Introduction FREESPANTM Belt is polyurethane timing belt made by MITSUBOSHI Belting Ltd. FREESPANTM Belt consists of thermoplastic polyurethane and steel cords. This belt is suitable for synchronous transportation and power transmission requiring accurate positioning. The tension members are parallel to each other to ensure a suitable synchronous drive. Polyurethane also has good physical properties & good chemical resistance. Belt Temperature range is from -30℃ to +80℃. Polyurethane ShoreA 92 Thermoplastic Polyurethane Tension member Zinc coated steel cords Steel Cord Mechanical...

Design Procedure STEP 1 Choice of Belt Tooth Profile Calculation of the Peripheral Force According to the Fig.-1, Select the tooth profile. This figure is based on more than 12 teeth meshing. In case of known Mass Horizontal or Conveying Fu=(m×α)+(m×g×μ) Vertical Fu=(m×α)+(m×g) Note μ number is shown in Table-5 In case of known drive power In case of known drive torque Determination of the Belt Width The belt width is calculated by following formula. Bw=(Fu×Ks×10)/(Fspec×Zm) Fu Ks Zm Zm Fspec Use above calculation result. Safety factor Number of tooth meshing in drive pulley....

Linear Motion Design Procedure (Example) Machine Condition Center Distance Pulley Diameter RPM Motor Power Fluctuating Rate Choice of Belt Tooth Profile Calculation of the Peripheral Force According to the belt profile selection table, We can choose AT10 Because Pulley diameter is 76mm, so Z=24 (O.D=74.54) Determination of the Belt Width Bw=(Fu×Ks×10)/(Fspec×Zm) Bw Bw Use above calculation result Safety factor Number of tooth meshing in drive pulley Z×arc　of　contact/360° Tooth share strength (N/cm) So, the next closest width is 25mm → 25AT10 is selected. Checking the Allowable Tension...

Calculation Parameters Belt Tooth Profile Selection This graph gives a indication of the belt width for each tooth profile. Please calculate the belt width followed by calculation procedure.

Safety Factor Safety factor depends on the operating conditions, Please use the following safety factor. Table-4 Operating Condition Safety Factor Steady Load Shock Load Coefficient of Friction When the supporting table is used, Please use the following Coefficient of Friction.
