Abstract
The invention relates to a hub, which is used for fixing vanes and comprises a left half hub and a right half hub symmetrical to each other. The right half hub is located between a motor and the left half hub, the motor is used for driving the vanes to rotate, a plurality of positioning holes which are circularly arrayed around the axis of the hub are arranged on the side wall of the hub, an axle hole sleeved with a motor shaft is arranged at the center of the hub, axes of the positioning holes extend along the radius direction of the hub and located on a splicing surface between the left half hub and the right half hub, and a first reinforcing rib is respectively arranged between the outside bottom of each positioning hole and the axle hole. By the aid of the first reinforcing ribs arranged between the outside bottoms of the positioning holes and the axle hole, the strength of the hub is guaranteed, materials for making the hub are saved and cost is reduced.
Description
?
Technical field
the present invention relates to a kind of wheel hub, relate in particular to the good wheel hub of a kind of intensity high stability.
?
Background technique
The intensity of
wheel hub has very big influence to the stability of blade movement, therefore when producing wheel hub, the intensity of wheel hub is wanted higher requirement.Do not have stiffening rib between the positioning hole outside of existing wheel hub and the axis hole, and thinner in order to save the material hub thickness, so wheel hub intensity is lower, blade movement is also unstable, influences the air quantity that blade produces.
?
Summary of the invention
the object of the invention provides the good wheel hub of a kind of intensity high stability.
in order to achieve the above object; The technological scheme that the present invention adopted is: a kind of wheel hub; It is used for fixing blade; It comprises a symmetrical left side half wheel hub and right half wheel hub; The described right side half wheel hub is between the motor and left half wheel hub that drive with blade rotation; Offer a plurality of positioning holes and its center that distribute for the center line circular array with the hub axis on the sidewall of described wheel hub and offer the axis hole that is set on the motor shaft, the axis of described positioning hole is positioned on the splicing surface of left half wheel hub and right half wheel hub along extension of hub radius direction and axis, is provided with first stiffening rib between the bottom in each described positioning hole outside and the axis hole.
Two adjacent positioning hole outsides of
all are connected with second stiffening rib.
Offer the locating slot that is used for fixing blade on
each positioning hole madial wall, position relative with locating slot on the outer side wall of each positioning hole is provided with the reinforcement projection.
are owing to adopt technique scheme; The present invention has the following advantages: be provided with first stiffening rib between bottom outside positioning hole and the axis hole; Guarantee the intensity of wheel hub, saved simultaneously and made the required material of wheel hub, reduced cost.

Embodiment
describe the preferred specific embodiment of the present invention below in conjunction with accompanying drawing.
are as shown in Figure 1, and this wheel hub is used for fixing blade, and it comprises a symmetrical left side half wheel hub 1 and right half wheel hub 2, and the described right side half wheel hub 2 is between the motor and left half wheel hub 1 that drive with blade rotation.
are as shown in Figure 2; Offer eight positioning holes 3 and its center that distribute for the center line circular array with the hub axis on the sidewall of described wheel hub and offer the axis hole 4 that is set on the motor shaft, the axis of described positioning hole 3 is positioned on the splicing surface of left half wheel hub 1 and right half wheel hub 2 along extension of hub radius direction and axis.Be provided with first stiffening rib 5 between the bottom in each described positioning hole 3 outside and the axis hole 4; And two adjacent positioning hole 3 outsides all are connected with second stiffening rib 6; For further guaranteeing the intensity of each positioning hole 3, offer the locating slot that is used for fixing blade on each positioning hole 3 madial wall, the position relative with locating slot is provided with and strengthens projection 7 on the outer side wall of each positioning hole 3.
above-mentioned combination is illustrated embodiment preferred for this invention; But the foregoing description can not be interpreted as the restriction to protection domain of the present invention, and all equivalences that spirit is done according to the present invention change or modification all should be encompassed within protection scope of the present invention.
