一、機架系列及選用(yòng)原則
The Series Frames and Selection Principle.
1.機架的(de)選用(yòng)，原則上是根據減速機輸出軸徑的(de)大(dà)小來(lái)确定機架型号，隻要接口形式及安裝尺寸相符，減速機的(de)輸出軸大(dà)小在一定範圍内可(kě)以對(duì)機架型号上下(xià)浮動。若選用(yòng)帶接闆機架，減速機的(de)安裝尺寸與機架不符，在一定範圍内我廠也(yě)可(kě)以對(duì)接闆進行調整與減速機聯接.滿足用(yòng)戶要求。
2.無支點機架。機架本身無軸的(de)支承點，攪拌軸是以減速機輸出軸的(de)兩個(gè)支承軸爲受力支點，可(kě)用(yòng)于傳遞小功率，不受或隻受較小軸向負荷.攪拌不太強烈的(de)攪拌裝置。攪拌軸與減速機聯接必須用(yòng)剛性聯軸器，特别是以JQ型夾殼聯軸器爲***佳。
3.單支點機架。具備下(xià)列條件之一者，選用(yòng)單支點機架爲***佳。
(1)攪拌容器設置底軸承，作爲一個(gè)受力支點:
(2)軸封本體設有軸承(包括剛性襯套).作爲一個(gè)受力支點(受力程度按軸封要求規定):
(3)攪拌容器内，軸中部設有導向軸承，作爲一受力支點(即中間軸承)。
當具備上述條件的(de)攪拌軸.在選用(yòng)單支點機架時(shí).攪拌軸與減速機之間的(de)聯軸器須選用(yòng)HL型彈性柱銷聯軸器。
在實際應用(yòng)中常用(yòng)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(zhè)樣使用(yòng)，簡化(huà)了(le)單支點支架的(de)應用(yòng)條件，但隻适宜于攪拌不強烈，功率較小，對(duì)軸承負荷較小的(de)場(chǎng)合。這(zhè)時(shí)聯軸器應選用(yòng)GT型剛性凸緣聯軸器，以利軸向尺寸方面的(de)微量調整:原則上不能用(yòng)JQ型夾殼聯軸器，若采用(yòng)夾殼聯軸器，則必須對(duì)支點的(de)軸承結構進行變動，采用(yòng)帶緊定套的(de)錐孔調心滾子軸承，或者取掉夾殼聯軸器中的(de)懸吊環，使攪拌軸的(de)軸向位置有适當調整的(de)餘地。
4.雙支點機架。不宜于選用(yòng)無支點，單支點機架時(shí)，應選用(yòng)雙支點機架。但選用(yòng)的(de)雙支點機架下(xià)支點軸承結構帶緊定套的(de)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(de)聯接必須選用(yòng)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.
