Swing arm type power machine

Abstract

The invention belongs to the technical field of power machines and relates to a swing arm type power machine. The swing arm type power machine is characterized in that the power output by a power device is used by a first transmission to drive a crankshaft to rotate; more than three crank arms of the crankshaft, which are uniformly distributed in the circumferential direction, are respectively hinged with two connecting rods; one connecting rod and the other connecting rod on each crank arm form two connecting rod groups; the other end of the connecting rods in each connecting rod group is respectively symmetrically hinged with long lever ends of two lever groups which are vertically arranged at the two sides of the crankshaft; the other end of two groups of connecting rods, which is hinged with short lever ends of the two lever groups, is respectively hinged with more than three crank arms, which are uniformly distributed in the circumferential direction, of a second crankshaft and a third crankshaft and drives the crank arms to rotate; the second crankshaft and the third crankshaft respectively utilize the transmission to output mechanical work or drive own generator to generate power; and journals of the crankshafts and fulcrum shafts of the two lever groups are hinged on the shell or a frame. The power machine has the advantages of simple structure, low frictional resistance, less power consumption and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of power machines, in particular to a swing arm type power machine. Background technique [0002] At present, people utilize the labor-saving principle of lever power transmission in combination with crankshaft connecting rod to convert rotation into the power machine designed by the principle of swing. There are many technical solutions. Connecting rods are arranged at both ends of the unbalanced lever, and below the connecting rods are crankshafts set at an included angle. The disadvantages are: first, the structure is complex and the production cost is high; second, the torque output by the labor-saving machine is unidirectionally biased. , force transmission is asymmetrical; third, all the levers of this type of power machine are set horizontally, and most of the gravity of the lever is borne by the connecting rods at both ends and the power device, which will consume power, and then consume energy. The ...

[0002] At present, people utilize the labor-saving principle of lever power transmission in combination with crankshaft connecting rod to convert rotation into the power machine designed by the principle of swing. There are many technical solutions. Connecting rods are arranged at both ends of the unbalanced lever, and below the connecting rods are crankshafts set at an included angle. The disadvantages are: first, the structure is complex and the production cost is high; second, the torque output by the labor-saving machine is set in one direction. , the force transmission is asymmetrical; third, all the levers of this type of power machine are set horizontally, and most of the gravity of the lever is borne by the connecting rods at both ends and the power device, which will consume power, and then consume energy. The efficiency is low and cannot be marketed. accepted
