Description
Technical field
The utility model is related to precision machinery technology fields, and in particular to a kind of nested type rotary axis system.
Background technology
According to traditional shafting design method, shafting design is usually that bearing is arranged in axis both ends, in intermediate arrangement motor
Become with rotation, and have certain space interval between requiring motor and rotation to become, avoids influence of the motor-field to rotation varying magnetic field, from
And influence the angle measurement accuracy that rotation becomes, this shafting layout maximum the disadvantage is that the axial space occupied is big, the product of design
Weight also can and then increase, and the rotary inertia of equipment can also increase very much.
Therefore a kind of novel shafting of research and design is needed, utilizes radial space to greatest extent, reduce axial dimension, reduced
The weight and rotary inertia of tilting component, while electromagnetic shielding plate is designed, influence of the motor-field to rotation varying magnetic field is avoided, simultaneously
Reduce the weight and rotary inertia of tilting component.
Invention content
The technical problems to be solved in the utility model is in view of the foregoing defects the prior art has, to provide a kind of embedding
Shell type rotary axis system reduces axial dimension, reduces the weight and rotary inertia of equipment, avoids shadow of the motor-field to rotation varying magnetic field
It rings, provides the stability of equipment.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of nested type rotary axis system, including built-up shaft, rotation become rotor and rotor, rotor are sheathed on built-up shaft
On, rotation becomes rotor and is nested in rotor, and rotation, which becomes, is equipped with shielding case between rotor and rotor.
According to above-mentioned technical proposal, shielding case is electro-magnetic shielding cover.
According to above-mentioned technical proposal, the both ends of built-up shaft are equipped with bearing block, and bearing is equipped between bearing block and built-up shaft；
Bearing block positioned at both ends is respectively left shaft holder 1 and right axle bearing, and the bearing in left shaft holder 1 is left bearing, right axle bearing
Interior bearing is right bearing.
The utility model has the advantages that：
It is in the layout of in torque motor rotor inner hole by the way that change rotor nesting will be revolved, has greatly reduced rotor and rotation change turns
Son reduces orientation rotary inertia in axial layout dimension, has efficiently controlled localizer overall weight；Pass through motor
The separation shielding case that rotor and rotation become between rotor designs, and is effectively isolated the influence that motor-field becomes rotation electromagnetic type number, carries
The high stability of equipment, accumulates experience for the design of later similar structures, according to there is larger promotional value.
Description of the drawings
Fig. 1 is the structural schematic diagram of nested type rotary axis system in the utility model embodiment；
In figure, 1- left shaft holders, 2- left bearings, 3- built-up shafts, 4- rotation change rotors, 5- rotors, 6- electro-magnetic shielding covers,
7- right bearings, 8- right axle bearings.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
Shown in referring to Fig.1, nested type rotary axis system in a kind of embodiment provided by the utility model, including built-up shaft 3, rotation
Become rotor 4 and rotor 5, rotor 5 are sheathed on built-up shaft 3, rotation becomes rotor 4 and is nested in rotor 5, and rotation, which becomes, to be turned
Shielding case is equipped between son 4 and rotor 5.
Further, shielding case is electro-magnetic shielding cover 6.
Further, the both ends of built-up shaft 3 are equipped with bearing block, and bearing is equipped between bearing block and built-up shaft 3；Positioned at two
The bearing block at end is respectively left shaft holder 1 and right axle bearing 8, and the bearing in left shaft holder 1 is left bearing 2, in right axle bearing 8
Bearing is right bearing 7.
The operation principle of the utility model：
The general thought of the utility model design is to change former pitching shafting electromechanical compo serial arrangement form, using " embedding
The electromechanical compo parallel layout form of shell type ", this distribution form can greatly reduce axial dimension, while reduce equipment
Weight and rotary inertia, particular content are as follows：
1, the torque motor for selecting major diameter, compresses axial dimension in the case where providing identical torque；
2, rotation is become into nested layout in the rotor inner hole of torque motor, compression motor and rotation become in axial layout ruler
It is very little；
3, a shielding case is respectively devised beside motor and rotation become, effectively shields the magnetic field of motor, reduces motor
Influence of the magnetic field to rotating transformer angle measuring.
Using this layout designs, the axial dimension of pitching packet has been greatly reduced, not only can effectively reduce the weight of pitching packet
Amount；And orientation seat drives the rotary inertia when revolution of pitching packet also to substantially reduce, and torque and size can be selected relatively small
Azimuth-drive motor, therefore the weight of orientation seat also can further mitigate.
This innovation has been applied in product design, and function, performance are met the requirements.The innovation design has been adapted to stringent weight
It is required that one carry on the shoulder form photoelectricity localizer design, have larger promotional value.
The torque motor of the major diameter is reached with diameter, the smaller feature of width, in the case where ensureing torque, greatly
Axial dimension is had compressed greatly, reduces the width and rotary inertia of shafting, the arrangement for facilitating rotation to become；
The built-up shaft 3 is very big in the position radial space that motor assembles, and facilitates rotation to become the installation of rotor 4, subtracts significantly
Lack rotation and becomes space of the rotor 4 shared by diametric(al).
The motor electromagnetic shielding case 6 can effectively be isolated since motor and rotation become caused by too close motor to rotation
The electromagnetic interference of change.
8 one side of right axle bearing can support bushing inner ring, another aspect right axle bearing 8 to stretch out a boss,
It can be used for fixed rotation and become stator, reduce the weight of the shell of fixed motor stator, take full advantage of axial dimension, reduce
The width and rotary inertia of shafting.
In conclusion a kind of novel shafting of the utility model research and design, in order to compress the axis having shared by shafting as possible
To space, radial space being utilized to greatest extent, reduces the weight and rotary inertia of tilting component, rotation is become and is fixed on bearing block
On, electromagnetic shielding plate is devised between motor and rotation become, this design not only avoids influence of the motor-field to rotation varying magnetic field,
The weight and rotary inertia of tilting component are reduced simultaneously.
Above is only the preferred embodiment of the utility model, cannot limit the power of the utility model with this certainly
Sharp range, therefore equivalence changes made according to the patent scope of the utility model, still belong to the scope of protection of the utility model.
