Miniature Linear Guides Servo Motor Ball Screw Couplings <Prerequisites> Drive Motor: Servo Motor, Driven Side: Ball Screw Rotational Direction: Reverse Rotary, Rotational Speed: 3000rpm Lateral Misalignment: 0.1mm Angular Misalignment: 1° Axial Misalignment: 0.1mm Shaft Bore Dia. Motor Side: 14mm, Ball Screw Side: 15mm Coupling O.A.L.: 60mm or less 1. Select Coupling Type Required characteristics of coupling from the above conditions t Zero Backlash t Allow lateral/angular misalignments Refer to the above Coupling Easy Selection Chart, and select. Compatible Coupling Type Disc Couplings: GCPW 2. Calculate the compensation torque applied to coupling Condition: Servo Motor's Peak Torque: 3.0N t m Servo Motor's Rated Torque: 1.0N t m Calculation of Compensation Torque Compensation Torque = Motor's Peak Torque (3.0N t m) x Compensation Factor (2.0) = 6.0N t m Select D(O.D.) with allowable torque 6.0N t m or more GCPW39 * Compensation factor is for reference when using couplings with servo motors in general. Please use the values as reference. 3. Check coupling tolerance Allowable Lateral Misalignment: 0.25mm Allowable Angular Misalignment: 1° Allowable Axial Misalignment: ±0.5mm Allowable Rotational Speed: 10000rpm Conditions are met 4. Select shaft bore Check if 14mm and 15mm shaft bore can be selected in GCPW39. 14mm and 15mm both fall under the category of D (O.D.) = 39 specification. d1=14, d2=15 GCPW39-14-15 5. Selecting the method to fasten shaft bore GCPW has only clamp, and need not be selected 6.
