Abstract
The utility model provides a main shaft sealing device for a large-size washing machine, comprising a supporting device, sealing medium, an oil feeding hole, a sealing element, etc. A plurality of sealing cavities are arranged in the supporting device, and the semi-solid sealing medium is poured in the sealing cavities through the oil feeding hole. The sealing medium is mixed with a given amount of magnetic powder. The clearance between the supporting device and the main shaft is filled with the magnetic powder and the sealing medium, so the sealing performance of the main shaft is realized.
Description
Technical field
The utility model relates to a kind of sealing device for rotary shaft, particularly leviathan sealing of spindles device.
Background technology
Large-scale vertical washing machine main shaft seal problem is a difficult problem at present, and existing homemade leviathan main shaft seal generally adopts rubber oil sea, and generally be no more than 2 years service life.
The purpose of this utility model is to design a kind of leviathan sealing of spindles device, to solve washing machine main shaft seal problem.
Summary of the invention
The utility model such as Fig. 1 show, are made up of supporting arrangement 1, oil filler point 2, sealing medium 3, seal 4; Have annular seal space 6 in the supporting arrangement 1 and connect firmly on frame 7, sealing medium 3 can be liquid state or semisolid or solid-state, in sealing medium 3, mixed Magnaglo, solid-state sealing medium fusing back is injected in the annular seal space 6 by oil filler point 2, and seal 4 is installed between supporting arrangement 1 and the main shaft 5 and plays sealing function.Annular seal space 6 in the supporting arrangement 1 can have a plurality of, to guarantee sealing effectiveness.
Owing in sealing medium, mixed magnetic material powder, the magnetic material powder that is mixed in the sealing medium just is adsorbed in the gap between supporting arrangement 1 and the main shaft thick and fast together with sealing medium, thereby the outflow of having blocked sealing medium effectively, and do not influence the operating characteristic of main axis rotation, to play the effect of the interior space of sealing and the external space.
The utility model hermetically-sealed construction is simple, practical, and after seal 4 is worn, magnetic material powder will be filled a vacancy therebetween together with sealing medium, also can guarantee its sealing property.
Description of drawings
Fig. 1 the utility model structural representation
Wherein S is the interior space of sealing device, and W is that washing machine is the external space of sealing device.
The specific embodiment
Show as Fig. 1, after butter and di-iron trioxide nanometer powder are fully mixed in 3: 1 ratios, form sealing medium 3, heating makes sealing medium 3 flow in the annular seal space 6 by oil filler point 2 can play sealing function.
