April 15, 2014 - NORD Drivesystems announces Helical-Bevel gearboxes. The two stage helical-bevel design, referred to as the 92.1 and 93.1 series, offers high-performance, up to 97% efficiency and a 60% increase in torque to weight ratio over the previous series. Both series are available in five gear case sizes and are characterized by an open, smooth, self-draining outer surface.
The high-strength aluminum alloy housing 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. With a leak-free design, longer gear and bearing life, quiet operation and high output torque capabilities, the customer benefits from high efficiency, low maintenance and a long service life. Providing exceptional modularity and adaptability for all mounting positions, numerous possibilities exist for input, output and motor options. Input and output options are stocked at the factory to guarantee quick-shipment upon order. Available with either a NEMA or IEC input, a NORD motor or brake motor, the 92.1 and 93.1 are well suited for applications in the conveyor industry, material handling, car wash, and the food & beverage industry, including wash down environments. 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. An optional B5 mount is available. The 92.1 series is cost effective when compared to the 93.1 and is ideal for cooling, due to its large surface area.
- Universal foot and flange-mount housings
- Easy wash-down solution
- Cost effective design
- Foot, face (B14) and shaft mount
- External surfaces connected with large radius and generous mold release slopes provide for a cleanable, drainable housing
The 93.1 series is characterized by the closed design and comes as shaft and flange mount (B14) as standard. Optional drilled and tapped holes can be provided for foot mount requirements. In addition, an optional through-bolt, B5-flange is readily available. Because there are no cavities to this design, NSD tupH surface conversion system is available.
- Closed gearbox design
- No hidden chambers (cavities) for material build-up
- Optimal for NSD tupH Surface Conversion System
Optimized For the Food Industry The 93.1 Series is optimized for the food industry because of the lightweight, aluminum housing incorporating the newest technology. Designed and manufactured with inclined surfaces guarantee the draining of cleaning liquid in all mounting positions. By adding NORD's NSD TupH surface conversion system, washdown liquids always run off. The benefits of NSD TupH include no peeling, flaking or blistering of paint by providing a higher level of corrosion resistance. The 93.1 series is much lighter and offers better thermal conductivity than stainless steel. The design is optimized for use in the food and beverage industry and complies with international guidelines and standards such as EHEDG, ANSI, and ANSI / NSF. For sealing lubricants inside and keeping contaminants outside the reducer, NORD's four component QUADRILIP sealing system, is standard for both hollow and solid shaft unit types.
