Description
Technical field
Head field is the utility model is related to, feature is related to miniature head field.
Background technology
Now remote control multi-rotor aerocraft will carry greatly be provided with shooting equipment head taken photo by plane, with science skill
The development and progress of art, the manufacturing technology for shooting equipment also constantly improve, and the volume for shooting equipment does less and less, shooting
Precision also become better and better.The heads for installing these shooting equipment also want small volume, and the support arm running accuracy in head will also carry
Height, it so can just shoot precision height, clearly image.
The content of the invention
The utility model discloses a kind of high-precision rotary simple in construction, easy to adjust, cost is cheap, running accuracy is high
Miniature head.
In order to solve the above technical problems, technical scheme is used by the utility model：The miniature head of high-precision rotary
At least provided with a support arm, the support arm is rotated by outer rotor motor driven, and the power transmission shaft in the outer rotary electric machine is set
There are two zanjon bearings, the bearing block in the external rotor electric machine connects the outer ring of two zanjon bearings, described two zanjon axles
Hold centre and be provided with spring/axle sleeve, the outside of described two zanjon bearings is provided with packing ring, wavy spring is provided with the outside of the packing ring.
Further, at least provided with three ripples in the wavy spring.
The beneficial effect of the miniature head of high-precision rotary of the present utility model is：Due to using bullet among zanjon bearing
Spring/axle sleeve and outside use wavy spring, and the regulation of running accuracy can be thus carried out to zanjon bearing, and adjust also very square
Just.Zanjon bearing eliminates the clearance of zanjon bearing by such adjusting method, make zanjon bearing inner ring and outer ring continuously
Unoccupied place rotates.So that the running accuracy for the head support arm that external rotor electric machine is driven is improved, the bat that miniature head carries
Take the photograph that the precision of images captured by equipment is high, definition is more preferable, while head miniaturization also mitigates remote control multi-rotor aerocraft
Weight, also improve the flying quality of remote control multi-rotor aerocraft.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the structural representation of the external rotor electric machine in the utility model.
Fig. 3 is the assembling schematic diagram of zanjon bearing, spring, wavy spring.
Embodiment
As shown in Figure 1 to Figure 3, the embodiment of the miniature head of high-precision rotary of the present utility model, such as Fig. 1 to Fig. 3 institutes
Showing, the miniature head 1 of this high-precision rotary is provided with support arm 2, support arm 2-1, and the both sides position of support arm 2 is provided with external rotor electric machine 3,
The support arm 2-1 sides also are provided with external rotor electric machine.Installation shooting equipment 50 in the support arm 2-1.So external rotor electric machine drives
Dynamic support arm 2, support arm 2-1 do the rotation that Y, Z-direction and shooting equipment do X-axis.
As shown in Figure 2 to Figure 3, the power transmission shaft 6 set by the middle part of rotor 4 in the external rotor electric machine 3 is provided with two
Zanjon bearing 8, the bearing block 7 set by the middle part of stator 5 in the external rotor electric machine 3 connect the outer of two zanjon bearings 8
8-1 is enclosed, spring 9 is provided among the outer ring 8-1 of described two zanjon bearings 8（Axle sleeve can also be used, the present embodiment only uses bullet
Spring.）.The side of the packing ring 10 is abutted on the outside of the inner ring 8-2 of each zanjon bearing 8, the opposite side of the packing ring 10 supports
The side of welding wave spring 11, the opposite side of one of them of the wavy spring 11 abut rotor 4, the wavy spring 11 its
In another opposite side abut gland 12, the gland attachment screw 13.When screw is connected set by power transmission shaft by gland
Inner hole thread after, turn screw and push down the pressure that wavy spring is adjusted in gland, pressure caused by wavy spring passes through pad
Circle pushes up the inner ring to zanjon bearing, and the packing ring that at this moment spring among outer ring and inner ring abut acts in the pressure of wavy spring
Under, the Internal and external cycle of zanjon bearing is subjected to displacement the clearance for reaching and eliminating zanjon bearing, the rotor of external rotor electric machine is carried out continuously
Unoccupied place rotates, so as to improve the rotation precision of the X, Y, Z axis of head of the present utility model.
The pars intermedia of stator 5 in the embodiment of the miniature head of high-precision rotary of the present utility model in external rotor electric machine 3
The diameter of bearing block 7 set by position can only use zanjon bearing typically at 20 to 10 millimeters, in so small diameter range, but zanjon
Bearing will produce clearance, eliminated using the bidirectional elastic pressure of two springs for clearance the utility model, so adjusted
The operation of spring pressure is saved than being also more convenient using the regulation of axle sleeve.Adjusted by the clearance of zanjon bearing, so as to improve this reality
With the miniature head running accuracy of new high-precision rotary, shooting equipment is set to be shot in the high-precision rotation of miniature head
Go out precision of images height and clearly picture.
