Abstract
The utility model discloses a rapid propeller assembling/disassembling structure, which comprises a propeller sleeved on an output shaft of a motor rotor, wherein a propeller clamp is arranged between the propeller and the motor rotor, sleeved on the output shaft and fixedly connected with the motor rotor; a groove is formed at the upper end of the propeller clamp; the propeller is clamped into the groove and follows the motor rotor to rotate together with the propeller clamp; and the propeller and the propeller clamp are bonded by using a rubber band, thereby preventing the propeller from sliding axially. Therefore, the rapid propeller assembling/disassembling structure which is simple in structure and convenient to assemble/disassemble is provided.
Description
Technical field
The utility model relates to a kind of aircraft, particularly a kind of carry-on screw propeller fast assembling disassembling structure.
Background technology
The screw propeller of existing aircraft generally adopts bearing pin directly to be fixed on the motor output shaft, can't dismounting, give aircraft transportation, deposit and bring inconvenience.
The utility model content
The utility model purpose is in order to overcome the deficiencies in the prior art, to provide a kind of simple in structure, a kind of screw propeller fast assembling disassembling structure of easy disassembly.
The purpose of this utility model is achieved through the following technical solutions:
A kind of screw propeller fast assembling disassembling structure, comprise screw propeller, screw propeller is sleeved on the output shaft of a rotor, be provided with oar folder between screw propeller and the rotor, the oar chuck is contained on the output shaft and with rotor and is fixedly linked, oar folder upper end has groove, and the screw propeller holding is rotated with rotor together with the oar folder in groove, also bundlees to prevent that by bungee prop shaft is to slip between screw propeller and the oar folder.
Embodiment: the oar folder is the aluminium matter connecting strap of global formation, have groove in upper end, aluminium matter connecting strap middle part, bottom portion of groove is provided with the axis hole that the power supply machine output shaft passes and the connecting bore that is positioned at the axis hole both sides, bolt is locked oar folder and rotor through connecting bore, aluminium matter connecting strap both sides are provided with engaging lug, and bungee is walked around two engaging lugs and pressed simultaneously screw propeller and is connected with the binding of screw propeller to realize the oar folder.
Further improve: connecting bore is the frustum type hole that upper end open is large and lower ending opening is little, bolt is the cross flat head bolt, when locking oar folder and rotor, the stub end that the stub end of bolt is positioned at large opening one end of connecting bore and bolt does not exceed the connecting bore outer face.
The utility model has following advantage and effect with respect to prior art: be provided with oar folder between screw propeller and the rotor, the oar chuck is contained on the output shaft and with rotor and is fixedly linked, the screw propeller holding is rotated with rotor together with the oar folder in groove, also bundle to prevent that by bungee prop shaft is to slip between screw propeller and the oar folder, when the dismounting screw propeller, only need to take off bungee like this, can take out screw propeller, convenient disassembly along the output shaft horizontal drawing again; Also only need to make in the groove of screw propeller holding on the oar folder along output shaft horizontal sliding and rotating screw propeller angle during installation, then get final product with the bungee binding, easy for installation; Because oar folder light weight and little, be contained in the transportation that do not affect aircraft on the aircraft, deposit, screw propeller is elongated, then greatly facilitate behind the dismounting screw propeller aircraft transportation, deposit.
