The specific embodiment:
Be according to this invention respective instance in the following content---be used for the detailed description of washing machine clutch.Fig. 1 shows the part longitdinal cross-section diagram that is used for washing machine clutch and connected drive motors according to this invention respective instance.Fig. 2 is the upper and lower part assembly fixture that the dehydrating shaft of Fig. 1 and bearing use when inserting bearing in dehydrating shaft groove (location) position, and pilot bearing shows the figure on the inclined plane of groove (location) position formation when vertically inserting groove (location) position.Fig. 3 is the figure that has enlarged a part of Fig. 2 A.
As depicted in figs. 1 and 2, according to this invention respective instance---be used for washing machine clutch and partly comprise: hollow dehydrating shaft 100 with lower member; The wash shaft 200 of in dehydrating shaft 100, rotating; Be inserted in the bearing 150 between wash shaft 200 and the dehydrating shaft 100; Motor power is optionally passed to the motor of dehydrating shaft 100 or wash shaft 200; Form, be inserted with groove (location) position 141 of bearing 150 in its dehydrating shaft 100 inner cylinder; And the guide plate 142 of the bearing that can prevent to insert distortion.
Above-mentioned dehydrating shaft 100 effects are to rotate sink, it comprises bottom dehydrating shaft 140, this bottom dehydrating shaft 140 is connected direct-connected on the top of sink dehydrating shaft 120, and being connected with the Lower Half of lower inside gear-like cylinder 160. the motor rotatory force being made up of stator 400 and rotor 500 is delivered to top dehydrating shaft 120.
200 effects of above-mentioned wash shaft are to rotate washing flabellum (not shown), and it has comprised direct-connected upper wash axle 210 in the washing flabellum, the conducting tube 230 that is connected with upper wash axle 210, has been connected the lower wash axle that also rotatory force of motor is passed to upper wash axle 210 with conducting tube.
Between above-mentioned top dehydrating shaft 120 and the upper wash axle 210 oilless bearing 180 has been installed.Upper wash axle 210 is when top dehydrating shaft 120 inner rotation, because heat takes place in friction, at this moment the oil of oilless bearing 180 inside overflows between top dehydrating shaft 120 and upper wash axle 210, keeps the slyness of upper wash axle 210 to rotate.
Between the top of the bottom of above-mentioned top dehydrating shaft 120 and cylinder 160 and bottom dehydrating shaft 100, the shell 300 that shields has been installed.
The inner separately top and the bottom bearing 330,340 that supports top and the bottom dehydrating shaft 120,140 that is installed with in above-mentioned shell 300 upper and lowers.
Above-mentioned switchover apparatus has comprised with lower member: the clutch electric machine assembly 600 that power is provided; Along with the mobile up and down sliding coupling 650 of bottom dehydrating shaft 100 outer cylinders; The switching lever 640 that sliding coupling 650 is moved up and down; Connect the connecting ring 630 that switches lever 640 and clutch motor 600.
Said structure, in order to be transformed into dehydration mode, clutch electric machine assembly 600 is pushed connecting ring 630 to the solid arrow direction, makes to switch lever 640 to the rotation of solid arrow direction, and sliding coupling 650 also moves to solid arrow thereupon.At this moment, sliding coupling 650 and 535 couplings of rotor axle bush all pass on dehydrating shaft 100 and the wash shaft 200 rotor 500 revolving forces.
Otherwise in order to be transformed into washing mode, clutch electric machine assembly 600 pulls to the dotted arrow direction to connecting ring 630, makes to switch lever 640 to the rotation of dotted arrow direction, and sliding coupling 650 also moves to dotted arrow thereupon.At this moment, sliding coupling 650 separates with rotor axle bush 535, and rotor 500 revolving forces are only passed on the wash shaft 200.
With reference to Fig. 2 and Fig. 3, use top and the bottom assembly fixture 191,192 above-mentioned bearing 150 to be pressed into groove (location) position 141 of bottom dehydrating shaft 140.
Above-mentioned top assembly fixture 191 has comprised with lower member: steel ball, when bearing 150 is embedded in central protuberance position 191a temporarily, play wheel 151 in the promotion bearing 150; The spring 191c of motive force is provided; Neonychium 191d, it can prevent the damage of bearing when upside is pushed at bearing 150.
When installation possesses the top assembly fixture 191 of said structure and bottom assembly fixture 192, at first bottom dehydrating shaft 140 is embedded into the central protuberance position 192a of bottom assembly fixture, central protuberance position 191a with top assembly fixture 191 embeds bearing 150 again, subsequently bearing 150 is pushed groove (location) position 141 that is embedded into the bottom dehydrating shaft to the direction of arrow and gets final product.
Above-mentioned guide plate 142, downward-sloping and form inclined plane 142 and constitute by groove (location) position 141.
Because the effect on inclined plane 142, bearing are pressed when embedding groove (location) position 141, can slide along 142 of inclined plane, be vertically mounted on groove (location) position 141.
Bearing 150 like this vertically is installed to groove (location) position 141, can guarantee the steel ball 152 of bearing 150 and the strength distributed uniform between foreign steamer 153 and the interior wheel 151, avoids a side stressed excessively; Therefore wash shaft 200 can be rotated unobstructedly in dehydrating shaft 100, has prevented noise and vibrations, and has improved the durability of clutch.
What Fig. 4 showed is the vertical assembly fixture that embeds of dehydrating shaft, bearing, the top and the bottom assembly fixture that uses when bearing is inserted into dehydrating shaft groove (location) position and pilot bearing of Fig. 1.
Fig. 5 is the expanded view of the B part of Fig. 4.
With reference to Fig. 4 and Fig. 5, other examples of guide plate for example, guide plate is pressed into assembly fixture 170 by annular and forms.This is pressed into assembly fixture 170 and pushes when being embedded into groove (location) position 141 at bearing, and bearing 150 is vertically installed.The upside that is pressed into portion 141 has formed the installation groove 141a of institute's depthkeeping degree that can be pressed into assembly fixture 170.
The above-mentioned assembly fixture 170 that is pressed into is considered bearing 150 installation grooves 141 releasings afterwards, is arranged to install the detachable of groove 141a.But,, also can be fixed on and install in the groove 141a being pressed into assembly fixture 170 for the long-term location of bearing after installing 150.Meanwhile, prevent distortion in order more effectively to improve, the inner cylinder that is pressed into assembly fixture 170 has designed the inclined-plane 171 that dips down.
Because of the above-mentioned setting that is pressed into assembly fixture 170, bearing is pressed when embedding groove (location) position 141, and 171 slide along the inclined plane, thereby is installed in groove (location) position 141 by guiding vertically.
When bearing 150 so vertically was installed to groove (location) position 141, the strength distributed uniform between the steel ball 152 of bearing 150 and foreign steamer 153 and the interior wheel 151 had avoided a side stressed excessively.Therefore wash shaft 200 is rotated unobstructedly in dehydrating shaft 100, has prevented noise and vibrations, and has improved the durability of clutch.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within protection scope of the present invention.
