Embodiment
With reference to the accompanying drawings the present invention is described in detail.
Fig. 3 is the half-sectional view that has adopted the vacuum cleaner motor that possesses brush of an example of the present invention, and Fig. 4 is the decomposition side view of the brush part of Fig. 3, and Fig. 5 is the amplification profile along the V-V line of Fig. 4.As shown in the figure, the vacuum cleaner motor that possesses brush of the present invention comprises following structure and constitutes that promptly hood 11, and its inside has formed spatial accommodation; Rotating shaft 15, the inside that is installed in above-mentioned hood 11 also can rotate; Commutator 25 is connected a side of above-mentioned rotating shaft 15, can be with above-mentioned rotating shaft 15 rotations; The brush 31 that possesses carbon-point 32 and support 34, wherein an end in contact of above-mentioned carbon-point is on above-mentioned commutator 25, above-mentioned support then can provide support carbon-point in its inner mode that above-mentioned carbon-point 32 is packed into, thereby carbon-point 32 can be moved along the radial direction of rotating shaft 15; Nut 42 connects a side that is formed on above-mentioned hood 11; Bolt 35c is formed on the above-mentioned support 34, can be connected on the above-mentioned nut 42 with the screw ways of connecting.
In the inside of hood 11, rotating shaft 15 is equipped with in central authorities, and the two ends of rotating shaft 15 are subjected to the support of support plate (bearing), thereby can rotate.One side of hood 11 inside is equipped with impeller 13 along the axis direction of rotating shaft 15.For fluid being sucked, a side of hood 11 has formed the inlet hole 12 that connects, and along the axis direction of rotating shaft 15, a side of impeller 13 is equipped with stator 21.Rotor 23 is equipped with in the inside of stator 21, and rotor 23 can be the center rotation with rotating shaft 15.
One side of rotating shaft 15 is connecting the commutator 25 that can therewith rotate.In order to give rotor 23 energized, a pair of brush that keeps in touch with it respectively 31 is housed on the commutator 25.
Brush 31 is by constituting with lower member, that is: carbon-point 32, and its section is quadrangle, and along the radial direction of rotating shaft 15 and install, and an end contacts with commutator 25; Support 34 is connected on the above-mentioned hood 11, in its inner mode that above-mentioned carbon-point 32 is packed into carbon-point is provided support, thereby makes carbon-point 32 can carry out relative motion.Support 34 comprises with lower member: the carbon-point spatial accommodation 35a that can hold the quadrangle tubular of carbon-point 32; The connecting portion 35b in integrally formed with above-mentioned carbon-point spatial accommodation 35a, as can be connected hood 11 outside.Spring 37 is equipped with in the inside of carbon-point spatial accommodation 35a, and above-mentioned spring 137 can apply elastic force on an end of carbon-point 32, thereby makes carbon-point 32 keep Elastic Contact with commutator 25.
In addition, can move to the inside of hood 11 from the outside of hood 11, form nut 42 on the hood 11 in order to make carbon-point 32.Formed on the support 34 and can be connected to bolt 35c on the nut 42 with the screw ways of connecting.
Formed projection 36 on the connecting portion 35b of support 34, it is given prominence to towards hood 11, thereby can prevent that support 34 from rotating with respect to hood 11.Correspondingly, formed the projection spatial accommodation 44 that can hold above-mentioned projection 36 on the hood 11.After preventing that brush 31 from connecting upward, the vibration that bolt 35c and nut 42 are produced when rotating because of rotor 23 is become flexible, the section shape of above-mentioned projection 36 is skewed, and promptly with respect to the tightening direction of bolt 35c, its rear end is more outstanding to hood 11 directions than front end.
According to aforesaid structure, at first the end that exposes of carbon-point 32 is inserted the inside of nut 42, under bolt 35c and nut 42 state of contact,, thereby connect then the hand of spiral rotation of support 34 according to bolt 35c.When screw connects basic the end, projection 36 can touch the surface of hood 11, if continue rotation to support 34 according to same direction this moment, thereby projection 36 is entered in the projection spatial accommodation 44, so just can finish the connection of support 34 very easily.
In addition, because projection 36 is with respect to the tightening direction of above-mentioned bolt 35c, its rear end is more outstanding to above-mentioned hood 11 directions than its front end, thereby therefore under the vibrative situation of rotor 23 rotations, above-mentioned projection 36 can be touched with the side edge of projection spatial accommodation 44, thereby can prevent that bolt 35c is to unclamping the direction rotation.
