JAI large flange rack < 69 standard >, JAII < 69 bb1 rack. Frame itself without shaft bearing point, stirring shaft is two supporting shaft reducer output shaft for force protection, can be used to transfer small power, not or only by small axial load is not too strong, stirring device.

The coupling of mixing shaft and reducer must be used with a rigid coupling, especially with JQ type clamshell coupling.

JAI large flange frame < 69 standard >, JAII > < 69 standard rack is suitable for the cycloidal reducer coupling, rigid coupling, the coupling JA type straight hole, the coupling with A straight hole or B type cone hole, taper of 1:20 coupling. The frame is not supported by the axial force of the reactor.

Reducer selection of supporting frame, in principle is according to the size of the diameter of axle reducer output to determine the frame model, as long as the interface form and installation size, speed reducer output shaft size can within a certain range of frame model.

Single fulcrum frame with one of the following conditions, the single support frame is the best.

The mixing container sets the bottom bearing, as a bearing support;

The shaft seal body has bearing (including rigid lining), as a bearing force (the force degree is required by the shaft seal);

In the mixing vessel, the center of the shaft is equipped with a guide bearing, as a bearing bearing (i.e., intermediate bearing).

When the mixing shaft with the above conditions is adopted, the coupling between the mixing shaft and the decelerating machine shall be selected by the type of HL type elastic pin coupler.

In practical application, rigid couplings are used to replace the shaft of the coupling of elastic column pin couplings and the shaft of the reducer, and the bottom bearing or intermediate bearings are cancelled

Fulcrum. In this way, the condition of the single support bracket is simplified, but it is only suitable for the situation where the agitation is not strong and the power is small and the bearing load is small. Should choose the GT type rigid coupling, the coupling and axial size of minor adjustments, in principle cannot use JQ coupling clamp shell, shell coupling, if used, must be conducted to the fulcrum bearing structure changes, the set of pitch cone roller bearing, or take the clamp shell coupling in the rings, the stirring shaft axial position with proper adjustment.
