Description
Technical field
The present invention relates to a kind of engine, especially a kind of balance system of engine.
Background technique
Currently, in reciprocating mechanism, especially within the engine, the main reason for causing engine luggine is piston
The power for moving back and forth and generating cannot be fully balanced；During crankshaft rotates every time, piston is started and stopped twice, makes piston
The reaction force for the power for accelerating and slowing down is transmitted on the body of engine by crankshaft, so that engine generates periodically vibration
It is dynamic, along with being continuously increased for engine power demand, cause piston weight and piston speed to increase, the amplitude of vibration is increasingly
Greatly, this vibration passes to operator by the terminal device connecting with body, and operator is caused not feel good or can not receive.
Especially sent out in the more demanding driving equipment field of comfort, in the more demanding compressor equipment field of vibration, in aviation
Motivation field etc., this vibration frequently can lead to engine or associated equipment is damaged and service life reduction, sends out when serious
Raw major accident.
In order to reduce vibration, existing many engines reduce the vibration by additional rotation or reciprocating mass
It is dynamic.In the patents of invention such as CN1243188C, CN100351506, CN101910674A, balancing device or balance system are meeting
One order inertia power can be balanced under specified conditions, still, do not referred to how to eliminate second order and high frequent vibration.Real engine
There is also second orders and Higher-order inertia link power in vibration, although the vibration acceleration of second order and high-order has substantially compared with single order vibration acceleration
Reduce, but still causes the judder of engine, and the vibration frequency of second order and high-order consolidating closer to application terminal
Have frequency, it is easy to cause the resonance of terminal, the generation of covibration will aggravate to vibrate significantly, influence associated member intensity and
The experience sense of operator is by only eliminating one order inertia power can no longer meet current application scenarios demand.
The application for a patent for invention file of entitled " a kind of balance system of engine " is disclosed in CN108533402A, it
Including engine body component, it is characterized in that: at least two slider-crank mechanisms are provided in the engine body component,
One of slider-crank mechanism is oppositely arranged with another slider-crank mechanism；It is sliding in one of slider-crank mechanism
The velocity and acceleration of block movement is similar to the velocity and acceleration feature of slide block movement in another slider-crank mechanism.Although
The balance system of engine of the structure can effectively eliminate the single order, second order and high frequent vibration generated in engine operation process, but
It is, since use guide post mechanism is oriented to, so that it is not can guarantee slider-crank mechanism during guiding and move along a straight line,
It is unable to reach the expected effect for eliminating vibration.
Summary of the invention
That engine that slider-crank mechanism moves along a straight line can be effectively ensured is flat it is an object of the invention to provide a kind of
Balance system.
It is realized the purpose of the present invention is technical solution in this way, a kind of balance system of engine, including has case
The engine housing of lid, is provided at least two slider-crank mechanisms being oppositely arranged in the engine case body, it is described its
In one end of a slider-crank mechanism crank and same crankshaft are passed through by one end of crank and another slider-crank mechanism
Connection, the both ends of one of slider-crank mechanism pass through guiding mechanism respectively and connect with case lid and engine housing.
Wherein, one of slider-crank mechanism includes piston group 2 and connecting rod assembly 3；Another described slide crank
Block mechanism includes balance weight 4, slave connecting rod A5 and slave connecting rod B6；The piston group 2 is connected by connecting rod assembly 3 and crank and crankshaft 8
It connects；The both ends of the balance weight 4 pass through slave connecting rod A5 respectively and slave connecting rod B6 is connect with crankshaft 8；The slave connecting rod A5 and pair are even
Bar B6 is located at the two sides of connecting rod assembly 3；The balance weight both ends pass through guiding mechanism and cover wall and engine respectively
Cabinet wall connection.
In the present invention, further guiding mechanism is described, the guiding mechanism includes being arranged at balance weight both ends
And the guide rail A and guide rail B being wholely set with balancing patch, and the sliding slot A being arranged on cover wall and setting are in engine case
Sliding slot B, the guide rail A and guide rail B on internal wall are located in sliding slot A and sliding slot B and slide up and down.
For the ease of connection, balance weight is connect in this way with slave connecting rod A and slave connecting rod B, and the guide rail A and guide rail B are logical
Cross connecting pin respectively with the lower end slave connecting rod A and the lower end slave connecting rod B.
Further, guiding mechanism is it is also possible that setting: the guiding mechanism include setting balance weight both ends and with it is flat
