Problems solved by technology

Although the engine balance system of this structure can effectively eliminate the first-order, second-order and higher-order vibrations generated during the operation of the engine, due to the use of the guide post mechanism for guidance, it cannot ensure that the crank slider mechanism is in a straight line during the guidance process. Movement, unable to achieve the expected effect of eliminating vibration

Embodiment 1

[0019] Embodiment 1: as figure 1 , 2 As shown in , 3, a kind of engine balance system, comprises the engine box body 2 that has box cover 1, is provided with at least two oppositely arranged crank-slider mechanisms in described engine box body 2, and one of the crank-slider mechanisms One end of the block mechanism is connected with the same crankshaft 8 through the crank 9 and one end of the other crank-slider mechanism is connected with the same crankshaft 8 through the crank 9, and the two ends of one of the crank-slider mechanisms are respectively connected with the case cover 1 and the engine case 2 through the guide mechanism .

[0020] Wherein, one of the slider crank mechanisms includes a piston group 3 and a connecting rod assembly 4; the other slider crank mechanism includes a balance weight 5, an auxiliary connecting rod A6 and an auxiliary connecting rod B7; The rod assembly 4 and the crank 9 are connected to the crankshaft 8; the two ends of the balance weight 5...

Embodiment 2

[0024] Embodiment 2: as Figure 4 As shown, the guide mechanism includes a chute mechanism A and a chute mechanism B arranged at both ends of the balance weight 5 and integrated with the balance sheet 5, and a guide rail that is arranged on the inner wall of the box cover 1 and cooperates with the chute mechanism A. C15 and the guide rail D16 that is arranged on the inner wall of the engine case 2 and cooperates with the chute mechanism B.

[0025] Wherein, the chute mechanism A includes chute C17 and chute D18 arranged on both sides of one end of the balance weight 5, and chute E19 and chute F20 arranged on both sides of the other end of the balance weight 5, so The guide rail C15 is clamped on the chute C17 and the chute D18, and the guide rail D16 is clamped on the chute E19 and the chute F20.

Abstract

The invention discloses an engine balance system. The engine balance system comprises an engine box body (2) provided with a box cover (1); at least two slider-crank mechanisms arranged oppositely arearranged inside the engine box body (2); one end of one slider-crank mechanism, together with one end of the other slider-crank mechanism, is connected with the same crankshaft (8) through a crank (9); and the two ends of one slider-crank mechanism are each connected with the engine box body (2) through a guide mechanism. The engine balance system disclosed by the invention has the advantages ofcompact structure, reliable use and low cost, can guarantee that the slider-crank mechanisms are in linear motion all the time so that first-order vibration, second-order vibration and high-order vibration generated in a running process of an engine can be effectively eliminated, improves the experience feeling of a user, also improves the performances of the engine and prolongs the service life of the engine.

Description

technical field [0001] The invention relates to an engine, in particular to an engine balancing system. Background technique [0002] At present, in reciprocating mechanisms, especially in engines, the main cause of engine vibration is that the force generated by the reciprocating motion of the piston cannot be completely balanced; during each rotation of the crankshaft, the piston starts and stops twice, making the piston The reaction force of the acceleration and deceleration force is transmitted to the engine body through the crankshaft, causing the engine to generate periodic vibration. With the continuous increase of engine power demand, the piston weight and piston speed increase, and the vibration amplitude becomes larger and larger. This vibration is transmitted to the operator through the terminal equipment connected to the body, causing the operator to feel uncomfortable or unacceptable. Especially in the field of driving equipment with high comfort requirements, ...
