QJ-T型起重機(jī)套裝式減速機(jī)JB/T8905.4-1999產(chǎn)品簡介
起重機(jī)減速器主要用于起重機(jī)的起升、運行、回轉(zhuǎn)和變幅四大機(jī)構(gòu)中。 我國目前常用的起重機(jī)減速器按齒面硬度分有軟齒面、中硬齒面和硬齒面齒輪減速器,按安裝方式分有臥式、立式、套裝式、懸掛套裝式等。 起重機(jī)減速器因為是間歇式、周期重復(fù)工作。減速器發(fā)熱相對連續(xù)型工作的要好些,但是經(jīng)常起制動慣性載荷較大。因此輪齒的彎曲強度的安全系數(shù)較高,特別是用于起升和變幅機(jī)構(gòu)。直接影響人身和設(shè)備安全更應(yīng)如此。
