Abstract
The utility model relates to an advancing crankshaft, which is suitable for dynamic force machines whose crankshafts are used as transmission shafts like internal-combustion engines, etc. The path (namely the connecting plate) from a crankshaft arm to a crankshaft core is designed to a curved shape with included angle of 90 DEG, and the distance from the axle core of the crankshaft arm to a bending point is equal to the distance from crankshaft core to the bending point. The elbow-shaped tip of the crankshaft connecting plate is positioned at an advancing 45 DEG position when the crankshaft and the piston connecting rod of the internal-combustion engines are positioned at a collinear dead point position, and the crankshaft arm can form continuous rotation across the dead point by inertia. The utility model can enhance transmission efficiency and reduce fuel consumption.
Description
The utility model relates to the bent axle structure of the connecting rod in the mechanical transmission, and the machine that is suitable for internal-combustion engine etc. and with the bent axle is transmission shaft uses, and belongs to the dynamic power machine field.
In mechanical transmission, many dynamic power machines use connecting rod or slidercrank mechanism work, when crank up one during week, crank is at two positions and connecting rod conllinear, when crank is Passive part, in Der Grundsatz der Maschinen, this collinear position is called upper and lower stop (or dead point) position, and this moment, crank may not rotate or backward rotation, in order to cross stop transmission was able to continuously, have to take to set up measures such as flywheel, increased the power consumption of machine.
The purpose of this utility model provides a kind of bent axle of novel structure, makes it cross stop easily, reduces energy consumption, the fuel oil utility ratio of power machines such as raising internal-combustion engine, and the output that improves power when expansion space stroke reduces the consumption of function when compression stroke.
Used technological scheme, Advancing crankshaft of the present utility model is made of the crank arm and the bent axle heart, and its major character is: crank arm is that connecting plate is crooked to the approach of the bent axle heart, and angle is 90 °.And crank arm axle center to the distance of bending point equates with the distance of the bent axle heart to bending point.
Advancing crankshaft of the present utility model has following good effect: make the elbow bent tip of crankshaft web point to gyratory directions during assembling, when bent axle and connecting rod or slide block (that is piston of internal-combustion engine) when being in the dead-centre position of conllinear, the elbow tip of crankshaft web has been in leading 46 ° position, its inertia is enough to make crank to cross stop, form continuously and rotate, this is the most significant structure characteristic of Advancing crankshaft and effect.The internal-combustion engine of assembling Advancing crankshaft can make transmission efficiency improve, and petrol engine efficient reaches 30-40%, and Efficiency of Diesel Engine reaches 40-50%.
Now in conjunction with the accompanying drawings:
Fig. 1 is the schematic representation of bent axle structure of the present utility model, is front view.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Advancing crankshaft is made of crank arm 1, the bent axle heart 2 and sees that Fig. 1 to Fig. 3, crank arm 1 are that connecting plate 3 is crooked to the approach of the bent axle heart 2, its angle is 90 °, and the axle center 4 of crank arm 1 to the distance of bending point 6 equates that with the distance of the bent axle heart 6 to bending point 5 its line of centers 4-5 is vertical mutually with line of centers 6-5.
Claims (2)
1. an Advancing crankshaft is made up of the crank arm and the bent axle heart, it is characterized in that: crank arm is that connecting plate is crooked to the approach of the bent axle heart, and its angle is 90 °.
2. Advancing crankshaft according to claim 1 is characterized in that: crank arm axle center to the distance of bending point equates with the distance of the bent axle heart to bending point, and vertical mutually.
