iavKev hloov kho hniav profile yog ib qho tseem ceeb ntawm kev tsim iav, txhim kho kev ua haujlwm los ntawm kev txo cov suab nrov, kev co, thiab kev ntxhov siab. Kab lus no tham txog cov ntsiab lus tseem ceeb thiab cov kev xav tau koom nrog hauv kev tsim kho cov iav hniav profile.

1. Lub hom phiaj ntawm Kev Kho Hniav Profile

Kev hloov kho hniav profile feem ntau yog siv los them nyiaj rau kev sib txawv ntawm kev tsim khoom, misalignments, thiab elastic deformations nyob rau hauv load. Lub hom phiaj tseem ceeb suav nrog:

• Txo qhov kis tau tus mob yuam kev
• Minimizing iav suab nrov thiab kev co
• Txhim khu kev faib khoom load
• Ua kom cov iav lifespan Raws li lub ntsiab txhais ntawm lub meshing nruj ntawm lub iav, lub elastic deformation ntawm cov iav hniav tuaj yeem kwv yees los ntawm cov qauv hauv qab no: δa - cov hniav elastic deformation, μm; KA - Siv yam khoom, xa mus rau ISO6336-1; wt – load ib chav hniav dav, N / mm, wt = Ft / b; Ft - tangential quab yuam ntawm iav, N; b - zoo hniav dav ntawm iav, mm; c' - ib khub hniav mesh txhav, N / (mm·μm); cγ - Qhov nruab nrab meshing tawv, N / (mm·μm).Spur iav

Bevel iav

• Tswv yim nyem: Tshem tawm cov khoom los ntawm qhov kawg ntawm cov hniav iav kom tsis txhob cuam tshuam thaum lub meshing.
• Hauv paus nyem: Hloov kho cov hauv paus ntsiab lus kom txo tau kev ntxhov siab concentration thiab txhim khu lub zog.
• Lead Crowning: Siv me ntsis curvature raws tus hniav dav kom haum rau misalignment.
• Profile ntawm Crowning: Taw qhia curvature raws qhov involute profile kom txo tau qhov kev sib cuag ntawm ntug.

3. Tsim kev suav

Kev hloov kho cov hniav profile feem ntau yog suav nrog kev tshuaj ntsuam xyuas, simulations, thiab kev sim validation. Cov nram qab no parameter yog xam:

• Hloov pauv tus nqi (Δ): Qhov tob ntawm cov khoom raug tshem tawm ntawm cov hniav, feem ntau yog li ntawm 5 mus rau 50 microns nyob ntawm qhov chaw thauj khoom.
• Load Distribution Factor (K): Txiav txim seb qhov kev sib cuag li cas yog faib thoob plaws cov hniav hloov.
• Transmission yuam kev (TE): Txhais raws li qhov sib txawv ntawm cov lus tsa suab tiag tiag los ntawm cov lus tsa suab zoo tshaj plaws, txo qis los ntawm kev hloov kho profile kom zoo.
• Finite Element Analysis (FEA): Siv los simulate kev ntxhov siab faib thiab siv tau cov kev hloov kho ua ntej ntau lawm.

4. Kev txiav txim siab tsim

• Load xwm txheej: Tus nqi ntawm kev hloov kho nyob ntawm qhov kev thov load thiab xav tau deflections.
• Manufacturing Tolerances: Precision machining thiab sib tsoo yuav tsum ua kom tau raws li qhov xav tau hloov kho.
• Khoom Khoom: Lub hardness thiab elasticity ntawm cov ntaub ntawv iav cuam tshuam rau kev ua tau zoo ntawm kev hloov kho profile.
• Kev ua haujlwm ib puag ncig: High-speed thiab high-load daim ntawv thov yuav tsum tau hloov ntau yam.

5. Kev hloov kho hniav profile yog qhov tseem ceeb rau kev ua kom lub zog ua haujlwm zoo, txo cov suab nrov, thiab txhim kho cov kav ntev. Kev hloov kho kom zoo, txhawb nqa los ntawm kev suav thiab simulations, ua kom lub neej ntev thiab kev ua haujlwm ntawm cov iav hauv ntau yam kev siv.

Los ntawm kev txiav txim siab txog kev thauj khoom, cov khoom siv, thiab cov txheej txheem tsim khoom, cov kws ua haujlwm tuaj yeem ua tiav cov iav kev ua haujlwm zoo thaum txo cov teeb meem kev ua haujlwm.
