Abstract

The invention relates to an eccentric spherical externally-conical sealing structure for engine pipeline. The eccentric spherical externally-conical sealing structure comprises a first guide pipe, a flat-pipe nozzle, an additional nut, an external conical connector and a second guide pipe. One end of the external conical connector is connected with one end of the flat-pipe nozzle, and the other end of the external conical connector is fixedly connected with the second guide pipe. The other end of the flat-pipe nozzle is fixedly connected with the first guide pipe. The additional nut is arranged at one end of the flat-pipe nozzle in the external conical connector and fitted with an outer thread of the external conical connector through an inner thread in a screw mode, thus the external conical connector and the flat-pipe nozzle are fixedly sealed. The eccentric spherical externally-conical sealing structure has the advantages that an eccentric spherical structure is adopted to lead to small weight, and a linear sealing structure is adopted to lead to good sealing effect; in a work environment, by a sealing line formed by the eccentric sphere and an inner conical surface, oil leakage probability is low, and maintainability is good; meanwhile a spherical design is adopted in the sealing structure, leading to effective repairability.

Description

A kind of for motor eccentric spherical outer cone pipe sealing structure
Technical field
The present invention relates to a kind of for motor eccentric spherical outer cone pipe sealing structure.
Background technique
At present, the development trend of domestic and international advanced motor is to improve constantly thrust weight ratio, require part reliability, maintainability higher simultaneously, and improve motor thrust weight ratio the most effectively one of means be component meeting outside function and other require, reduce to greatest extent weight.
Engine pipelines is for the transmission of fluid, gas, and the weight of pipeline, in controlling, ensure the sealability of pipeline.Main spherical linear sealing structure, the cone match profile sealing configuration of adopting.Semi-sphere type linear sealing sealing structure good reliability, conical surface sealing structure oil spill rate is low more than 70% relatively, and after its sphere is impaired, the reparation of sphere is good, but weight is heavier; The surface seal structure of cone match is lightweight, but sealing effect is poor, after the conical surface is impaired, is difficult to repair.
For above present situation, need a kind of eccentric spherical outer cone Novel pipeline sealing configuration of design, in alleviating pipe weight, ensure the sealing reliability of pipeline, improve the assembling of pipeline, reparation property.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of for motor eccentric spherical outer cone pipe sealing structure, solves the deficiencies in the prior art.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of for motor eccentric spherical outer cone pipe sealing structure, comprise outer the first conduit, flat ozzle, caption nut, taper joint, the second conduit; One end of described outside cone joint is connected with one end of described flat ozzle; The other end of described outside cone joint is fixedly connected with described the second conduit; The other end of described flat ozzle is fixedly connected with described the first conduit; Described caption nut is flat ozzle one end in outside cone joint, is tightened and coordinates with outside cone joint outside thread by internal thread, plays the effect of external cone joint and flat ozzle fixing seal.
The invention has the beneficial effects as follows: for motor eccentric spherical outer cone pipe sealing structure, adopt eccentric spherical structure, weight is lighter, adopts the structural type of linear sealing, and sealing is better; The potted line that eccentric spherical and inner conical surface form is under working environment, and the probability that leakage of oil occurs is low, has good maintainability; In sealing configuration, adopt sphere design simultaneously, there is good recoverability.
Further: between the other end of described outside cone joint and described the second conduit, to be fixedly connected with by screw thread; Between the other end of described flat ozzle and described the first conduit, be fixedly connected with by screw thread.
Further: between the other end of described outside cone joint and described the second conduit, to be fixedly connected by welding; Between the other end of described flat ozzle and described the first conduit, be fixedly connected by welding.
Further: described outside cone joint fitting surface adopts eccentric sphere male cone (strobilus masculinus).
Further: described flat ozzle is wimble structure in 75 °; Eccentric sphere male cone (strobilus masculinus) in outside cone joint coordinates formation potted line with 75 ° of inner cones in flat ozzle, play the seal action to two connecting pipelines.
