一、機架系列及選用原則
The Series Frames and Selection Principle.
1.機架的選用，原則上是根據減速機輸出軸徑的大小來確定機架型號，只要接口形式及安裝尺寸相符，減速機的輸出軸大小在一定范圍內可以對機架型號上下浮動。若選用帶接板機架，減速機的安裝尺寸與機架不符，在一定范圍內我廠也可以對接板進行調整與減速機聯接.滿足用戶要求。
2.無支點機架。機架本身無軸的支承點，攪拌軸是以減速機輸出軸的兩個支承軸為受力支點，可用于傳遞小功率，不受或只受較小軸向負荷.攪拌不太強烈的攪拌裝置。攪拌軸與減速機聯接必須用剛性聯軸器，特別是以JQ型夾殼聯軸器為***佳。
3.單支點機架。具備下列條件之一者，選用單支點機架為***佳。
(1)攪拌容器設置底軸承，作為一個受力支點:
(2)軸封本體設有軸承(包括剛性襯套).作為一個受力支點(受力程度按軸封要求規定):
(3)攪拌容器內，軸中部設有導向軸承，作為一受力支點(即中間軸承)。
當具備上述條件的攪拌軸.在選用單支點機架時.攪拌軸與減速機之間的聯軸器須選用HL型彈性柱銷聯軸器。
在實際應用中常用剛性聯軸器代替彈性柱銷聯軸器聯接攪拌軸與減速機出軸，取消底軸承或中間軸承等支點。這樣使用，簡化了單支點支架的應用條件，但只適宜于攪拌不強烈，功率較小，對軸承負荷較小的場合。這時聯軸器應選用GT型剛性凸緣聯軸器，以利軸向尺寸方面的微量調整:原則上不能用JQ型夾殼聯軸器，若采用夾殼聯軸器，則必須對支點的軸承結構進行變動，采用帶緊定套的錐孔調心滾子軸承，或者取掉夾殼聯軸器中的懸吊環，使攪拌軸的軸向位置有適當調整的余地。
4.雙支點機架。不宜于選用無支點，單支點機架時，應選用雙支點機架。但選用的雙支點機架下支點軸承結構帶緊定套的錐孔調心滾子軸承便利于安裝維修.且攪拌軸與減速機之間的聯接必須選用HL型彈性柱銷聯軸器。
1. The principle of selection frame. In principle we could choose the frame type of output
shaft diameter according to the interface mode and the installation dimensions. The output shaft could float according to the frame type. In order to meet the customers' requirement we could adjust the joining of the panel and the reducer at some range if the installation size is not matched with the frame when select the frame with Plug board.
2. The frame without support. There is no supporting points of the reducer's own frame.
The mixer axle which is supported by the two supporting bearings of the reducer's output shaft could be used in transmitting the small power, not accepted or minor accepted the with axial load.
3. Single-support of frame. You'd better select the single-support frame when the condition is as following:
(1). The agitator tank is set up a bearing as a supporting point.
(2). The reality gland seal (including the rigidity shel) is set up a bearing as a force supporting. (the forcing degree is sized according to the gland seal requirement).
(3). There is setting a lower shoe bearing at the center axial as a forcing support (namely center bearing).
The mixer shaft and the reducers' coupling should select the HL type spring Cylinder pin coupler when we use the single point frame which meet the above conditions' mixer shaft.
Actually, we usually use the rigidity coupling instead of the spring cylinc couple the mixer shaft and the output shaft. Canceling the supporting point of foot bearing andthe center bearing. Simplify the usage conditions of single supporting frame.
It is only suitable in these conditions of de-mightiness, minor power, small axial load. In order to have the minor adjustment of the axial dimension we should select the GT type rigidity flange coupling. In principle, the JQ type splint shell coupling isn't allowed to use. In order to have some adjustment leeway of the mixer axis, it is necessary to have the changeable of the bearing construct and use the cone-socket roller bearing with fasten ring or use the suspension ring taking off the splint coupling.
(4). Double-support of frame. We should select the double supporting point frame when non-support point or single-supporting point frame isn't suitable. In order to maintenance ease, the double-supporting point bearing construct which with the cone-socket roller bearing could be used. The coupling which between the mixer shaft and the reducer should select the NL type spring cylinder pin coupler.
