In addition, possessed the compression spring 40 of when dehydration mode is switched, pushing the bottom direction of shaft coupling 15 between the upper side of shaft coupling 15 and the lower bearing 24.
And, with reference to Fig. 2 a to Fig. 4, possesses protrusion 222 on shaft coupling blocking device 22 lateral surfaces, protrusion 222 is between the bracing frame 220 of inserted link 10 and shaft coupling blocking device 22, possessed in the Y-shaped movable rod 12 of protrusion 222 belows and crossed the connecting portion 12a that connects two side levers, giving movable rod 12 when having possessed dehydration between protrusion 222 and the connecting portion 12a is that the extension spring 13 that the hour hands direction is rotated is pressed at the center with steady pin 12b.
In addition, the front end face that pastes mutually of the leading section of movable rod 12 and flange part 152 bottom surfaces of shaft coupling 15 is to be processed into toroidal in order to alleviate frictional force.
On the one hand, shaft coupling 15 is the flange parts 152 that possess on the cylinder body upper end along the radial direction expansion, form the gear teeth 151 that can cooperate along circumferencial direction near flange part 152 upper edge, possessed the sawtooth 150a/150b that can mesh on the inner peripheral surface with the sawtooth on the internal connector 16b upper end outer circumference surface of the sawtooth of formation dehydrating shaft 5 and connector assembly 16 with the gear teeth 221 of shaft coupling blocking device 22.
At this moment, the tooth pitch that is formed on the sawtooth 150a/150b on the body inner peripheral surface of shaft coupling 15 is, internal connector 16b upper end position when shaft coupling 15 descends back and internal connector 16b engagement fully is a benchmark, and upper side sawtooth 150a and lower side sawtooth 150b form different modulus mutually.
That is, the tooth pitch of the sawtooth that forms on the body inner peripheral surface of shaft coupling 15, the internal connector 16b upper end position during with engagement is a benchmark, the sawtooth 150b of its underpart forms bigger modulus.
Particularly, the bottom of carrying out the circular lower side sawtooth 150b that handles is, for can be easily and the sawtooth 161b of internal connector 16b carry out interlock, formation involute profile surface.
In addition, the place that each paddy following and lower side sawtooth 150b of the upper side sawtooth 150a that forms on the shaft coupling 15 body inner peripheral surfaces contacts is in order to shorten rapid end face variation and to increase the ability of bearing twisting stress, to carry out circle and handle.
In addition, on the body lower surface of shaft coupling 15, also can form in order to dwindle the protrusion 154 with rubber ring 18 contacts area.
On the one hand, dehydrating shaft 5 is different with existing dehydrating shaft, and the axial region upper end, bottom that internal diameter is big is inboard inserts in conjunction with the top axial region, and the upper end of bottom axial region is to support the upper bearing (metal) 23 of supporting dehydrating shaft 5.
The mechanism of the clutch mechanism of the present invention of structure is as follows.
At first, be the state that applies the pass of power supply on the clutch motor 6 of not giving before the washing beginning, shaft coupling 15 is kept the state of decline shown in Fig. 2 b.
That is, at this moment, movable piece 9 is on the groove on the inclined plane 801 with lever 8, and shaft coupling 15 is to be in bottom dead centre.
In the above-mentioned state, when clutch motor 6 applies power supply and start clutch motor 6, the driving force of clutch motor 6 sends cam 600 to by driving shaft, cause that by rotatablely moving of cam 600 connecting rod 17 is to clutch motor 6 side shiftings, thereupon, accept the guiding of control lever guide pipe 30, lever is dragged to clutch motor 6 sides.
At this moment, the back-moving spring 14 that is arranged on 30 rearward end of control lever guide pipe is stretched.
On the one hand, the movable piece 9 of contact on the inclined plane 801 of lever 8 is to be tilted face 801 to pin and descend during cam 600 rotation, the state shown in Fig. 2 a, and when cam 600 was in support level, movable piece 9 was in the bottom of the tabular surface 802 of lever 8.
Then, along with the decline of inserted link 10, movable rod 12 is the center with the steady pin 12b of the position, middle part of the bracing frame 220 of the fixing shaft coupling blocking device 22 in perforation bearing housing 20 bottoms, counterclockwise rotates to drawing.
In addition, movable rod 12 is the center with steady pin 12b, and when the counter clockwise direction of drawing was rotated, end in contact was pushed to along dehydrating shaft 5 shaft coupling 15 in flange part 152 bottom surfaces of shaft joint 15 before the movable rod 12 to the axle upper direction.
Thereupon, when finishing the powershift of washing mode, as Fig. 2 a and Fig. 4 diagram, the gear teeth 151 that are formed on shaft coupling 15 upper ends be fixed on bearing housing 20 bottom surfaces on shaft coupling blocking device 22 in the gear teeth 221 that possess be meshed.
And when the gear teeth 151 of shaft coupling 15 were meshed with the gear teeth 221 of shaft coupling blocking device 22, shaft coupling 15 broke away from connector assembly 16, only rotated wash shaft 4 when making rotor 7b rotation.
