Application example
Complete Freewheels BD 28 R as overrunning clutches in the roller conveyor of a continuous heating furnace system. The steel billets must run through the furnace at increasing speed. In
order to achieve this, overrunning clutches with sprockets on both sides are arranged on the
drive side of the transport rollers. The driven sprocket has in each case two teeth less than
the driving sprocket. Therefor the speed in creases from roller to roller. The length of the steel
billet covers several rollers, all running at differ - ent speeds. The freewheels allow the slower
rollers to adjust to the speed of the billet by overrunning their drive.
 
Mounting
The customer attachment part is centered on the diameter R and then bolted on to the face.
The pilot on the covers is particularly suitable for attaching smaller and narrower parts (sprockets, gear wheels etc.). The customer must provide fastening screws of the necessary length in order to mount the attachment part. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter R of the attachment part must be ISO H7 or J7.
