Practical Calculations for Parallel Line Couplings

Formula 1: Torque Calculation

T=F×rT = F \times r

Where:

  • TT: Torque (Nm)
  • FF: Force applied (N)
  • rr: Distance from the axis (m)

Example 1: Verifying Torque Capacity

Task: A motor generates a force of 20 N at a radius of 0.02 m. What torque is required?

Solution:

T=F×rT = F \times r T=20N×0.02m=0.4NmT = 20 \, \text{N} \times 0.02 \, \text{m} = 0.4 \, \text{Nm}

Conclusion: The LT-B-D15L20, with a rated torque of 0.5 Nm, can handle this application comfortably.


Example 2: High-Speed Suitability

Task: Your system operates at 25,000 RPM. Can the LT-B-D19L25 coupling handle this speed?

Solution:
The maximum speed for the LT-B-D19L25 is 25,000 RPM, making it a suitable choice for this application.
