Description

Technical Field

[0001] A clutch engagement / disengagement gear structure is disclosed. This invention belongs to the field of washing machine clutch technology, specifically relating to the field of clutch engagement / disengagement gear structure technology. Background Technology

[0002] The washing machine clutch is the core transmission component of a pulsator-type fully automatic washing machine. It undertakes key functions such as power switching between washing and spin-drying modes and braking. The design of its clutch separation gear structure directly affects the washing machine's operational stability, transmission efficiency, and service life.

[0003] Existing washing machine clutches mostly employ a traditional transmission method using a shift fork and sliding sleeve, which has the following drawbacks: First, the clutch engagement and disengagement limiting and guiding effect is poor, and the transmission components are prone to misalignment and jamming during axial movement and circumferential rotation, resulting in unsmooth power switching and abnormal noise during washing and spin-drying mode switching; Second, the fit between the engagement and disengagement transmission components and the brake and clutch retaining sleeve is poor, resulting in high transmission torque loss and accelerated wear of components due to uneven local stress; Third, the transmission linkage of the adjustment structure is poor, and the operating force transmission efficiency of the lever is low, making clutch engagement and disengagement difficult, and the adjustment structure is prone to loosening and failure after long-term use; Fourth, the assembly and fixing methods of each component are cumbersome, making disassembly and maintenance difficult and increasing later maintenance costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a clutch engagement / disengagement gear structure, thereby solving the problems of poor limit guidance, transmission jamming, large torque transmission loss, laborious adjustment operation and inconvenient disassembly and maintenance of the existing clutch engagement / disengagement structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A clutch engagement / disengagement gear structure includes a washing machine clutch body.

A base plate is mounted on the top of the upper housing cover, and a side limiting ring is connected to the top of the base plate. A top pressure plate is engaged with the top of the side limiting ring. The output shaft of the washing machine clutch body passes through and extends above the top pressure plate. The top of the brake part of the washing machine clutch body is located inside the side limiting ring, and an engagement / disengagement transmission component is sleeved on the outside of the brake part. A lever plate is sleeved on the outer side of the bottom end of the disengagement transmission component. Arc-shaped grooves are evenly distributed on the edge of the lever plate. An arc-shaped boss is installed on the inner wall of the side limiting ring at the position of the arc-shaped groove. A protrusion is installed on the side of the lever plate. An adjustment structure connected to the protrusion and capable of moving it is installed on the side of the upper shell cover. A spring is installed between the top end of the disengagement transmission component and the bottom end of the top pressure plate. A clutch fixing sleeve is sleeved on the outside of the output shaft above the top of the brake part. A pulley is installed on the outside of the output shaft above the clutch fixing sleeve through a clamping nut.

[0007] As a preferred embodiment of the present invention, the base plate has a connecting boss one distributed on its side, and the side limiting ring has a connecting boss two distributed on its side. Both the connecting boss one and the connecting boss two have mounting holes inside, and the connecting boss one and the connecting boss two are fixed to the outside of the upper shell cover by bolts.

[0008] As a preferred embodiment of the present invention, the outer side of the brake part is provided with conical protrusions, and the interior of the disengagement transmission component is provided with grooves corresponding to the conical protrusions; a limiting ring is provided on the side of the disengagement transmission component above the shift plate to limit its movement; the bottom end of the disengagement transmission component is evenly distributed with lower protrusions, the interior of the base plate is provided with a slot corresponding to the lower protrusions, the top end of the disengagement transmission component is evenly distributed with upper protrusions, and the clutch fixing sleeve is provided with a slot corresponding to the upper protrusions. The lower protrusions and upper protrusions are equidistantly distributed along the circumference of the disengagement transmission component and their cross-sections are all arc-shaped. The number of them can be selected as 3-6 sets according to the clutch specifications, and the arc curvature is adapted to the rotation and axial movement requirements of the transmission component.

[0009] As a preferred embodiment of the present invention, the protrusion has a connecting hole inside, and the adjustment structure includes a U-shaped seat disposed on the side of the upper shell cover. The U-shaped seat has a fixing hole inside, and a connecting shaft is installed inside the fixing hole. A conduction plate is fixed outside the connecting shaft above the U-shaped seat. A protruding post inserted into the connecting hole is disposed at the top of the conduction plate. A connecting key is disposed on the bottom side of the conduction plate. The connecting key is disposed on the outside of the U-shaped seat. A pull rod is fixed outside the connecting shaft inside the U-shaped seat. A retainer for inserting the connecting key is disposed on the pull rod.

