一、QY型起重機用(yòng)硬齒面減速器
Hard tooth face decelerator for QY type hoist
1.減速器的(de)分(fēn)類、應用(yòng)範圍Classification and application scope of decelerator
QY型系列減速器包括QYS型(三支點)和(hé)QYD型(底座式)兩個(gè)系列起重機用(yòng)硬齒面減速器。它有三級，四級和(hé)三四級結合型三種，其結構簡圖見圖1。
QY series decelerator includes hard tooth face decelerator for type QYS (3-supporting- point) and type QYD (pedestal type) hoists. It has 3-step, 4 step and 3 and 4 combined type, see figure 1 for structural diagram.
此減速器主要用(yòng)于起重機各有關機構，也(yě)可(kě)用(yòng)于運輸、冶金，礦山，化(huà)工及輕工等機械設備的(de)傳動中。其工作條件爲:
1)齒輪圓周速度不大(dà)于20m/s;
2)高(gāo)速軸轉速不大(dà)于1500r/min;
3)工作環境溫度爲-40'C ~ +45'C;
4)可(kě)正反兩向運轉。
This decelerator is mainly used for each of related mechanism on the hoist, also for the transmission of mechanical equipment in transportation, meallurgy, mining, chemical industry, and light industry with working condition as follows:
1) Peripheral speed of the gear wheel does not exceed 20m/s;
2) Rotating speed of high speed shaft does not exceed 1500r/min;
3) Working ambient temperature is -40'C ~ +45'C ;
4) Both forward and backward rotation are available.
