Technical calculations

■Life of Flanged Linear Bushings

When the linear system is loaded in linear reciprocating motion, scaly damages called flaking appear due to material fatigue as the repeated stress is applied on the rolling elements and the rolling contact surfaces constantly. Total travel distance until the first flaking occurs is called the life of linear system.

Rated life can be calculated with the basic dynamic load rating and the actual load applied on the linear bushings, as shown below.

  • L: Rated Life (km)
  • fH: Hardness Factor (See Fig.1)
  • fT: Temperature Factor (See Fig. 2)
  • fC: Contact Factor (See Table-3)
  • fW: Load Factor (See Table-4)
  • C: Basic Dynamic Load Rating (N)
  • P: Applied Load (N)

Hardness factor (fH)

For liner system applications, sufficient hardness is required for ball contact shafts. Inappropriate hardness causes less allowable load, resulting in shorter life.

Fig. 1. Hardness Factor

Temperature factor (fT)

When the temperature of linear system exceeds 100°C, the hardness of the system and shafts will be reduced and the allowable loads will also be reduced compared to being used at room temperature, resulting in a shorter life.

Fig. 2. Temperature Factor

Contact factor (fC)

More than two linear systems are used for one shaft in general. In this case, the load applied to each linear system varies depending on machining precision and is not uniformly distributed. As a result, allowable load per linear system changes depending on the number of linear systems used on one shaft.

Table-3. Contact Factor

Number of bearings installed on one shaft. Contact factor fC
1 1
2 0.81
3 0.72
4 0.66
5 0.61

Load Factor (fW)

To calculate load applied to the linear system, in addition to object weight, it requires inertia force attributed to motion velocity or moment loads. Further, it is necessary to accurately determine the temporal change of each. However, it is difficult to calculation the load accurately due to potential vibrations and shocks caused by other element than repeated start-stop motions during reciprocating motion. Therefore, use the table below in order to simplify the life calculations.

Conditions of Use fw
No shocks / vibrations,
low speed: 15m/min. or less
1.0~1.5
No significant shocks / vibrations,
medium speed: 60m/min. or less
1.5~2.0
With shocks / vibrations,
high speed: 60 m/min. or more
2.0~3.5

Life in hours can be obtained by calculating the travel distance per hour. When the stroke length and the number of strokes are constant, it can be calculated using the formula below.

  • Lh: Life (Hr.)
  • L: Rated Life (km)
  • Ls: Stroke length (m)
  • n1: Number of cycles per minute (cpm)

Application Overview

Purpose

  • A suction head is used to transfer thin plates.
  • To prevent damage to the workpieces, a spring is utilized to act as a cushioning function when the positioning accuracy of the hand is poor.

Points for use

  • Handle the workpiece using heads with suction pads after the workpiece has been set.
  • Applicable to relatively low frequency handling.

Target workpiece

  • Thin plate
  • Material: Glass epoxy
  • External dimension: 300 x 250 x 1
  • Workpiece weight: 135g

Design Specifications

Operating Conditions or Design Requirements

  • Cushion stroke of suction pad: 10mm
  • External dimension: W495 x D160 x H224

Required Performance

  • Positioning accuracy: 1mm increments

Selection Criteria for Main Components

  • Spring
    • Select a spring force that will avoid damaging the workpiece.

Design Evaluation

Verification of main components

  • Select a spring force sufficient to avoid damage to workpieces.
  • Spring
    • Conditional values: Force applied to workpiece=30N, Spring constant k=0.5N/mm, Spring deflection x=29mm
    • Calculation: Spring force when sucking workpiece. From F=kx, F=0.5×29=14.5 < 30N
      ⇒Workpiece will not be damaged due to spring force.

Other Design Consideration

  • In this example the speed and frequency is low, so a stripper bolt has been selected to reduce the cost. If the speed or frequency is high a linear shaft should be used instead.