[0010] As a preferred embodiment of the present invention, the bottom edge of the top pressure plate is evenly distributed with protruding buckles, and the top end of the side limiting ring is provided with a snap-fit ​​groove that matches the protruding buckles. The top pressure plate is fixed to the side limiting ring by snapping the protruding buckles with the snap-fit ​​groove.

[0011] As a preferred embodiment of the present invention, the inner wall of the side limiting ring is symmetrically provided with guide openings, and the protrusion of the dial plate passes through the guide openings and is connected to the adjustment structure.

[0012] As a preferred embodiment of the present invention, the spring is a compression spring, and the spring is evenly sleeved on the outer side of the top of the disengagement transmission component. The compression spring is made of stainless steel, and its wire diameter, number of coils and free height are adapted to the reset spring force requirements of the clutch. Typically, a compression spring with a wire diameter of 1.5-3mm and a number of coils of 8-15 is selected.

[0013] As a preferred embodiment of the present invention, the arc groove and the arc boss are adapted to each other, and both adopt a 1 / 4-1 / 2 arc structure to ensure the smooth sliding of the dial plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Precise positioning and guidance, and smooth transmission: The arc-shaped groove on the edge of the lever plate matches the arc-shaped boss on the inner wall of the side limiting ring. The lower and upper bosses of the disengagement and engagement transmission components match the first slot of the base plate and the second slot of the clutch fixing sleeve, respectively. At the same time, the guide port of the side limiting ring guides the protrusion of the lever plate, realizing precise positioning of the disengagement and engagement transmission components and the lever plate in both axial and circumferential directions. This completely solves the problem of transmission component offset and jamming, ensuring the smoothness of the clutch disengagement process.

[0016] The components fit together tightly, resulting in high transmission efficiency: the tapered protrusion of the brake part fits precisely with the groove of the clutch engagement component, and the mating surfaces of the clutch engagement component, brake part, and clutch retaining sleeve have a high degree of fit, effectively reducing losses during torque transmission and improving power transmission efficiency; at the same time, the arc-shaped mating structure of the boss and the slot reduces the frictional resistance between components, further ensuring smooth transmission.

[0017] The adjustment structure has good linkage and is easy to operate: The adjustment structure transmits the operating force to the shift plate precisely through the linkage of the pull rod, connecting shaft and transmission plate. The cooperation between the connecting key and the card seat improves the stability of the transmission and reduces the loss of operating force, making the clutch engagement and disengagement operation easier and less prone to loosening or failure after long-term use.

[0018] Easy assembly and disassembly, low maintenance cost: The base plate and side limiting ring are fixed to the upper shell cover by connecting bosses and bolts, and the top pressure plate is snapped with the side limiting ring by a buckle. Each core transmission component adopts a sleeve and snap-fit ​​cooperation method, which eliminates the need for a complicated connection structure, realizes the rapid assembly and disassembly of components, and greatly reduces the later maintenance and repair costs.

[0019] Timely reset and efficient power switching: The compression spring between the disengagement transmission component and the top pressure plate provides continuous axial reset force to the disengagement transmission component, ensuring that the disengagement transmission component can quickly and accurately reset after the clutch disengagement operation is completed, thus improving the timeliness and efficiency of the washing machine's washing and spin-drying mode switching.

[0020] High structural stability and long service life: The connection and fit of each component can ensure uniform stress distribution, avoiding the problem of accelerated wear caused by local stress concentration. At the same time, precise limit guidance reduces collisions and friction between components. All metal parts are treated with anti-rust and anti-corrosion measures, mating surfaces are treated with wear-resistant coatings, and anti-loosening washers are installed at bolt connection points, effectively extending the overall service life of the clutch.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-9 The present invention provides a technical solution:

[0033] A clutch engagement / disengagement gear structure is disclosed, with its core application in the clutch assembly of a pulsator-type fully automatic washing machine. This structure enables precise power switching between washing and spin-drying modes, as well as braking. The overall structure consists of four parts: a basic support component, a limit transmission component, an adjustment drive component, and a reset clutch component. The components are connected using modular snap-fit, sleeve, and bolt fixing mechanisms, balancing structural stability with ease of assembly and disassembly. The specific assembly and connection methods are as follows:

