1.減速器的分類、應(yīng)用范圍Classification and application scope of decelerator

QY型系列減速器包括QYS型(三支點(diǎn))和QYD型(底座式)兩個(gè)系列起重機(jī)用硬齒面減速器。它有三級，四級和三四級結(jié)合型三種，其結(jié)構(gòu)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.

此減速器主要用于起重機(jī)各有關(guān)機(jī)構(gòu)，也可用于運(yùn)輸、冶金，礦山，化工及輕工等機(jī)械設(shè)備的傳動(dòng)中。其工作條件為:

1)齒輪圓周速度不大于20m/s;

2)高速軸轉(zhuǎn)速不大于1500r/min;

3)工作環(huán)境溫度為-40'C ~ +45'C;

4)可正反兩向運(yùn)轉(zhuǎn)。

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.
