It is even loaded, severely impact the performance of its power dividing type structural advantages.This is why at present in production, to relatively high power
Three-ring speed reducer, driving motor can only use 750 revs/min of slowspeed machine, this just significantly increases the cost of motor.How
Three-ring gear reducer is carried, reduces vibration, reduce noise, has three-ring gear reducer and balances unit as high speed, height
Condition, extending its application field becomes a technical problem of industry.
In view of this, how to solve the load of three-ring gear reducer, carrying out vibration and noise reducing to three-ring gear reducer is skill in industry
One project of art personnel's urgent need to resolve.
The object of the present invention is to provide the three-ring gear reducers that a kind of band carries ring, are not dramatically increasing three-ring gear reducer
Under the premise of volume and weight, while is improved by the deficiencies in the prior art, is only existed also without change for the thematic structure of three-ring gear reducer
The adaptive change that input shaft, the bearing supported end of output shaft and three internal tooth ring plate bearing installations are installed, by
Increase between bearing and bearing block load ring, rigid connection is become floating connection, can by carry ring flexible deformation and
Rotatable characteristic, come realize act on each axis of speed reducer, the inertia force on each internal tooth ring plate supporting-point reduces while effectively subtracting
Small inertia couple；Also it can use this to carry ring realization counteracting or reduce the brings such as foozle, rigging error imbalance
The moment of inertia makes three-ring gear reducer be intended to complete equipilibrium, achievees the purpose that carry vibration damping, eliminates the main contributor for causing vibration,
To which the three-ring gear reducer for making band carry ring has as high speed, the high condition for balancing unit.
The embodiment of the present invention is achieved in that
The embodiment provides the three-ring gear reducer that a kind of band carries ring, the structure main feature of load ring includes circle
Ring base skeleton, outer lug boss and inner convex platform, outer lug boss and inner convex platform are evenly arranged on the outside and inside of annulus matrix skeleton, and evagination
Platform and inner convex platform position are interlaced uniformly distributed.
Specifically, installed in input shaft, the bearing supported end of output shaft and three internal tooth ring plate bearing installations
Adaptive change carries ring by increasing between bearing and bearing block, rigid connection is become floating connection, can be by equal
The flexible deformation of ring and rotatable characteristic are carried, each axis will be applied to, the out-of-balance force on each internal tooth ring plate or torque are supporting
It is transmitted at point by bearing, is reduced or be completely counterbalanced by using the flexible deformation of itself.It can be turned using damping elastomer ring is carried
Dynamic characteristic, can be to avoid concentrated wear, while fatigue strength with higher.Band carries the three-ring gear reducer of ring compared to not
Band carries the three-ring gear reducer unbalance inertia force of ring and torque and will effectively reduce, and load is more uniform, will reduce in root
The vibratory impulse of three-ring gear reducer, while noise level is reduced, three-ring gear reducer can be made to reach very high revolving speed requirement.
Optionally, carry ring have technique fillet, between outer lug boss and matrix skeleton be equipped with outer lug boss fillet R1, inner convex platform with
Inner convex platform fillet R2 is equipped between matrix skeleton.
Optionally, it carries ring and selects the materials such as stainless steel, 65Mn.
Optionally, the edge for carrying ring is provided with rounded corner.
Optionally, carrying ring allows that the damping elastomer band provided by the invention that carries can be used and roll there are an interface

Optionally, if the width for carrying ring is less than bearing width, several wide or not wide load ring can be used
Width phase Calais adapts to bearing width.
Optionally, carrying ring can be used lubricating oil or grease lubrication, preferably lubricating oil.
Compared with prior art, the beneficial effect of the embodiment of the present invention is:
In conclusion the band carries the three-ring gear reducer of ring under the premise of micro increase volume and weight, while to main body knot
Structure is without change, the adaptation only installed in input shaft, the bearing supported end of output shaft and three internal tooth ring plate bearing installations
It sexually revises, carries ring by increasing between bearing and bearing block, rigid connection is become floating connection, can substantially reduce bearing
The inertia force and torque at place, reduce the vibratory impulse of three-ring gear reducer from the root, while reducing noise level, and band carries ring
Three-ring gear reducer can achieve very high revolving speed requirement.
