He aha ka Cam Bearing? Nā ʻano a me ka mālama ʻana o ke Cam bearing

 

ʻO ke kāmela bearing kekahi ʻano bearing, me kahi apo waho mānoanoa o ka bearing nila roller bearing a me ka hoʻohuihui bolt; Hāʻawi ʻia ka bolt o ka bearing me kahi kahawai ʻaila lubricating; ʻO ka ʻili waho o ke apo waho he cylindrical a spherical, hiki ke koho ʻia e like me ka noi maoli; Hoʻohana ʻia ke ʻano eccentric no nā camshafts automotive (nā shafts e kaohi i ka wehe ʻana a me ka pani ʻana o nā valves i nā mīkini piston) no ka mea he kūpono ia e hoʻoponopono pololei i ke kūlana axis o nā bolts i ka wā e kau ai i nā bearings.

 

Nā hiʻohiʻona o nā bearings cam:

 

1. ʻO ke apo waho mānoanoa o ka nila wili hao a me ka hoʻohuihui ʻana o ka bolt;

 

2. Aia nā moʻo metric a me nā moʻo imperial i ka nui;

 

3. Hoʻonohonoho ʻia kahi kahawai ʻaila lubricating i loko o ka bolt o ka bearing;

 

4. I mea e maʻalahi ai ke kau ʻana, ua hoʻolālā ʻia ka ʻaoʻao nui o ka bearing me ke ʻano hui wrench "hoʻokahi huaʻōlelo" a me ke ʻano "hexagonal hole type";

 

5. ʻO ka ʻili waho o ke apo waho he cylindrical a spherical, hiki ke koho ʻia e like me ka noi maoli;

 

6. ʻO ke ʻano wili piha he kūpono ia no nā hanana e hali ana i nā ukana nui a me nā wikiwiki haʻahaʻa;

 

7. Hiki i ke ʻano eccentric ke hoʻololi maʻalahi a pololei i ke kūlana axis o ka bolt i ka wā e hoʻokomo ai i ka bearing.

 

Ka mālama ʻana i nā bearings cam:

 

1. ʻO ka pamu rotor lobe i hoʻohana hou ʻia e pono e hoʻololi ʻia me ka grease (ʻaila) ma hope o 100 mau hola o ka hana, a laila hoʻololi ʻia i hoʻokahi manawa i kēlā me kēia 500 mau hola o ka hana.

 

2. Ma hope o 1500 mau hola o ka hana, pono e hoʻololi ʻia ka ʻaila, a ʻaʻole pono e nui loa a liʻiliʻi paha ka nui o ka ʻaila, no ka mea, ʻo ka nui a liʻiliʻi paha o ka ʻaila e hoʻomehana ai i ka bearing, a ʻo ka nui o ka ʻaila e pono e kāohi ʻia ma

2/1----2/3 o ka nui o ke keʻena hali.

 

3. No nā bearings i lubricated ʻia me ka ʻaila lubricating, pono e hoʻohui ʻia ka nui o ka ʻaila i ke kūlana i kuhikuhi ʻia.

 

4. Pono e hoʻomaʻemaʻe ʻia a sila ʻia ka ipu me ka ʻaila poni a i ʻole ka ʻaila momona i nā manawa maʻamau, ʻaʻohe lepo, nā ʻōpala hao a me nā mea ʻē aʻe, i ʻole e hōʻino i ka bearing.

 

5. Hana ʻia ka bearing motika i ka nano grease, kahi i hōʻike ʻia e ke kūpaʻa wela kiʻekiʻe (125 °C), akā maʻalahi ka hoʻoheheʻe ʻia i ka wai, no laila ʻaʻole hiki ke hoʻohana ʻia no ka lubrication o nā bearings pamu wai.
