Motors: Stainless steel helical and helical bevel gear reducers

SEW-Eurodrive gives food processors an alternative to single worm gears.



SEW Eurodrive stainless steel bevel gear reducers
SEW-Eurodrive announces the RESF37 stainless steel helical gear reducer and KESA37 stainless steel helical bevel gear reducer. Helical and helical bevel gearing units reportedly use less energy, run cooler and last longer than typical single-worm gear units. The material, design and smooth finish are designed to deliver high resistance to bacteria, chemicals and processes common to the food processing industry.

Traditional single-worm reducers commonly found on processing equipment can be inefficient and can wear over time. Helical bevel gears have "an infinite life," according to an SEW Eurodrive spokesman, and are 50% more efficient than single worm gears. Also, "while the new stainless steel speed reducers are new on the outside, inside users will find the same high-quality gearing the industry has relied on for decades," according to the spokesman.

The shaft-mounted gear units are available with TorqLOC, the company's compact keyless hollow shaft mounting system. TorqLOC combines interchangeable bronze bushings and a stainless steel clamping ring for mounting onto various sized solid shafts. This eliminates the need for high tolerance machining of the shaft, and ensures the reducer can be easily removed even after years of service in the harshest environments.

The RESF37 and KESA37 are available with NEMA C-face motor adapters, IEC adapters or as gearmotors. Other options include seals to provide IP69K protection and food grade oil. All shafts and hardware are high quality stainless steel as standard. Units are available with ratios up to 134.82 and 106.38:1 respectively. Both have an input power rating of up to 3 HP and an output torque rating of 1,770 lb-in.

Separately, SEW-Eurodrive offers a free, on-demand webinar, " The Truth About Energy-Efficient Motors ." Do energy-efficient motors really provide the energy savings everyone anticipates? Find out about research that shows that drivetrain efficiency is just as important as motor efficiency.
