* The worm gear of the A35U3 gear set can also be delivered as a crossed helical gear, pressure angle 20°.
All worms and worm gears stocked right hand only.
Worm made of case hardened and ground steel (HV 620 – 700). Lead content is ≤0.1 percent by weight.
Worm gear made of CuZn37Mn3Al2Si. Lead content is ≤0.1 percent by weight.
Phenolic worm gears do not have the pre-drilled start for a pin. The outside diameter of the phenolic gear hub is 18 mm.
On request worm gears can be made of plastic or HGW 2083.
The output torque rating (T2) applies to the initial speed of 2800 rpm at the worm (shaft).
The efficiency values (see table in worm gear set catalog) are guidelines. The bearing, lubrication, speed, and installation, in addition to the lead angle, can influence efficiency.
Gears may be combined only with worms of the same axial distance and with the same transmission ratio.
Worms or worm gears from other manufacturers may not be paired with the counterpiece from Framo Morat. It is almost always necessary to adjust the toothing specifications.
All dimensions can be adapted upon request.
