Nyob rau hauv cov khoom siv automation, kis systems, hluav taws xob motors, cuab yeej fixtures, thiab precision sib dhos khoom,cov ncej(tsav shafts, mandrels, qhia shafts, nrhiav shafts, thiab stepped shafts) yog ib qho tseem ceeb Cheebtsam uas txiav txim lubprecision, stability, thiab kev pab lub neejntawm tag nrho lub tshuab.

Txawm hais tias tus ncej yuav zoo li yog ib qho yooj yim cylindrical tivthaiv, nws yog ib qho ntawm feem ntau qhov chaw ntawm kev yuav khoom:

Tsis txaus concentricity ua rau vibration thaum tig

Dimensional deviations ua rau kev ua tsis tiav

Qhov saum npoo tsis zoo ua rau hnav sai

Tsis txaus hardness ua rau khoov

Cov keyways tsis zoo los yog threads

Feem ntau, cov neeg muag khoom tsuas yog thov qhov ntawdkev cai qhov chaw tsis yog -rov qab, tawm tag nrho cov kev pheej hmoo nrog tus neeg yuav khoom.

Ib tug ncej yogtsis yog ib puag ncig bar. Nws cuam tshuam ncaj qhakis tau tus mob, concentricity, hnav tsis kam, sib dhos ua tau zoo npaum li cas, thiab tag nrho cov tshuab stability.

Nyob rau hauv kev cai machining, ncej Cheebtsam xav tauCov qauv nruj heev rau precision, ua, cov ntaub ntawv, thiab kev kho deg. Yog tsis muaj kev qhia meej meej, teeb meem yuav luag tsis muaj.

Common Procurement Pitfalls rau Shafts

Case 1: Kev Tswj Tsis Zoo Dimensional Tolerances

Ib lub chaw tsim khoom siv automation ib zaug yuav khoomcoj shaftsnrog xoob tswj txoj kab uas hla tolerances.

Qee cov ncej taunruj heev kom nias haum

Lwm tus yogdhau lawm, tsim kev tshem tawm ntau dhau thiab ua tsis tau raws li qhov yuav tsum tau ua kom raug.

Vim cov duab tolerances yogtsis meej, kev tsis sib haum xeeb tshwm sim ntawm tus neeg yuav khoom thiab tus neeg muag khoom, thiab tag nrho cov khoom yuav tsum tau muab pov tseg thiab rov ua dua tshiab.

Case 2: Cov khoom siv tsis zoo, hardness, lossis kev kho deg

Ib lub tuam txhab tsim khoom tau xajnrhiav shaftsthiab tsuas yog thov kom lawv ua tau "surable."

Yuav kom yeej qhov kev txiav txim ntawm tus nqi qis, tus neeg muag khoom sivcov khoom txheem yam tsis muaj kev kho cua sov, hla quenching thiab tempering, thiab tshem tawm nto tiav.

Tom qab luv - siv sijhawm:

Ncejkhoov

Ntohnav sai

Rust tshwm

Qhov no txo ​​qis cov cuab yeej siv lub neej.
Vim lubdaim ntawv cog lus tsis tau qhia txog qib khoom, hardness, lossis kev kho saum npoo, tus neeg yuav khoom tsis muaj lub hauv paus rau kev lav ris.

Vim li cas Cov Cheebtsam Ua Haujlwm Feem Ntau Ua Rau Kev Sib Tham?

Tsis tiav Engineering Drawings

Ntau cov duab kos tsuas yog qhiatxoj kab uas hla thiab ntev, thaum tso tseg:

Tsis Muaj Cov Qauv Tshuaj Ntsuam Xyuas Kom Zoo

Yog tsis muaj cov qauv kev cai, tsis muaj kev pom zoo rau:

Yuav tsum ntsuas li cas

Yuav ua li cas deg roughness yuav tsum tau xyuas

Yuav ua li cas hardness yuav tsum tau soj ntsuam

Txhua yam uakev txiav txim siab.

Kev sib txuas lus sib txawv hauv kev tsim khoom

Pab pawg neeg yuav khoom yuav tsis nkag siab tag nrho cov kev xav tau ntawm lub tshuab ua haujlwm, thaum cov neeg muag khoom tsis tuaj yeem nkag siab meejdaim ntawv thov scenario.

Thaum ib qho tsis raug tsim tawm,cov nqi rework yog siab.
