Ukongeza kumacandelo okuthwala ukukhutshwa kwangaphambili, u-Timken uye waqulunqa iindlela ezintlanu ezisetyenziswa ngokuqhelekileyo zokumisela ngokuzenzekelayo ukukhupha imvume (okt SET-RIGHT, ACRO-SET, PROJECTA-SET, TOQUE-SET kunye ne-CLAMP-SET) njengeenketho zoLungiso lwencwadana. Jonga kwiThebhile 1-"Ukuthelekiswa kweendlela ze-tapered roller bearing set clearance" ukubonisa iimpawu ezahlukeneyo zezi ndlela kwifomathi yetafile. Umqolo wokuqala wale theyibhile uthelekisa ukukwazi kwendlela nganye yokulawula ngokufanelekileyo "uluhlu" lokuthwala ukukhutshwa kofakelo. Ezi xabiso zisetyenziselwa kuphela ukubonisa iimpawu ezipheleleyo zendlela nganye ekusekweni ukukhutshwa, kungakhathaliseki ukuba imvume isetelwe "ukulayishwa kwangaphambili" okanye "i-axial clearance". Ngokomzekelo, phantsi kwekholamu ye-SET-RIGHT, ulindelo (ixesha eliphezulu elinokwenzeka okanye i-6σ) utshintsho lwemvume, ngenxa yokulawula ukunyamezela okuthe ngqo kunye nezindlu / ukunyamezela kwe-shaft, kunokusuka kumncinci oqhelekileyo we-0.008 intshi ukuya kwi-0.014 intshi. Uluhlu lokucoca lunokwahlulwa phakathi kwe-axial clearance kunye nokulayishwa kwangaphambili ukwenzela ukwandisa ukusebenza kwe-bearing / application. Jonga kwi-Figure 5-"Isicelo seNdlela yokuSebenza ngokuSebenzayo yokuSeta ukuQinisekisa ukuBeka". Eli nani lisebenzisa uyilo oluqhelekileyo lwetrektara yezolimo oluqhutywa ngamavili amane njengomzekelo ukubonisa ukusetyenziswa ngokubanzi kwendlela yokucoca iibheringi eziqengqelekayo.
Siza kuxoxa ngokweenkcukacha ngeenkcazo ezithile, ithiyori kunye neenkqubo ezisesikweni zokusetyenziswa kwendlela nganye kwezi zahluko zilandelayo zale modyuli. Indlela ye-SET-RIGHT ifumana imvume efunekayo ngokulawula ukunyamezela kokunyamezela kunye nenkqubo yokufakela, ngaphandle kwesidingo sokulungelelanisa ngesandla i-TIMKEN tapered roller bear. Sisebenzisa imithetho enokwenzeka kunye neenkcukacha-manani ukuqikelela isiphumo soku kunyamezelana ekuthwaleni imvume. Ngokubanzi, indlela ye-SET-RIGHT idinga ukulawulwa okungqongqo kokunyamezela kwe-machining ye-shaft / i-bearing house, ngelixa ulawula ngokungqongqo (ngoncedo lwamabanga achanekileyo kunye neekhowudi) ukunyamezela okubalulekileyo kweebheringi. Le ndlela ikholelwa ukuba icandelo ngalinye kwindibano linokunyamezelana okubalulekileyo kwaye kufuneka lilawulwe kuluhlu oluthile. Umthetho wamathuba ubonisa ukuba amathuba okuba icandelo ngalinye kwindibano liyinyameko encinci okanye indibaniselwano yokunyamezelana okukhulu kuncinci kakhulu. Kwaye ulandele "ulwabiwo oluqhelekileyo lonyamezelo" (Umfanekiso 6), ngokwemigaqo yezibalo, i-superposition yazo zonke iinxalenye zobukhulu zivame ukuwela phakathi koluhlu olunokwenzeka lokunyamezela. Injongo yendlela ye-SET-RIGHT kukulawula kuphela ukunyamezela okubalulekileyo okuchaphazela ukuthwala imvume. Olu kunyamezelana lunokuba lungaphakathi ngokupheleleyo kwibheringi, okanye lusenokubandakanya amacandelo athile okufakwa (okt, ububanzi A no-B kuMfanekiso 1 okanye uMzobo 7, kunye nedayamitha yangaphandle yeshafti kunye nedayamitha yokuthwala indlu yangaphakathi). Isiphumo kukuba, ngokusemandleni aphezulu, imvume yokufaka i-bearing awela ngaphakathi kwendlela eyamkelekileyo ye-SET-RIGHT. Umzobo 6.

Akukho luhlengahlengiso lufunekayo xa usebenzisa indlela SET-RIGHT. Ekuphela kwento ekufuneka yenziwe kukudibanisa kunye nokucinezela iindawo zoomatshini.
Yonke imilinganiselo echaphazela ukunyanzeliswa kokukhutshwa kwindibano, njengokuthwala ukunyamezela, i-shaft diameter yangaphandle, ubude be-shaft, ubude bezindlu ezithwele, kunye nezindlu ezithwele i-diameter yangaphakathi, zibhekwa njengezinto ezizimeleyo xa kubalwa uluhlu olunokwenzeka. Kumzekelo kuMzobo we-7, zombini iindandatho zangaphakathi nangaphandle zifakwe kusetyenziswa i-tight fit fit, kwaye i-cap end igxininiswe nje ekupheleni kwe-shaft. s = (1316 x 10-6)1/2= 0.036 mm3s = 3 x 0.036=0.108mm (0.0043 in) 6s = 6 x 0.036= 0.216 mm (0.0085 intshi) 99.73% yoluhlu olunokwenzeka (i-intshi) 99.73% yoluhlu olunokwenzeka 0.654 Kwi-100% ye-mm (0.0257 intshi) indibano (umzekelo), khetha i-0.108 mm (0.0043 intshi) njengemvume ephakathi. Kwi-99.73% yendibano, uluhlu olunokwenzeka lokukhutshwa luyi-zero ukuya kwi-0.216 mm (0.0085 intshi). † Amakhonkco amabini angaphakathi azimeleyo ahambelana ne-axial variable, ngoko ke i-axial coefficient iphindwe kabini. Emva kokubala uluhlu olunokwenzeka, ubude begama le-axial dimension kufuneka buzimisele ukufumana imvume yokuthwala efunekayo. Kulo mzekelo, yonke imilinganiselo ngaphandle kobude be-shaft iyaziwa. Makhe sijonge indlela yokubala ubude begama le-shaft ukufumana imvume yokuthwala efanelekileyo. Ukubalwa kobude be-shaft (ukubalwa kwemilinganiselo yegama): B = A + 2C + 2D + 2E + F [2apho: A = ububanzi obuphakathi kwendlu phakathi kwamakhonkco angaphandle = 13.000 mm (0.5118 intshi) B = umyinge we-shaft Ubude (TBD) C = Umyinge wokuthwala ububanzi phambi kofakelo = 21.550 mm (0.8484 intshi) D = Ukwandisa ububanzi bokuthwala ngenxa ye-avareji yangaphakathi yeringi efanelekileyo * = 0.050 mm (0.0020 intshi) E = Ukunyuka kobubanzi obuthwele ngenxa umyinge wangaphandle umsesane ukulingana * = 0.076 mm (0.0030 intshi) F = (efunekayo) umyinge wokukhutshwa kwe-avareji = 0.108 mm (0.0043 intshi) * Iguqulelwe kwi-axial unyamezelo olulinganayo.
