Abstract

The utility model discloses a waterproof oil seal structure of a washing device. The washing device comprises an outer barrel, an inner barrel, a main shaft, an axle sleeve, a rolling bearing and a bearing seat, wherein, the main shaft penetrates through a back plate of the outer barrel to be fixed on a back plate of the inner barrel, the bearing seat is fixed on the back plate of the outer barrel, and a planar oil seal is arranged between the back plate of the outer barrel and the back plate of the inner barrel and around the main shaft; a sealing seat is arranged on the back plate of the outer barrel and around the main shaft and is fixed on the bearing seat, and three mutually isolated framework oil seals are fixed on the sealing seat; and an oil cavity and a water discharging trough are respectively encircled between the sealing seat and the axle sleeve, the sealing seat and the bearing seat and the sealing seat and the back plate of the outer barrel and on the two opposite sides, wherein, an oil filling hole of the oil cavity is positioned on one side of the bearing seat, and a water outlet opening of the water discharging trough is formed on the other opposite side of the bearing seat. Due to the adoption of the dual waterproof oil seal of the planar oil seal and the framework oil seals, the waterproof oil seal structure of the washing device ensures that the washing water is fully blocked, so as not to infiltrate to the rolling bearing, thereby having good protection action to the rolling bearing.

Description

The dubbin seal structure of washing facility

Technical field

The utility model relates to washing facility, particularly a kind of dubbin seal structure of washing facility.

Background technology

Existing rinsing machine and dry cleaner washing facility, bucket and outer bucket during work, are put into bucket with fabric in all comprising, outer bucket is irritated washings liquid, in order to prevent that washings liquid from infiltrating rolling bearing along main shaft sleeve and making it to damage, waterproof seal need be set, and traditional sealing device or parts are too many, cost is higher, perhaps sealing means is too simple, and sealing effectiveness is relatively poor, haves much room for improvement.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of dubbin seal structure of washing facility is provided, and can guarantee that washings liquid can't infiltrate rolling bearing, and is respond well.

For solving the problems of the technologies described above, the technical solution of the utility model is: the dubbin seal structure that a kind of washing facility is provided, described washing facility comprises outer bucket, interior bucket, main shaft, axle sleeve, rolling bearing, bearing block, plate was fixed on the plate of interior bucket back after wherein main shaft passed outer bucket, bearing block is fixed on the plate of outer bucket back, between outer bucket back plate and the interior bucket back plate, be provided with the plane oil sealing around main shaft; Be provided with seal receptacle around main shaft on the plate of outer bucket back, it is fixed on the bearing block, is fixed with the outside framework oil seal of three spaces on the seal receptacle; Between seal receptacle and axle sleeve, bearing block, the outer bucket back plate, surround oil pocket respectively in relative both sides and the groove that anhydrates, wherein the tank filler sleeve of oil pocket is positioned at a side of bearing block, and the water discharge outlet of the groove that anhydrates is positioned at opposite side relative on the bearing block.

The dubbin seal structure of above-mentioned washing facility owing to adopted the dual waterproof oil sealing of plane oil sealing and outside framework oil seal, has guaranteed that washings liquid can't be infiltrated rolling bearing by complete packing, thereby rolling bearing has been played excellent protection.

Description of drawings

Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.

Fig. 1 be described utility model A-A to cutaway view;

Fig. 2 be described utility model A-A to local amplification view.

The specific embodiment

Referring to Fig. 1-Fig. 2, a kind of dubbin seal structure of washing facility is provided, described washing facility comprises outer bucket 1, interior bucket 2, main shaft 3, axle sleeve 4, rolling bearing 5, bearing block 6, wherein main shaft 3 pass an outer bucket back plate 7 be fixed on the plate 8 of bucket back, bearing block 6 is fixed on the plate 7 of outer bucket back.Between outer bucket back plate 7 and the interior bucket back plate 8, be provided with plane oil sealing 9 around main shaft 3, this is the first road waterproof oil sealing that this structure is set up, and during the washing facility operation, washings liquid is come by plane oil sealing 9 and main shaft 3 packings.Be provided with seal receptacle 10 around main shaft 3 on the plate 7 of outer bucket back, it is fixed on the bearing block 6, be fixed with the outside framework oil seal 11 of three spaces on the seal receptacle 10, this is the second road waterproof oil sealing that this structure is set up, when contingency has fragmentary washings liquid to pass through plane oil sealing 9, when waiting to infiltrate the sealing lip of outside framework oil seal 11 and the gap between the axle sleeve 4, these three outside framework oil seals 11 can guarantee the complete packing to washings liquid.By the repeatedly packing of above-mentioned dual waterproof oil sealing, washings liquid can't infiltrate in the rolling bearing 5 at all, thereby avoids rolling bearing 5 to be subjected to water erosion and damage.Between seal receptacle 10 and axle sleeve 4, bearing block 6, the outer bucket back plate 7, surround the oil pocket 12 and the groove 13 that anhydrates respectively in relative both sides, wherein the tank filler sleeve 14 of oil pocket 12 is positioned at a side of bearing block 6, and the water discharge outlet 15 of the groove 13 that anhydrates is positioned at opposite side relative on the bearing block 6.In oil pocket 12, add lubricating oil by tank filler sleeve 14, can make the contact-making surface between outside framework oil seal 11 and the axle sleeve 4 form oil film, avoid causing sealing lip heating, wearing and tearing bearing 5 and outside framework oil seal 11 lubricates.The anhydrate effect of groove 13 is to make by the fragmentary washings liquid of plane oil sealing 9 and outside framework oil seal 11 finally to discharge from water discharge outlet 15 through the groove 13 that anhydrates.

The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
