Abstract
The utility model discloses a seal dust proof structure used for a decelerating clutch of a washing machine, which comprises an output axis and a large water seal, wherein, the large water seal is installed on the output axis through the seal lip; in addition, the utility model also comprises a protective sleeve, and the protective sleeve is arranged on the seal lip and connected with the output axis through tight fit. During the working, the protective sleeve can isolate the foreign matter such as gritty dust outside the sealed large water seal through the water flow produced during the rotation, the protecting problem of the sealed large water seal can be effectively solved, the failure and water leakage phenomenon of the sealed large water seal between the seal lip and the output axis caused by the wearing of the gritty dust can be avoided, and the service life of the decelerating clutch and the washing machine can be extended.
Description
Technical field
The utility model relates to a kind of Sealing Technology of decelerating clutch of washing machine, relates in particular to a kind of sealing and dustproof structure of decelerating clutch of washing machine.
Background technology
In existing pulsator washing machine technology, speed-reducing clutch is a vitals in the washing machine.Speed-reducing clutch is connected the outer barrel of washing machine bottom, and its output shaft is in the water when work all the time, and the seal protection of whole speed-reducing clutch is to rely on the big water seal of sealing that is installed on the output shaft to realize.Yet, washing machine when work clothing may be stained with sand dust or other foreign matters, because output shaft is a rotation work, so sand dust etc. is easy to involve in the sealing lip of the big water seal of sealing, thereby aggravated the wearing and tearing between sealing lip and the output shaft, caused the big water seal of sealing to lose efficacy and leak.And the water of trace leaks into by water seal on the bearing and other parts of speed-reducing clutch the inside, thereby causes speed-reducing clutch to damage in the operating period, has influenced the service life of washing machine.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; provide a kind of and can effectively protect big water seal, prevent the sealing and dustproof structure of the decelerating clutch of washing machine of its wearing and tearing infiltration; to guarantee the sealing of speed-reducing clutch, prolong the service life of washing machine to greatest extent.
The purpose of this utility model is achieved by the following technical programs:
The sealing and dustproof structure of a kind of decelerating clutch of washing machine that the utility model provides comprises output shaft and big water seal, and described big water seal is installed on the output shaft with its sealing lip; In addition, also comprise protective jacket, this protective jacket is arranged on the sealing lip, and is connected with the output shaft close-fitting.During work, the current that produce when protective jacket passes through to rotate will be isolated in outside the big water seal of sealing the foreign matters such as sand dust that damage sealing function are arranged, and avoid sand dust to involve in sealing lip, solve the protection problem that seals big water seal effectively.
The utility model can be taked following further measure: described protective jacket is a protective cover, and its top is sleeve, and the bottom is overhanging inclined-plane downwards; Described protective cover is by its sleeve and output shaft interference fit, and its inclined-plane covers on the sealing lip outside.The inclined-plane of protective cover has the effect of dust-separation water conservancy diversion, can prevent that foreign matters such as sand dust are involved in sealing lip.In addition, described protective jacket also can be protective ring, and its outside is overhanging cambered surface; Described protective ring is inboard and output shaft interference fit by it, and its outside cambered surface retaining is on sealing lip.Like this, by the barrier effect of protective ring, under the flow action that produces when rotating, foreign matters such as sand dust are isolated in outside the big water seal of sealing.
The utlity model has following beneficial effect: foreign matters such as sand dust can be isolated in outside the big water seal of sealing; solved the protection problem that seals big water seal effectively; the phenomenon of having avoided the wearing and tearing between sealing lip and the output shaft and having caused the big water seal of sealing to lose efficacy and leak has prolonged service life of speed-reducing clutch and washing machine.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of one of the utility model embodiment;
Fig. 2 is the structural representation of middle protective cover embodiment illustrated in fig. 1;
Fig. 3 is two the structural representation of the utility model embodiment;
Fig. 4 is the structural representation of middle protective ring embodiment illustrated in fig. 3.
Among the figure: output shaft 1, protective jacket 2, protective cover sleeve 21, protective cover inclined-plane 22, protective ring cambered surface 23, protective ring inboard 24, big water seal sealing lip 3, clutch housing 4, bearing 5
The specific embodiment
Embodiment one:
Illustrated in figures 1 and 2 is one of embodiment of the present utility model.As shown in Figure 1, comprise output shaft 1, big water seal, protective jacket 2 and clutch housing 4, big water seal is installed on the clutch housing 4, and is installed on the output shaft 1 with its sealing lip 3, and protective jacket 2 is arranged on the sealing lip 3, and is connected with output shaft 1 close-fitting.
As depicted in figs. 1 and 2, protective jacket 2 is a protective cover, and its top is sleeve 21, and the bottom is overhanging inclined-plane 22 downwards.Protective cover is by its sleeve 21 and output shaft 1 interference fit, and its inclined-plane 22 covers on sealing lip 3 outsides, prevents that the sand dust a chain for binding criminals is poly-in the above.Protective cover all covers the sealing lip of big water seal, and the current that produce during by rotation will be isolated in outside the big water seal of sealing the foreign matters such as sand dust that damage sealing function are arranged, and prevent to enter speed-reducing clutch and damage bearing 5 and other parts.
Embodiment two:
Fig. 3 is two of embodiment of the present utility model with Figure 4 shows that with embodiment one difference: protective jacket 2 is protective ring, and as shown in Figure 3 and Figure 4, its outside is overhanging cambered surface 23.Protective ring is by its inboard 24 and output shaft 1 interference fit, and its outside cambered surface 23 retainings are on sealing lip 3.Like this, by the barrier effect of protective ring, under the flow action that produces when rotating, foreign matters such as sand dust are isolated in outside the big water seal of sealing.
