate a circle during dynamic, and drive rod 6 is then with 1 synchronous rotary of dynamic crankshaft one week；When downward movement travel
When moving reset in end, it is rotated up in vertical direction with connecting rod rack 7 for support after 4 stress of driving lever, driving lever 4 exists
Drive rod 6 is pushed to rotate a circle during being rotated up, and drive rod 6 is then with 1 synchronous rotary of dynamic crankshaft one week；Make power source 3
Within the time that operation finishes a stroke, driving lever 4 has done two circular motion with dynamic crankshaft 1, greatly improves power source 3
Drive efficiency and quality.
