Embodiment
The utility model describes in various embodiments' mode with reference to the accompanying drawings.In Figure of description, the element with similar structure or function will represent with identical component symbol.Component sizes in accompanying drawing and feature just for convenience of explanation with disclose each embodiment of the present utility model, be not to carry out to the utility model the explanation of exhaustive, neither limit scope of the present utility model.
Fig. 1 has set forth a schematic structure that is applied to the water pump of dishwasher according to the utility model embodiment.In this embodiment, drive motor 10 is connected with water pump volute (scheming not shown) by sliding bearing 20.The output shaft drives impeller 30 of drive motor 10 is rotated, and impeller 30 comprises four blades 32, and described blade 32 coordinates water pump to go out with water pump volute (scheming not shown).
Fig. 2 further shows the sectional structure of water pump part assembly.The output shaft 12 of drive motor 10 is connected with impeller body 30 through sliding bearing 20.Wherein, output shaft 12 is connected with axle sleeve 34 close-fittings, forms multiple chambers, in order to hold multiple balls 36 between axle sleeve 34 and impeller 30 wheel hubs 31.Baffle ring 50 forms enclosed space by the first seal ring 60 and the second seal ring 40 with impeller 30 wheel hubs 31, this enclosed space inside holds ball 36 and axle sleeve 34, is filled with lubricant grease simultaneously and produces lubricated with the contact between ball and axle sleeve, ball and impeller body.
Simultaneously with reference to Fig. 2, Fig. 3 and Fig. 4.When drive motor 10 starts, the axle sleeve 34 being connected with live axle 12 close-fittings rotates thereupon, under original state, between the driving gear 342 of axle sleeve 34 and ball 36, has gap, and therefore motor can start easily.Live axle 12 is rotated further, and the driving gear 342 of axle sleeve 34 contacts ball 36, thereby promotes ball moving, and ball 36 and then the passive tooth 302 promoting on impeller body 30 are rotated.
At the electric motor starting initial stage, output shaft 12 and the first seal ring 60 relatively rotate.In the time that impeller 30 rotates together along with motor output shaft, output shaft 12 is synchronizeed rotation with the first seal ring 60.Baffle ring 50 outer surfaces are tightly connected with impeller body 30 by the second seal ring 40, and internal surface is connected with output shaft 12 by the first seal ring 60.Preferably, baffle ring 50 is established groove near the surface of motor output shaft, and the outer ring part 62 of seal ring 60 is contained in described groove.Baffle ring 50 is established groove equally away from the surface of motor output shaft 12, and the second seal ring 40 is contained in this groove in order to seal the gap between described baffle ring and wheel hub 31.
In a preferred embodiment, the first seal ring 60 is made up of silicone rubber, and the second seal ring 40 is made up of ethylene propylene diene rubber.
Fig. 5 and Fig. 6 show the concrete structure of the first seal ring 60 according to embodiment of the utility model.The first seal ring comprises outer ring part 62 and inner round portion 63, between outer ring part 62 and inner round portion 63, forms groove 68.The external frame of outer ring part 62 is the arc of axially middle two ends evagination to axial, thereby the radial thickness of outer ring part 62 is reduced toward two ends gradually from middle.Inner round portion 63 comprises the first lug boss 64 and the second lug boss 66.Referring to Fig. 4, the first lug boss 64 and the second lug boss 66 along seal ring perpendicular to radially analysing and observe V-shaped arrangement in direction in its circumferential axial cross section direction.Between the first lug boss 64 of outer ring part 62 and inner round portion 63 and the second lug boss 66, forming respectively groove 68, two grooves 68 keeps at a certain distance away vertically.Outer ring part 62 and inner round portion 63 are formed in one.The first lug boss 64 of inner round portion 63 and the second lug boss 66 and live axle 12 to be sealed form apart from one another by the first surface of contact and the second surface of contact, that is to say, formed two-layer sealing.
The outer ring part 62 and the inner round portion 63 that those skilled in the art will appreciate that the first seal ring 60 can be separately made equally, then assemble.
So far, the utility model has carried out sufficient description to seal ring and water pump, contrasts by experiment, uses the water pump of same specification, uses the seal ring of the utility model announcement, can greatly improve the sealability of water pump.Because the first lug boss of seal ring and the second lug boss and output shaft form two-layer sealing, extraneous water is difficult to enter the holding space of impeller body inside, ensures that water pump moves and can not produce noise within the longer time; Reduce the required pressure minimum being applied on seal ring simultaneously, reduced manufacture cost.
Those skilled in the art will appreciate that the seal ring that the utility model discloses not only can be applied on the water pump of dishwasher, can be applied in the equipment that other need to be carried water, for example washing machine or other industrial washing equipment equally.Same, this connecting tube can be applied in the conveying of other liquid, as the oil-fired system of boats and ships or lubricating oil system etc.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence; can make various changes or modifications to these mode of executions; for example; this technological scheme can be applied in nearly all equipment that need to transmit liquid; because equipment is different; the fastening means of corresponding connecting head has larger difference, but these changes and amendment all fall within the scope of protection design of the present utility model.
