Abstract
The utility model aims to provides a combined washing machine oil seal with high reliable tightness and self lubrication, which includes an inner oil seal and an outer oil seal; both the inner oil seal and the outer oil seal include a framework and a seal; the framework of the outer oil seal is in ''pi'' shape and that of the inner oil seal is in L shape; the vertical surface of both oil seals match well; the seal of the outer oil seal is provided with a dust proof device. The combined washing machine has highly reliable tightness, self lubrication function, long service life and is widely applicable in the sealing field of washing machines.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically, relates to the sealing two media oil used on a kind of washing machine running shaft and the seal arrangement of water.
Background technique
Washing machine oil sealing of the prior art all is the oil sealing of a monomer, primary seal lip and secondary sealing lip are arranged, the reliability of its sealing is lower, its seal only depends on interference fit to seal with the side that the seat hole contacts, the reliability of sealing is also lower, and it does not have self-lubricating property, and the frictional ratio between oil sealing and the axle is severe, and this has just shortened the working life of oil sealing.
Summary of the invention
The utility model aims to provide a kind ofly has highly reliable sealing, and has the combined type washing machine oil sealing of self lubricity.
The technical solution of the utility model is achieved in that it comprises inner oil seal and outer oil seal, and inside and outside oil sealing all comprises skeleton and seal, and the skeleton of outer oil seal is " Γ " type, and the skeleton of inner oil seal is " L " type, and its vertical plane is worked in coordination.The inner oil seal seal is provided with primary seal lip, also is provided with spring groove on the seal, and the banding spring is set in the spring groove.The external sealed body is provided with a working surface secondary sealing lip parallel with the working surface of the primary seal lip of inner oil seal.The contacted one side of the seal of inner oil seal and outer oil seal is provided with the mazy type ripple struction.The annular cavity of lubricating grease is held in inner oil seal and outer oil seal formation one.The seal of outer oil seal is provided with dust guard.The dust guard of outer oil seal is the above dustproof skirt of annular wave of circle of two on the seal or two circles.The arranged outside of the seal of the corresponding inner oil seal of outer oil seal has the mazy type ripple struction.
Description of drawings
Fig. 1 is the sectional drawing of user mode of the present utility model.
Embodiment
As shown in Figure 1, combined type washing machine oil sealing of the present utility model, form by inner oil seal 5 and outer oil seal 7, inner oil seal 5 and outer oil seal 7 combination backs and running shaft 1 common composition one hold the annular cavity 11 of lubricating grease, the one side that contacts with outer oil seal 7 of inner oil seal seal is provided with mazy type ripple struction 6, and outer oil seal 7 also is provided with mazy type ripple struction 8 with the one side that seat hole 9 contacts.The effectively low intrusion of having avoided dust of the dustproof skirt 10 of the waveform that is provided with on the outer oil seal 7.Main lip 3 back sides of inner oil seal 5 are provided with banding spring 4.
State after combined type washing machine oil sealing of the present utility model assembles as shown in Figure 1, after inner oil seal 5 and outer oil seal 7 combinations, inner oil seal 5 is provided with spring groove, banding spring 4 is set in the spring groove, the setting of banding spring 4 makes oil sealing tightr with combining of running shaft 1, a sealing lip 2 of the main lip 3 of inner oil seal 5 and outer oil seal 7 closely contacts with the running shaft 1 of washing machine, form the airtight chamber 11 of an annular between the main lip 3 of inner oil seal 5 and the sealing lip 2 of outer oil seal 7 and the running shaft 1, hold lubricating grease in the chamber 11, oil sealing in use, these lubricating grease just play the effect of lubrication oil seal and running shaft 1, greatly reduce the friction factor between oil sealing and the running shaft 1 like this, prolonged the working life of oil sealing.Take interference fit between inner oil seal 5 and the outer oil seal 7, the seal at the surface of contact place of inner oil seal 5 and outer oil seal 7 is set to maze-type structure 6, the seal at the surface of contact place in external sealed body and seat hole 9 also is set to maze-type structure 8, the maze-type structure at this two place makes inside and outside oil sealing be easy to assembling, outer oil seal 7 cylindrical mazy type ripple structions 8 make oil sealing be easy to the seat hole 9 assembling and sealing, prolonged the working life of oil sealing, the setting of mazy type ripple struction also makes You Heshui all be difficult for oozing out or infiltrating from surface of contact.On the seal, also be provided with corrugated dustproof skirt 10 outside, played the effect of end face seal, avoided the intrusion of dust effectively.
The sealing reliability of combined type washing machine oil sealing of the present utility model is than higher, and has self-lubricating function, and the life-span is long, can be extensive use of the field of sealing technology with washing machine.
