Hu rau thaj tsam ntawm cov phaj siab thiab Rail siab faib
- Dab tsi yog thaj chaw sib cuag ib txwm nyob ntawm lub phaj nias thiab kev tsheb nqaj hlau, thiab ntsuas ntsuas nws li cas?
Thaj chaw tiv tauj ntawm kev tsheb ciav hlau zoo ib txwm nias daim hlau feem ntau {{mm², xws li foob pob nias cov paib; Kev Loj Siab - Ceev Railway Tshwj Xeeb Cov Hlau cheem cheem {}}}}}}}}}}}}}}}} Tom qab kev teeb tsa, tshem tawm nws . Cov xim cim ntawm qhov chaw nres tsheb, uas yooj yim thiab cov kev sib cav sib ceg (nrog rau thaj tsam (± 20mm²) - Precision nrhiav tau, xws li nias daim hlau hauv siab - nrawm kev tsheb ciav hlau yuav tsum muaj ntau tshaj lossis sib luag rau 960mm² kom ntseeg tau qhov tsim nyog tso tawm.

- Yuav ua li cas ntxiv rau thaj chaw tiv tauj ntawm cov phaj nias thiab cov tsheb ciav hlau?
Txhim kho cov duab ntawm nias phaj, tsim cov kev sib ze sib xws, tuaj yeem ua rau muaj kev sib tw ntawm lub dav hlau phaj, nce qhov dav los ntawm 80mm rau 100mm, thaj chaw tiv tauj yuav tau nce qib siab tshaj plaws {}}}}}}} . 3μm rau Ra3.2μm, can reduce contact loss due to surface unevenness, and the actual contact area increases by 5% - 10%, achieved by precision grinding process, with little cost increase but obvious effect. Controlling the installation torque, insufficient torque will reduce the contact area by 10% - 15%. Install Raws li cov kev cai tshwj xeeb (xws li · m {21} parsy) kom ntseeg tau tias lub phaj nias xwb txuas rau txoj kev tsheb nqaj hlau. RAIL DIST ANCT yuav tsum tau tshuaj xyuas ib hlis ib zaug, thiab kev kub siab - nrawm kev tsheb ciav hlau ib hlis ib zaug.