[0034] Assembly of basic support components

[0035] The basic support components include the washing machine clutch body 1, the lower shell cover 2, the upper shell cover 3, the bearing 4, and the output shaft 5. The washing machine clutch body 1 is the core power component. Its top and bottom ends are rotatably mounted inside the central mounting cavity of the lower shell cover 2 and the upper shell cover 3 through high-precision rolling bearings 4. The bearing 4 and the shell cover adopt an interference fit, and the inner side of the bearing 4 is coated with high-temperature grease to ensure the stability of the output shaft 5 of the washing machine clutch body 1 when rotating at high speed and reduce radial runout deviation. The output shaft 5 is an integrally formed structure with the washing machine clutch body 1, extends vertically upward and passes through the subsequent components, and serves as the core carrier for power transmission.

[0036] Assembly and fixing of limit transmission components

[0037] The limiting transmission assembly is the core limiting and guiding component of this structure, including a base plate 6, a side limiting ring 8, a top pressure plate 19, and a lever plate 12. The top end face of the upper shell cover 3 is fixed with a circular base plate 6 by bolts. The side of the base plate 6 has 3-4 sets of connecting bosses 7 evenly distributed around its circumference. The side limiting ring 8 is a cylindrical structure, and a connecting boss 9 is provided on its bottom side corresponding to the position of the connecting boss 7. Both sets of connecting bosses have coaxial mounting holes 10. After passing through the connecting boss 9 and the connecting boss 7 in sequence, the connecting bosses are screwed into the threaded holes of the upper shell cover 3 to achieve rigid fixation of the base plate 6 and the side limiting ring 8. The coaxiality deviation between the two does not exceed 0.05mm.

[0038] The top of the side limiting ring 8 is fixed with a top pressure plate 19 by a snap-fit. The bottom edge of the top pressure plate 19 is evenly distributed with elastic protrusions 20. The top end face of the side limiting ring 8 is provided with a snap-fit ​​groove that matches the protrusions 20. During assembly, the protrusions 20 are aligned with the snap-fit ​​groove and pressed. The elastic deformation of the protrusions 20 is used to achieve snap-fit ​​fixation, forming a closed cylindrical limiting cavity, which provides protection and limiting for the internal transmission components. Two sets of elongated guide openings 11 are symmetrically opened on the inner wall of the side limiting ring 8, which serve as the moving guide channel for the lever 12. At the same time, arc-shaped bosses 35 are evenly installed on the inner wall of the side limiting ring 8. The arc-shaped bosses 35 and the side limiting ring 8 are integrally injection molded or die-cast. Their curvature is 1 / 3 of a circle and the surface is polished.

[0039] The lever 12 is a disc-shaped transmission component, which is movably sleeved on the outer side of the bottom end of the subsequent splitting and engaging transmission component 15. Arc-shaped grooves 34 are evenly distributed on its edge corresponding to the position of the arc-shaped boss 35. The curvature of the arc-shaped grooves 34 is perfectly matched with the arc-shaped boss 35. The two are in clearance fit with a clearance of 0.02-0.03mm to ensure that the lever 12 can slide smoothly along the arc-shaped boss 35. Two sets of protrusions 13 are integrally formed symmetrically on the side of the lever 12. The protrusions 13 pass through the guide opening 11 of the side limiting ring 8 and extend outward to connect with the adjustment structure on the side of the upper shell cover 3. A circular connecting hole 14 is opened inside the end of the protrusion 13, which is the connection node for power transmission. The mating surface of the protrusion 13 and the guide opening 11 is treated with a wear-resistant coating to improve service life.

[0040] Adjust the assembly and linkage of the drive components.

[0041] The adjustment drive assembly includes components such as a U-shaped seat 26, a connecting shaft 28, a transmission plate 29, and a pull rod 32, which are power input components for clutch disengagement. The U-shaped seat 26 is welded and fixed to the side of the upper shell cover 3. The two side walls of the U-shaped seat 26 have coaxial fixing holes 27. The connecting shaft 28 is rotatably installed inside the fixing holes 27 through bearings. The connecting shaft 28 can rotate freely around its own axis, and a sealing ring is provided between it and the fixing holes 27 to prevent moisture and impurities from entering.

