Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings clutch 1 according to an embodiment of the present invention for washing machine is described.
As shown in Figure 1-Figure 3, the clutch 1 according to an embodiment of the present invention for washing machine includes clutch shaft 100, clutch Set 200 and attachment device 300.
Clutch cover 200 is located on clutch shaft 100.Attachment device 300 the binding site combined with clutch cover 200 and with from Trap 200 is movably set on clutch shaft 100 between isolated disengaged position, and attachment device 300 includes along clutch shaft 100 Periphery wall multiple unidirectional rollers 310 of the circumferential array on clutch shaft 100, and attachment device 300 be equipped with only allow it is more Several special-shaped slots 340 that a unidirectional roller 310 is rolled along the circumferential one direction of clutch shaft 100.
Clutch 1 according to an embodiment of the present invention for washing machine, by the way that clutch cover 200 is located on clutch shaft 100, Attachment device 300 is moved between the binding site combined with clutch cover 200 and the disengaged position isolated with clutch cover 200 Ground is set on clutch shaft 100, can pass through the position change attachment device 300 and clutch cover 200 of change attachment device 300 Bonding state, to change the operating status of the washing machine.For example, when washing machine is washed, attachment device 300 It being separated with clutch cover 200, clutch shaft 100 individually rotates, when being dehydrated, attachment device 300 and 200 knot of clutch cover It closes, clutch cover 200 is driven to rotate together.To make the washing machine convert between dehydration and washing.
In addition, the unidirectional cooperation of roller 310 can be made different by the way that multiple unidirectional rollers 310 and several special-shaped slots 340 is arranged It, can be with since special-shaped slot 340 only allows multiple unidirectional rollers 310 to roll along the circumferential one direction of clutch shaft 100 in shape slot 340 It drives attachment device 300 to rotate together when making clutch shaft 100 along a direction rotation, and turns in another direction in clutch shaft 100 The rotation of attachment device 300 is not will drive when dynamic.To realize the function of unidirectionally driving, since the clutch 1 for washing machine is logical It crosses and transmission is realized using unidirectional roller 310 and attachment device 300, compared to using ratchet to embrace by the way of spring is driven in the related technology Washing machine, not only can be bad to avoid the transmission embracing spring sliding and generating, but also can prevent armful spring when load excessive from damaging It is bad, to improve the load capacity and reliability of the clutch 1 for washing machine.Compared in the related technology use brake ribbon and from The washing machine of clutch bearing-transmission, can not only rub the clutch for generating noise, but also can saving expensive to avoid brake ribbon Bearing, to reduce cost.
Therefore, the clutch 1 according to an embodiment of the present invention for washing machine is with highly reliable, load capacity is strong, makes an uproar The advantages that sound is small, at low cost.
Below with reference to the accompanying drawings the clutch 1 for washing machine of specific embodiment according to the present invention is described.
In some embodiments of the invention, as shown in Figure 1-Figure 3, according to an embodiment of the present invention to be used for washing machine Clutch 1 include clutch shaft 100, clutch cover 200 and attachment device 300.
Attachment device 300 can also include connection main body 320, and connection main body 320 can be in the knot combined with clutch cover 200 Coincidence is set movably to be set on clutch shaft 100 between the disengaged position isolated with clutch cover 200, connection main body 320 The roller slot 330 of the circumferentially extending of the inner peripheral surface along connection main body 320 can be equipped on inner peripheral surface, several special-shaped slots 340 can be with Along roller slot 330 internal perisporium circumferential array on the internal perisporium of roller slot 330, multiple unidirectional rollers 310 can be located at rolling In column slot 330.It is possible thereby to be convenient for the installation of multiple unidirectional rollers 310, and can be improved after multiple unidirectional rollers 310 install Stability.
Advantageously, as shown in Fig. 2, attachment device 300 can also include several spring leafs 350, each spring leaf 350 can be with It is clamped between two neighboring unidirectional roller 310.It is possible thereby to further increase the stability of unidirectional roller 310, list is prevented It is skidded off from connection main body 320 to roller 310, to guarantee the reliability of the clutch 1 for washing machine.
Specifically, unidirectional roller 310 is allowed to skid off special-shaped slot 340 as shown in Fig. 2, the inner wall of special-shaped slot 340 may include Skid off portion 341 and the unidirectional roller 310 of backstop skids off the stopper section 342 of special-shaped slot 340, skidding off portion 341 and stopper section 342 can be with Along the circumferential array of clutch shaft 100.Thus it not only can use the unidirectional roller 310 of 342 backstop of stopper section, prevent unidirectional roller 310 skid off special-shaped slot 340 from stopper section 342, and unidirectional roller 310 can be enable to skid off abnormity from the portion that skids off 341 is smooth Slot 340.
Optionally, the quantity of special-shaped slot 340 can be equal with the quantity of unidirectional roller 310.It is possible thereby to further increase The stability of unidirectional roller 310, and can guarantee special-shaped slot 340 to the limit effect of unidirectional roller 310, to further mention Reliability of the height for the clutch 1 of washing machine.
Fig. 3 shows the clutch 1 for washing machine of a specific example according to the present invention.As shown in figure 3, connection dress Set 300 towards can be equipped with the circumferential array along attachment device 300 on the surface of clutch cover 200 and be used for and clutch cover 200 The spline 360 of cooperation.It is possible thereby to be cooperated using spline 360 and clutch cover 200, clutch cover 200 is driven to be rotated, from And it can guarantee attachment device 300 and the reliability that clutch cover 200 is driven.
Advantageously, as shown in figure 3, the center of the central axis of 360 place circumference of spline and unidirectional 310 place circumference of roller Axis can be overlapped, and the diameter of 360 place circumference of spline can be greater than the diameter of unidirectional 310 place circumference of roller.Thus may be used So that attachment device 300 is easier to that clutch cover 200 is driven to be rotated.
Specifically, as shown in figure 3, spline 360 can be rectangular spline.It is possible thereby to guarantee spline 360 and clutch cover 200 The stability of cooperation, to guarantee the reliability of transmission.
