Ngā Āhuatanga Hanganga o ngā Mekameka Roera Pitch-Rua

Ngā Āhuatanga Hanganga o ngā Mekameka Roera Pitch-Rua

I roto i te rāngai tuku me te kawe waka ahumahi, nā te mea he ngāwari ki te urutau ki ngā tawhiti pokapū nui me te iti o te ngaronga kawenga, kua noho ko ngā mekameka roera takirua hei wāhanga matua o ngā mīhini ahuwhenua, te kawe waka maina, me ngā taputapu ahumahi māmā. He rerekē ki ngā mekameka roera tuku iho, ko tō rātou hoahoa hanganga ahurei te mea e whakatau tika ana i tō rātou pumau me te whai huatanga i ngā tawhiti roa. Ka whakaratohia e tēnei tuhinga he tātaritanga hōhonu mō ngā āhuatanga hanganga omekameka roera takiruamai i ngā tirohanga e toru: te tātaritanga hanganga matua, te arorau hoahoa, me ngā hononga mahi, e whakarato ana i tētahi tohutoro ngaio mō te kōwhiringa, te tono, me te tiaki.

I. Tātari Hanganga Matua o te Mekameka Roera Rua-Pikitia

Ko te "piko rua" o te mekameka roera piko rua e pā ana ki te tawhiti pokapū hononga mekameka (te tawhiti mai i te pokapū o te pine ki te pokapū o te pine tata) e rua te tawhiti atu i te mekameka roera tikanga. Nā tēnei rerekētanga hoahoa taketake ka hua ake te hoahoa ahurei o ngā wāhanga hanganga matua e whā e whai ake nei, e whai wāhi tahi ana ki ōna painga mahi.

1. Ngā Hononga Mekameka: He Wāhanga Puku "Pihi Roa Ake + Huinga Māmā"
Hoahoa Whakatō: Mā te whakamahi i te whakatō e rua te teitei o te mekameka roera paerewa (hei tauira, ko te whakatō mekameka paerewa o te 12.7mm e rite ana ki te whakatō mekameka whakatō rua o te 25.4mm). Ka whakaitihia te tapeke o ngā hononga mekameka mō te roa tuku ōrite, ka whakaitihia te taumaha mekameka me te uaua o te tāutanga.
Huihuinga: Ko te waeine taraiwa kotahi he "pereti hono o waho e rua + pereti hono o roto e rua + huinga pū roera kotahi," kaua ki te "huinga pereti hono kotahi mō ia nekehanga" e rite ana ki ngā mekameka tuku iho. Mā tēnei ka māmā ake te tatau o ngā wāhanga me te whakapai ake i te pumau o te kawenga mō ia nekehanga.

2. Ngā Rōra me ngā Pūhi: He "Whakaurunga Tino Tika" mō te Whakaiti i te Tōia
Rauemi Rōra: He mea hanga te nuinga ki te maitai waro-iti (hei tauira, te maitai 10#) ka tukuna ki te maimoatanga waro me te tinei, ka tutuki ai te pakeke o te mata o te HRC58-62 hei whakarite i te ātete ki te kakahu ina honoa ki te sprocket. Ka taea te whakamahi i te maitai kore waikura, i ngā kirihou hangarau rānei hei ātete ki te waikura i roto i ētahi tono taumaha. Hoahoa Ringaringa: He urunga ātea te ringaringa me te rōra (0.01-0.03mm), ko te kōhao o roto me te pine he urunga pokanoa. Ka hangaia he hanganga whakaiti-tō e toru-paparanga: "te whakapiringa pine + te hurihanga ringaringa + te hurihanga rōra." Ka whakaitihia e tēnei te tauwehenga waku tuku ki te 0.02-0.05, he iti ake i te waku reti.

