Double-shaft type internal combustion engine power transmission and output mechanism

Abstract

The invention discloses a power transmission and output mechanism of a twin-shaft gas engine, which comprises a machine body; at least two power cylinders are arranged on the machine body; the piston rod ends of the power cylinders are connected with a connecting rod; the rod drive is provided with a gear crank arranged on the machine body; the gear crank is provided with a driving wheel; the machine body and an extra machine seat are also provided with an output shaft which is a straight shaft; the straight shaft is closely sheathed with at least two driven wheels which correspondingly matchwith each power cylinder; the driven wheels and the corresponding driving wheels are in transmission connection. The power transmission and output mechanism of the invention adopts the independent gear crank structure which matches with the power cylinders, which changes the mode that the original same gear crank is connected with a plurality of power cylinder; the structure can effectively reduce the resonance and torsional vibration of gear crank, and improve the service life of the whole machine; a single and independent gear crank is adopted, which has a convenient manufacturing method with low technical requirement; at the same time, the independent gear crank structure can effectively reduce torsional load with good stability, and when a single gear is worn, the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a double-shaft internal combustion engine power transmission and output mechanism, which is suitable for the wide use of medium and low speed internal combustion engines. Background technique [0002] The internal combustion engine power transmission and output mechanism generally adopts a crankshaft mechanism, which receives power through the piston, transmits it to the crankshaft through the connecting rod, and transmits the power from the crankshaft. The crankshaft is generally an integral type on medium and high-speed internal combustion engines, and can be segmented on low-speed internal combustion engines. No matter what kind of structure it is, the crankshaft is an integral structure when it is running. power. [0003] According to the current situation of use, the disadvantages of this type of structure are: 1. It is difficult to manufacture, forge an...

Problems solved by technology

[0003] According to the current situation of use, the disadvantages of this type of structure are: 1. It is difficult to manufacture, forge and process large crankshafts; 2. When the power generated by one cylinder passes through the cranks of other cylinders, the cranks will be subjected to twisting force and twist Deformation; 3. Because each cylinder transmits power to a crankshaft, resonance and torsional vibration are prone to occur; 4. Due to the limitation of the cylinder bore and the space when the connecting rod swings in the medium-speed internal combustion engine, it is difficult to increase the piston stroke
