Worm Gearboxes (VF-Worm Gear)
The VF series includes gearboxes and gearmotors in which motion is transmitted through a pair of worm shafts and gears.
The key features of this product include:
֍ Relative non-reversibility under specified conditions.
֍ Smooth operation due to precise machining processes.
֍ Heat treatment and grinding of the worm shaft tooth profiles to increase efficiency, reduce noise, and minimize product defects.
֍ To extend gearbox service life, the worm wheel is made of high-strength aluminum bronze in compliance with ANSI/AGMA 6034-B92 standards.
֍ Adjustable installation positions and base orientations for simplified installation and commissioning.
֍ Cooling fan on VF 210 and VF 250 models to reduce heat, enhance efficiency, and extend gearbox service life.

Worm Gearboxes (VFU-Worm Gear)
VFU series gearboxes are a type of worm gearbox featuring an integrated base and housing.
The main features of this product compared to the VF series include:
֍ Ability to be installed in various orientations without requiring structural modifications; the integrated housing and base prevent oil leakage and premature failure of gearbox mounts.
֍ Exceptional resistance to breakage under adverse conditions.
֍ Increase in output torque (M2 daNm) by approximately 10 to 20 percent.
֍ Extended service life and enhanced visual appearance of the product.
The main applications of this product include:
֍ Relative non-reversibility under specified conditions.
֍ Smooth operation due to precision machining.
Worm Gearboxes (VF/VF-Worm Gear)
To achieve higher reduction ratios, two VF-type worm gearboxes are flange-mounted together. The ability to change the relative installation positions of the gearboxes provides access to a wide range of operating configurations. For attaining very low output speeds, it is recommended to use double worm combination gearboxes, through which higher torque can also be achieved in accordance with the relationship Ms₂ = Ma, Fs·Fs < Ms₂.
