Chevron canja wurin: karfi da kuma kasawan

Wannan sashe na makanikai kamar inji sassa, duk dalibai na fasaha fannoni. Jerin ayyukan da ake accented a kan giya, wadda ta zo a cikin da dama siffofin. Hari, helical da herringbone kaya - suna amfani da kusan dukkan masana'antu.

Menene gearing

Kafin mu yi magana game da abin da wani cylindrical herringbone kaya, shi wajibi ne don magance tare da general guzuri. Gearing amfani a aika da Rotary motsi tsakanin shafts. Tun kai tsaye lamba hada da wani biyu daga giya da kaya hakora. Gear rabo canje-canje dangane da kaya size da kuma yawan hakora a kanta.

Canza kusurwa gudu da kuma karfin juyi - ainihin ayyuka na wani kaya, ciki har da herringbone. Broad wannan aikace-aikace daban-daban a masana'antu bukatar ci gaba da ci gaba da kuma kyautata na fasaha halaye na watsa. A sakamakon haka, akwai sabon iri na links, amfani high-ƙarfi gami, hakora, da dai sauransu

Herringbone giya da duk game da su

Kamar yadda muka fahimta, irin wannan alkawari tana nufin wani kaya. Mun ayyana tsarin fasali na wani bit da wani ba watsa. Daga gargajiya kaya da muke da gagarumin bambanci. Da fari dai, da kambi na hakori ne directed a daban-daban kwatance. Haka kuma, a gefe daya na zobe suna karkata a daya shugabanci da baya - a daya gefen.

Yana da hadari a ce da canja wurin da zance da wata babbar yawan abũbuwan amfãni. Alal misali, babu axial load a kan hali, wanda zai iya tsawanta da sabis kumburi. Bugu da kari, irin wannan watsa iya muhimmanci ƙara da kwana na son da hakora, wanda shi ne kamar 25-40 digiri. Duk da yake a cikin al'ada helical giya da iyaka ne 18 digiri.

Hakika, akwai nuances. Da fari dai, babban mawuyaci da babban kudin samar da zance. Tun da irin wannan gearing amfani a aika da babban iko da kuma gudun a cikin rashi na axial lodi, da masana'antu daidaito dole ne sosai high, ya kuma inganta kudin na wannan ƙafafun an samu high. Na biyu, da bukatar yin amfani da iyo shaft zane. Domin wannan sauki dalilin, injiniyoyi ƙoƙarin yin amfani da helical kaya, inda zai yiwu, sa'an nan kuma amfani da zance.

Abũbuwan amfãni zance ƙafafun

Ya kamata a lura cewa duk inji watsa da na kowa amfani ko rashin amfani. Wannan kuma ya shafi Chevron alkawari. Ka yi la'akari da karfi. Da fari dai, high smoothness, wanda aka samu saboda da manyan kwana na hakora. Saboda haka, da girma zai zama yawa fiye da karami da helical kaya. Wannan damar mahara abubuwa don rage nauyi da kuma size na naúra matsayin dukan.

Karko batun amfani na al'ada (na yau da kullum lubrication, culling, babu zafi fiye da kima da kuma inji lalacewar) ne game da 40 000 hours. Haka kuma, da AMINCI na kumburi zai zama sosai high. Yana yana lalacewa ta hanyar rashi na axial lodi a kan hali. Kamar yadda wani sakamako, to, bãbu zafi fiye da kima na shaft da bearings.

A high dace (97-98%) - Wani karfi maki zance ƙafafun. Wannan nuna alama ne sau da yawa kayyade factor a zabi nau'in watsa a cikin wani da aka ba kumburi, kamar yadda shi damar cimma m hasarori a lokacin aiki. Constant kaya rabo ne kuma wani muhimmin factor, wanda ko ba ya mika ga fore, amma har yanzu yana da wani wuri. Irin girma herringbone kaya taka muhimmiyar rawa a cikin aiki da nauyi da wajibi manyan motoci a nodes.

A bit game da shortcomings

Kamar wani irin watsa, wannan yana da dama rashin amfani. Na farko, kamar yadda muka gani a sama, haduwar yi. Kudin zance dabaran ne high isa, ko da yake shi ne m. Sau da yawa a samar a hali na gazawar da wani kumburi yana da muhimmanci don maye gurbin shi da zaran yiwu. A wannan yanayin, daidai dace helical da hari giya, wadda ne sauki tsirar. Amma ga zance, to, a can ne ba haka ba sauki. hawa daidaito dole ne ya kasance m, haka ne kara adadin lokaci ciyar a kan shigarwa part.

Surutu a lokacin aiki - ko wannan shi ne don haka da muhimmanci?

