Unless otherwise defined, technical term used herein or scientific terminology should be in field belonging to the present invention the ordinary meaning that the personage with general technical ability understands." first ", " second " that use in patent application specification of the present invention and claims and similar word do not represent any order, quantity or significance, and are only used to distinguish different constituent elements.Equally, the similar word such as " " or " " does not represent that quantity limits yet, but represents to there is at least one.
As shown in Figure 1, axle 1, output gear 2, clutch ring 3, input gear 4 and upper cover 5 is comprised according to the clutch mechanism of the embodiment of the present invention.
Center hole and the axle 1 of output gear 2 are rotationally connected.Clutch ring 3 is positioned at the top of output gear 2, and is fixedly connected with axle 1.In the embodiment shown in fig. 1, the clutch ring 3 draw-in groove phase clamping by the through hole in the middle part of it and axle 1 are arranged, thus realization is when axle 1 rotates, clutch ring 3 is fixedly connected with axle 1.
As depicted in figs. 1 and 2, the periphery along clutch ring 3 outwards expands at least one downward-sloping clutch pawl 31.Circumferentially abducent direction can be counter clockwise direction as depicted in figs. 1 and 2, also can be clockwise direction.The number of clutch pawl 31 can be one or more, and in the illustrated embodiment, the number of clutch pawl 31 is three.
As shown in Figure 1, the upper-end surface of output gear 2 is provided with the convex tendon 21 coordinated with clutch pawl 31.Input gear 4 is fixed on axle 1, is positioned at the below of output gear 2.
In the embodiment in figure 1, clutch pawl 31 along the periphery of clutch ring 3 with counterclockwise to external expansion.When input gear 4 is driven and rotates counterclockwise, input gear 4 is with moving axis 1 to rotate, and clutch ring 3 rotates counterclockwise with axle 1, and the downward-sloping one end of clutch pawl 31 props up convex tendon 21, thus promotes output gear 2 and rotate counterclockwise.Now, input gear 4 is by clutch ring 3 driver output gear 2 rotating in same direction, and the rotating speed of clutch ring 3 is not less than the rotating speed of output gear 2.And when the rotating speed of output gear 2 is greater than rotating speed (clutch ring 3 is identical with input gear 4 rotating speed and output gear 2 is identical with output gear 4 sense of rotation) of clutch ring 3, clutch pawl 31 skims over from convex tendon 21 because elasticity is skidded, do not transmit rotatory force to output gear 2, thus realize the clutch of output gear 2 and output gear 4.Clutch pawl 31 in Fig. 1 has certain flexible strip cantilever, and it also can adopt other shape in other embodiments.
Output gear 2 in Fig. 1 is relative with the driving relationship of input gear 4.If output gear 2 is driving gear, and turns clockwise, the convex tendon 21 of output gear 2 promotes clutch ring 3 clockwise movement by clutch pawl 31, thus drives input gear 4 to rotate clockwise.Now, output gear 2 drives input gear 4 rotating in same direction by clutch ring 3, and the rotating speed of input gear 4 is not less than the rotating speed of output gear 2.And when the rotating speed of input gear 4 is greater than the rotating speed of input gear 2, clutch pawl 31 skims over from convex tendon 21 because elasticity is skidded, do not transmit rotatory force to input gear 4, thus realize the clutch of output gear 2 and output gear 4.Under this kinematic relation and driving direction, can be considered as input gear by gear 2, gear 4 is output gear.
Clutch pawl 31 skims over from convex tendon 21 because elasticity is skidded, and does not transmit rotatory force to output gear 2, thus plays the effect of protection motor.
In one embodiment, clutch mechanism also comprises upper cover 5.Upper cover 5 covers clutch ring 3, and is tightly connected with the upper-end surface of output gear 2.As shown in Figure 2, the peripheral edge of upper cover 5 can be provided with multiple clamping unit 51, by this clamping unit 51, the upper-end surface of upper cover 5 with output gear 2 is tightly connected, thus form a confined space between upper cover 5 and the upper-end surface of output gear 2.Damp liquid can be provided with in this confined space.When output gear 2 rotates at faster speed and departs from the driving of input gear 4, the damp liquid in upper cover 5, by the damping function to convex tendon 21, can rotate the acceleration of output gear 2 and play buffer function; When input gear 4 rotates at faster speed and departs from the driving of output gear 2, the damp liquid in upper cover 5, by the damping function to clutch pawl 31, can rotate the acceleration of input gear 4 and play buffer function.This damp liquid can also reduce the generation of noise.