3. Pereti Mekameka: "Whānui Whānui + Rauemi Matotoru" hei Tautoko Kume
Hoahoa o Waho: E whakamahia ana e ngā pereti hononga o waho me roto he hanganga "tapawhā whānui", he 15%-20% te whānui ake i ngā mekameka tuku iho o te whakatakotoranga kotahi. Ka marara te pēhanga radial i te wā e mau ana te sprocket, ā, ka ārai i te pakaru o ngā taha o te pereti mekameka.
Kōwhiringa Matotoru: I runga i te whakatauranga kawenga, ko te matotoru o te pereti mekameka he 3-8mm te nuinga (ki te whakaritea ki te 2-5mm mō ngā mekameka tuku iho). He mea hanga ki te maitai waro kaha-teitei (pērā i te 40MnB) mā te tinei me te whakamahana, ka tutuki i ngā pereti mekameka te kaha kume o te 800-1200 MPa, e tutuki ai ngā whakaritenga kawenga kume o ngā tuku roa-roa.

4. Pine: Te Kī ki te Hononga "Diameter Angiangi + Wāhanga Roa"
Hoahoa Diameter: Nā te roa o te piko, he iti ake te diameter o te pine i tō te mekameka paerewa o taua whakatakotoranga (hei tauira, ko te diameter o te pine mekameka paerewa he 7.94mm, ko te diameter o te pine mekameka piko-rua he 6.35mm). Heoi, kua takirua te roa, kia mau ai te hononga i waenga i ngā hononga tata ahakoa he nui ake ngā whānui.
Te Maimoatanga Mata: He mea whakakikorua ki te kōromi, ki te phosphate rānei te mata o te pine, ā, he 5-10μm te matotoru. Ka whakarei ake tēnei paninga i te ātete ki te waikura, ka whakaiti hoki i te waku reti ki te pū o roto o te ringaringa, ka roa ake te ora o te ngenge (e 1000-2000 hāora te roa o te ora o te tuku).

II. Te Hononga Matua i waenga i te Hoahoa Hanganga me te Mahi: He aha i pai ai te mekameka piko-rua mō ngā tuku roa?

Ko ngā āhuatanga hanganga o te mekameka roera rua-piko e kore e whakanui noa i te rahi. Engari, ka aro atu ki te whakaritenga matua o te "tuku roa mai i waenganui ki waenganui" me te whakatutuki i ngā whāinga mahi matua e toru o te "whakaiti i te taumaha, te whakaiti i te tō, me te kawenga pumau." Ko te arorau hononga motuhake koia tēnei:

1. Hoahoa roa → Te taumaha mekameka me ngā utu tāutanga kua whakaitihia
Mō te tawhiti tuku ōrite, he haurua noa iho ngā hononga o te mekameka piko-rua i te mekameka tuku iho. Hei tauira, mō te tawhiti tuku 10-mita, e 787 ngā hononga e hiahiatia ana mō te mekameka tuku iho (piko 12.7mm), ko te mekameka piko-rua ia (piko 25.4mm) e 393 noa iho ngā hononga e hiahiatia ana, ka whakaitihia te taumaha mekameka katoa mā te 40%.

Mā te whakaiti i te taumaha ka whakaiti tika i te "kawenga taupua" o te pūnaha tuku, inā koa i roto i ngā āhuatanga tuku poutū, piko rānei (pērā i ngā ararewa). Ka whakaitihia te kawenga mōtini me te whakaiti i te whakapaunga pūngao (he penapena pūngao i inehia o te 8%-12%).

2. Ngā Pereti Mekameka Whānui + Ngā Pine Kaha-Teitei → Te Pūmautanga o te Whānuitanga Whakapai Ake
I roto i ngā tuku roa (hei tauira, ko ngā tawhiti pokapū neke atu i te 5 mita), ka ngawari ngā mekameka ki te piko nā tō rātou ake taumaha. Mā ngā pereti mekameka whānui ka whakanui ake i te horahanga hononga ki te sprocket (30% te nui ake i ngā mekameka tuku iho), ka whakaiti i te oma i te wā e hono ana (ka whakahaerehia te oma ki roto i te 0.5mm).
Mā ngā pine roa, me te taunga pokanoa, ka ārai i te wetekina o ngā hononga mekameka i te wā e tukuna ana ngā whakawhiti tere-tiketike (≤300 rpm), kia tika ai te tuku (hapa tuku ≤0.1mm/mita).

