概述
QJY系列減速器為根據(jù)市場需求開發(fā)的硬齒面起重機減速器,全系列包括QJY(三支點支承式)、QJYD(地腳安裝)、QJYA(空心軸式)三大類十二種基本形式(具體形式見圖1)。
該系列減速器齒輪采用低碳合金鋼,齒面滲碳淬硬,磨削成形,具有承載能力大(較QJR、QJS減速器提高1.8~2.4倍)、傳動效率高、使用可靠、壽命長等優(yōu)點。
QJY系列減速器適用于起重機的各有關機構,也可用于運輸、冶金、礦山、化工、輕工等各種機械設備的傳動機構中。
減速器的工作條件符合下列要求:
a)減速器高速軸轉速不大于1500r/min。
b)工作環(huán)境溫度-40~+50℃。
c)可正、反兩向運轉。
