TY系列同軸式硬齒面齒輪減速器概述ZB J19009-88
概 述:
本產(chǎn)品按ZBJ19009-88標(biāo)準(zhǔn)制造鳍置。產(chǎn)品為輸入义钉、出軸位于同一軸線的全漸開線外嚙合齒輪傳動結(jié)構(gòu)障昆。主要傳動零件采用優(yōu)質(zhì)合金鋼材質(zhì)娇裁。齒輪經(jīng)滲碳淬火磨齒工藝制造查坪,精度為GB10095-88.6級吮炕。產(chǎn)品具有體積小、承載能力高醉锄、壽命長乏悄、噪音低、效率高等優(yōu)點恳不。
用途和適用范圍
產(chǎn)品可通用于冶金褥辰、礦山、運輸麸河、能源河美、建材、輕化等行業(yè)的機械傳動。其適用范圍如下:
配用Y系列三相異步電機祷燥,輸入轉(zhuǎn)速1500r/min枕调,電機安裝形式為B5或B35(對配用6級電機、變速調(diào)速電機翁乌、防爆電機等作非標(biāo)形式具體協(xié)商)堪锌;
用于水平或前后傾角不大于20°位置安裝;
環(huán)境溫度為-40~45℃蒙搅。低于0℃時啟動前應(yīng)予熱潤滑油至8℃以上肺疾。高于45℃時應(yīng)結(jié)合熱功率校核潘尿,采取相應(yīng)措施届慈。