[0042] A conductive plate 29 is fixed to the outside of the connecting shaft 28 above the U-shaped seat 26 via a flat key. The conductive plate 29 is a bent metal plate with a cylindrical protrusion 30 extending vertically upward at its top. The protrusion 30 is clearance-fitted with the connecting hole 14 on the protrusion 13 of the lever plate 12. The protrusion 30 is inserted into the connecting hole 14 to achieve linkage between the conductive plate 29 and the lever plate 12. A connecting key 31 is welded to the bottom side of the conductive plate 29. The connecting key 31 is a rectangular protrusion structure and is located on the outside of the U-shaped seat 26. A pull rod 32 is welded to the outside of the connecting shaft 28 inside the U-shaped seat 26. The end of the pull rod 32 away from the connecting shaft 28 is a hand-held operating end. A retainer 33 is located near the connecting shaft 28. The retainer 33 is a groove structure. The connecting key 31 is inserted into the retainer 33 and limited by a retaining spring to ensure synchronous linkage between the pull rod 32 and the conductive plate 29 without transmission gap.

[0043] Assembly and fit of the reset clutch assembly

[0044] The reset clutch assembly is the core component for achieving clutch disengagement and automatic reset. It includes a disengagement transmission component 15, a spring 22, a clutch retaining sleeve 23, a pulley 25, etc. The top of the brake part 36 of the washing machine clutch body 1 is placed in the limiting cavity of the side limiting ring 8. The outer circumferential of the brake part 36 has conical protrusions. The disengagement transmission component 15 is a stepped cylindrical structure with conical grooves inside that match the conical protrusions. The two are in conical surface fit, and the fit surface is finely ground to ensure the stability of torque transmission. The disengagement transmission component 15 is movably sleeved on the outside of the brake part 36. Its bottom outer side is interference-fitted with the shift plate 12. The side of the disengagement transmission component 15 above the shift plate 12 is integrally formed with a limiting ring to axially limit the shift plate 12 and prevent the shift plate 12 from slipping during transmission.

[0045] The bottom end of the disengagement transmission component 15 has four sets of lower protrusions 17 evenly distributed around its circumference. The base plate 6 has corresponding slots 16 that are adapted to the lower protrusions 17. The lower protrusions 17 are inserted into the slots 16 and can slide along the slots. The top end of the disengagement transmission component 15 has four sets of upper protrusions 18 evenly distributed around its circumference. The upper protrusions 18 and the lower protrusions 17 are equidistantly distributed around the circumference of the disengagement transmission component 15, and their cross-sections are all arc-shaped with polished surfaces. The output shaft 5 above the top of the brake part 36 is externally fitted with a clutch fixing sleeve 23. The bottom side of the clutch fixing sleeve 23 has a slot 37 that is adapted to the upper protrusions 18. The upper protrusions 18 are inserted into the slots 37 to achieve linkage between the disengagement transmission component 15 and the clutch fixing sleeve 23.

[0046] A spring 22 is installed between the top end of the disengagement transmission component 15 and the bottom end of the top pressure plate 19. The spring 22 is a stainless steel compression spring with a wire diameter of 2mm, a free height of 30mm, and 10 coils. The spring 22 is evenly sleeved on the outer side of the top end of the disengagement transmission component 15, and its two ends abut against the top end face of the disengagement transmission component 15 and the bottom end face of the top pressure plate 19, respectively, to provide continuous axial return elastic force for the disengagement transmission component 15. A pulley 25 is fixedly installed on the outside of the output shaft 5 above the clutch fixing sleeve 23 by a clamping nut 24. The clamping nut 24 and the output shaft 5 are threaded together. After tightening, the pulley 25 is rigidly fixed. The pulley 25 is the power input component of the washing machine and is connected to the washing machine drive motor through a belt.

[0047] In this embodiment, all metal parts are galvanized or powder coated, providing excellent rust and corrosion resistance; all mating surfaces of snap-fit ​​and socket joints are polished or coated with wear-resistant coatings to reduce friction loss; and all bolted connections are equipped with anti-loosening washers to prevent bolts from loosening due to long-term vibration of the washing machine, thereby extending the service life of the overall structure.

