>> GFC ANTRIEBSS YS T EME For more than 100 years, the name GFC stands for high precision, engineering ingenuity and customised solutions in producing worm gear units and drive systems. Lean hierarchies and short decision-making allow a exible and quick reaction to customer requirements. We offer long-lasting solutions and reliable system components in top material quality for machines and systems in virtually any size. Gears from our modular construction system can be modied and completed with the option of silenced brake motors, adjustable mechanisms, electronic speed controls or...

our development department and also due to our staff‘s ongoing training programmes. It goes without saying that certications in compliance with EN ISO 9001 and EN ISO 14001, DNV and ABS have been signicant quality parameters and form a standard for the GFC production. Our highly qualied eld service and technical trained personnel as well as their in-depth consulting knowledge allow GFC to provide creative solutions to any drive technology task. We are ready for a challenge! >> Our product range includes: Worm gear units/motors – Centre distance a = 40 – 500 Helical worm gear units/motors –...

Specications for enquiries >> If the gearbox is to be exactly sized by GFC, we then request from you the following specications: 17. Transmission of power from the actuator machine to the gearbox 18. a) Temporarily high torque levels b) Additional forces to be absorbed by the bearing of the transmission (in N) and their direction, resulting from any additional loads on the shaft ends by gears for belts, V-belts, chain gearboxes of gears of any type 19. Device description (series, operation position) of the transmission (see Device Description Overview) 20. Are any particular properties...

the operating efciency rating ≤ 0.5. This takes effect in worm gearboxes (according to the prevailing surface quality and toothbearing size at centre-increase angles ranging from = 2.5° to 4°. Self-locking worm gearboxes are inefcient due to their poor overall efciency rating and the correspondingly high loss of output (particularly considering the extensive installation space and long power-on times). In those actuator situations in which the self-locking effect is required, one should always verify whether the installation of a return block or a brake is the more practical solution. A...

□ Selection of gearbox sizes The selection of the gearbox size is based on the greater of the two calculated values. Here, the following applies: T2N = nominal torque of the transmission on the slow-running shaft. □ For gearbox motors, the total operation factor The total operation factor calculated for each individual case of operation may not exceed the permissible output factor fv. For all gearbox motors, the permissible output factor fv is indicated in the output speed output overviews. At ambient temperatures of < -150 C, please consult us before taking further action. Agitators for...

>> MODUL AR UNIT S AND SPECIAL SOLU TIONS GFC worm gear sets consist of case-hardened and ground worm shafts combined with worm wheels made of high-quality, wear-resistant centrifugally cast or continuous cast bronze. Worm gear sets are characterised by shock-resistant, vibration-absorbing and low-noise gear teeth and provide large transmission ratios within a single stage. Self-locking at standstill is possible. We produce worm gear sets in standardised type ranges or according to the specications of our customers. Sophisticated and individual solutions are provided by using modern and...
