Description
Technical field：
The utility model is related to the field of all use toggles, more particularly to is started using toggle
The balanced structure of machine.
Background technology：
In the working cycles of engine, the periodicity straight reciprocating motion of piston is converted into by toggle
The cycle rotary motion of bent axle.Due to the cyclic movement of reciprocating mass so as to which the periodicity produced along piston movement direction is used to
Property power.Inertia force passes to body by position of bearings causes body to produce periodic inertia force, here it is so-called start
Machine vibration.The size of this kind of vibration depends on the size and reciprocating acceleration magnitude of reciprocating mass.Toggle
Reciprocal inertia force can be approximately decomposed into superposition of several frequencies in the incremental power of multiple proportion.Frequency and past in superposed force
Multiple motion frequency identical power is referred to as one order inertia power, and frequency is referred to as second-order inertia power for the power of 2 times of reciprocating frequency, successively
Analogize.The balance shaft mechanism used at present can eliminate one order inertia power, but vibration can not still meet customer requirement, if
Second order power is further eliminated, mechanism will be more complicated, and often installing space is limited.
Utility model content：
The purpose of this utility model, which is to provide, a kind of can substantially eliminate the balance shaft structure of engine luggine, and structure
Optimization, spaces compact.
In order to achieve the above object, the utility model is realized in：A kind of balance shaft structure of engine, including song
Axle, the balance shaft gear being set on the bent axle, single order balance shaft, are installed with and the balance in the single order balance shaft
The single order balance gear that shaft gear is meshed, it is characterised in that：The second order for also including being meshed with the single order balance gear is put down
Weigh axis mechanism.Using above-mentioned balance shaft structure, the most vibration of engine can be further eliminated, reaches to basically reach and starts
The effect of machine itself dynamic balance, effectively reduction vibration.
Preferably, the second order balance shaft mechanism includes second order balance shaft one and second order balance shaft two, in the second order
The second order balance gear one being meshed with the single order balance gear is installed with balance shaft one, in the second order balance shaft two
It is installed with the second order balance gear two being meshed with the second order balance gear one.
In order to streamline organizations and realize compact conformation, the second order balance shaft one is located at described with the second order balance shaft two
The same side of single order balance shaft and balance gear intermeshing.
In order to ensure that single order balance shaft inertia resultant force frequency is identical with the one order inertia power frequency in reciprocal inertia force, direction
All the time on the contrary, the number of teeth of the single order balance gear is identical with the number of teeth of the balance shaft gear.
In order to ensure that second order balance shaft inertia resultant force frequency is identical with the one order inertia power frequency in reciprocal inertia force, direction
All the time on the contrary, the number of teeth of the second order balance gear two is identical with the number of teeth of the second order balance gear one, the second order balance
The number of teeth of gear one is the half of the number of teeth of the single order balance gear.
It is a kind of to include the engine of balance shaft structure described above.
Using the balance shaft structure of engine of the present utility model, the vibration of engine can be further eliminated, base is reached
The effect of this elimination engine luggine, and balance shaft structure of the present utility model is compact, occupies little space, and cost is low.
Brief description of the drawings：
Fig. 1 is the axonometric drawing of engine balance axle construction；
Fig. 2 is the top view of engine balance axle construction；
Fig. 3 is the axonometric drawing of engine balance axle construction（Band crankcase case lid）.
Embodiment：
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim scope claimed.
Embodiment：As Figure 1-3, a kind of balance shaft structure of engine, including bent axle 1, be set on the bent axle 1
Balance shaft gear 11, single order balance shaft 2, be installed with and be meshed with the balance shaft gear 11 in the single order balance shaft 2
Single order balance gear 21, in addition to the second order balance shaft mechanism being meshed with the single order balance gear 21.
Wherein, the second order balance shaft mechanism includes second order balance shaft one with 3 and second order balance shaft 24, in the second order
The second order balance gear 1 being meshed with the single order balance gear 21 is installed with balance shaft 1, in second order balance
The second order balance gear 2 41 being meshed with the second order balance gear 1 is installed with axle 24.
The number of teeth of the single order balance gear 21 is identical with the number of teeth of the balance shaft gear 11.The second order balance gear
2 41 number of teeth is identical with the number of teeth of the second order balance gear 1, and the number of teeth of the second order balance gear 1 is described one
The half of the number of teeth of rank balance gear 21.
In addition, the second order balance shaft 1 is located at the same of the single order balance shaft 2 with the second order balance shaft 2 41
Side.It is arranged at the side of the remote speed governing driven gear of the single order balance shaft 2.
Using the balance shaft structure of the engine of the present embodiment, in the course of work of engine, bent axle 1, which is rotated, to be driven admittedly
The balance shaft gear 11 being located at thereon is rotated, and balance shaft gear 11 is consistent with the rotation direction of bent axle 1, rotating speed is identical, the balance shaft tooth
Wheel 11 drives single order balance gear 21 fixed in single order balance shaft 2 to rotate, and then drives the single order balance shaft 2 to rotate, institute
State that single order balance shaft 2 is oppositely oriented with the bent axle 1, rotating speed is identical, the single order vibration of engine can be eliminated, engine is accounted for and shake
Dynamic 70%.The single order balance gear 21 drives the second order balance gear 1 to rotate, and then drives the second order balance shaft
One 3 rotate, and the second order balance gear 1 drives the second order balance gear 2 41 to rotate, and then drive the second order balance
Axle 24 is rotated.Therefore, the rotating speed of the second order balance shaft 1 is twice of single order balance shaft 2, and oppositely oriented, the second order
Rotating speed is identical between balance shaft 1 and the second order balance shaft 24, oppositely oriented.The second order vibration of engine can be eliminated, is accounted for
The 98% of engine luggine, reaches the effect for substantially eliminating engine luggine.
In addition, being separately provided for installing the single order balance shaft 2 and two on the crankcase and case lid of engine
The mounting hole of rank balance shaft mechanism.The single order balance shaft 2, second order balance shaft 1 and second order balance shaft 24 are arranged on bent axle
Between the casing and case lid of case, the space-consuming of balance shaft structure is reduced so that the structure of engine is compacter, and into
This is cheap, rationally distributed.
It is a kind of to include the engine of balance shaft structure described above.
