Ua koho ʻia ke ʻano alakaʻi e like me ke ʻano o ka hale paʻahao

Alakaʻi ʻia ka pā paʻi e kahi mea ʻōwili

He māmā ke kaumaha o ka hale paʻi, waena ka ikaika, liʻiliʻi ka manawa o ka inertia, a maʻalahi hoʻi e hoʻokele a alakaʻi. Eia kekahi, he liʻiliʻi ka nui o ka ʻāpana ʻāpana o ka hale paʻi, hiki ke hoʻomaʻemaʻe i ke alanui ʻaila lubricating; I ka wā e lubrication aila ...hāpai ʻanaa he wahi mālama momona nui aʻe, kahi mea e kūpono ai i ka hōʻoia a me ka hoʻolōʻihi ʻana i ke kaʻina hana mālama ʻole a i ʻole ke ola paʻa o ka bearing. Eia nō naʻe, he palupalu ka paʻakikī o ka hale paʻi a ʻaʻole ia e kū i ke komo ʻana ma lalo o nā kūlana e like me ka wikiwiki kiʻekiʻe, ka wikiwiki a me ka deceleration, a me ka hoʻololi kuhikuhi. Hoʻohana nui ʻia ka hale paʻi no nā mea liʻiliʻi a me nā mea liʻiliʻi.nā mea e hāpai anaa ma lalo, ke alakaʻi ʻana i nā mea ʻōwili; Aia kekahi mau ʻano bearings i alakaʻi ʻia e nā ferrules, e like me ka hale paʻa M-type o nā bearings roller cylindrical ma ke ʻano he alakaʻi apo waho.

 

Alakaʻi ʻia nā pā palaki paʻa a me nā ʻenekinia e nā ferrules a i ʻole nā ​​​​mea ʻōwili

Hoʻohana pinepine ʻia nā pā paʻa i nā manawa ikaika kiʻekiʻe a me nā bearings nui, hiki ke ʻae i ka wikiwiki hana kiʻekiʻe a me ka mahana hana i hoʻohālikelike ʻia me nā pā i hoʻopaʻa ʻia, a hiki ke kū i nā ukana kaumaha a i ʻole nā ​​​​kaumaha paʻakikī e like me ka haʻalulu, ka haʻalulu, ka hoʻololi kuhikuhi, a me ka ukana loli, akā ma muli o ka nui o ka nui, pono nō hoʻi ka ikaika kauō nui e hoʻokele iā ia; Ma muli o ka ikaika o ka mea, hiki iā ia ke mālama i kahi i loko o ka pā, hoʻemi i ka mamao ma waena o nā ʻeke, hoʻonui i ka helu o nā mea ʻōwili, a hoʻonui i ka hiki ke halihali. Ke lawe nei i ka pā paʻa keleawe i hoʻohana pinepine ʻia ma ke ʻano he laʻana, loaʻa iā ia nā pono o ka ikaika kiʻekiʻe, "pālua friction haʻahaʻa" me ka ferrule kila bearing, ka liʻiliʻi o ka pilikia o ka "pipili", nā ʻano ʻaʻahu maikaʻi, ka liʻiliʻi o ka abrasion, ke kūpaʻa ʻana i ka corrosion, maʻalahi e hōʻoia i ka pololei o ka hana ʻana, a me ka hilinaʻi kiʻekiʻe o ka hoʻohana.

 

Ke hoʻohālikelike ʻia me nā stamping a me nā hale paʻa, he māmā kona (manawa liʻiliʻi o ka inertia, ka loli liʻiliʻi o ka torque), ka ikaika maikaʻi a me ka elasticity (hiki ke hoʻouka ʻia nā mea ʻōwili hou aʻe, hiki ke hoʻihoʻi ʻia i ke kūlana mua ma hope o ka deformation ikaika), ka walaʻau haʻahaʻa (me ka hopena damping haʻalulu), hiki ke hoʻololi i ka wikiwiki o ka laina paheʻe kiʻekiʻe (ʻili laumania, ke kū'ē ʻana i ke komo ʻana a me nā ʻāpana abrasive ʻaʻole e hoʻoulu i ka haumia a me ka hōʻino ʻana i ka grease lubricating e like me nā abrasives hale metala). Loaʻa iā ia nā pono koʻikoʻi e like me ka hana lubrication palena maikaʻi (haʻahaʻa ka friction, piʻi haʻahaʻa ka mahana, ka lubrication ponoʻī) a me ka palekana kiʻekiʻe (ʻoiai inā ua ʻōwili ʻia i loko o kahi flake ma hope o ka fragmentation, hiki iā ia ke hoʻomau i ka hana no ka manawa pōkole me ka ʻole o ka hoʻoulu ʻana i nā pōʻino koke).

