1. Diffiniad Sylfaenol a Nodweddion Strwythurol
Bearings UCP (Bearings Bloc Pillow(gyda Mewnosodiad) yn unedau wedi'u cydosod ymlaen llaw sy'n cynnwys mewnosodiad beryn wedi'i leoli mewn pedestal haearn bwrw neu ddur wedi'i wasgu. Mae'r nodweddion allweddol yn cynnwys:
• Arwyneb Allanol Sfferig: Mae gan ddiamedr allanol y beryn ddyluniad sfferig, sy'n galluogi gallu hunan-alinio ±3°.
• Ffurfweddiad wedi'i Selio ymlaen llaw: Mae morloi rwber safonol (ffurfweddiad RS neu 2RS) yn darparu amddiffyniad gradd IP54 rhag llwch a dŵr yn dod i mewn.
• Tai Safonol: Yn cydymffurfio ag ISO 113:2015, gan sicrhau bod modd cyfnewid bylchau tyllau mowntio rhwng brandiau.
2. Egwyddorion Gweithredu a Phriodweddau Mecanyddol
2.1 Mecanwaith Trosglwyddo Llwyth
Mae trosglwyddo llwyth yn digwydd trwy elfennau rholio (peli dur) rhwng y cylchoedd mewnol ac allanol:
• Llwythi Rheiddiol: Wedi'u trosglwyddo ar hyd radiws y dwyn (sy'n cyfrif am ~70% o gapasiti llwyth).
• Llwythi Echelinol: Yn gallu ymdopi â grymoedd echelinol unffordd (≈20% o gapasiti llwyth rheiddiol).
2.2 Priodweddau Tribolegol
• Cyfernod ffrithiant rholio isel iawn: 0.001–0.003
• Cyflymder uchaf: 3,000 rpm gydag iro saim seiliedig ar lithiwm (oes saim 2,000 awr @ 70°C).
3. Senarios Cymhwysiad Nodweddiadol
3.1 Peiriannau Amaethyddol
• Siafftiau gyrru cynaeafwr cyfun (tymheredd gweithredu: -30°C i 80°C)
• Gostyngwyr gêr llyngyr system ddyfrhau (angen haenau gwrth-cyrydu)
3.2 Diwydiant Prosesu Bwyd
• Unedau gyrru gwregys cludo (amrywiadau dur di-staen sy'n cydymffurfio â'r FDA)
• Mecanweithiau cranc mewn peiriannau pecynnu (sy'n gwrthsefyll llwythi sioc cylchol)
3.3 Offer Mwyngloddio
• Sgriniau dirgrynol mewn peiriannau malu (angen seliau labyrinth atodol)
• Rholeri segur cludwr gwregys (datrysiadau iro arbennig ar gyfer amgylcheddau llwchog)
