Tsebo e 'ngoe ka khoele

Tsebo e 'ngoe ka khoele

1. Tlhaloso ea Khoele

Khoele e bua ka sebopeho sa spiral, protrusion e tsoelang pele e nang le karolo e itseng ea sefapano e entsoeng ka holim'a cylindrical kapa conical base. Likhoele li arotsoe ka likhoele tsa cylindrical le likhoele tsa conical ho latela sebopeho sa motsoali;

Ho ea ka boemo ba eona 'meleng oa motsoali, e arotsoe ka likhoele tse ka ntle le likhoele tse ka hare,' me ho ea ka sebopeho sa eona se pota-potileng (sebopeho sa leino), se arotsoe ka likhoele tse khutlo-tharo, likhoele tse mahlakore a mabeli, likhoele tsa trapezoidal, likhoele tse serrated le tse ling. likhoele tse sebopeho se khethehileng.

2、 Tsebo e amanang le eona

Ho sebetsa ka likhoele ke ts'ebetso e tsoelang pele e nang le sebopeho sa leino se boletsoeng se entsoeng hammoho le helix holim'a cylindrical kapa conical. A protrusion e bolela karolo e tiileng mahlakoreng a mabeli a khoele.

E boetse e tsejoa e le meno. Ts'ebetsong ea mochini, likhoele li khaoloa holim'a cylindrical shaft (kapa bokaholimo ba lesoba) ho sebelisoa sesebelisoa kapa lebili le silang.

Ka nako ena, workpiece e potoloha 'me sesebelisoa se tsamaea sebaka se itseng haufi le axis ea workpiece. Matšoao a khaotsoeng ke sesebelisoa holim'a workpiece ke likhoele. Khoele e entsoeng bokaholimong bo ka ntle e bitsoa khoele e kantle. Likhoele tse entsoeng ka holim'a lesoba le ka hare li bitsoa likhoele tse ka hare.

Motheo oa khoele ke helix holim'a axis e chitja. Profaele ea khoele e ka aroloa ka mefuta e fapaneng

Haholo-holo ho na le mefuta e mengata ea li-profiles tsa thread:

Khoele e tloaelehileng (khoele e kgutlotharo): Leino la lona le sebopeho sa kgutlotharo e equilateral, e nang le angle ya leino la 60 degrees. Ka mor'a hore likhoele tse ka hare le tse ka ntle li kenngoe, ho na le lekhalo la radial, le arotsoeng ka likhoele tse mahoashe le tse ntle ho ea ka boholo ba sekontiri.

Khoele ea phala: Sebōpeho sa leino sa likhoele tsa liphaephe tse sa tieang ke khutlo-tharo ea isosceles, e nang le angle ea leino ea likhato tse 55 le huku e kholo e chitja ka holim'a leino.

Litšobotsi tsa sebopeho sa leino la likhoele tsa liphaephe tse tiisitsoeng li tšoana le tsa likhoele tsa liphaephe tse sa tiisitsoeng, empa li leboteng la phala ea conical, e nang le sebopeho sa leino la isosceles trapezoidal le angle ea meno ea likhato tse 30.

Khoele ea trapezoidal: Sebopeho sa leino la eona ke isosceles trapezoid, e nang le leino la leino la likhato tse 30, 'me e sebelisoa haholo ka mekhoa ea sekoti bakeng sa ho fetisa matla kapa ho sisinyeha.

Khoele ea Rectangular: Leino la lona le na le lisekoere, 'me lehlakoreng la leino le lekana le likhato tse 0. E na le ts'ebetso e phahameng ea phetisetso, empa ho nepahala ho tlase ho setsi le matla a motso a fokolang.

Khoele ea Serrated: Leino la lona le sebopeho se sa lekaneng sa trapezoidal, se nang le leqhubu la leino la likhato tse 3 sebakeng sa mosebetsi. Motso oa khoele e ka ntle o na le sekhutlo se seholo se chitja, 'me katleho ea phetisetso le matla li phahame ho feta tsa likhoele tsa trapezoidal.

Ho phaella moo, ho na le likhoele tse ling tse khethehileng tse bōpehileng joaloka V, likhoele tsa Whitney, likhoele tse chitja, joalo-joalo.