 

ʻO nā pā palaki ʻenekinia i hoʻohana pinepine ʻia no ke alakaʻi ʻana i nā ʻāpana wili:

1) Hale PA. He waiwai kūpono ke kumukūʻai o ka hale PA66 a he hana piha maikaʻi loa, akā ʻaʻole maikaʻi kona kūpaʻa i ka mahana a me ke kūpaʻa o ka dimensional, no laila he paʻakikī ke hoʻololi i ke alakaʻi ʻana o nā ferrules me ka friction paheʻe nui. Ma ke ʻano he "mana i hoʻonui ʻia" o ka hale PA66, ʻoi aku ka maikaʻi o ka hana o ka hale PA46 i ke kūpaʻa wela, ke kūpaʻa aila, ke kūpaʻa ʻaʻahu, ke kūpaʻa kolo, ke kūpaʻa luhi, a pēlā aku, a ua hoʻopili maikaʻi ʻia i loko.nā mea e hāpai anae like me nā ʻenekini AC kaʻa, nā pahu pahu, nā compressors air conditioning, a pēlā aku.

 

2) Hale PTFE. Ua kapa ʻia ʻo PTFE ʻo ia ke "mōʻī o nā plastics", nona ka liʻiliʻi loa o ke koina friction (mea lubricating aila ʻole kūpono), ka laulā ākea o ke kūpaʻa mahana (-196 ~ 260 °C), ka hana anti-aging maikaʻi loa, ka liʻiliʻi loa o ka ʻili me ka ʻole o ka hoʻopili ʻana i kekahi mea, a aneane ʻaʻohe pala mai nā reagents kemika, no laila kūpono loa nā hale PTFE no nā bearings pale pala, nā bearings non-magnetic, nā bearings mīkini rocket, a pēlā aku.

 

3) Hale PPS. He paʻakikī kiʻekiʻe ko PPS a he paʻakikī kiʻekiʻe, kahi mea kakaikahi i nā plastics ʻenekinia, ʻoi aku hoʻi i nā mahana kiʻekiʻe, loaʻa nō iā ia ke kūpaʻa kemika maikaʻi (ʻo ka lua wale nō ma hope o PTFE), ʻoiai i loko o ke kaiapuni o ka ʻaila compressor, ka ʻaila gear, ka refrigerant ammonia a me nā wahi ʻē aʻe, ʻo kona ikaika, paʻakikī, paʻakikī, kūpaʻa ʻaʻahu a me nā hana piha ʻē aʻe he maikaʻi loa ia, no laila hoʻohana maikaʻi ʻia nā hale PPS i nā bearings e like me nā compressors wikiwiki kiʻekiʻe.

 

ʻO nā pā palaki ʻenekinia i hoʻohana nui ʻia no ke alakaʻi ferrule:

 

1) ʻO ka pā Phenolic, me ka haʻahaʻa o ka nui o nā mea, ka hoʻokomo ʻana o ka aila porous a me ka omo ʻana o ka aila, ka coefficient friction haʻahaʻa a me nā waiwai maikaʻi loa ʻē aʻe, kūpono loa ia no ke alakaʻi ferrule i ka wā o ka hana wikiwiki, ʻo ia ka pā "maʻamau" o nā bearings precision wikiwiki i hōʻike ʻia e nā bearings spindle mīkini.

 

2) ʻO ka hale PEEK, me ka hui kūpono o ka ikaika a me ka elasticity, ke kūpaʻa wela kiʻekiʻe maikaʻi loa a me nā ʻano friction paheʻe, ke kūpaʻa luhi koʻikoʻi loa ma lalo o ke kaumaha alternating (ʻo ka mea maikaʻi loa i nā plastics ʻenekinia, hoʻohālikelike ʻia me nā mea alloy), a me ke kūpaʻa dimensional kiʻekiʻe (he liʻiliʻi ka nui o ka hoʻemi ʻana o ka injection molding, no laila ʻoi aku ka kiʻekiʻe o ka pololei o ka hana ʻana ma mua o nā plastics ʻenekinia maʻamau, a ʻaʻole nui ka hopena o nā loli o ka mahana a me ka haʻahaʻa i ka nui o ka huahana, no laila hiki iā ia ke hoʻokō i nā koi o ka hoʻohana pololei kiʻekiʻe). I nā bearings mīkini hana, nā bearings wikiwiki ultra-kiʻekiʻe i hoʻolālā ʻia no ka lubrication aila a me ke kinoea (ka waiwai DMN a hiki i ka 3.0 × 106 mm · r/min) me ka piʻi haʻahaʻa o ka mahana a me ka holo haʻahaʻa ʻaʻole hiki ke hana hou ʻia (NRRO), ʻoi aku hoʻi ma lalo o ke kūlana o ka micro lubrication.