Wani drawback - amo a high gudu. Ko da yake sanyã shi kawai ga zance canja zai zama wauta, saboda shi shafi dukan sashe. A biyu daga karfe hakora meshing a high gudun - shi ke ko da yaushe ringing amo, wanda, ko da yake mur da musamman man shafawa da kuma casings, amma ba gaba daya. An kuma aka ce game da iyo shaft, abin da ake bukata domin daidai aiki na kumburi, da kuma wannan qara wuya daga cikin zane. Yin herringbone kaya ne a hankali sarrafawa a duk matakai, saboda haka, m kayayyakin ne kananan, ko da yake 'yan shekaru da suka wuce da halin da ake ciki ya fi bakin ciki.

A hakori profile

Kamar yadda a duk hakora, musamman da zance irin na hakori iya aiki. Pre-lissafi aka yi herringbone kaya. Wadannan iri hakora:

• dunƙule a daya shugabanci.
• Dunƙule a daban-daban kwatance.
• involute.
• neevolventnye.

Applicability na wani irin kai tsaye dogara a kan abin da yake wajibi a cimma a lokacin taron aiki. Alal misali, idan kumburi da aka tsara tare da yiwuwar kawar da na cibiyar profile aka yi amfani da involute hakori. Bugu da kari, akwai uku zabin da kaya dabaran tsari: haduwa, kuma telescoped al'ada. By canza nesa da cibiyar da profile, wanda zai iya cimma daya ko wani wuri, wanda wajibi ne ga inganta smoothness, kara da bugun jini gudu, da dai sauransu

Shi ne kuma mayar da hankali ne a kan gaskiyar cewa ba daidai ba irin hakori dace a wani batu da zai kai ga irin wannan sakamakon a matsayin: rage hanya kumburi, ta ƙara amo, qazanta zafi fiye da kima, da dai sauransu Saboda haka, mafi muhimmanci mataki ne kawai a msar tambayar lissafi na watsa.

Rarraba zance ƙafafun

Kamar yadda muka gani a sama, da inji watsa ana amfani da mutane da yawa masana'antu. Bayan dauke da zance canja wuri, amfani ko rashin amfani da wanda ya nuna su amfani, za a iya ce game da bambancinsa. Duk da haka gudanar a aiki a ko'ina cikin chevrons ba za a dauke dace saboda da high kudin da kuma zane mai cika.

Amma duk da wannan, su ne ba makawa a metallurgical Enterprises. Akwai herringbone kaya a yi amfani da mirgina Mills, yankan inji da kuma sauran kayan aiki. Wannan shi ne saboda cewa da zance dabaran iya zama:

• low-gudun;
• matsakaici gudun;
• gudun;
• rundunar motoci.

Ayuba irin dogara da gefe gudu. Da aka fi amfani canja wurin zance a high gefe gudu (30 m / s). Automotive - wani masana'antu, wanda ba tare da yin amfani da inji watsa wuya a sarrafa. Haka ya shafi da sinadaran da abinci masana'antu.

Material

Kusan duk da giya ne batun tsanani lalacewa. Saboda wannan dalili ya zama dole don amfani high-ƙarfi gami, wanda dole mu jimre wa da aikin a wuya yanayi. Nan da nan zance ko kaya dabaran yi na karfe, amma ya kamata zai fi dacewa kasance hakora tagulla. Amma idan ka yi amfani da tagulla a cikin tsarki tsari, shi ne ma tsada. Domin wannan sauki dalilin, da hakora narke gami karfe tare da tagulla shafi.

Yana yakan faru da cewa site ne batun bai kai ba lalacewa. Wannan ya faru domin dalilai daban-daban:

• runout a watsa;
• zafi fiye da kima na ƙafafun da pinions.
• kasa lubrication.

A mafi yawan wadannan lokuta, shi ba ya canja zuwa wani sabon da kuma gyara ta fusing hakora. Wannan hanya da ake amfani a kusan duk inji watsa, idan zai yiwu, kuma dace.

don takaita

Babban amfani da herringbone kaya da yake a cikin yiwuwar ta yin amfani da a babban gudu. A muhimmanci irin rawa da gaskiyar cewa babu wani axial load a kan hali. Haka kuma, zafi fiye da kima ne cire kumburi, wanda shi ne mafi kowa hanyar da mafi yawan 'yan gazawar.

A lokaci guda, babban kudin Manufacturing zance ƙafafun da giya ba su yarda da kumburi a ko'ina. Haka ya shafi lokacin da shigarwa na herringbone kaya, kazalika da m kwararru alhakin da kafuwa da kuma commissioning na naúra aiki.
