Abstract
The utility model relates to a magnetic soft tooth oil shield seal. The magnetic soft tooth oil shield seal comprises an outer ring, a sealing inner ring and a magnet, wherein the sealing inner ring is arranged within a central hole slot of the outer ring and sleeved together with a rotating shaft; the magnet is arranged within the side end surface of the inner ring close to the axial inner wall of the hole slot of the outer ring; an inverted R-shaped empty slot is formed at the inner wall of the sealing inner ring in contact with the rotating shaft; and a soft tooth is arranged in the empty slot. The magnetic soft tooth oil shield seal provided by the utility model has the advantages of simple structure, good sealing effect and the like; and the axial sealing requirements under the conditions of high temperature and high rotation speed can be satisfied.
Description
Technical field
The utility model relates to a kind of shaft sealer of rotary machine, especially a kind of gentle tooth oil catch sealing of magnetic force that is applicable to rotation axis seal.
Background technique
That generally adopts at present is provided with the axial seal structure, solves the problem of axial seal.Like notification number is that the utility model patent of CN2474813 just discloses a kind of magnetic force zero-g sealing configuration; But this structure is when running shaft is in high-speed and high-temperature; Because it is poor that rising appears in seal ring, makes between running shaft and the seal ring and produce axial clearance, axial leakage phenomenon occurs.
Summary of the invention
The purpose of the utility model provides the gentle tooth oil catch sealing of the magnetic force of realizing axial seal under a kind of high temperature and high pressure environment.
For realizing the foregoing invention purpose; The technological scheme that the gentle tooth oil catch sealing of the utility model magnetic force is adopted for by outer shroud, be arranged in the outer shroud central authorities hole slot and with the sealing of running shaft socket in ring and be arranged at and the interior ring side end face of the axial inwall closing of outer ring aperture groove in magnetite form; Wherein with sealing that running shaft contacts in the ring inwall offer dead slot, be provided with gentle tooth in the dead slot.
After adopting said structure, when running shaft is in when running up state, in running shaft and the sealing between the ring gap become big, but gentle tooth circumferentially extending ejection in the dead slot is accomplished axial seal with gap filling.
As the further improvement of the utility model, be " R " type that is inverted at the dead slot of offering of interior ring inwall.This structure is convenient to gentle tooth and is put into and stretch ejection, is beneficial to storing lubricating oil simultaneously, is convenient to lubricating between gentle tooth and rotating shaft face, is beneficial to the location.
As the further improvement of the utility model, said being inverted " R " type dead slot and the diameter of axle are to becoming 5～10 ° to be obliquely installed.
The utility model has the advantages that: simple in structure, good sealing effect especially can satisfy the axial seal requirement under the high speed conditions of high temperature.
Description of drawings
Fig. 1 is the overall structure schematic representation of the gentle tooth oil catch sealing of the utility model magnetic force.
Fig. 2 is the improvement structural representation of the gentle tooth oil catch sealing of the utility model magnetic force.
Embodiment
Show like Fig. 1; The gentle tooth oil catch sealing of the utility model magnetic force; By outer shroud 1, be arranged in the outer shroud central authorities hole slot and with the sealing of running shaft 4 sockets in ring 2 and be arranged at and the interior ring side end face of the axial inwall closing of outer ring aperture groove in magnetite 3 form; Wherein ring offers " R " type dead slot 5 that is inverted with ring inwall in the sealing that running shaft contact for composite material in the sealing, is provided with the tooth 6 that softens in the dead slot.Said structure can satisfy the axial seal requirement under the high speed conditions of high temperature, good sealing effect.
Show like Fig. 2, can be when as installed, and closely cooperate with rotating shaft with dead slot and the diameter of axle to becoming 5～10 ° to be obliquely installed, because expanded by heating does not appear in interior ring composite material, gentle tooth natural torsion was hidden and was compressed in " R " type dead slot that is inverted this moment.When running shaft turns round, because that rising appears in interior ring composite wood expanded by heating is poor, causes in running shaft and the sealing and produce Spielpassung between the ring, the tooth that softens stretches ejection naturally, and slightly contacts with the rotating shaft outer wall, reaches sealing effect.
Claims (3)
1. gentle tooth oil catch sealing of magnetic force; By outer shroud, be arranged in the outer shroud central authorities hole slot and with the sealing of running shaft socket in ring and be arranged at and the interior ring side end face of the axial inwall closing of outer ring aperture groove in magnetite form; It is characterized in that: offer dead slot with ring inwall in the sealing that running shaft contacts, be provided with gentle tooth in the dead slot.
2. the gentle tooth oil catch sealing of magnetic force according to claim 1, it is characterized in that: the dead slot of offering at interior ring inwall is " R " type that is inverted.
