Gears - Import export

Injection moulded, straight teeth. Engagement angle 20°. Axis angle = 90°. Machined bores from module 1.5. Polyacetal, white. Polyketone, ivory tone. 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. Bevel gear wheels are supplied as single components. To obtain a pair of bevel gear wheels, please order the specified mating gear as well.

Milled toothing, straight teeth. Engagement angle 20°, bright. Axis angle = 90°. Note for ordering Bevel gears are supplied singly. To obtain a pair of bevel gears, please order the specified mating gear as well.

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.

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. Due to the material properties, plastic gear racks are not straightened. L= nominal length 250 mm. The actual length is roughly a whole multiple of the pitch.

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

Milled toothing, straight teeth. Engagement angle 20°, bright. Note Up to 70 teeth with hub one side, from 80 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.

Zero backlash, torsionally rigid, resiliently flexible and maintenancefree full metal coupling for transmitting angle synchronous rotary movement. The innovative slit structure makes possible a very good axial, radial and angular flexibility with low reset force. Ideal for servomotors. Assembly Recommended shaft tolerances h7. On request Hub bores D1 and D2 with separate tolerance class or range. Note Procedure for enlarging predrilled bores D1/D2 Drill the bore out using a small as possible drill or milling cutter. Use a single point tool to turn or bore the hole out to its finished size. Ensure that the coupling is securely held during the machining process and that the drill feed is not too high. The cut depth should not exceed 0.5 mm and the feed for the single point tool should also be not too high.

Housing aluminium. Worm screw steel, worm wheel special brass. Version Housing anodised. Ball bearing with rubber sealing washer RS. Note Universally applicable and maintenancefree worm drive in one size with a centre distance of 20 mm and 7 different ratios. The housing is sealed to prevent grease leakage and keep dust out. These are left hand worm gears. The rotation direction on the shaft is arbitrary. smooth power transmission simple screw fastening quiet Note FR permissible radial force at FA=0 FA permissible axial force at FR=0

Worm screw steel. Worm wheel CuZn37Mn3Al2PbSiS40. Version Worm screw with righthand pitch, casehardened HV 620 – 700, flanks and hole ground. Note for ordering Wheels/screws can only be combined to form a worm gear if they have the same centre distance and transmission ratio. Note A worm gear consists of a worm screw (shaft) and a worm wheel. Suitable for forming worm drives with a 90° shaft angle. A worm drive enables very large speed reduction ratios with a single stage. The toothing has the flank shape K. The engagement angle is 15°. The worm gears are prebored. The stated T2 output torques are the permissible output torques on the worm wheel. These apply for an input speed of 2800 rpm of the worm screw. The worm gears are suitable for continuous operation at high speeds and high torques. Attention 22500171002 Screw polished only. 22500172002 Worm wheel with helical gear toothing.

Planetary gearing for stepper motors of the NEMA 23 and NEMA 34 size. Suitable for all mounting positions. Maintenancefree thanks to lifetime lubrication. The planetary gearing is selfcentring, equipped with a flange adapter system and axial length compensation.