[0048] Work process

[0049] In the actual use of a pulsator-type fully automatic washing machine, the clutch engagement and disengagement gear structure of this invention mainly realizes four core functions: power transmission, washing / spinning mode switching, automatic reset, and braking. The workflow of each function is as follows:

[0050] Conventional power transmission process

[0051] After the washing machine is started, the drive motor drives the pulley 25 to rotate at high speed via the belt. The pulley 25 is rigidly connected to the output shaft 5 via the clamping nut 24, which in turn drives the output shaft 5 to rotate synchronously. The output shaft 5 transmits power to the transmission mechanism inside the washing machine clutch body 1, and then the washing machine clutch body 1 transmits power to the washing machine impeller to achieve normal washing or spin-drying operation. At this time, under the return force of the spring 22, the conical groove inside the disengagement transmission component 15 is tightly fitted with the conical protrusion of the brake part 36. The upper boss 18 is fully engaged with the second slot 37 of the clutch fixing sleeve 23, and the lower boss 17 is partially engaged with the first slot 16 of the base plate 6. The whole is in a linked and fitted state to ensure the continuity of power transmission.

[0052] Washing / spinning mode clutch separation switching process

[0053] When the washing machine needs to switch between washing and spin-drying modes, the lever 32 of the adjustment structure is pulled by the washing machine's actuator or manually. The lever 32 rotates around the axis of the connecting shaft 28. Through the cooperation of the card seat 33 and the connecting key 31, the transmission plate 29 is driven to rotate synchronously around the connecting shaft 28. The protrusion 30 at the top of the transmission plate 29 rotates inside the connecting hole 14 of the dial plate 12, thereby driving the dial plate 12 to rotate circumferentially.

[0054] During the rotation of the lever 12, the arc-shaped groove 34 on its edge slides smoothly along the arc-shaped protrusion 35 on the inner wall of the side limiting ring 8. At the same time, the protrusion 13 of the lever 12 moves axially and circumferentially along the guide port 11, realizing the precise guidance and rotation of the lever 12 without deviation or jamming. The lever 12 drives the disengagement transmission component 15 to rotate circumferentially in sync. The lower protrusion 17 at the bottom of the disengagement transmission component 15 slides along the slot 16 of the base plate 6, and the upper protrusion 18 at the top slides along the slot 37 of the clutch fixing sleeve 23. While rotating circumferentially, the disengagement transmission component 15 moves axially upward along the conical protrusion of the brake part 36, compressing the spring 22 sleeved on the outer side of its top, causing the spring 22 to undergo elastic deformation.

[0055] As the split-drive component 15 moves axially upward, its internal conical groove gradually separates from the conical protrusion of the brake part 36, and the upper boss 18 completely disengages from the slot 37 of the clutch fixing sleeve 23, realizing the separation of the split-drive component 15 from the brake part 36 and the clutch fixing sleeve 23, cutting off the torque transmission between them, and completing the power switching of the washing machine's washing and spin-drying modes. The entire switching process is smooth and without obvious abnormal noise.

[0056] Automatic Reset Procedure

[0057] When the washing machine completes the mode switch and no longer needs to maintain the clutch disengagement state, the pulling force on the pull rod 32 is released. At this time, the compressed spring 22 releases its elastic potential energy, generating a downward axial reset force, which pushes the disengagement transmission component 15 to move axially downward along the conical protrusion of the brake part 36, while simultaneously driving the dial plate 12 to rotate in the opposite circumferential direction.

[0058] The lever 12, through the cooperation of the protrusion 13 and the protrusion 30, drives the transmission plate 29 to rotate in the opposite direction. The transmission plate 29, through the cooperation of the connecting key 31 and the card seat 33, drives the pull rod 32 to rotate in the opposite direction around the connecting shaft 28 until the pull rod 32 returns to its initial position. At the same time, the lower protrusion 17 of the disengagement transmission component 15 re-engages into the slot 16 of the base plate 6, and the upper protrusion 18 re-engages into the slot 37 of the clutch fixing sleeve 23. The conical groove and the conical protrusion of the brake part 36 are tightly fitted again, completing the automatic reset of the overall structure. The reset process is fast, accurate, and without reset deviation, ensuring the stability of the washing machine's subsequent operation.

[0059] Braking process

[0060] When the washing machine needs to stop operating, such as after washing and spin-drying, the brake part 36 of the washing machine clutch body 1 is activated, generating braking torque. The brake part 36 transmits the braking torque to the conical groove of the disengagement transmission component 15, which is in close contact with it, through the conical protrusion on its outer side. The structure of the conical surface contact ensures that the torque transmission is lossless. After receiving the braking torque, the disengagement transmission component 15 transmits the torque to the base plate 6 through the lower boss 17 at the bottom end, and then from the base plate 6 to the side limiting ring 8 and the upper shell cover 3. By using the rigid connection of each component, the braking torque is distributed to the overall basic support component, realizing fast and stable braking, with fast braking response and no braking lag.