3. Hanganga Whakaiti Tōia-Papa-Toru → He pai mō ngā Tere Poto me te Ora Roa
Ko ngā mekameka piko-rua te nuinga o te wā e whakamahia ana i roto i ngā tuku tere-iti (ko te tikanga he ≤300 rpm, ki te whakaritea ki te 1000 rpm mō ngā mekameka tikanga). Ko te hanganga poro-poro-toru-paparanga e tohatoha pai ana i te waku pumau i ngā tere iti, e ārai ana i te pakaru wawe o ngā wāhanga. E whakaatu ana ngā raraunga whakamātautau parae i roto i ngā mīhini ahuwhenua (pēnei i te mekameka kawe o te mīhini hauhake whakakotahi), ka taea e ngā mekameka piko-rua te whai oranga ratonga 1.5-2 ngā wā i ngā mekameka tikanga, e whakaiti ana i te auau tiaki.

III. Ngā Āhuatanga Hanganga Whānui: Te Kōwhiri me te Tiaki i ngā Kaupapa Matua mō ngā Mekameka Roera Rua-Pihi

I runga i ngā āhuatanga hanganga o runga ake nei, me whiriwhiri me te tiaki i ngā tono tūturu kia nui ake ai ngā painga o te mahi.

1. Kōwhiringa: Te Whakataurite i ngā Tawhā Hanganga i runga i te "Tawhiti Pokapū Tuku + Momo Utaina"
Mō ngā tawhiti pokapū neke atu i te 5 mita, he pai ake ngā mekameka piko-rua hei karo i ngā raruraru tāutanga uaua me te totohu e pā ana ki ngā mekameka tuku iho nā te nui rawa o ngā hononga.

Mō te kawe kawenga māmā (ngā kawenga iti iho i te 500N), ka taea te whakamahi i ngā pereti mekameka angiangi (3-4mm) me ngā roera kirihou hei whakaiti i ngā utu. Mō te tuku kawenga taumaha (ngā kawenga nui atu i te 1000N), e taunakihia ana kia whakamahia ngā pereti mekameka matotoru (6-8mm) me ngā roera warowaihā hei whakarite i te kaha kume.

2. Tiaki: Arotahi ki ngā "Wāhi Waku + Takahitanga" hei Whakaroa i te Ora.
Te Whakahinuhinu Auau: I ia 50 hāora e mahi ana, werohia he hinu konukōreiti (Momo 2#) ki roto i te āputa i waenganui i te roera me te pūkaha hei ārai i te pakaru o te pūkaha i puta mai i te waku maroke.
Tirotiro Kukū: Nā te mea he ngāwari te roa o ngā piko roa, whakatikatikahia te kukū i ia 100 hāora o te whakamahinga kia noho te totohu o te mekameka i roto i te 1% o te tawhiti pokapū (hei tauira, mō te tawhiti pokapū 10-mita, totohu ≤ 100mm) kia kore ai e motu te hononga mai i te porotiti.

Whakatau: Ko te Hanganga te Kaiwhakatau i te Uara. Ko te "Painga Whānui-Roa" o ngā Mekameka Roera Rua-Piki i ahu mai i te Hoahoa Tika.
Ko ngā āhuatanga hanganga o ngā mekameka roera takirua-rua e aro tika ana ki te hiahia mō te "tuku tawhiti-pokapū-roa" - te whakaiti i te taumaha mate mā te piko roa, te whakapai ake i te pumau mā roto i ngā pereti hononga whānui me ngā pine kaha-teitei, me te whakaroa i te ora mā roto i te hanganga whakaiti-tō e toru-paparanga. Ahakoa he kawe tawhiti o ngā mīhini ahuwhenua, he tuku tere-iti rānei o ngā taputapu keri, ko te ōritetanga hohonu o tōna hoahoa hanganga me te mahi ka waiho hei wāhanga tuku kore e taea te whakakapi i roto i te mara ahumahi.
