Rulmeca Moving ahead. GENERAL STANDARDS Steel ^ 0.03 The elements that determine the initial design of a roller conveyor are: - The dimensions of the packages to be conveyed (x-y). - The condition of the support base of the packages in contact with the rollers. - The weight and number of packages to be conveyed for each sector driven by the single Drive Roller. - The transfer speed. Roller pitch (or distance between rollers). For efficient transfer of the packages on a roller conveyor it is good practice for the packages to have a sufficiently rigid and flat contact surface (so-called “rollable”)...

Rulmeca Moving ahead. PRESCRIBED USE AND DESIGN CRITERIA Each type of roller proposed by Rulmeca is characterized by a nominal capacity value. Refer to the roller section or to the “Rollers for internal conveying” catalogue. It is defined as: P1 = Nominal load pressing down on a roller [daN] Pc = Load capacity of a roller or capacity [daN] Pr = Weight of the rotating parts of a roller [daN] Pt = Total weight of a roller [daN] Pu = Weight of a package [daN] n = Number of rollers The camber values of loads of the same weight increase or decrease according to how the load is distributed. In general,...

Rulmeca Moving ahead. CHOOSING YOUR DRIVE ROLLER The conveyed material moves perpendicularly to the axis of the roller, so when calculating the necessary forces, the revolving friction of the roller with the surface of the base of the conveyed package must be taken into account. Apply this formula to define the tangential force necessary for handling the package: Ft = P x G x U where: Ft) required tangential force [N] P) Weight of the package (kg). G) Gravity acceleration = 9.81 [m/s²] U) Friction coefficient. Once the tangential force that is necessary to move the package has been determined,...

PRESCRIBED USE AND DESIGN CRITERIA Rulmeca Moving ahead. MOTION TRANSMISSION Transmitting motion from drive roller to neighbouring rollers A conveyor with controlled rollers can be built using Drive Rollers with grooves or pulleys connected to idler rollers using the same motion transmission system (driven rollers). Belt transmission To connect the drive roller to the idler roller with grooves or pulleys, use round polyurethane belts (easily available on the market). The extent and pretensioning of the round belts depend on the conveyed load and on the roller pitch specified in the design phase. Generally,...

Rulmeca Moving ahead. POLY-V BELTS TABLE FLEXIBLE 2 AND 3 RIB POLY-V BELTS, PITCH 2.34 - PROFILE J ISO 9982 DIN 7867 Warning The order code does not give the roller pitch. For permitted roller pitches, see the relevant column. Warning The printed reference number on the belt (PJ-XXX) is not the belt extent and must not be used to calculate roller pitch. The original winding diameter of the belt is calculated as 1 mm above the pulley: Dp = 0 pulley + 2 mm. Recommended average tension 5%. Min/max permitted tension range 4-6%.

Rulmeca Moving ahead. THE RDR DRIVE ROLLER The Drive Roller can support both a load acting directly on it (a portion of the weight of the package pressing down on the Drive Roller and/or the load due to the tension of the conveyor belt), and convey loads distributed on the roller conveyor portion driven by the Drive Roller. Load capacity The load capacity (Pc) on the individual Drive Roller is 35 daN. Conveyable loads The total load that can be conveyed by the rollers driven by a single Drive Roller can be extrapolated from the torque/tangential force supplied by the motor with the different...
