Upgraded Mixer Gears Deliver Quieter Operation
Neptune Mixer Company, a manufacturer of portable industrial mixers and a division of the Neptune™ Chemical Pump Co., has made a commitment to providing mixers that offer the longest service life when compared to competitive brands. This longevity is designed into the product through the use of steel helical gears, high-quality bearings and high-grade lubricant. Recent feedback from customers highlighted an opportunity for Neptune to reduce the perceived sound levels being emitted from the gear-train on several of its mixer lines. Specifically, this was an occurrence during the early stage of the mixer’s product life when it was still in the “break-in” period. With that valuable feedback in mind, Neptune worked closely with its gear supplier to optimize the gear-tooth profile by increasing the American Gear Manufacturers Association (AGMA) Quality Class from a level 6 to a level 9, resulting in tighter manufacturing tolerances on the mesh and backlash and an improved running-surface finish. This upgraded, quieter gear operation was incorporated on Neptune mixers that went to market in September 2011.
