Internally-toothed gears - Import export

Milled toothing, straight teeth engagement angle 20°, bright. Outside diameter extruded, tolerance h9. Note The gear rack teeth are cut using a hob mill. This results in minus tolerances for dimensions H and H1 up to module 2 0.2 mm. module 2.5 to 3 0.3 mm.

Milled toothing, straight teeth. Engagement angle 20°, bright. Note The gear racks are suitable for mounting in series.

Injection moulded, straight teeth. Engagement angle 20°. Machined bore. Polyacetal, white. Polyketone, ivorytone. Note Polyacetal Standard material with high hardness grade and low coefficient of friction. Polyketone Material with significantly longer service life, higher power transmission and greater security against tooth breakage due to the extraordinarily high wear resistance and very good tribological properties. Can be used under water and other media. Injection moulded gear wheels may have internal manufacturerelated cavities. These may become visible during drilling or broaching. They do not impair the function. The torques specified in the tables relate exclusively to the toothing.

Milled toothing, straight teeth. Engagement angle 20°, bright. Note Up to 48 teeth with hub one side, from 50 teeth supplied as disc form. The spur gears have a centre bore or pilot hole (this can vary due to manufacturing methods). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore with which the spur gears are supplied. This pilot/centre bore can be amended by the customer to produce a reamed bore, reamed bore with keyway or a tapped hole. Alternatively, customers can also use bushes to reduce the bore diameter.
