The specific embodiment
Below in conjunction with specific embodiment the utility model is described:
Present embodiment is the rotor rotation locking and placing device that is used on the rotor blade aircraft small scale model, and the diameter of its shaft 1 is 17mm, requires rotor rotation locking and placing device when rotating shaft 1 rotating speed drops to 50r/min, in 2s rotor is locked to assigned address.
With reference to accompanying drawing 1, the butt joint type rotor positioning of rotating locking and placing device that the utility model proposes comprises the rotor 4 that is fixed on the rotorshaft 1, with external driver device bonded assembly stop sleeve 2, and the socket cover 3 that is connected with outer fuselage.
Rotor 4 internal diameters are 17mm, and external diameter is 30mm, and axial height is 25mm, and rotor 4 is enclosed within the rotating shaft 1, and adopt lateral pin 5 that rotor 4 is fixing with rotating shaft 1, and rotor 4 cooperates an end to have " V " shape groove of symmetry with stop sleeve 2.Having the rotating shaft 1 of rotor 4 and rotor inertia that rotating shaft 1 outreaches rotor is 8.277kgm
2
With reference to accompanying drawing 1 and accompanying drawing 5, socket cover 3 is the template structure, there is through hole at the middle part, the through hole edge has the auricle mouth of symmetry, socket cover 3 is connected by the connecting bore and the outer fuselage at edge, make socket cover 3 relative outer fuselage remain fixing, stop sleeve 2 passes the through hole and the auricle mouth at socket cover 3 middle parts, and stop sleeve 2 and socket cover 3 free-running fits, auricle matches with the auricle mouth, make stop sleeve 21 to rotate around the shaft, and the length of auricle is greater than the axial motion distance of stop sleeve, make that auricle is subjected to the constraint of auricle mouth all the time when externally driving stop sleeve 2 along rotating shaft 1 axial motion.
To accompanying drawing 4, stop sleeve 2 can only be moved by the constraint of socket cover 3 vertically with reference to accompanying drawing 2, and socket cover 3 relative fuselages are fixed, so can be converted into the status requirement of stop sleeve 2 " V " shape groove to the fixed position locking requirement of rotor.Accompanying drawing 4 has provided the expansion drawing of rotor 4 and part stop sleeve 2, as can be seen from the figure " V " shape groove of rotor 4 is identical with " V " shape groove shape of stop sleeve 2, and the summit of " V " shape groove is a tip, azimuth between tip and adjacent bottom land differs 90 °, the purpose that adopts the tip summit is for fear of rotating speed when very low, and the situation of summit diebacks takes place for stop sleeve 2 and rotor 4.Because stop sleeve 2 all is a cylinder type with rotor 4, certain wall thickness is arranged, so " V " shape groove groove face that forms is a helical surface, and the helical surface of stop sleeve 2 and rotor 4 is isoparametric, thereby can guarantee that stop sleeve 2 all is that face contacts when contacting with rotor 4.Can advance downwards smoothly to push rotor 4 and to make rotor 4 rotate to assigned address in order to contact back stop sleeve 2 with rotor 4 at stop sleeve 2, stop sleeve can not be released when for rotating shaft rotation trend being arranged simultaneously, promptly form self-locking, requirement to " V " shape groove plane drift angle 2 θ after launching in the accompanying drawing 4 is: μ cos θ＞sin θ, wherein μ is the coefficient of static friction of rotor and stop sleeve.
When rotating shaft 1 rotating speed drops to 50r/min, external steering wheel is handled stop sleeve 2 and is moved downward, the helical surface of stop sleeve 2 " V " shape groove contacts with the helical surface of rotor 4 " V " shape groove, stop sleeve continues to advance downwards, push rotor 4 and rotate to assigned address, thereby realize the fixed point locking of rotating shaft 1 by rotor 4 drive rotating shafts 1.When needs recover rotating shaft 1 rotation, only need stop sleeve 2 be lifted by external steering wheel, make stop sleeve 1 lower end be higher than rotor 4 upper ends and get final product.
