Drive flange

Flange is generally understood to be a component for connecting, sealing and closing machine parts, housings with nuts and/or screws. This can be easily loosened and reused without having to be destroyed. In most cases, the corresponding operating forces are also transmitted. Machine flanges serve as bushings and these usually have a shaft. However, there are also designs that serve purely as mounting flanges without a passage. Drive flanges are machined on the surface with rolling tools. This protects the component from damage. Drive flanges are available in different designs.

What are flanges and driving flanges used for in particular?

Drive flanges are connections between the gearbox and the motor. In wind turbines, drive flanges are used to fix the rotor blades. In steel towers, they ensure the connection of the different segments. They are also used to fix bearings in housings and on shafts. Flanges are available for all-wheel drive as well as front-wheel and rear-wheel drive. Drive flanges are used for both front and rear axles.

Types of Drive Flanges

The most common types are powder coated steel. The most common application is motors. A gearmotor consists of a gearbox and the motor. The outer drive shaft moves at a lower speed, but with a greater torque than the inner motor shaft. Motor and gearbox form a unit in vehicles and are usually located in a common housing.

Electric motors have the same rated power, but operate at a higher speed. Therefore, a reducing gear is used here. Internal combustion engines work in a similar way. Geared motors are equipped with a standardized flange. With this they can be connected to the shaft to be driven via a coupling lantern with a housing to be connected. This can also be done via a metal bellows coupling or a corrugated tube coupling.

A drive flange half round with cast-on brake disc has a twist-free ground, inductively hardened sealing ring running surface and external and internal toothing. The blank surfaces are usually primed. The connection designs can be different (cross toothing according to DIN 8667, half round, wing style). The material in this case is often cast iron.

What else should be considered?

Drive flanges are increasingly being manufactured according to customer-specific drawings. The most important factors here are accuracy of fit, high-quality materials and workmanship. Of course, the type of vehicle, drive, etc. also plays an important role. Manufacturers should therefore produce drive flanges for different vehicles. Drive flanges are not only required for passenger cars and trucks, but also for agricultural vehicles, fire brigade vehicles, recovery vehicles, snow groomers, etc. Drive flanges are in continuous use. They must be resistant and robust. Especially for emergency vehicles, spare parts must be available at all times. Slightly damaged flanges should be replaced immediately.
