Rialacha roghnúcháin le haghaidh gabhálais mara

The role of marine accessories should be support, that is, literally used to support the shaft, but this is only part of its role, the essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft. The automatic selection of bearings is included. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The motor cannot work at all without bearings. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the role of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this effect, good lubrication must be achieved on the bearings of the high-speed shaft. Some bearings are already lubricated, which are called pre-lubricated bearings. Most bearings must have lubricating oil. When running at high speeds, friction will not only increase energy consumption, but even more frightening is that it is easy to damage the bearings. The idea of turning sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.

Éilíonn an próiseas spraeála teirmeach an trealamh ar fad a dhíchóimeáil agus éilíonn sé go leor acmhainní daonchumhachta agus ábhartha. Tá gá le meaisínithe sa phróiseas deisiúcháin spraeála teirmeach. Mar gheall ar an trealamh mór, tá ceanglais imthacaí mara le haghaidh deileanna an-ard freisin. Tá cruinneas deisiúcháin ard ag an bpróiseas deisiúcháin spraeála teirmeach, ach tá sé deacair trealamh mór a dheisiú agus ní féidir é a dheisiú ar an láthair, rud a fhágann go bhfuil tréimhse deisiúcháin fada agus costais deisiúcháin arda, rud nach bhfuil inghlactha go minic d'fhiontair. Tá an fhadhb ag an bpróiseas próiseála agus deisiúcháin meaisín táthú deisiúcháin traidisiúnta freisin nach féidir an deisiú a chríochnú ar an láthair, tá an timthriall deisiúcháin fada, tá an costas iomlán ard, agus beidh an múchadh fadtéarmach agus an múchadh táirgthe ina chúis le caillteanais eacnamaíocha ollmhóra. fiontar. Cibé an spraeáil theirmeach nó teicneolaíocht próiseála meaisín táthú deisiúcháin é, tá fadhb ann maidir le tiúchan strus teirmeach le linn an phróisis deisiúcháin, rud a fhágann go bhfuil an seafta dífhoirmithe nó go bhfuil baol folaithe briste seafta ann.

Since the lubrication surface of the intermediate bearing is not absolutely smooth, there are various rough peaks of different heights. Therefore, the lubrication status of the intermediate bearing can be judged objectively by the Z small film thickness ratio Hm. The Z small film thickness ratio Hm is defined as the ratio of the Z small oil film thickness of the intermediate bearing to the comprehensive roughness of the two lubricating surfaces, which is dimensionless. Generally speaking, when the Z film thickness ratio is Hm>>3, it indicates that the intermediate bearing has better lubrication performance. The marine intermediate bearing is in a full-film fluid lubrication state, that is, the lubricating oil film fills the gap between the outer surface of the journal and the inner surface of the bearing bush, and the two lubricating surfaces It is completely separated by the oil film and no contact occurs.

Is féidir le húsáid na n-ábhar ilchodach polaiméire caighdeánach le haghaidh deisiúcháin caillteanas na gcostas breise a laghdú go maith, agus tá an t-am deisiúcháin gearr agus tá an costas deisiúcháin íseal. Deisiúchán ar an láthair, próiseas simplí, ní gá go leor daonchumhachta agus acmhainní ábhartha a infheistiú, éifeachtacht chothabhála a fheabhsú go mór agus am neamhfhónaimh a ghiorrú

Is cineál imthacaí é imthacaí idirmheánacha, a úsáidtear go forleathan i dtrealamh meicniúil. Is é an t-imthacaí idirmheánacha príomh-aonad tacaíochta an chórais seaftaithe loinge's, agus iompraíonn sé ualach réasúnta mór le linn an phróisis oibre. Cuirfidh feidhmíocht an imthacaí idirmheánach isteach go díreach ar fheidhmíocht dhinimiciúil an chórais tiomána loinge' Mar sin, déantar anailís feidhmíochta lubrication an imthacaí idirmheánacha chun stádas lubrication an imthacaí a thuar go héifeachtach, agus déantar paraiméadair an struchtúir imthacaí a bharrfheabhsú de réir na gceanglas dearaidh agus na torthaí anailíse chun friotaíocht frithchuimilte an imthacaí idirmheánacha a laghdú, an t-imthacaí a laghdú. creathadh agus torann an chórais seafta, agus feabhas a chur ar an tarchur seafta Tá tábhacht mhór ag baint le héifeachtacht agus iontaofacht, caitheamh ábhair a laghdú agus saol seirbhíse a leathnú.
