Power transmission belts
Extremultus high-efficiency flat belts are
characterized by their long service lives, highly uniform RPM speeds,
high effectiveness > 98% and good damping properties.
Several shafts can
be driven simultaneously in the same and opposite directions.
Furthermore, Extremultus power transmission belts can be turned at an
angle to the axis of the running direction (mule drive) and are also
suitable for use on conical pulleys (taper-cone drive).
Extremultus P line
Extremultus high-efficiency flat belts of the P line
are available with friction coatings/coverings of highly wear-resistant
elastomer G or chrome-tanned leather on both sides. The polyamide
tension member is characterized by its good elastic property/ behaviour,
which dampens impacts and oscillations.
The elastomer G friction coating is used for all
standard drives in carding machines, drawing frames, fan and main drive
belts for spinning frames and twister operating under dry or dusty
conditions.
The chrome leather L friction coating is used for all
standard drives in carding machines, drawing frames, flyer spinning
frames and for main and secondary drive belts in twister and texturing
machines, especially where oil and grease factors play a role. On
taper-cone drives the belt can be shifted easily thanks to its
particularly stiff edges and the good sliding and wear properties of the
chrome leather friction covering.
Extremultus E line
Extremultus high-efficiency flat belts of the
innovative E line have highly wear-resistant friction coatings of
elastomer G on both faces and are well suited for use on either simple
two-pulley drives or multiple-pulley drives. Various polyester tension
members and a large operational elongation range of 1.0 � 2.5% make
individual power transmission possible by appropriate selection of
elongation at fitting.
The flexible belt construction makes the Extremultus
E line a universal drive belt, in particular for mule or torsional
drives and for applications with small pulley diameters. The symmetrical
belt design and the smooth Z-splice ensure exact belt tracking with
minimal angular velocity oscillation.
The thermoplastic, flexible tension member helps save
energy and is also largely unaffected by fluctuations in ambient
conditions, ensuring no maintenance.
