Fits all: The 60-mm-square shaft on the drive fits industry-wide standard belt-drive sprockets.
By re-engineering a belt-drive design, Interroll engineers eliminated the need to heavily customize a drive to fit and retrofit modular, easy-to-clean plastic belt applications seeing increased use in the food industry.
By simply providing a 60-mm-square solid, stainless steel shaft extension on the pulley of the 138EMB belt drive, it can accommodate any standard modular, square-bore belt sprockets a customer is using without tools or modifications. Any number of sprockets can be slipped over the shaft as the user prefers for belt support. Only two floating sprockets (similar to those desired by the user) on the circular shell surrounding the motor and gearbox need be bored and fitted by Interroll. Spacing of this sprocket pair is adjustable along the bar of a special clamp that allows aligning the sprocket teeth.
Deflection of the shaft over long lengths (it can be used in rollers from 450 to 1,200 mm) led to using a solid, not hollow, bar, according to Product Manager Steve Hankey.
The design meets IP66/67 standards and currently delivers up to 0.5 hp. Power comes from a 230/460V, 60-Hz, 3-phase ac motor with a standard cable or terminal box connection.