Promptly, during washing, 15 states that are meshed with the sawtooth of the outer circumference surface of dehydrating shaft 5 of shaft coupling are in out of mesh state with the sawtooth 161b of the internal connector 16b upper end that is engaged on wash shaft 4, and the rotary power of rotor 7b sends impeller 3 to by 4 of wash shaft.
In addition, the gear teeth 151 of shaft coupling 15 are engaged under the state of the gear teeth 221 of shaft coupling blocking device 22, and the rotation that prevents shaft joint 15 is undertaken by the gear teeth 221 of shaft coupling blocking device 22.
Therefore, when switching to washing mode and washing, clutch motor 6 is kept closing state.
Below, the course of action of the clutch mechanism when dehydration is described.
Wash and wash under the state as Fig. 2 a finish after when dewatering, when requiring to switch to the power transmission path of dehydration mode, apply power supply to clutch motor 6 once more, drive the clutch motor, rotating cam 600.
Therefore, when 600 rotations of the cam of clutch motor 6 moved to dehydration location, lever 8 was reset under the recuperability of spring 14 away from clutch motor 6.
Thereupon, contact is shown in Fig. 2 b, when finishing the starting point that resets of lever 8, to be on the groove 800 on the inclined plane 801 that possesses lever 8 at the movable piece 9 of the tabular surface 802 of lever 8 in the washing mode.
When causing that along with lever 8 mobile movable piece 9 rises, relax the compression stress that buffer spring 11 is applied, the inserted link 10 that can the lifting form be provided with along the gathering sill 900 of movable piece 9 also rises thereupon.
Then, along with the rising of inserted link 10, movable rod 12 is the center to connect the steady pin 12b that is provided with on the bracing frame 220 of the shaft coupling blocking device 22 of the bottom that is fixed on bearing housing 20, press drawing (with reference to the clockwise direction rotation of Fig. 2 on a).
In addition, be clockwise on the middle mind-set drawing when rotating as movable piece 12 with steady pin 12b, movable piece 12 front ends support shaft coupling 15 and the power of releasing to the axle upper direction along dehydrating shaft 5 to be eliminated.
When cancellation during to the holding power of the movable piece 12 of shaft coupling 15, shaft coupling 15 is that the recuperability effect according to deadweight and compression spring 40 descends down, and the gear teeth 151 of shaft coupling 15 break away from from the gear teeth 221 of shaft coupling blocking device 22 thereupon.
In addition, when shaft coupling 15 descends fully, the sawtooth 150a/150b of shaft coupling 15 inner peripheral surfaces separately with the internal connector 16b upper end outer circumference surface that is combined in wash shaft 4 on sawtooth 161b and the sawtooth of dehydrating shaft 5 bottoms be meshed, thereupon, when rotor 7b rotated at a high speed, the rotation of the high speed of formation wash shaft 4 and dehydrating shaft 5 was also dewatered.
At this moment, be formed among the sawtooth 150a/150b of inner peripheral surface of shaft coupling 15, when forming bigger modulus with the sawtooth 150b of the part of internal connector 16b engagement, the bottom that is in the sawtooth 150b of the big lower side of tooth pitch has been processed into circle, forms easily with the engagement of the gear teeth 161b of internal connector 16b and separates.
On the one hand, during position when causing that according to the driving of clutch motor 6 washing shaft coupling 15 enters washing in the powershift process of washing mode, the position of engagement of the gear teeth of the gear teeth of shaft coupling blocking device 22 and shaft coupling 15 not to the time, may produce the state of 15 moments of shaft coupling constraint.
That is, shaft joint blocking device 22 is fixed on the invariant position that makes the gear teeth 221 on the bearing housing 20, but shaft coupling 15 rotates simultaneously with dehydrating shaft 5, so the position of the gear teeth changes when stopping.Thereupon, when switching to the washing state, mutual case of collision appears in the mountain peak part that might produce the gear teeth 221 of the mountain peak part of the gear teeth 151 of shaft joint 15 and shaft coupling blocking device 22, and this situation is called the moment restrained condition to shaft coupling 15.
At this moment, shaft joint 15 be in internal connector 16b upper end outer circumference surface on sawtooth 161b also a little the engagement state, therefore rotate simultaneously with internal connector 16b, when the paddy of the mountain of the shaft coupling side gear teeth and shaft coupling blocking device 22 side wheel teeth 221 was met during along with rotation, the gear teeth 151 of shaft coupling 15 and the gear teeth 221 of shaft coupling blocking device 22 were according to the moment restrained condition that meshes naturally under the thrust of the buffer spring 11 that is provided with between movable piece 9 and the inserted link 10 and remove shaft coupling 15.
But, the leading section of the gear teeth 221 that form on the gear teeth 151 that form on the existing shaft coupling 15 and the shaft coupling blocking device 22 forms triangular shaped profile, formation face contact during contact, action when therefore meshing can not form soft, so produces the problem points of friction noise till existing the gear teeth to mesh fully.
Summary of the invention
Technical problem to be solved by this invention is, a kind of shaft coupling engaging structure of automatic washing machine is provided, possesses gear teeth shape, form the line contact at shaft coupling and shaft coupling blocking device by change, action during engagement is soft, the friction noise that produces in the time of can alleviating gear teeth meshing simultaneously.
