Mekhoa ea Cut Trapezoidal Thread

Khoele ea Trapezoidal ke khoele ea phetisetso e sebelisoang haholo, e sebetsoang haholo ke lisebelisoa tsa mochini oa CNC. Ka lebaka la litlhoko tse phahameng tsa ho nepahala bakeng sa likhoele tsa trapezoidal, the ts'ebetso ea machining e tla ba thata le ho feta ka lebaka la ho nepahala le mabaka a mang. Mathata a mantlha e tla ba a bora kapa a ho phunya. Haeba sesebelisoa se senyehile, mochini o tla senyeha. Empa ha feela tlhahlobo ea mahlale a machining e utloahala, ho sebelisoa mekhoa e metle ea ho sebetsa, 'me ho sebelisoa litaelo tse nepahetseng tsa mananeo, likhoele tse tšoanelehang tsa trapezoidal li ka etsoa.

Ho bohlokoa ho qala. Haeba o batla ho etsa khoele e ntle ea trapezoidal, o hloka ho tseba ho bala khoele ea trapezoidal.

Leino la meno: 30 ° e boletsoeng maemong a China, sekontiri se laoloang ke maemo a khoele.

Bophara ba Crest: f = 0.366P.

Bophara ba alveolar tlase: w = 0.366P-0.536cyc

Khoele ea ka ntle ea trapezoidal: bophara bo boholo (bolelele ba lebitso) d; bophara bo bohareng d2 = d-0.5P; bophara bo nyane d3 = d-2h3; bophahamo ba leino: h3 = 0.5P + αc

Khoutu ea khoele ea trapezoidal: Khoutu ea khoele ea trapezoidal e emeloa ke tlhaku "Tr" le bophara ba lebitso x sekhahla, yuniti ke mm. Khoele e letsohong le letšehali e hloka ho tšoauoa ka "LH" kamora ho bonts'a boholo, mme khoele ea letsoho le letona ha e hloke ho tšoauoa.

Tloo ka kotloloho ho bohlokoa-CNC koloi G76 e ommeng khoele ea trapezoidal.
