Nā Bearings Roller Crossed Miniature

 

Liʻiliʻinā bearings wili i keʻahoʻohana nui ʻia i nā turntables mīkini hana, nā mea lapaʻau, nā lima robotic, a me nā ʻāpana wili o nā mea ʻike ma muli o ko lākou liʻiliʻi, kūpaʻa hana maikaʻi, pololei wili kiʻekiʻe, a me ke kūpaʻa kiʻekiʻe. Hōʻike ʻia kēia mau ʻāpana mechanical e nā hana hoʻomaka-hoʻōki pinepine; no laila, he mea nui loa ke aʻo ʻana i nā ʻano torque frictional o nā bearings wili kea miniature.

 

ʻAno o ka MiniatureNā Bearings Roller i keʻa ʻia

ʻO nā bearings wili liʻiliʻi i keʻa ʻia he ʻelua hapalua apo waho like, kahi apo o loko, nā wili, a me kahi pā hoʻohui. Hoʻopili ʻia nā hapalua apo o waho ʻelua e nā wili, a ua hoʻokaʻawale ʻia nā wili e nā ʻeke pā. Ma muli o ka hoʻonohonoho ʻana o nā wili e pili ana i kahi ʻano keʻa, hiki i nā bearings wili liʻiliʻi ke kū i nā ukana axial, nā ukana radial, a me nā manawa hoʻohuli. I ka wā o ka hana, ua paʻa ke apo o waho, a ke wili nei ke apo o loko.

 

Nā ʻano Torque Frictional o MiniatureNā Bearings Roller i keʻa ʻia

 

1) ʻO ka torque frictional o ka miniaturenā bearings wili i keʻapiʻi me ka hoʻonui ʻana i ka wikiwiki o ka wili a me ka manawa hoʻohuli. I nā noi turntable i hoʻokau ʻia i nā manawa hoʻohuli, pono e hoʻonohonoho pono ʻia nā kūlana hana e hōʻemi i ka pilikia o ka hoʻonui ʻia ʻana o ka torque frictional bearing.

 

2) No ka ʻae radial like, ʻo ka manawa hoʻohuli nui aʻe e hopena i ka torque frictional bearing nui aʻe. I ka piʻi ʻana o ka ʻae radial, e emi ana ka torque frictional bearing, akā paʻa ia i ka wā e ʻoi aku ai ka ʻae radial ma mua o 5 μm. Ke noʻonoʻo nei i ke kūpaʻa hana, ua ʻōlelo ʻia e kāohi i ka ʻae radial ma waena o 5 a me 10 μm.

 

3) ʻO ka nui o ka waiwai paʻa o ka ʻokoʻa kihi raceway, ʻoi aku ka ʻike ʻia o ka hopena ukana ma waho o ke kikowaena ma ke kuhikuhi roller generatrix, e alakaʻi ana i kahi hoʻolaha kaomi ʻoi aku ka like ʻole a me ka torque frictional bearing nui aʻe. Manaʻo ʻia e kāohi i ka ʻokoʻa kihi raceway o loko i loko o ± 2′ a me ka ʻokoʻa kihi raceway o waho i loko o ± 1′ e hōʻemi i ka torque frictional bearing.

 

4) Hāʻawi nā wili i hoʻololi ʻia i ka Logarithmically i ka torque frictional haʻahaʻa ma luna o kahi ākea ākea o nā manawa hoʻohuli. Eia nō naʻe, i ka wā e hoʻokokoke aku ai ka manawa hoʻohuli i 400 N·m, ʻaʻole koʻikoʻi ka ʻokoʻa o ka pono ma waena o nā wili i hoʻopuni ʻia a me nā wili i hoʻololi ʻia i ka logarithmically i ka hōʻemi ʻana i ka torque frictional bearing. No ka hōʻemi ʻana i ka torque frictional, ua ʻōlelo ʻia nā wili i hoʻololi ʻia i ka logarithmically i ka hoʻolālā bearing.

 

5) Ka mana o nā palena hoʻonohonoho onā bearings wili i keʻaMa ke ʻano o ka torque frictional, mai ka nui loa a i ka liʻiliʻi loa, penei: ka radial clearance, ka oki ʻana o ke kihi raceway o loko, ka oki ʻana o ke kihi raceway apo o waho o luna, a me ka oki ʻana o ke kihi raceway apo o waho o lalo. No laila, pono e hoʻomalu mua ʻia ka radial clearance o nā bearings roller i keʻa ʻia, a ukali ʻia e ka oki ʻana o ke kihi raceway, ʻoiai ka oki ʻana o ke kihi raceway o loko, e hoʻomaikaʻi i ka hana torque frictional o ka bearing.
