Description
Technical field
The present invention relates to a kind of equal load system, more particularly to planetary mechanism equal load system.
Background technology
Vibration is easily produced when load skewness is more serious in planetary transmission system, increases noise, or even wheel
Tooth fractures, and so as to shorten its service life, therefore, the improvement of load distribution inhomogeneities is asking of must take into consideration between planetary gear
Topic.Particularly when planetary gear quantity is more than three, then planetary gear is more easy to that unbalance loading phenomenon occurs.The unbalanced reason master of load distribution
Have:First, inevitable error in manufacture and assembling.Error is roughly divided into gear foozle in itself and planet carrier, case
Composition error two parts of the manufactures such as body, bearing assembling.Due to requiring that sun gear often keeps equal with several uniform planetary gears
Weighing apparatus engagement, to gear movement precision, such as gear ring circular runout deviation, base pitch deviation, teeth directional deviation and the requirement of tooth form deviation compared with
It is high.The manufactures such as planet carrier, casing and bearing assembling composition error be mainly the angular deviation of several planetary gear axis holes on planet carrier,
Central moment deviation, its overall target be adjacent holes away from error, be structure in addition with the such as the coaxiality deviation of individual basic building block bis-
Part caused harmful elastic deformation under load effect, such as center sun gear torsional deflection tri- is due to inertia force, frictional force
These errors of error Deng caused by will make between centre wheel gear teeth work flank profil or centre wheel when being engaged with planetary gear generation interference or
Gap, the load distribution destroyed between planetary gear and the uniformity along engagement facewidth load distribution.Furtherly, the load on planetary gear
Can lotus depend on the operational delay of planetary gear and reach preferable position in reasonable time, it is therefore desirable to which one kind is used for planet
The equal load system of mechanism, the back lash between each gear is eliminated, avoid planetary gear operational delay.
The content of the invention
In view of this, it is an object of the invention to provide a kind of planetary mechanism equal load system, can eliminate each in planetary mechanism
Back lash between gear, avoid planetary gear operational delay.
The planetary mechanism equal load system of the present invention, including be connected in planetary mechanism between each planetary gear and be used for together
Realize the synchronous load balancing mechanism carried in the planetary position of successive step；
Further, the synchronous load balancing mechanism includes balance element and connecting rod；The balance element is rotationally connected with planetary mechanism；
The connecting rod corresponds to each planetary gear sets and is articulated with formation crank rocker machine between balance element and corresponding planetary gear
Structure；
Further, equal synchronous axial system between each planetary gear and respective wheel shaft in planetary mechanism；The connecting rod passes through institute
Wheel shaft is stated to be connected in corresponding planetary gear；
Further, the wheel shaft is eccentric shaft；
Further, the coaxial single-degree-of-freedom of the balance element is rotationally connected with the sun gear of planetary mechanism.
The beneficial effects of the invention are as follows：The planetary mechanism equal load system of the present invention, adjustment planetary gear and ring gear and the sun
Synchronous load balancing mechanism is loaded onto after wheel fully engagement, makes each planetary gear synchronous axial system, and then keeps each planetary gear and ring gear
And fully engaged between sun gear, the back lash between each gear in planetary mechanism is eliminated, avoids planetary gear operational delay.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Fig. 1 is the structural representation of the present invention, as shown in the figure：The planetary mechanism equal load system of the present embodiment, including transmission
It is connected to and is used for the equal carrier aircraft of synchronization that the planetary position realization of synchronous adjustment carries in planetary mechanism between each planetary gear 1
Structure；Due to the influence of machining accuracy, certain fit clearance between planetary gear 1 and sun gear 2 and ring gear 6 be present, adjust
After the corner of planetary gear 1 eliminates above-mentioned gap, between synchronous load balancing mechanism is connected into each planetary gear 1, make each planetary gear 1
Between produce mutually constraint, realize the synchronous axial system of each planetary gear 1, avoid the operational delay of planetary gear 1.
In the present embodiment, the synchronous load balancing mechanism includes balance element 3 and connecting rod 4；The balance element 3 is rotationally connected with row
Star mechanism；The connecting rod 4 is corresponded to set and be articulated between balance element 3 and corresponding planetary gear 1 to each planetary gear 1 and formed
Crank and rocker mechanism；Planetary gear 1 rotates the crank for forming crank and rocker mechanism, and balance element 3 back and forth reverses and forms crank rocker machine
The rocking bar of structure, each connecting rod 4 shares a balance element 3, therefore each connecting rod 4 can produce linkage, same step in the presence of balance element 3
Whole planetary position, which is realized, to be carried, and the sun gear 2 of balance element 3 and planetary mechanism is coaxially disposed, can be by the company of rotation of balance element 3
Sun gear 2, planet carrier or ring gear 6 are connected to, connecting rod 4 and balance element 3 adapt to installing space narrow and small in planetary mechanism, structure
It is compact, convenient to carry out, the synchronous load balancing mechanism can be mounted directly on existing planetary mechanism, beneficial to popularization and application.
In the present embodiment, equal synchronous axial system between each planetary gear 1 and respective wheel shaft 5 in planetary mechanism；The connecting rod 4
Be connected by the wheel shaft 5 in corresponding planetary gear 1, between connecting rod 4 and wheel shaft 5 can setting-up eccentricity bearing, make 5 turns of wheel shaft
Drivening rod 4 moves in the form of bent axle when dynamic, compact-sized, convenient to carry out.
In the present embodiment, the wheel shaft 5 is eccentric shaft, and wheel shaft 5 can be transported drivening rod 4 when rotating in the form of bent axle
It is dynamic, the installation being easy between connecting rod 4 and wheel shaft 5.
In the present embodiment, the 3 coaxial single-degree-of-freedom of balance element is rotationally connected with the sun gear 2 of planetary mechanism, and structure is steady
It is qualitative good.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
