The helical gearboxes Series RD feature a one-piece cast housing complete with inner support to accommodate 2 or 3 gear stages into the same casing. Manufactured to 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 hous- ing, which significantly improves the integrity of the sealed surfaces.
The helical gearboxes Series RD are manufactured in B3 base mounted configuration. They can be easily converted to B5 flange mounting by fitting of the appropriate additional adaptor flange.
Single-setup machining on state-of-the-art CNC production lines, the most recent calculation techniques and process controls give superior operational reliability, maximum output torques, high overhung and thrust load capacity, and long working life-time.
IEC or NEMA motor are easily mounted by fitting interchangeable bolted flanges and elastic couplings.
The elastic coupling, built-in inside the gearbox body, does not affect any dimensional length increase of the gearbox.
Range: 7 sizes; housings and covers of aluminium die cast up to size 4, of cast iron from size 5; two- and three-gear trains.
