Yadda ake saita tsari mafi dacewa ga injuna ta amfani da bearings na ƙwallon lamba mai kusurwa?

Ga injinan tsaye inda ƙarfin axial yake a zahiri, mafi yawanbearings na ƙwallon lamba na kusurwaana amfani da su, wato, ana amfani da ƙarfin ɗaukar nauyin axial na jikin ɗaukar nauyi don daidaita ƙarfin axial na ƙasa wanda nauyin rotor na injin tsaye ya samar.

A cikin tsarin tsarin bearing na motar, bearing na ƙwallon hulɗa na kusurwa gabaɗaya suna taka rawar daidaita ƙarfin axial da kuma sanya bearing a lokaci guda; ko an sanya bearing na ƙwallon hulɗa na kusurwa a sama ko ƙasa, bearing ɗin suna daidaita axis ɗin ƙasa wanda nauyin rotor ɗin kansa ya samar. Ƙarfi, wato, lokacin da aka sanya bearing na ƙwallon hulɗa na kusurwa a ƙasan motar, bearing ɗin yana da tasirin ɗagawa sama akan rotor; kuma lokacin da aka sanya bearing a saman motar, bearing ɗin yana da tasirin jan hankali akan rotor. Saboda haka, ga injinan tsaye, galibi ana amfani da saitin bearing na ƙwallon hulɗa na layi ɗaya na kusurwa.

Daga nazarin ka'ida, bearings masu layi ɗaya na iya jure wa nauyin radial da nauyin axial mai hanya ɗaya. Kusurwoyin hulɗa na yau da kullun na wannan nau'in bearings sune 15°, 25° da 40°. Girman kusurwar hulɗa, girman ikon jure wa nauyin axial. Duk da haka, ƙaramin kusurwar hulɗa, mafi kyawun amfani da shi don juyawa mai sauri. Saboda haka, lokacin zaɓar kusurwar hulɗar bearings, ya kamata a yi la'akari da saurin motar sosai.

An raba bearings ɗin ƙwallon hulɗa na layi biyu zuwa sassa biyu: zobe na waje ɗaya da zobe na ciki biyu, da zobe na waje ɗaya da zobe na ciki ɗaya. A tsarin gini, an haɗa bearings guda biyu masu layi ɗaya a baya don raba zobe na ciki da zobe na waje, waɗanda zasu iya ɗaukar nauyin radial da nauyin axial biyu. Ana amfani da wannan nau'in bearings galibi a cikin sandunan kayan aikin injin, injunan mita masu yawa, injinan iska, famfunan mai, na'urorin compressor na iska, injinan bugawa, da sauransu.

A aikace-aikace na aiki, haɗin baya-da-baya (DB) da haɗin fuska-da-fuska (DF) na bearings na lamba mai layi ɗaya, da kuma bearings na layi biyu, na iya ɗaukar nauyin radial da nauyin axial na bidirectional. Haɗin bearings na lamba mai layi ɗaya (DT) wanda aka tsara a jere ya dace ne kawai don aikace-aikace inda nauyin axial na hanya ɗaya ya yi girma kuma nauyin da aka kimanta na bearing ɗaya bai isa ba.

A cikin ainihin yanayin amfani da motar, ban da ƙarfin axial yayin aikin motar, idan kuma ana buƙatar la'akari da rashin daidaiton tsakiyar shaft wanda abubuwan juyawa kamar shaft ko gida suka haifar, ana iya amfani da bearings masu siffar ƙwallo.
