■Calculation of Service Life of Ball Spline

Use the following formula for calculating the running service life of the ball spline.

• Radial Load

• Torque Load

  • L: Running Life (km).
  • ft: Temperature Factor.
  • fh: Hardness Factor.
  • fp: Ratio of Rated Load.
  • fw: Load Factor.
  • L0: Rated Life (50km).
  • C: Basic Dynamic Load Rating (N).
  • F: Applied Radial Load （N).
  • Ct: Basic Dynamic Torque (N·m).
  • T: Applied Torque (N·m).

Use the following formula for calculating the service life of the ball spline.

  • Lh: Run Time (hr).
  • L: Running Life (km).

    CAD Data Limitations

    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. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.

      3. * The part in the frame is a sub-assembly unit.

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

Application Overview

Purpose

  • Cleans work surface by blowing out dirt using air while the workpiece is being rotated.
    The workpiece is placed on a rotating table while the arm is lowered to clamp it down.

Target workpiece

  • Shape: Cylinder case
  • Size：φ85 x L 102 x t 5mm
  • Weight: 1kg

Design Specifications

Operating Conditions or Design Requirements

  • External dimensions: W 366 x D 482 x H 488mm
  • Arm swing angle: +/- 45°
  • Clam stroke: 50mm
  • Work rotation speed: 75rpm or more

Required Performance

  • Clamp section weight: 2kg

Selection Criteria for Main Components

  • Select a φ25 cylinder in order to lift clamp section 2kg.
  • Select motor of 40 W, reduction ratio 1/80 in order to rotate workpiece at 75rpm or more.

Design Evaluation

Verification of main components

  • Verifying permissible motor moment of inertia based on load inertia.
    • Checking load moment of inertia: J.
      Coupling moment of inertia:Jc=11×10 -5kg・㎡
      Set Collar moment of inertia: Js = mD²/8=0.095×(0.032)²/8=1.2×10-5kg・㎡
      Workpiece moment of inertia: JW = mD²/8=1×(0.085)²/8=90×10-5kg・㎡
      Rotating Shaft moment of inertia: J1 = mD²/8=0.9×(0.028)²/8=8.9×10-5kg・㎡
      Workpiece lower side holder section moment of inertia: J2=mD²/8=1.3×(0.085)²/8=120×10-5kg・㎡
      Workpiece upper side holder section moment of inertia: J3=mD²/8=2.1×(0.085)²/8=190×10-5kg・㎡
      Total: J = Jc + Js + JW + J1 + J2 + J3 = 421 x 10-5kg・m² < 3000 x 10-5kg・m2 = Permissible moment of inertia for motor: JM
      ⇒No problem

Other Design Consideration

  • The clamp arm is set to be capable of rotating 45° in order to avoid interference with the clamp while setting the workpiece.
