                一.机架♂的选用原理

                1.机架的选用,原则上是根据乐虎国际app输出轴径的大小来确定机架幸好,只要接口→形式及安装尺寸相符,乐虎国际app的输出轴大小在一定范围内可以对机架型号上下浮↑动.若选用乐虎国际app的安装尺寸与机架不】符,在一定范围内我们公司也可以对机架上法兰进行调整与乐虎国际app々联接,满足用户需求.

                 

                2.无支点◥机架.机架本身无轴的支撑点,搅拌轴是以乐虎国际app输出轴的两个支承轴为受力支点,可用于□传递小功率,不受或只受较小轴向负荷,搅拌ㄨ不太强烈的搅拌装置.搅拌轴与∮乐虎国际app的联接必须用刚性联轴器.特别是以JQ型夹壳联轴器◆为好.

                 

                3.单支点机架,具备下列条件之一者,选用单支点↓机架为好.

                (1)搅拌容器设置底轴╱承,作▽为一个受力支点;

                (2)轴封本体没有轴承(包括刚』性衬),作为一个受力支点(受力⌒ 程度按轴封要求规定);

                (3)搅拌容∏器内,轴中部设有导向轴承,作为一个受力支点(即中间轴承).

                     当具备上述条件的≡搅拌轴,在∑选用单支点机架时,搅拌轴与乐虎国际app之间的联轴器须选用HL型弹性柱销联轴器.

                     在实际应用中常用刚性联轴器代替弹性柱销联轴器联接搅拌轴与乐虎国际app输出轴,取消底轴或中间轴承等支点.这样使用简化了↑单支点支架的应用条件,但只适宜于搅拌不强烈,功率较小,对轴承负々荷较小的场合.这时联轴器应选用GT型刚性联轴器◥,以☆利轴向尺寸方面的微量调整,原则上不能用JQ型夹壳联轴器,若采用了夹壳联轴器,则必须对支点的轴承结构进行变动,采用带紧定的锥孔︼调心滚子轴承,或取消夹壳联轴器⌒中的吊环,使搅拌轴的轴向位置◣有适当调整的余地.

                 

                4.双支√点支架,不宜于选用无支点.单支点机架时,应选用★双支点机架.但选用的双支点机架下支点轴承结构采用带紧定套的锥孔调心滚ξ子轴承,便利于安装维修,且搅拌轴与乐虎国际app之间的联接必须选用柱销联轴器.
