Varvel RD Range
The series RD helical gearboxes feature a one-piece cast housing complete with inner support to acommodate 2 or 3 gear stages into the same casting. Manufactured to the latest ISO engineering design specifications, the housing is checked by computer aided structural analysis for deflection and stress distribution.
Significant strains caused by the effects of torque and external loads do not deflect the monolithic ribwork of the housing, which significantly improves the intergrity of the sealed surfaces.
The series RD helical gearboxes are manufactured in B3 base mounted configuration. They can be easily converted to B5 flange mounted by fitting of the appropriate additional adaptor flange.
Single setup machining on state of the art CNC production lines, the most recent calculation tequniques and process control gives superior operational reliability, maximum output torques, high overhung and thrust load capacity and long working life times.
The series RD are made up in 7 sizes and output torques of 20Nm to 2500Nm are available.
