Abstract

The utility model relates to a magnetic machine oil seal which has the same functions as traditional oil seal and filler sealing but has better performance and service life; the magnetic machine oil seal consists of a dynamic ring O-shaped ring, a dynamic ring, a permanent magnet, a static ring, a static ring O-shaped ring and a sealing seat; the dynamic ring and a shaft rotate with the help of the resistance of the dynamic ring O-shaped ring and are sealed at the same time; the static ring and the sealing seat are positioned with the help of the resistance of the static ring O-shaped ring and are sealed at the same time; the dynamic ring and the static ring are combined into a friction pair; when the magnetic machine oil seal works, the dynamic ring and the static ring can be very well jointed with the help of the design magnetic attraction, but the section pressure is much less than that of mechanical sealing; in addition, the structure is very simple, the cost is low and the use is convenient.

Description

Magnetic mechanic oil seal
Technical field
The utility model is a kind of oil sealing, more particularly, is that a kind of performance is better, the magnetic mechanic oil seal that the life-span is longer.
Background technique
The tradition oil sealing has rubber oil sea, labyrinth oil seal and packing seal; they all have the high problem of leak-down rate; oil sealing and packing seal are to axle or axle sleeve serious wear; the linear velocity of using is also very low; life-span is short, leaks when labyrinth oil seal is not only worked, and shuts down also and leaks; and can not be used for vertical structure, linear velocity is also had requirement.
Summary of the invention
The utility model provides a kind of magnetic mechanic oil seal, good seal performance, and to axle or not wearing and tearing of axle sleeve, the life-span is long.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the sealing principle that adopts mechanical seal, entire infrastructure is made up of rotating ring O type circle, rotating ring, permanent magnet, stationary ring, stationary ring O type circle and envelope seat, and the envelope seat can be installed to screw rod by flange flange and need on the apparatus for sealing.The rotating ring of magnetic mechanic oil seal and stationary ring are formed friction pair, the rotating ring inside of making by fabulous SiC of wear resistance or the WC permanent magnet of packing into, stationary ring is made by the good soft magnetic material of wear resistance, uses the sealing of rotating ring O type circle between rotating ring and the axle, seals with stationary ring O type circle between stationary ring and the envelope seat.During work, between rotating ring and the stationary ring by the magnetic pull sealing of well fitting, but face pressure is than little many of mechanical seal, rotating ring O type circle drives rotating ring and rotates with axle in sealing, stationary ring O type circle keeps stationary ring and envelope seat location in sealing, envelope seat available metal or nonmetal rigid construction material are made, and are designed to proprietary flange flange in the capping and are installed in screw rod and need on the apparatus for sealing.
Another kind design as model utility, adopt the sealing principle of mechanical seal, entire infrastructure is made up of rotating ring O type circle, rotating ring, permanent magnet, stationary ring, stationary ring O type circle and envelope seat, and the envelope seat can be installed to screw rod by flange flange and need on the apparatus for sealing.The rotating ring of magnetic mechanic oil seal and stationary ring are formed friction pair, the rotating ring inside of making by fabulous SiC of wear resistance or the WC permanent magnet of packing into, stationary ring is made by the good soft magnetic material of wear resistance, uses the sealing of rotating ring O type circle between rotating ring and the axle, seals with stationary ring O type circle between stationary ring and the envelope seat.During work, between rotating ring and the stationary ring by the magnetic pull sealing of well fitting, but face pressure is than little many of mechanical seal, rotating ring O type circle drives rotating ring and rotates with axle in sealing, stationary ring O type circle keeps stationary ring and envelope seat location in sealing, the external diameter of envelope seat can be designed to be complementary and be bonded and sealed to cooperate with the installation internal diameter of original bearing gland of equipment or packing seal corresponding position pack into.
Usefulness of the present utility model is good seal performance, to axle or not wearing and tearing of axle sleeve, is applicable at a high speed or low speed, and is horizontal or vertical, and simple in structure cheap.
