92.1 Series 2-Stage Helical-Bevel Gearbox

July 28, 2014

The next generation of the premium efficient gearbox from NORD Drivesystems has been released for the North American market. The two-stage helical-bevel design, referred to as the 92.1 Series, offers high performance, up to 97% efficiency, and a 60% increase in torque to weight ratio over the previous series. The series is available in 5 gear case sizes and is characterized by an open, smooth, self-draining outer surface. The 92.1 Series, easily identified by its high-strength lightweight design, is a universal housing offering foot, face (B14), and shaft mount as standard.

 

Designed using FEM (Finite Element Modeling Technology), this high-strength aluminum alloy housing is manufactured using NORD's UNICASE Design. The UNICASE design consists of a one-piece housing where bores and mounting faces are machined in one step, producing precise tolerances that ensure accurate positioning of gear teeth, bearings, and seals. Internal reinforcements inside the gear case increase the strength and rigidity of the gearbox, resulting in a high-strength housing. This, in turn, provides for larger, high-capacity output bearings, increased overhung load capacity, and increased hollow bore capacity.
