Split sprockets come into their own when the engineering time taken to remove sprockets involves the dismantling of large parts of the drive or when multiple sprockets are fitted on the same shaft. When it comes to conveyor chain sprockets which are often large and heavy this may require the use of a crane to get the sprocket into place. All these issues can lead to increased downtime.
Many manufacturers produce this type of product by splitting an existing sprocket and then joining the two sections together again. For the engineer this often results in a poorly assembled component leading to uneven loading in operation and increased wear to the sprocket teeth, bore and keyways. As a result many maintenance managers are reluctant to fit them.
At FB we have a different solution. We manufacture the high quality sprockets as two separate segments. The two mating sections align perfectly ensuring long and trouble free operation.
FB spit sprockets are manufactured from special grade alloy steels. The tooth profiles are CNC machined for close engagement, or flame cut and benefit from localized induction hardening in order for the sprockets to cope with the demanding environments. Unlike off the shelf sprockets, through discussions with customers FB can also add design solutions such as special dirt clearance grooves at the base of each tooth profile to ensure there is little or no build-up of the conveyed material. This type of sprocket design is advantageous in many high wear industry applications such as cement and recycling.
