Worm gear sets

Framo Morat's standard catalog of worm gear sets ranges from 20 to 135 mm in diameter and from 17 to 80 mm in axial distance. In addition, we offer custom worm gear sets with diameters up to 300 mm and center distances up to 210 mm.

Material:

The worm is case-hardened; the bore and worm flanks are ground. The standard worm wheel is made of VL22, a copper-zinc alloy with aluminum, silicon and manganese additions. This is a special quality from the CuZn40Al2 group according to DIN 17660 for sliding purposes (new product according to EN: CuZn37Mn3Al2PbSi). The aluminum content makes it very chemically resistant.

Plastic worm wheels

Due to poor thermal conductivity, plastic worm wheels are only suitable for low sliding speeds of < 1.5 m/s and medium tooth flank loads. The worm must be hardened and must have ground flanks. The torque capacity of plastic worm gears is about 60% of that of comparable bronze worm gears (this applies to use with mineral grease).

Bronze worm gears

Cu Sn 12 DIN 1705

Relatively soft material with good wear resistance: suitable for high sliding speeds.

Cu Sn 12 Ni DIN 1705

Relatively soft material with very high wear resistance: suitable for very high sliding speeds.

CuAl10Fe3 Mn2 DIN 17665 / 17672

Relatively hard anti-friction material, suitable for high loads and relatively low speeds.

Titanium alloy turbine gears

The main characteristics of titanium alloy turbine gears are low density, high strength and corrosion resistance, but the manufacturing process and cost are relatively complex.

In short, the material selection of turbine gears needs to be selected according to the specific conditions of use and requirements. Various materials have their advantages and disadvantages. Choosing the right material can effectively improve the efficiency and stability of mechanical transmission.
