II. Babban Dabaru: Ka'idar "Daidaita Juna" ta Sauti da Sauri
Aikin masana'antu mai faɗi ya tabbatar da cewa sautin sarkar na'ura mai juyawa da saurin suna da alaƙa bayyananniyar "daidaituwa" - wato, mafi girman saurin, ƙaramin sautin yakamata ya kasance, yayin da ƙarancin saurin, mafi girman sautin zai iya zama. Ma'anar wannan ka'ida ita ce daidaita "buƙatun kaya" da "haɗarin damuwa mai ƙarfi." Ana iya raba wannan zuwa girma uku:
1. Aiki mai sauri (yawanci n > 1500 r/min): Ƙaramin bugun kira yana da mahimmanci.
Idan saurin sprocket na tuƙi ya wuce 1500 r/min (kamar a cikin fanka da ƙananan drives na mota), matsin lamba mai ƙarfi da ƙarfin centrifugal akan sarkar suna ƙaruwa sosai. Amfani da babban sarkar a cikin wannan yanayin na iya haifar da matsaloli biyu masu mahimmanci:
Yawan nauyin da ke kan haƙoran ...

Bayan fahimtar ka'idar, lokaci ya yi da za a aiwatar da ita ta hanyar hanyoyin da aka tsara. Matakai 4 masu zuwa za su taimaka muku da sauri zaɓar sarkar da ta dace da kuma guje wa kurakurai da suka taso sakamakon dogaro da gogewa:
Mataki na 1: Gano Ma'aunin Muhimmanci - Tattara Bayanai 3 Da Farko
Kafin zaɓar sarkar, dole ne ku sami waɗannan mahimman sigogi guda uku na kayan aikin; babu ɗayansu da za a iya cirewa:
Saurin sprocket na tuƙi (n): Sami wannan kai tsaye daga littafin jagorar ƙarshen tuƙi ko na injin. Idan saurin ƙarshen tuƙi ne kawai yake samuwa, yi lissafin baya ta amfani da dabarar "Rabo na watsawa = adadin haƙoran da ke kan sprocket na tuƙi / adadin haƙoran da ke kan sprocket ɗin tuƙi."
Ƙarfin canja wuri mai ƙima (P): Wannan ita ce ƙarfin (a cikin kW) da kayan aiki ke buƙata don canja wurinsa yayin aiki na yau da kullun. Wannan ya haɗa da nauyin da ya kai kololuwa (kamar nauyin girgiza yayin farawa, wanda yawanci ana ƙididdige shi sau 1.2-1.5 na ƙarfin da aka ƙididdige).

Mataki na 3: Tabbatar da Sauti ya cika ƙarfin Lodawa ta amfani da Wutar Lantarki
Bayan zaɓin sautin farko, tabbatar da cewa sarkar za ta iya jure wa ƙarfin da aka ƙima ta amfani da "Tsarin Lissafin Wuta" don guje wa gazawar wuce gona da iri. Idan aka ɗauki misalin sarkar naɗin ISO na yau da kullun, dabarar da aka sauƙaƙe kamar haka:
Watsa wutar lantarki da aka yarda da ita ta sarka (P₀) = K₁ × K₂ × Pₙ
Inda: K₁ shine ma'aunin gyaran gudu (sauri mafi girma yana haifar da ƙarancin K₁, wanda za'a iya samu a cikin kundin sarkar); K₂ shine ma'aunin gyaran yanayin aiki (0.7-0.9 don yanayi mai wahala, 1.0-1.2 don muhalli mai tsabta); kuma Pₙ shine ƙarfin da sarkar ta kimanta (wanda za'a iya samu ta hanyar jimla a cikin kundin masana'anta).
Sharaɗin tabbatarwa: Dole ne P₀ ya cika ≥ 1.2 × P (1.2 shine abin da ke tabbatar da aminci, wanda za'a iya ƙara shi zuwa 1.5 ga yanayin aiki mai nauyi).
Mataki na 4: Daidaita tsarin ƙarshe bisa ga sararin shigarwa.
Idan aka ƙayyade girman da aka zaɓa da farko ta hanyar sararin shigarwa (misali, sararin cikin kayan aikin ya yi ƙanƙanta sosai don ɗaukar babban sarkar silinda), za a iya yin gyare-gyare guda biyu:
Rage girman + ƙara yawan layukan sarka: Misali, idan da farko ka zaɓi layi ɗaya na girman 25.4mm (#100), za ka iya canzawa zuwa layuka biyu na girman 19.05mm (#80-2), wanda ke ba da damar ɗaukar kaya iri ɗaya amma ƙaramin girma.
Inganta adadin haƙoran sprocket: Yayin da ake ci gaba da daidaita sautin, ƙara yawan haƙoran da ke kan sprocket ɗin tuƙi (yawanci zuwa aƙalla haƙora 17) na iya rage girgizar sarka kuma a kaikaice inganta daidaitawa mai sauri.
IV. Kurakurai da Aka Saba Yi Gujewa: Guji Waɗannan Kurakurai 3
Ko da bayan sun ƙware a tsarin zaɓe, mutane da yawa har yanzu suna kasawa saboda rashin kula da cikakkun bayanai. Ga guda uku daga cikin kuskuren da aka fi sani da kuma mafita:
Kuskure na 1: Mayar da hankali kan ƙarfin ɗaukar kaya kawai yayin da ake watsi da daidaita saurin gudu
Kuskure: Ganin cewa "babban bugun yana nufin ƙarfin ɗaukar kaya," an zaɓi babban sarkar bugun don aiki mai sauri (misali, sarkar #120 don injin 1500 rpm).

Kuskure: Amfani da saurin pulley da aka tuƙa a matsayin abin da ake so (misali, idan saurin pulley da aka tuƙa shine 500 rpm kuma ainihin saurin pulley ɗin drive shine 1500 rpm, ana zaɓar babban sautin bisa ga 500 rpm). Sakamako: Matsanancin ƙarfi mai ƙarfi a cikin sarkar, wanda ke haifar da "lalacewar fil" (lalacewa fiye da 0.5mm a cikin wata ɗaya). Magani: Dole ne a yi amfani da "gudun pulley ɗin drive" a matsayin ma'auni. Idan ba a tabbatar ba, a lissafta ta amfani da rabon saurin motar da raguwa (gudun pulley ɗin drive = rabon saurin motar / raguwa).
Kuskure Na 3: Yin watsi da Tasirin Man Shafawa Kan Daidaita Sauri-Pitch
Kuskure: idan aka ɗauka cewa "zaɓar madaidaicin sautin ya isa," a guji shafa man shafawa ko amfani da man shafawa mara kyau a ƙarƙashin yanayi mai sauri.

Magani: Don yanayin saurin gudu (n > 1000 rpm), dole ne a yi amfani da man shafawa mai digo ko man shafawa mai wanka. Dole ne a daidaita danko mai da saurin (mafi girman saurin, haka nan ƙarancin danko).
V. Nazarin Shari'ar Masana'antu: Ingantawa daga Rashin Nasara zuwa Kwanciyar Hankali
Layin jigilar kaya a wani masana'antar kayan mota yana fuskantar karyewar sarka sau ɗaya a wata. Ta hanyar inganta daidaiton saurin gudu, mun tsawaita rayuwar sarkar zuwa shekaru biyu. Cikakkun bayanai sune kamar haka:
