Abstract
The utility model belongs to processing method, and in particular to a kind of sleeve configuration steering wheel structure.A kind of sleeve configuration steering wheel structure, wherein, including servomotor, first order reducing gear is connected on the output shaft of servomotor, then by two level conversions, the swing for being converted to final output axle that servomotor is exported.Effect of the present utility model is：By the improvement to traditional steering wheel kind of drive, length direction bulk effectively is utilized, in limited width and short transverse bulk, realizes big speed ratio, meet overall mechanical index and the appearance and size requirement to steering wheel.
Description
Technical field
The invention belongs to processing method, and in particular to a kind of sleeve configuration steering wheel structure.
Background technology
Certain type of missile caliber is small, using the teaching of the invention it is possible to provide the installing space size to steering wheel is long and narrow.By optimizing steering wheel
The kind of drive and structure design, meet overall profile and bearing requirements to steering wheel.
Steering wheel often includes the shapes such as straight-tooth/angular gear transmission, Harmonic Gears, ball-screw-transmission with transmission mechanism
Formula.Wherein ball-screw transmission mechanism has the advantages that load capacity is big, transmission efficiency, rigidity are high, drive mechanism is compact.Root
According to general requirement mechanical index, preferably using ball-screw transmission mechanism.
Ball-screw generally has three kinds of structure types in steering wheel transmission：1. ball-screw+connecting rod+rocking arm；2. ball wire
Thick stick+shift fork；3. ball-screw+rocking arm.Three of the above structural shape can realize ball-screw transform linear motion for output
Axle rotates, if but steering wheel want to possess compared with big speed ratio, unless be improved optimization to these three structural shapes, otherwise physical dimension
On can not meet general requirement index.
The content of the invention
A kind of the defects of present invention is directed to prior art, there is provided sleeve configuration steering wheel structure.
The content of the invention：A kind of sleeve configuration steering wheel structure, wherein, including servomotor, connect on the output shaft of servomotor
First order reducing gear is connect, then by two level conversions, the swing for being converted to final output axle that servomotor is exported.
A kind of sleeve configuration steering wheel structure as described above, wherein, described first order reducing gear is planetary gear set.
A kind of sleeve configuration steering wheel structure as described above, wherein, two described level conversions refer to, planetary gear set it is defeated
Shaft is fixed together by key connection and ball-screw, and by the linear motion for being converted into leading screw of planetary assemblies, rolling
Ballscrew is hinged long connecting rod by trundle, and long connecting rod is hinged output shaft by trundle.
The present invention effect be：By the improvement to traditional steering wheel kind of drive, length direction bulk effectively is utilized,
In limited width and short transverse bulk, big speed ratio is realized, meets overall mechanical index and to rudder
The appearance and size requirement of machine.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of sleeve configuration steering wheel structure.
In figure：1. servomotor, 2. planetary gear sets, 3. ball-screws, 4. connecting rods, 5. output shafts, 6. trundles.
Embodiment
As shown in Figure 1, a kind of sleeve configuration steering wheel structure, including servomotor 1, it is solid on the output shaft of servomotor 1
Surely planetary gear set 2 is connected, the output shaft of planetary gear set 2 is fixed together by key connection and ball-screw 3, and will
The linear motion for being converted into leading screw of planetary assemblies, ball-screw 3 are hinged long connecting rod 4 by trundle 6, and long connecting rod 4 is logical
Cross trundle 6 and be hinged output shaft 5.
Functionally：(1) planetary gear set 2 is fixed on the output shaft of servomotor 1 by pin, is formed one-level and is subtracted
Speed；(2) ball-screw 3 is fixed together by key connection and planetary wheeling assembly 2, and the rotation of planetary assemblies is converted into leading screw
Linear motion；(3) ball-screw 3 and long connecting rod 4 are hinged with trundle 6；(4) long connecting rod 4 and the trundle 6 of output shaft 5
It is be hinged；(5) by the be hinged of two trundles 6, the linear motion of ball-screw 3 is eventually converted into the swing of output shaft.