Clutch mechanism according to the embodiment of the present invention can be arranged in the train of reduction gears of valve controller for opening and closing.Fig. 3 shows a kind of overall appearance of valve controller for opening and closing, and it applies the clutch mechanism according to the embodiment of the present invention.This valve open and close controlling mechanism, comprising: housing 6, motor 10, train of reduction gears 20 and cam 30.
As can be seen from Figure 3 the profile of the housing 6 of described valve controller for opening and closing.Face shown in Fig. 3 is the open face of housing, is provided with upper half part (upper body, i.e. cap) of described housing 6 thereon.As shown in the figure, the output shaft 204 of train of reduction gears 20 is through upper body, and cam 30 is arranged on the part that this output shaft 204 stretches out housing 6.When valve open and close controlling mechanism works, output shaft 204 driving cam 30 rotates.
Cam 3 pulls with control valve 9 by a connecting rod 901, as illustrated in figs. 5 a-5 c.In fig 5 a, cam 3 is in initial position (such as drawing corner=0 °), and valve 9 cuts out, and under the driving of motor, cam 3 will rotate counterclockwise, thus drivening rod 901 moves.As shown in Figure 5 b, along with the rotation of cam 3, connecting rod 901 makes valve 9 open, and the spring 902 of valve 9 is by compression also energy accumulation.As shown in Figure 5 c, after cam 3 turns over dead point (such as drawing corner=180 °), spring 902 Quick-return in valve 9, band moving cam 3 returning quickly, now the rotating speed of cam 3 is greater than the driving rotating speed of live axle 204.
In other embodiments in accordance with the invention, cam 3 also can by carrying out open valve 9 along clockwise movement.In addition, alternatively, when valve 9 is opened spring 902 stretch energy accumulation and when cam returning quickly spring 902 shrink release energy.
Alternatively, this output shaft 204 also can be the output shaft of other gear train or the mechanism driven by train of reduction gears 20.Therefore, can think that output shaft 204 is output shafts of valve controller for opening and closing.
As shown in Figure 4, train of reduction gears 20 comprises actuation gear 201, second level reduction gear 202 and third level reduction gear 203.Driven the actuation gear 201 of train of reduction gears 20 by motor 10, actuation gear 201 engages with second level reduction gear 202, thus drives second level reduction gear 202.Second level reduction gear 202 engages with third level reduction gear 203, and specifically, as shown in Figures 2 and 3, the upper strata gear of second level reduction gear 202 engages with third level reduction gear 203, thus drives third level reduction gear 203.
Third level reduction gear 203 is arranged at according to the clutch mechanism of the embodiment of the present invention.Wherein, the upper strata gear that third level reduction gear 203 diameter is larger corresponds to aforementioned output gear 2, and lower floor's gear that diameter is less corresponds to signature input gear 4.The upper strata gears meshing of this upper strata gear (output gear 2) and second level reduction gear 202, and be driven by it.Owing to being train of reduction gears, therefore, output gear 2 serves the driving effect of driving gear, and input gear 4 is output gear 2 and drives, and the driving torsion of motor is delivered to output shaft 204 directly or indirectly.
When cam 3 returning quickly, the rotating speed of cam 3 is greater than the driving rotating speed of live axle 204, and by transmitting, the rotating speed of output gear 4 is greater than the rotating speed of output gear 2 (but identical when sense of rotation and output gear 2 drive input gear 4).Owing to can realize output gear 4 and the clutch of output gear 2 according to the clutch mechanism of the embodiment of the present invention, therefore, in the process of cam 3 returning quickly, between output gear 4 and input gear 2, be achieved the disengaging that torsion transmits.So input gear 2 can not limit the quick rotation of output gear 4, thus the valve 9 of Quick-return can be protected; Input gear 2 also can not rotate along with output gear 4 at faster speed, thus can protect motor.According to valve open and close controlling mechanism of the present invention, can be applied to and carry out by motor the control valve unit that controls, preferably, be applicable to drain valve assembly, more preferably, be applicable to the drain valve assembly of washing machine.
The above is only exemplary embodiment of the present invention, but not for limiting the scope of the invention, protection scope of the present invention is determined by appended claim.
