Abstract
The invention relates to a magnetic soft gear oil-shield seal comprising an outer ring, a seal inner ring arranged in a center hole groove in the outer ring and connected with a rotary shaft in a sleeved mode and a magnet arranged in the side end face of the inner ring, wherein the side end face of the inner ring is attached to the axial inner wall of the center hole groove of the outer ring. A reversely-arranged R-typed hollow groove is formed in the inner wall of the seal inner ring contacting with the rotary shaft. A soft gear is arranged in the hollow groove. The magnetic soft gear oil-shield seal has the advantages of being simple in structure and good in seal effect and the like, and can meet axial seal requirements under conditions of a high temperature and a high rotating speed.
Description
Technical field the present invention 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 generally adopts at present arranges axial seal structure, solves the problem of axial seal.The utility model patent that is CN2474813 as notification number 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 seal ring occurs rising poor, make between running shaft and seal ring and produce axial clearance, axial leakage phenomenon appears.
Summary of the invention the purpose of this invention is to provide 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 achieving the above object, the technological scheme that the gentle tooth oil catch sealing of magnetic force of the present invention is adopted for by outer shroud, be arranged in outer shroud central authorities hole slot and with the sealing of running shaft socket in ring and the magnetite that is arranged in interior ring side end face with the axial inwall closing of outer ring aperture groove form, wherein with sealing that running shaft contacts in the ring inwall offer dead slot, be provided with gentle tooth in dead slot.
After adopting said structure, when running shaft is in when running up state, in running shaft and sealing, the ring gap becomes large, but in dead slot, gentle tooth circumferentially extending ejects, and gap filling is completed axial seal.
As a further improvement on the present invention, the dead slot of offering at interior ring inwall is " R " type that is inverted.This structure is convenient to gentle tooth and is put into and stretch ejection, is beneficial to simultaneously storage lubricant oil, is convenient to lubricating between gentle tooth and rotating shaft face, is beneficial to the location.
Further improve as of the present invention, described being inverted " R " type dead slot radially becomes 5～10 ° to be obliquely installed with axle.
Advantage of the present invention is: 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 diagram of the gentle tooth oil catch sealing of magnetic force of the present invention.
Fig. 2 is the improvement structural representation of the gentle tooth oil catch sealing of magnetic force of the present invention.
Embodiment such as Fig. 1 show, the gentle tooth oil catch sealing of magnetic force of the present invention, by outer shroud 1, be arranged in outer shroud central authorities hole slot and with the sealing of running shaft 4 sockets in ring 2 and the magnetite 3 that is arranged in interior ring side end face with the axial inwall closing of outer ring aperture groove form, wherein in the sealing, ring is composite material, offer with ring inwall in sealing that running shaft contacts " R " type dead slot 5 that is inverted, be provided with gentle tooth 6 in dead slot.Said structure can satisfy the axial seal requirement under the high speed conditions of high temperature, good sealing effect.
Show as Fig. 2, can radially become 5～10 ° to be obliquely installed on dead slot and axle when as installed, and closely cooperate with rotating shaft, because expanded by heating does not appear in interior ring composite material, gentle tooth natural torsion, be hidden and be compressed in " R " type dead slot that is inverted this moment.When running shaft turns round, because interior ring composite wood expanded by heating occurs rising poor, cause in running shaft and sealing and produce Spielpassung between ring, gentle tooth stretches ejection naturally, and slightly contacts with the rotating shaft outer wall, reaches sealing effect.
