Classical Raw edge cogged V-Belts are also known as Cut edge Belts or simply Cut Belts. As the name signifies, the edges (sidewalls) are cut from sleeves and the sidewalls are not covered i.e. they are raw. There is no fabric wrapping on the sides as in the same of normal belts. Again Raw Edge Belts come in three basic designs. They are Raw Edge Plain (REP), Raw Edge Laminated (REL) and Raw Edge Cogged (REC). Raw Edge Plain belt has one or two fabric layers situated above the cable cord and the bottom edge might or might not have a single fabric layer. The efficiency of these belts has been so overwhelmingly attractive that these belts have started rapidly replacing other type of belts in the class of application for which they are suitable. The cogged underside of the Classical Raw Edge Cogged belts reduces bending resistance significantly, thereby enabling use of pulleys with even smaller diameters up to 20% less than for the same type of application. Further the decreased bending resistance reduces mechanical losses during bending. This means improved power transmission, lesser heat buildup and also reduced working temperature. Heat dissipation is expedited as the belt has a large surface area per unit length.

Properties

• Very high flexibility due to moulded cogs
• Excellent traverse rigidity because of EPDM Rubber based compound with an-isotropic fibre orientation
• Very low stretch due to use of length stable polyester cords.
• Higher power rating of upto 30% over wrapped V-Belts.
• Low Slip due to better arc of contact and pulley to belt geometrical relationship.
• Energy loss reduced to absolute minimum.
