    This data is utilized in order to list more useful application examples in the future.

    Cautions on the CAD data

    1. Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
      You will need to edit the Data so that it meets your specific design conditions.
    2. The CAD data unit assembly consists of sub-assemblies.
      Each sub-assembly unit can be used as it is or can be edited.
    3. * The part in the frame is a sub-assembly unit.

    4. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    5. The Data including the third-part components are made by the Company.

    Back to top

  • * Unit assembly CAD data consists of some sub-assemblies.
       Each sub-assembly unit can be used as it is or can be edited.

Application Overview

Purpose

  • Fixture to measure aging variations (dimensional changes over time, and cracking, etc.) by applying repeated loads. (Not to the extent of destruction)

Points for use

  • Motor driven oscillating mechanism.

Target workpiece

  • Levered lug
    External Dims.: W40 x D30 x H3 (excluding the lever)
    Workpiece weight: 5g

Design Specifications

Operating Conditions or Design Requirements

  • Oscillates in ±45° range.
  • External dims.: W516 x D300 x H468

Required Performance

  • Tensile load: 60N
    Spring constant: 4.13N/mm

Selection Criteria for Main Components

  • Motor
    • A motor is selected for automated oscillating motion.
  • Spring
    • Spring selection makes applying arbitrary loadings possible.

Design Evaluation

Verification of main components

  • Select an appropriate motor for oscillating motion.
  •  Motor speed
    • Motor RPM (Ns) : 1800rpm
    • Reduction ratio (i) : 1 / 50
    • Rotation pitch circle diameter (Dp) : 156mm
    • Link ratio: Approx. 1 / 3
    • Speed (V)
      V = Ns x (1 / 60) x i x π x Dp x 1 / 3
        = 1800 x (1 / 60) x (1 / 50) x π x 156 x 1 / 3 = 98mm/s
  • Torque
    • Motor torque Tm = 3.33N・m
    • Assumed load: F = 60N
    • Link ratio: Approx. 1 / 3
    • Fa = F * 1 / 3 
    • Load torque TL = (Fa x Dp) / (2 x 1000) = 60 x (1 / 3) x 156 / (2 x 1000) = 1.56N・m
      Tm > TL, OK.
  • Spring load
    • Formula: Reaction force F = kx
    • Assumed load: F = 60N
    • Deflection under tension: x = 14.5mm
    • Spring constant: k = 60 / 14.5 = 4.13N/mm selected

Other Design Consideration

  • The spring load can be varied by moving the spring post in a slot located on the plate. An adjusting bolt is used for adjustments. The above configuration makes it easy to change the spring (varying the tension)
