Hygienic Design planetary gearbox HLAE from Neugart

The highest standards for the food, pharmaceutical and cosmetics industries

With the HLAE, Neugart has developed a hygienic gearbox solution for use in the food, pharmaceutical and cosmetic industry. With the HLAE, Neugart has developed a hygienic gearbox solution for use in the food, pharmaceutical and cosmetic industry. It is the world's first planetary gearbox in Hygienic Design that also meets the strictest international hygiene.

The HLAE is characterized by having a round design with smooth surfaces, which do not allow dirt deposits and microorganisms to adhere to the gearbox. Electropolished stainless steel 1.4404 with a very high surface quality of Ra < 0.08 µm is used as the material. The flange surfaces of the gearbox are sealed using a special O-ring in such a way that no bacteria can be drawn into the gap by capillary action. Two food-compatible plastics with high hot water and steam resistance are available as sealing material.

Flexibility during installation

The hygiene-compatible HLAE is available in three sizes for ratios ranging from i=3 to i=100 and for nominal torques of 15 Nm to 170 Nm. This provides a high degree of flexibility: it can be attached to B5 and B14 motors in any installation position. A version of the output shaft with a feather key and a smooth version are optionally available. A freely positionable sealing kit provides maximum hygienic protection for different wall thicknesses. It therefore provides maximum flexibility when the gearbox is being attached to the machine.
