Detailed description of the invention:
Embodiment one: present embodiments provide a kind of fan blade location structure, below with reference to accompanying drawing, this embodiment is described in further detail.
Being a kind of fan blade location structure as shown in Figure 1 to Figure 2, this fan blade location structure includes fan blade 2, is installed in the axle sleeve 3 of fan blade 2, and is arranged in the rotating shaft 1 of axle sleeve 3.Fan blade 2 is set in rotating shaft 1 by axle sleeve 3, and axle sleeve 3 and rotating shaft 1 coordinate and can carry out power transmission and give fan blade 2 being accurately positioned.In the present embodiment, fan blade 2 is metal fan blade, and in order to alleviate complete machine weight, it is preferred to aluminum fan blade.
As shown in Figure 3 to Figure 4, axle sleeve 3 includes a torque transfer part 31, is positioned at the first location division 32 of torque transfer part 31 side and is positioned at the second location division 33 of torque transfer part 31 opposite side, and torque transfer part the 31, first location division 32 and the second location division 33 are coaxially disposed.In the present embodiment, for Simplified flowsheet, the first location division 32, torque transfer part 31 and the second location division 33 are wholely set, and this preferred plastic material of axle sleeve 3, it is simple to produce and lighter in weight.Wherein, in order to tend to uniform and stable in moment of torsion transmittance process, the mating surface of torque transfer part 31 and fan blade 2 is regular polygon, and the present embodiment adopts regular hexagon, for the ease of installing and location, the mating surface of the 32, second location division, the first location division 33 and fan blade 2 is circle.Same in order to be easily installed, the external diameter of the first location division 32 is more than the external diameter of torque transfer part 31, and the external diameter of torque transfer part 31 is more than the external diameter of the second location division 33.
As shown in Figure 5 to Figure 6, fan blade 2 is provided with the hollow-out parts 21 coordinated with axle sleeve 3, this hollow-out parts 21 is provided with the first cylinder hollow out 212 that the regular hexagon hollow out 211 coordinated with torque transfer part 31 coordinates and the second cylinder hollow out 213 coordinated with the second location division 33 with the first location division 32, and the first cylinder hollow out 212, regular hexagon hollow out 211 and the second cylinder hollow out 213 are disposed adjacent successively.And corresponding to axle sleeve 3, the external diameter of the first cylinder hollow out 212 is more than the external diameter of regular hexagon cylinder hollow out 211, and regular hexagon cylinder hollow out 211 external diameter is more than the external diameter of the second cylinder hollow out 213.So, can when mounted axle sleeve 3 be embedded in the hollow-out parts 21 of fan blade 2.
It addition, as it is shown on figure 3, axle sleeve 3 is respectively arranged at two ends with protuberance: it is positioned at the head 321 of the first side, location division 32 and is positioned at the afterbody 331 of the second side, location division 33.The setting of head 321 and afterbody 331 makes the axial length axial length more than hollow-out parts 21 of axle sleeve 3, it is simple to the installation and removal of axle sleeve 3.Axle sleeve 3 also includes the through hole 34 coordinated with rotating shaft 1, and through hole 34 one end is provided with antislip ring 35.Antislip ring 35 has elasticity, and material can be the one in rubber, silica gel, is rubber antiskid circle in the present embodiment.The setting of antislip ring 35, it is simple to the installation of axle sleeve 3 and rotating shaft 1, and the tightness between axle sleeve 3 and rotating shaft 1 can be strengthened.Meanwhile, in order to not increase the heavy burden of axle sleeve 3 entirety, axle sleeve 3 is positioned at head end and is uniformly provided with hollow-out parts 36 radially.
Therefore in this fan blade location structure, the first location division 32 and the second location division 33 are positioned at torque transfer part 31 both sides, and respectively obtain the support of the first cylinder hollow out 212 and the second cylinder hollow out 213.Axle sleeve 3 utilizes the first location division 32 and the second location division 33 to make rotating shaft 1 form simply supported beam, thus fan blade 2 is supported and is accurately positioned.Torque transfer part 31 and regular hexagon hollow out 211 coordinate simultaneously, moment of torsion is transmitted by mating surface, even if torque transfer part 31 precision is not as high, or wear and tear to some extent after permanent use, excessively loosening without making between axle sleeve 3 and fan blade 2, also it is avoided that fan blade causes the vibration of complete machine to keep complete machine to operate steadily in rotation process.Therefore, the use of this fan blade location structure, it is possible to decrease axle sleeve 3 and the requirement on machining accuracy of hollow-out parts 21 and difficulty of processing in fan blade 2, technique is prone to control, and can increase the service life.
Embodiment two: present embodiments provide a kind of blower, it is a kind of garden tool set, is used for clearing up fallen leaves.This blower includes the fan blade location structure as described in embodiment one, and this fan blade location structure specifically refer to accompanying drawing 1 to 6.
By adopting the fan blade location structure as described in embodiment one in the present embodiment, the fan blade location structure required precision in this blower can be made low, difficulty of processing is low, technique is easily controlled, thus effectively reducing cost, and fan blade can be accurately positioned by this structure, can effectively reduce vibration amplitude when fan blade rotates during work, make blower operate steadily.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
