babbitt yog dab tsi?
Babbitt yog a dawb hlau alloy uas tau patented los ntawm Isaac Babbitt xyoo 1839. Thaum lub sij hawm, lub sij hawm Babbitt tau siv rau lwm yam dawb hlau zoo xws li tin, tooj liab thiab antimony. Cov hmoov txhuas tuaj yeem muab ntxiv rau qhov chaw ntawm lub tin.
babbitt txhais li cas?
: ib tug neeg thiab tshwj xeeb tshaj yog ib tus neeg lag luam lossis tus txiv neej ua haujlwm uas ua raws li kev xav tsis thoob rau cov txheej txheem nruab nrab.
babbitt bearing khoom yog dab tsi?
Babbitt bearings yog lub tes tsho bearings ua los ntawm qee hom alloys, uas tau yaj thiab nrum los tsim cov kabmob nto. Lub Babbitt bearing tau tsim nyob rau hauv 1839 los ntawm ib tug neeg Asmeskas hu ua Issac Babbitt. Thawj hom Babbitt cov kabmob uas muaj cov kabmob muaj xws li tin, antimony thiab tooj liab.
Koj tuaj yeem qhia tau li cas yog hlau yog babbitt?
Babbitt hlau yog tus yam ntxwv los ntawm nws ua haujlwm rau gallingBabbitt hlau yog mos thiab yooj yim puas, uas qhia tias nws yuav tsis haum rau cov kabmob nto. Txawm li cas los xij, nws cov qauv yog tsim los ntawm cov pob zeb me me uas tau tawg nyob rau hauv cov hlau softer, uas ua rau nws cov hlau matrix sib xyaw.
