| 1. The L10 expected life of a roller screw linear actuator is expressed as the linear travel distance that 90% of properly maintained roller screws manufactured are expected to meet or exceed. For higher than 90% reliability, the result should be multiplied by the followinig factors: 95% x 0.62; 96% x 0.53; 97% x 0.44; 98% x 0.33; 99% x 0.21. This is not a guarantee and these values should be used for estimation purposes only. The formula that defines this value is: Travel Life in millions of mm, where: C = dynamic load rating (N); F = cubic mean applied load (N); S = Roller screw's lead. L10 = (C/F)3 x S = | |||||||
| 2. Acme screw life expectancy: As a result of the high friction inherent to acme screws, life expectancy is unpredictable. Load, duty cycle, speed, temp, and lubrication all affect the amount of heat generated and thread wear by the acme nut which ultimately determines the life of the mechanism. Acme screws typically have lower life expectancies than roller screws and should only be used in low duty cycle applications. | |||||||
| 3. P x V for ACME screws should be kept below 0.1 P = Force/Max Force; V = Speed/max Speed |
|||||||
| 4. Input torque should be limited such that max force is not exceeded. For a parallel belt ratio, the input torque ratings must be divided by the belt ratio for allowable motor torque. The output force ratings remain the same. | |||||||
