DB、DC型減速器包括DBY二級硬齒面；DCY三級硬齒面；DBZ二級中硬齒面；DCZ三級中硬齒面；DBYK二級硬齒面空心軸式和DCYK三級硬齒面空心軸式六個系列減速器。高速級為弧齒錐齒輪，中低速級為圓柱齒輪。這種減速器具有承載能力大、傳動效率高、噪聲低、體積小、壽命長的特點，用于輸入軸與輸出軸呈垂直方向布置的傳動裝置，如帶式輸送機及各種運輸機械，也可用于煤炭、冶金、礦山、化工、建材、輕工和石油等各種通用機械的傳動中。其工作條件為：
1、 齒輪圓周速度≤20m/s；
2、 輸入軸轉(zhuǎn)速≤1500r/min；
3、 工作溫度為-40～45℃，當(dāng)環(huán)境溫度＜0℃時，啟動前潤滑油應(yīng)加熱到10℃。
