減速機(jī)技術(shù)資料：

減速機(jī)的主要產(chǎn)品類型和特點
減速機(jī)是一種由封閉在剛性殼體內(nèi)的齒輪傳動、蝸桿蝸輪傳動或齒輪—蝸桿傳動所組成的獨立部件。 其主要類型：齒輪減速機(jī)；蝸桿減速機(jī)；齒輪—蝸桿減速機(jī)；行星齒輪減速機(jī)。 
一、圓柱齒輪減速機(jī)
單級、二級、二級以上二級。布置形式：展開式、分流式、同軸式。
二、圓錐齒輪減速機(jī)
用于輸入軸和輸出軸位置成相交的場合。
三、蝸輪蝸桿減速機(jī)
主要用于傳動比i>10的場合，傳動比較大時結(jié)構(gòu)緊湊。其缺點是效率低。目前廣泛應(yīng)用阿基米德蝸桿減速機(jī)。
四、齒輪—蝸桿減速機(jī)
若齒輪傳動在高速級，則結(jié)構(gòu)緊湊；
若蝸桿傳動在高速級，則效率較高。
五、行星齒輪減速機(jī)
傳動效率高，傳動比范圍廣，傳動功率12W~50000KW，體積和重量小。
六、裝式減速機(jī)
七、組裝式減速機(jī)
八、多安裝式減速機(jī)
九、聯(lián)體式減速機(jī)
傳動比分配
傳動比分配的基本原則：
1 使各級傳動的承載能力近于相等；
2 使各級傳動的大齒輪浸入油中的深度大致相近；
3 使減速機(jī)獲得最小的外形尺寸或重量等。
減速機(jī)潤滑
一、傳動的潤滑
圓周速度v￡12m/s~15m/s的齒輪減速機(jī)廣泛采用油池潤滑，自然冷卻。為減少齒輪運動阻力和油升溫，浸入油中的齒輪深度以1~2個齒高為宜。
在多級減速機(jī)中應(yīng)盡量使各級傳動浸入油中深度近于相等。
為免太淺時激起沉降在箱底的油泥，應(yīng)保持齒頂圓距離箱底不低于30mm~50mm左右。
若減速機(jī)的工作平衡溫度超過90°C時，需采用循環(huán)油潤滑，或其它冷卻措施。
蝸桿圓周速度在10m/s以下的可采用油池潤滑。蝸桿在下時，油面高度應(yīng)低于蝸桿螺紋根部，并且不超過蝸桿軸的軸承的最低滾動體中心，以免增加功率損失。蝸桿圓周速度在10m/s以上的應(yīng)采用噴油潤滑。
二、軸承的潤滑
軸承的潤滑方法可根據(jù)齒輪或蝸桿的圓周速度來選擇：
1圓周速度在2m/s~3m/s以上時----飛濺潤滑
2圓周速度在2m/s~3m/s以下時----刮油潤滑
3轉(zhuǎn)速很高的軸承----壓力噴油潤滑
