A helical bevel gearbox package from NORD Drivesystems was installed at a leading New Zealand-based meat processing plant that sought to reduce downtime and running costs within their facility.
The Alliance Group decided to upgrade their carton conveyors located at their Dannevirke, Hawkes Bay meat processing plant. Seeking to upgrade to modern, reliable and more efficient technologies for their conveyor systems, Alliance turned to their power transmission supplier, Russet Engineering Supplies to recommend and supply an advanced geared motor drive package. The new solution also needed to address the issue of overheating in the existing worm geared motors even in the cold ambient temperature of 7°C inside the boning room, resulting in a very short service life of up to six months.
Alliance engineer Dennis Rodgers wanted the new geared motor package to offer increased reliability, and an extended service life in addition to the ability to withstand their aggressive washdown environment.
Russet Engineering Supplies turned to major gear manufacturer NORD Drivesystems, who in turn recommended the new NORD 2 stage helical bevel gearbox complete with the new NORD HM series smooth exterior electric motor.
Feature highlights of the NORD 2 stage helical bevel gearbox include an industry leading design incorporating oversized bearings to deliver high overhung output shaft load capacity, extending the reliability and service life of the geared motor; 97% efficiency enhancing the drive package’s capacity to transmit maximum torque with minimum demand to electric motor power; and high material specification, high tolerance manufacture, and heat treatments ensuring market-leading lifespan.
The new NORD HM series electric motors feature a smooth exterior surface with no cooling fins. Features also include all exterior surfaces sloped to facilitate flow of water and wash down off the surface; MEPS2 compliance (AS/NZS1359.5); and rated for S1 continuous duty.
A major advantage of the NORD geared motor assembly solution was that the entire package was coated with NORD’s Severe Duty Extreme Stainless Steel coating system (NSD), recommended for hygienic and food applications including washdown with aggressive chemicals. Formulated to set extremely hard, the NSD coating offers particular resistance to aggressive cleaning chemicals such as Sulphuric Acid, Hydrochloric Acid, and Caustic Soda, making it ideal for the meat processing industry.
NORD’s two-year factory warranty was an additional factor that influenced Alliance’s buying decision.
