Shaft-hub connector, gear coupling and manufacturing method for a shaft-hub connection

摘要

There are already known in the art toothed couplings, the entrainment is assembled from a drive plate and an inner ring gear. This has the background that a hobbing method is used in the prior art for the production of the internal gear ring, which has a toothing according to DIN 5480. However, this procedure requires a double clamping of the parts and a subsequent step for connecting the internal gear with the drive plate. The same must be done at the counterpart to the shaft. The invention instead proposes to form a circular arc toothing. This makes it possible to process the individual tooth elements in a single clamping both by turning first, then by milling. It eliminates an additional clamping and at the same time the step of assembling the items. As a result, a considerably cheaper production of the toothed coupling is made possible.
