The selection of the rack, in principle, to ensure industry based on the size of the reducer output shaft of the rack model, as long as the interface to form and installation dimensions match the gear unit output shaft size within a certa in range can fluctuate rack model . If the selection of the gear unit installation dimensions and rack does not match the company within a certain range can also be rack flange to adjust the connection with the reducer to meet user requirements.
Two fulcrum rack. Rack itself without shaft bearing, stirring shaft is two and a support shaft of the reducer output shaft is affected by the force of the fulcrum can be used to pass the low-power, free or subject only to a small axial load, stirring is not particularly strong stirring device. Stirring shaft and reducer connection must use a rigid coupling, in particular, is a JQ type clamp coupling is the best.
3 single fulcrum rack, with one of the following conditions, the choice of a single fulcrum rack is the best.
(A) set the end of the mixing container bearing, as a fulcrum by force;
(2) shaft seal body has a bearing (including rigid lining), as a fulcrum by force (the degree of force shaft seal requirement s of the regulations);
(3) mixing container axis central with a guide bearing, as a force fulcrum (ie, intermediate bearing).
Stirring shaft with the above conditions, in the selection of single fulcrum rack, coupling between the stirring shaft and reducer are required to use the HL type elastic pin coupling.
Commonly used in the practical application of rigid coupling instead of the elastic pin coupling connection stirring shaft and the reducer output shaft, the abolition of the end bearing and intermediate bearing fulcrum. So using a simplified single fulcrum bracket conditions, but only suitable for mixing is not strong, less power, smaller bearing load situations. At this coupling should use a rigid coupling GT, Lee axial dimensions of the micro adjustment, in principle, can JQ type clamp coupling, the use of the clamp coupling, it must be the bearing of the fulcrum structure changes, the use of self-aligning roller bearings with adapter cone, or removing the clip rings in the shell coupling, so that the axial position of the stirring shaft room with appropriate adjustments.
4 dual fulcrum rack, should not be in the selection of non-pivot, single fulcrum rack, you should use a double-pivot rack. Optional dual fulcrum rack pivot bearing structure using the tapered bore self-aligning roller bearings with adapter sleeve to facilitate the installation and maintenance, and stirring the connection between the shaft and the reducer must be selected HL type elastic pin coupling.
