Yintoni i-bearing preload? Injongo yayo?

 

UkuthwalaUkulayisha kwangaphambili ngamandla asetyenziswa kwi-bearing ngokulungiswa kwe-axial ngokumalunga nelinye i-bearing ngaphambi kokuba kusetyenziswe umthwalo "wokusetyenziswa" (umthwalo wangaphandle), okanye ngokwenziwa "kwe-negative clearance" (ukulayisha kwangaphambili kwangaphakathi) phakathi kweendlela zomdyarho kunye nezinto eziqengqelekayo kwi-bearing.

 

Iinjongo eziphambili zokuthwala ukulayisha kwangaphambili zezi zilandelayo:

 

1. Phucula ukuchaneka kwesikhokelo sebheri. Ukuchaneka kwesikhokelo seshafti Ishafti exhaswa yibheri yokulayisha kwangaphambili inobuchaneka obuphezulu bokuqondisa, kuba amandla okugoba eshafti phantsi komthwalo anqunyelwe kukulayisha kwangaphambili. Iibheringi zokwahluka kwesafti zokulayisha kwangaphambili zinobuchaneka obuphezulu bokuqondisa kunye nokuqina okuphezulu, okugcina i-meshing echanekileyo nengaguqukiyo, kwaye amandla ongezelelweyo anamandla aphantsi, okubangela ingxolo ephantsi yokusebenza kunye nobomi benkonzo ende yeegiya ze-meshing.

 

2. Phucula ubulukhuni. Ukuqina kwebheri kuchazwa njengomlinganiselo wamandla asetyenziswa kwibheri ukuya kubungakanani bokuguquguquka kwe-elastic kwebheri. Kuluhlu oluthile lomthwalo, ukuguqulwa kwe-elastic kwebheri elayishiweyo kuncinci kunokwebheri engakhange ilayishwe.

 

3. Ukusebenza kwengxolo ephantsi. Okukhona indawo yokubaleka kwebheri incinci, kokukhona isikhokelo sezinto eziqengqelekayo kwindawo engenamthwalo, kwaye kokukhona ibheri ingabi ngxolo ingako xa isebenza.

 

4. Imbuyekezo yokuguguleka kunye nesinki. Ngexesha lokusebenza, ukuguguleka kunye nokuhlaliswa kwebheringi kwandisa indawo evulekileyo, kodwa oku kunokubuyiselwa ngokulayisha kwangaphambili. Ihlawulela ukuguguleka kunye nokuhlaliswa kokusebenza, kunye nobomi obude bokusebenza.

Yandisa ubomi bokusebenza. Kwezinye iimeko, ulungiselelo lokudibanisa nomthwalo wangaphambi kokulayisha lunokuphucula ukuthembeka kokusebenza kwaye lwandise ubomi benkonzo. Ngenxa yokuba ubungakanani obufanelekileyo bomthwalo wangaphambi kokulayisha buphucula ukusasazwa komthwalo webhereyi, inokwandisa ubomi bayo bokusebenza.
