Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As Figure 1-4, gear assembly, including pinion stand 2 and the gear 4 that is spindle rotationally arranged on pinion stand 2.The toroidal inductive part 6 of induction gear 4 rotational angle it is additionally provided with between gear 4 and pinion stand 2, multiple shackle member 8 circumferentially it are provided with inside pinion stand 2, toroidal inductive part 6 is fixed on pinion stand 2 by the snap-fit engagement of outer rim Yu shackle member 8, and toroidal inductive part 6 is provided with some spacing holes 62 vertically, pinion stand 2 is provided with limited post 228 and is located in corresponding spacing hole 62.
Pinion stand 2 includes the base 22 of tabular and is vertically set on the sidewall 24 at base 22 edge.Wherein the middle part of base 22 is provided with the axis hole 222 installing gear 4, inside base 22, axis hole 222 periphery be also coaxially provided with the ring-type convex tendon 224 that inner edge shape and toroidal inductive part 6 outer rim matching form close.Concrete, ring-type induction pieces is circular, and ring-type convex tendon 224 should be circular mutually.Setting three shackle member 8 on pinion stand 2 altogether, circumference is distributed on the circumference of ring-type convex tendon 224, the most ring-type convex tendon 224 be circumferentially with breach at three, shackle member 8 be arranged on correspondence indentation, there.More specifically, the base 22 of corresponding indentation, there is provided with and shackle member 8 one_to_one corresponding the through hole 226 of accommodating corresponding shackle member 8.Shackle member 8 is J-shaped elastic component, and one end is fixed on outside pinion stand 2 base 22, and the other end is by stretching out through hole 226 in pinion stand 2 lateral and protruding from base 22 medial surface, intermediate formation corner part 82.And the free end of shackle member 8 bends to hook-shaped to axis hole 222 centrage C direction, the end 84 at hook-shaped position is in the arc-shaped protrusions shape towards axis hole 222 centrage C.
On pinion stand 2 base 22, circumference is evenly equipped with two limited posts 228, and limited post 228 is arranged between axis hole 222 and ring-type convex tendon 224.So, when toroidal inductive part 6 is contained in ring-type convex tendon 224, limited post 228 and spacing hole 62 coordinate, and toroidal inductive part 6 can well be avoided to circumferentially rotate.
Toroidal inductive part 6 is provided with two axially extended binding posts of difference 64, and pinion stand 2 is provided with and accommodates the accommodating hole 229 that corresponding binding post 64 passes.
Gear 4 is arranged on pinion stand 2, the outside of toroidal inductive part 6, including a mandrel 42.The mandrel 42 of gear 4 is located in axis hole 222, is spindle rotationally arranged in pinion stand 2 base 22, can drive the motion coordinating corresponding component with gear 4.Such as arranging gear 4 is eccentric gear, also has an eccentric shaft 44 in addition to mandrel 42.Its eccentric shaft 44 can be connected with the valve rod of valve, and when arranging driven by motor eccentric gear and rotating, eccentric shaft 44 can move back and forth by band ovable valve stem in certain guider.
During installation, by toroidal inductive part 6 with binding post 64 one facing to inside pinion stand 2, adjust circumference angle, binding post 64 is made to be located in the accommodating hole 229 of correspondence, spacing hole 62 coordinates with the limited post 228 of base 22, then snaps in the ring-type convex tendon 224 of base 22, and the end 84 at three hook-shaped positions of shackle member 8 all props up toroidal inductive part 6 to centrage C direction, thus fix toroidal inductive part 6, finally the mandrel 42 of gear 4 is arranged on the axis hole 222 of pinion stand 2.
It should be noted that, toroidal inductive part 6 can be the industry general can the sensing device of induction gear 4 rotational angle, concrete, the present embodiment uses annular circuit board as induction pieces, Magnet installing hole 46 is set on gear 4, and Magnet is installed, the Hall element 66 of circumferentially distributed some induced magnets on annular circuit board.During use, gear 4 rotates relative to toroidal inductive part 6, and Hall element 66 i.e. receives the position of gear 4, and meanwhile by binding post 64 external controller, Hall element 66 can be by gear 4 position signalling transfer control.Controller can be connected with gear 4 driving means, controls the rotational angle of gear 4 as required.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to determine technical scope according to right.
