Conveyor drive head with return end

摘要

Two bearing points (46) in a plane parallel to the transport plane (15) in housing (11) serve upper guide rollers (32) and two bearing points serve two further bottom rollers in a plane lying between shaft (13) centre line and plane. Thus all the roller bearing points (46) are arranged in a plane (56) symmetric to the shaft centre line. The housing comprises top part and bottom part (60) to take the bearing points for the two sets of rollers respectively. The cover plate of the top housing half should have moulded recesses at its ends against the conveying direction which thus form supporting legs at the two housing ends, and the bearing seats for the rollers are moulded into these legs. The support plate has two vertical parallel bearing legs, each of these being recessed to bear on the drive shaft. The lower housing part comes in box form and the bottom roller bearings are moulded into the side pieces placed on the sides facing against the convey ing direction.