 

3) ʻO ka hale PI, me nā pono o ke kūpaʻa ʻana i ka ʻaʻahu, ka lubrication ponoʻī a me ka ikaika kiʻekiʻe, ua hoʻohana nui ʻia kona ʻano porous i nā gyromotors mokulele lōʻihi, nā mea hoʻokele, nā huila momentum a me nā bearings ʻē aʻe ma hope o ka mālama ʻana i ka vacuum immersion.

 

Nā BearingsʻO ka nui like o ka hoʻākāka a me ka pae hoʻomanawanui he hopena koʻikoʻi i kā lākou hana wikiwiki ke hoʻohana ʻia nā ʻano like ʻole o nā cages: e lawe ana i nā bearings ball contact angular ma ke ʻano he hoʻohālikelike kuhikuhi, ʻo ka wikiwiki hope loa o nā bearings cage paʻa he hapalua wale nō ia o nā bearings cage phenolic, ʻoiai ʻo ka wikiwiki hope loa o nā bearings cage i paʻi ʻia he 80% o nā bearings cage paʻa.

 

E hoʻohuli i ka ferrule e like me ke kuhikuhihāpai ʻana

Ke wili ke apo o loko a paʻa ke apo o waho, alakaʻi ke apo o loko; Ke wili ke apo o waho a paʻa ke apo o loko, alakaʻi ke apo o waho; Ke wili nā apo o loko a me waho, alakaʻi ke kino ʻōwili.

 

ʻO kēia ma muli o ka ʻoiaʻiʻo i ka wā e wili ai ke apo o loko, hoʻohana ʻia ke apo o loko e alakaʻi, a ʻo ka friction ma waena o ke apo o loko a me ka hale paʻahao ke kumu o ka ikaika hoʻokele o ka hale paʻahao; ʻO ka friction i hana ʻia e ke alakaʻi apo o waho ke kumu o ke kū'ē ʻana i ka hale paʻahao. Ke wili ke apo o waho, pono e hoʻohana ʻia ke apo o waho. Ke wili nā apo o loko a me waho, he mea kūpono ke hoʻohana i kahi mea wili e alakaʻi, a pēlā nō hoʻi.

 

ʻO nā pae hoʻohālikelike i luna aʻe nei ua noʻonoʻo wale ʻia mai ka manaʻo maʻalahi o ka friction, a pono e noʻonoʻo pono ʻia ke koho ʻana i ka hoʻohana maoli. E lawe i ka wili ʻana o ke apo o loko a me ke apo o waho i paʻa i nā noi hana ma ke ʻano he laʻana: hoʻohana nui ʻia ke alakaʻi apo o waho i ka wikiwiki kiʻekiʻe, no ka mea, ʻoi aku ka paʻa o ke apo o waho paʻa, a me nā pono koʻikoʻi ʻē aʻe i ʻōlelo ʻia ma luna; ʻoiai he hana kaumaha a nui paha ka nuinā mea e hāpai anaua alakaʻi nui ʻia e nā apo o loko e hōʻemi i ka torque hoʻomaka a me ka torque rotational o ka hale paʻahao.

 

Wahi a ka ferrule me ka flange

Ke loaʻa i ke apo waho kahi flange, alakaʻi ke apo waho (e like me nā bearings cylindrical NU type); Ke loaʻa i ke apo o loko kahi flange, alakaʻi ke apo o loko (e like me nā bearings cylindrical cylindrical N-type); Loaʻa i nā ferrules ʻelua nā flanges, i hoʻoholo ʻia e like me ke kau ʻana, ka hana a me nā koi mālama o ka bearing. Aia kekahi mau bearings cylindrical ultra-precision i hoʻomohala ʻia e Schaeffler ma Kelemania e like me ka mea i hōʻike ʻia ma ke Kiʻi 5, ʻaʻole hoʻohana i nā flanges ferrule ma ke ʻano he ʻili alakaʻi. No ka mea, ʻoi aku ka paʻakikī o ka nui o ka raceway, ka pololei o ke ʻano a me ka ʻili ma mua o nā koi o ka lihi ferrule, ʻoi aku ka pololei a me ka laumania o ke alakaʻi ʻana o ka hale paʻahao. Hoʻohana ʻia ke alakaʻi ferrule raceway e hoʻonui i ka helu o nā wili, ʻo ia hoʻi, ka hiki ke hāpai i ka bearing, a hiki i ke kūlana o ka hale paʻahao ke mālama i ka piko o ka mea wili (ke alakaʻi ʻia ke apo o waho) a i ʻole ka lalo (ke alakaʻi ʻia ke apo o loko) e hoʻokō i ka hope loa o kona anawaena o loko a me waho.
