Pulley for wire rope utilized in load moving system e.g. hoist, has support surface comprising mold for enlarging contact surface between pulley and rope, where mold is adapted to form of outer surface of wire rope

摘要

#CMT# #/CMT# The pulley (1) has a support surface (2) for guiding a wire rope (3) during running on the pulley and comprising a structured mold for enlarging a contact surface between the pulley and the wire rope, where the mold is adapted to the form of an outer surface of the wire rope. The mold comprises projections and/or recesses (4) formed in a rotating direction and/or in the direction of a rotational axis of the pulley. The support surface is formed by an edge section (6), and the mold comprises structure sections whose length is proportional to length of the wire rope. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for manufacturing a pulley (2) a device for manufacturing a pulley. #CMT#USE : #/CMT# Pulley for deflecting a wire rope utilized as a traction sheave in a load moving system (claimed) e.g. conveyor system, hoist and lift system. #CMT#ADVANTAGE : #/CMT# The support surface comprises the structured mold for enlarging the contact surface between the pulley and the wire rope, and the mold is adapted to the form of the outer surface of the wire rope, thus preventing high loading pressure leading to wear of the pulley and the wire rope, and hence increasing service life of the pulley and wire rope, and improving force transmission ratio during usage of the pulley as the traction sheave. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a portion of a pulley. 1 : Pulley 2 : Support surface 3 : Wire rope 4 : Recesses 6 : Edge section.
