  • * 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.

Application Overview

Purpose

  • Assist visual inspection of workpiece carried over by conveyor. Rotary mechanism is driven by a motor stationed at the inspection point.

Target workpiece

  • Shape: plastic plate
  • Size: W 65 x D 8 x H 130 mm
  • Weight: 150 g

Design Specifications

Operating Conditions or Design Requirements

  • Rotational speed at inspection: 12 rpm
  • External size: φ 90 x H 80 mm

Required Performance

  • Position repeatability: ± 0.3 mm

Selection criteria for Main Components

  • Rotational speed of the workpiece: 12 rpm, O.D. of rotary pallet: φ 90 mm Select bearings with a size having a margin fitting this dimension.

Design Evaluation

Verification of main components

  • Verify bearing durability for the load condition.
  • Check the life of bearing
    • Conditional values: bearings:
      Basic dynamic load rating of C6903ZZ: Cr = 4.65 kN = 4650 N,
    • Workpiece weight: M1 = 150 g = 0.15 kg,
    • Component weight borne by the bearing of the rotary pallet: M2 = 400 g = 0.4 kg,
    • Gravitational acceleration = 9.8 m/s².
    • Let radial dynamic equivalent load be Pr, radial load Fr, thrust load Fa, radial factor X = 1, and thrust factor Y = 2.3 , then,
    • Only the thrust load will be applied to the bearing by the workpiece and component. Assuming that radial load Fr = 0 N, We obtain the following: Fa = (M1 + M2) × g = (0.15 + 0.4) × 9.8 = 5.4 N,
    • Pr=X×Fr+Y×Fa=1×0+2.3×5.4=12.4[N].
    • Rated life (10⁶ rotations): L = (Cr/Pr)³ = (4650/12.4)³ = 52.7×10⁶ (10⁶ rotations) = 52.7 (10¹² rotations) Thus, there exists sufficient margin.

Other Design Consideration

  • Be careful during the inspection process as the workpiece may fall off the grip. Therefore, implement additional workpiece securing mechanisms as necessary.
