Abstract
The utility model relates to a clutch device for the inner shaft and the outer shaft of the speed reduction clutch of a fully-automatic washing machine. The utility model is the improvement for the planet speed reduction clutch of a fully-automatic washing machine. The outer part of the holding spring of the utility model is sheathed with a static ratchet wheel and a movable ratchet wheel. Outer arms which are bent at both ends of the holding spring are respectively clamped with the two ratchet wheels. The directions of the teeth of the two ratchet wheels are opposite. The frame of a ratchet pawl is provided with a lock pawl. The ratchet pawl and the lock pawl respectively act on the static ratchet wheel and the movable ratchet wheel. The clutching state of the clutch is completely controlled by the ratchet wheels. The work is reliable. The structure of an original clutch can be simplified.
Description
The utility model relates to clutch, particularly a kind of improvement of automatic washing machine planetary speed reducing clutch.
Automatic washing machine is realized two kinds of operations of washing and dehydration by a motor.During washing, about 180 rev/mins of impeller rotating speed, during dehydration, about 800 rev/mins of interior bucket rotating speed, the conversion of two kinds of operations is to be finished by a planetary speed reducing clutch, its " from " state, impeller is given in the rotation output slow-speed of revolution of interior axle, it " closes " state, and inside and outside axle is exported high rotating speed and given interior bucket with changeing.The structure of this clutch is that on the axle, interior axle input had an adapter sleeve that external diameter is identical with outer shaft in outer shaft was contained in.Clutch is embraced an end of spring and is held outer shaft tightly, and the other end is embraced on adapter sleeve, and the spring bending outer arm of embracing of this end inserts and be enclosed within the aperture of embracing the outer ratchet of spring, and ratchet unscrews direction and stirs ratchet to embracing a spring, can make to embrace a spring and unclamp adapter sleeve.When ratchet withdrawed from, an armful spring tightens up naturally embraced adapter sleeve.Embrace spring unclamp and hold tightly outer shaft in i.e. this clutch from close state.If in the washing operating mode, because impeller is positive and negative alternate rotation, brake be not stop fully under the situation of living, the outer shaft that links to each other with interior bucket can be given birth to transfer with the washings miscarriage, can screw embracing spring during the outer shaft counter-rotating, make clutch by " from " become " closing ", promptly non-artificial control ground changes the mode of operation of washing machine.For guaranteeing the reliable clutch of clutch, must install restriction outer shaft inversion set in the planetary speed reducing clutch of existing various automatic washing machines additional as unilateral bearing and so on, make it that structure is more complicated, cost is high.In addition, interior bucket can make the limit reversed device be subjected to frequent outer shaft counter-rotating and impact with the transfer trend of washing current, causes the spoilage of this device higher, and this device becomes automatic washing machine one of common faults parts the most.
The purpose of the utility model is to provide a kind of simple in structure, reliable inside and outside axle arrangement of clutch of clutch, to eliminate this failure factor of limit reversed device.
Outer shaft arrangement of clutch in described, clutch are embraced spring and are made two outer arm forms, embrace spring and are set with quiet, moving ratchet outward, and the teeth directional of quiet, moving ratchet is opposite.Two outer arms of embracing spring insert respectively in quiet, the moving ratchet end orifices.The quiet ratchet end of arrangement of clutch is sleeved on the outer shaft input, and moving ratchet end is sleeved on the interior axle adapter sleeve.Under free state, clutch is embraced spring and is tightened up naturally and embrace outer shaft and adapter sleeve, makes it to fuse.A lock pawl also is housed on the ratchet holder, and lock pawl and ratchet play the manipulation effect to quiet, moving ratchet respectively.
Washing machine is under static or washing state, and ratchet holder relies on the power of bullet (turning round) spring, and ratchet and lock pawl are successively acted on respectively on the dynamic and static ratchet.Moving ratchet is embraced direction that spring unscrewed with respect to quiet ratchet to clutch and is dialled and changeed an angle.Make clutch embrace spring and embrace the internal diameter of this end of adapter sleeve and become big and decontrol adapter sleeve, thereby realize separating of outer shaft and interior axle.At this moment, motor can only drive interior axle (impeller axle) and rotate the realization washing operation.In washing work, even the outer shaft generation transfer that links with washtub because ratchet and lock pawl block dynamic and static ratchet respectively, makes clutch embrace spring and remains the state of unscrewing.Thereby need not to limit the counter-rotational device of outer shaft, the released state of outer shaft in promptly can guaranteeing.
When washing machine dewatered work, haulage gear (as electromagnet) was when drawing back draining valve, and by brake and ratchet holder, driving lock pawl, ratchet successively break away from quiet, moving ratchet.Make clutch embrace spring and be in nature and tighten up state, outer shaft and adapter sleeve are embraced and fused the bonding state of outer shaft in realizing.At this moment, outer shaft rotates together in the driven by motor, realizes dehydrating operations.
Outer shaft arrangement of clutch in described, make clutch from, the state that closes fully by the control of dynamic and static ratchet, thereby its reliable operation, and can save the necessary limit reversed device of general automatic washing machine clutch, reduced the complexity and the production cost of whole planetary speed reducing clutch.Eliminated an important failure factor again.
The cutaway view of outer shaft arrangement of clutch in Fig. 1, described clutch;
Fig. 2, the action schematic diagram of described clutch.
The adapter sleeve 6 of interior axle 4 ends is identical with the external diameter of outer shaft 8, embrace in spring 3 is enclosed within, outer shaft 4,8 junction surface, and the outer arm 5 of embracing the spring two ends inserts respectively in the end orifices that is enclosed within its outer quiet ratchet 1 and moving ratchet 2, moving, quiet ratchet 1,2 teeth directional is opposite, a lock pawl 10 also is housed on the ratchet holder 11, when the electromagnet 12 drive draining valves 14 of washing machine are opened or are closed, pull bar 13 will drive angle θ of ratchet holder 11 swings, make ratchet 9 and lock pawl 10 with moving, quiet ratchet 2,1 tooth separates or contact, in the process of ratchet 9 lock pawls 10 incision ratchets, ratchet 9 successively contacts moving ratchet 2 and quiet ratchet 1 with lock pawl 10, behind the moving ratchet 2 of ratchet 9 contacts, can make ratchet 2 rotate an angle, thereby an armful spring 3 is unscrewed.Be noted that lock pawl 10 can be a rigidity, but its installation accuracy has relatively high expectations, lock pawl 10 also can be flexible, and the requirement of its installation accuracy is lower.
Claims (1)
1, the interior outer shaft arrangement of clutch of automatic washing machine, adapter sleeve 6, outer shaft 8 junction surfaces are with embraces spring 3, hold outer shaft 8 and adapter sleeve 6 under its nature tightly, one ratchet 9 is arranged on the ratchet installing rack 11, it is characterized in that: embracing spring 3 two ends has outer arm 5, embrace spring 3 outer quiet ratchet 1, the moving ratchets 2 of being set with, and two outer arms 5 of embracing spring 3 insert respectively in the aperture of quiet ratchet 1, moving ratchet 2 ends, a lock pawl 10 also is housed on the ratchet installing rack 11, and ratchet 9, lock pawl 10 act on moving ratchet 2 and quiet ratchet 1 respectively.
