Optibelt Red Power II Advantages

Thursday, November 11th, 2010

Wrapped Wedge Belts, Kraftbands and Pulleys

Advantage 1

Maintenance Free

 New production methods and new raw materials enable them for the first time to manufacture a wrapped wedge belt with requires absolutely no maintenance and which is of such low stretch that an Optibelt RED POWER II wedge belt correctly pretensioned once, does  any further retensioning.  As far as initial fitting of the Optibelt RED POWER II wedge belt is concerned, the same calculation methods and pretension values apply as for Optibelt standard wedge belts.
Advantage 2

Strong Power Rating

 The power ratings of Optibelt RED POWER II speak for themselves.  Compared to present day wrapped wedge belts, they are extremely high depending on section and pulley diameter.  In many cases, the performance level reaches the values of raw edge, molded cogged wedge belts.  Drive efficiency is as high as 97%.  Optibelt RED PWER II are oil, heat and dust resistant as standard. Heat resistance is also compared to raw edge V-belts but heading a smoother running belt drive.
Advantage 3

Cost Savings

 A special advantage of the Optibelt RED POWER II is the fact that real money can be saved.  Based on its high power ratings, fewer belts per drive are to be used!  With other words:  fewer belts,   and less space required.  Therefore:  lower costs and higher power rating.What an argument!By the way:  Optibelt RED POWER II is also available as a kraftband
Advantage 4

SetConstant

 Naturally, S=C PLUS applies to Optibelt RED POWER II, too.  Because of the fact that it is insensitive towards performance shocks, the “new one” runs especially well in sets, proverbial smooth running.  The tolerances of Optibelt RED POWER II are substantially lower than the set tolerances fixed by industry standards.
Advantage 5

Environmentally Friendly

 Contrary to many other transmission belts, there is virtually no material waste during the production of the se3rvice free wrapped wedge belt Optibelt RED POWER II.  We can proudly say that we achieved the goal of producing the most environmentally friendly transmission belt.

Construction of Optibelt V-Belts

Thursday, August 19th, 2010
    

Base Rubber     

The base rubber for Optibelt V-Belts is extruded in long lengths from a specially prepared rubber mixture.  This extrusion has a very high cross-sectional accuracy and also creates uniformity of belt weight per unit  length.  Uniformity of density throughout a V-Belt is of prime importance for vibration free running.     

 Tension Cord     

The tension cord for Optibelt V-Belts is manufactured from polyester fiber spun into various thread configurations. The physical properties of a tension cord are matched to the nature of the belt application and are dependant upon the configuration into which the cord is spun. To ensure that the tension cord has good adhesion within the V-Belt, it is specially impregnated so that it is fully compatible with rubber, and then sprayed. A completely homogeneous bond with the base and filler rubber is therefore guaranteed.     

 External Cover Fabric     

The cover consists mainly of a cotton fabric which has a highly twisted, shear resistant, warp and weft fibers.  Broad widths of the fabric are treated on both sides with a neoprene natural rubber mixture, and then cut into diagonal strips; the width being determined by the section of the V-Belt to be covered.  

Manufacture

Optibelt V-Belts are manufactured on highly automated machines.  Every V-Belt is constructed individually.  A measured length of tension cord having an exact number of turns is guided over two rolls, together with the filler rubber.  The accurately extruded base rubber.  The pre-prepared strip of cover fabric is finally wrapped around the V-Belt.  The semi-finished V-Belt is now ready for vulcanization.  

The ORV Vulcanization Process

The ORV (Optibelt Rotary-Vulcanization) process, which was developed by them, differs quite considerably from the traditional methods of vulcanization.  In the ORV process, V-Belts are vulcanized in heated V-Grooves while rotation takes place, hence in the same mode of motion and shape in which they will subsequently give service. 

With the traditional methods of vulcanization it is very difficult to exercise any control over the retention of the nominal lengths of the belts, whereas by means of their electronically controlled cord stabilization process, which they have patented in many countries, the nominal length tolerances of V-Belts vulcanized by the ORV process are restricted to a minimum. 

A “Panzerband”, which revolves around guide rollers and is tensioned by means of a hydraulically operated tension drum, presses the V-Belts into the V-grooves of the heated vulcanizing drum.  The V-Belt flanks and the sides of the pulley grooves, without significant distortion.

Cord Stabilization

Electronically controlled cord stabilization during manufacture gives Optibelt V-Belts their unique SetConstant feature.

Optibelt SetConstant V-Belts of similar nominal length can be assembled into matched sets at random without further measurement.  Length stability is guaranteed over many years, even under adverse storage conditions.

Bearings Incorporated is proud to state that we have been a faithful distributor of Optibelt quality belts for many years now.
