Abstract
The invention discloses an undercarriage lifting device .The undercarriage lifting device comprises a first connecting sleeve used for containing an undercarriage .A shell is arranged on one side of the first connecting sleeve .A second connecting sleeve is arranged on the surface of the shell and penetrates through the middle of the first connecting sleeve .The first connecting sleeve can rotate around the second connecting sleeve .A bayonet is formed in the end of the first connecting sleeve, and a lead screw nut arranged on the surface of the shell can be clamped into the bayonet and can rotate on the surface of the shell .A lead screw penetrates through the middle of the lead screw nut, and the two ends of the lead screw are fixed by one-way thrust bearings respectively .A motor is arranged on the lower portion of one one-way thrust bearing at the lower end of the lead screw .The undercarriage lifting device has the advantages of being small in size, low in dead weight and simple in structure, and the flight performance of an unmanned aerial vehicle is greatly improved.
Description
Technical field
Present invention relates particularly to a kind of undercarriage lowering or hoisting gear.
Background technology
The undercarriage of professional unmanned plane is fixing non-retractable mostly.Existing the unmanned plane of operation of landing gear spring can be needed to provide power auxiliary to pack up, structure is complicated, and volume is big, and quality is big, and the most not only manufacturing cost is high, and owing to deadweight height affects flying quality.
Summary of the invention
For existing issue, the invention discloses a kind of undercarriage lowering or hoisting gear, it has, and volume is little, advantage from heavy and light and simple in construction, substantially increases the flying quality of unmanned plane.
Technical scheme is as follows:
A kind of undercarriage lowering or hoisting gear, including one for disposing the adapter sleeve one of undercarriage, the side of described adapter sleeve one is provided with a shell, and described case surface is provided with adapter sleeve two, described adapter sleeve two passes in the middle part of described adapter sleeve one, and described adapter sleeve one can rotate around described adapter sleeve two；The end of described adapter sleeve one is provided with a bayonet socket, clamping one can be located at a feed screw nut of described case surface in this bayonet socket, and described feed screw nut can rotate in described case surface；Being provided with a leading screw in the middle part of described feed screw nut, the two ends of this screw mandrel are fixed by a single thrust bearing respectively；One of them the single thrust bearing bottom being located at leading screw lower end is provided with a motor.
The invention discloses a kind of undercarriage lowering or hoisting gear, it has, and volume is little, advantage from heavy and light and simple in construction, substantially increases the flying quality of unmanned plane.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described.
Fig. 1 is the structure chart of undercarriage lowering or hoisting gear provided by the present invention.
In figure, numeral represents:
1, adapter sleeve 1, adapter sleeve 23, shell 4, bayonet socket 5, feed screw nut
6, leading screw 7, single thrust bearing 8, motor.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Shown in Fig. 1, a kind of undercarriage lowering or hoisting gear, including one for disposing the adapter sleeve 1 of undercarriage, the side of described adapter sleeve 1 is provided with a shell 3, described shell 3 surface is provided with adapter sleeve 22, described adapter sleeve 22 passes in the middle part of described adapter sleeve 1, and described adapter sleeve 1 can rotate around described adapter sleeve 22；The end of described adapter sleeve 1 is provided with a bayonet socket 4, clamping one can be located at the feed screw nut 5 on described shell 3 surface in this bayonet socket 4, and described feed screw nut 5 can rotate in described shell 3 surface；Being provided with a leading screw 6 in the middle part of described feed screw nut 5, the two ends of this screw mandrel 6 are fixed by a single thrust bearing 7 respectively；One of them single thrust bearing 7 bottom being located at leading screw 6 lower end is provided with a motor 8.During use, motor 8 operates, and drives leading screw 6 to rotate by bearing 7, and leading screw 6 drives feed screw nut 5 axial-rotation, owing to feed screw nut 5 is clamped in bayonet socket 4, and then drives adapter sleeve 1 to rotate to certain angle, reaches the purpose of operation of landing gear.
The invention discloses a kind of undercarriage lowering or hoisting gear, it has, and volume is little, advantage from heavy and light and simple in construction, substantially increases the flying quality of unmanned plane.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, and generic principles defined herein can realize without departing from the spirit or scope of the present invention in other embodiments.
