\"\"How do you maintain flexibility when adjusting gearboxes? Sometimes the adjustment of gearboxes in a frame has to be very accurate, for example when adjusting a pinion on a rack or when aligning an over-determined construction. In that case it would be easy to give the gearbox not a fixed position in the frame but to make the gearbox relative adjustable to the frame.<\/p>\n

<\/p>\n

Applying slotted holes<\/h2>\n

Normally you would position the gearbox through the centering edge -with tolerance g6 or h6- and fix with bolts. But in certain constructions or when adjusting a pinion, it is optimal not to fix the box in advance. This is easily achieved by so-called slotted holes.<\/p>\n

In the case of slotted holes, the bolt holes are elongated, as a result of which the flange of the gearbox can move relative to the machine frame. Almost everyone has used this principle; when tensioning a bicycle chain you can, due to the (open) slotted hole, shift the wheel in such a way that the chain is nicely tight.<\/p>\n

\"\"Front plate with slotted holes<\/h2>\n

If slotted holes are practical for you, then the centering edge does not make much sense since you do not center. That’s why Apex Dynamics has engineered a front-plate that is equipped with slotted holes and a flat front! Ideal for making an adjustment against, for example, a flat machine frame. And because of this construction method, the center of the shaft is close to the flange, which means that the radial forces can be absorbed better.<\/p>\n

This front plate can be mounted AE- and PEII-series gearboxes and on the right-angle gearboxes AER and PEIIR. Drawings of these front plates can be made on request and adjusted individually.<\/p>\n
