ʻO ka hoʻāʻo ʻana e hoʻololi i ka hoʻoheheʻe ʻana me ka hoʻopili ʻana i ka ʻōwili ʻia ʻike ʻia ua hoʻokipa ʻia i ka wā prehistoric. ʻO ka pā kiʻi he kiʻi pena ma ʻAigupita. Ke lawe ʻia nei kekahi pōhaku nui ma nā lāʻau ʻōwili i waiho ʻia ma lalo. ʻO ke ʻano o ka lawe ʻia ʻana o kēlā mau lāʻau i hoʻohana ʻia i ka ʻaoʻao mua e hōʻike pololei ana i ke ʻano o ka hana ʻana o ka ʻenekini holo kaʻa i loko o nā bearings linear motion i kēia lā.
ʻOiai ʻo ka rolling element linear motion bearings e ʻike i ko lākou kumu i ka wā kahiko, ʻaʻole lākou i hele maʻalahi i ka hoʻohana maʻamau ma ke ʻano he mechanical element a hiki i ka hoʻomaka ʻana o ke kenekulia 20, i ka wā i hoʻohana ʻia ai kēlā mau mea ʻōwili linear motion bearings e hoʻohana ana i nā pōpō kila no kā lākou neʻe laina pololei a maʻalahi hoʻi i ka noi i nā mīkini pololei.
ʻO ka mīkini kumu o ka mea ʻōwililaina neʻe lainaUa hoʻokumu ʻia i ka makahiki 1946 i ka wā i kūʻai ʻia ai kahi hui ʻAmelika, ʻo Thomson, i nā ʻōpala pōleʻa (he ʻano pōlele hou). Hiki ke ʻike ʻia ke kumu o nā alakaʻi laina o kēia lā (nā ʻāpana ʻōwili me nā kaʻa) ma kahi patent i hāʻawi ʻia ma Farani i ka makahiki 1932. ʻO kēia patent, ʻoiai e hoʻopili ana i nā hana koʻikoʻi āpau o nā alakaʻi laina, pono mau e kali no nā makahiki he mau makahiki ma mua o kā lākou noi noi ma ka mākeke. I loko o ia manawa, ua kūʻai kūʻai ʻia kekahi mau ʻāpana mīkini e hoʻohana ana i nā mea ʻōwili e like me nā pōpō pōlele a i ʻole nā splines. Ua lawe ʻia mai i ka mākeke nā ʻano ʻano like ʻole o nā puʻu kinipōpō (linear ball bearings), me nā bearings ʻano hāmama. I kēia manawa, nui nā mea hou a me nā hoʻomaikaʻi o nā ʻano like i hana ʻia i kaalakai laina.
mākou,PYGʻO Zhejiang Pengyin Technology Development Co., LTD, he ʻoihana ʻenehana kiʻekiʻe e kālele ana i ka noiʻi a me ka hoʻomohala ʻana i nā ʻāpana kiko o ka linear transmission a me ka hoʻolālā hou ʻana no nā makahiki he 20. mm.
Ka manawa hoʻouna: Mei-13-2024
