Helical cut planetary gear reducers – LPG
LEAX Detmold planetary gear reducers are suitable for sophisticated applications, such as being used as the drive system in calenders for the manufacture of transparent panels or optical film. The gears made of high-quality materials and featuring an optimised number of teeth and sensible modification of the profile, are produced in state-of-the-art manufacturing machines. They contribute to the minimal occurrence of surface disturbances and transverse markings. These gear reducers incorporate helical cut planetary stages and special gear ratios, which guarantee unmatched smoothness and an optimal transmission function. LPG gear reducers are available with free drive and output shafts as well as with motor lanterns for IEC or servo motors.
