Technical calculations

Operating Life Calculation for Linear Guides

Operating Life
When the linear system is in motion with applied load, the rolling surfaces and races are subject to repeated stress, This stress can cause scale-like flaking due to material fatigue. The total run distance until the flaking appears in the "Life" of the linear sytems.
Rated Life
Rated life is the total travel distance that 90% of linear guides of the same type can reach, under the same conditions, with no occurrence of flaking damage. Rated life can be calculated with the basic dynamic load rating and the actual load applied on the linear guides, as shown below.
Load must be calculated before actually using the linear guides. To obtain loads during linear reciprocating motion, it is necessary to fully consider vibrations and impacts during motion as well as distribution condition of the load applied to the linear guides. So, it is not easy to calculate the loads. Operating temperature also critically affects the life. Considering these conditions, the formula will be as follows.
  • L: Rated Life (Km)
  • fH: Hardness Factor (See Fig.1)
  • fT: Temperature Factor (See Fig.2)
  • fC: Contact Factor (See Table-1)
  • fW: Load Factor (See Table-2)
  • C: Basic Dynamic Load Rating (N)
  • P: Applied Load (N)
Hardness Factor (fH)

For linear applications, the blocks and rails must have sufficient hardness. If they do not, the load rating decreases and the life will be reduced.
Please correct the rated life with the hardness factor.

Temperature Factor (fT)

When the temperature of the linear system exceeds 100 degrees C, the hardness will decrease and as a result, the allowable load and life will reduced.
* Please use Linear Guides at within the heat resistance temperature ranges shown on product pages.

Contact Factor (fC)

Table-1. Contact Factor

Number of Blocks per Rail Contact Factor fC

1 1.00
2 0.81
3 0.72
4 0.66
5 0.61

In general, it is common to use two or more blocks on one rail. In these cases, the load on each block will vary depending on the machining precision and will not have equally distributed loads. As a result, the allowable load per block will vary depending on number of blocks used on the rail. PLease compensate the rated life with contact factors on Table-1.

Load Factor (fW)

Table-2. Load Factor

Condition 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
1.5-20
With shocks / vibrations,
high speed: 60m/min. or more
2.0-3.5

To calculate the load applied to the linear guides, in addition to the object weight, the inertia force attributed to the motion velocity, moment loads and the variations of each over time must be obtained. However, for reciprocating motion applications, it is difficult to obtain accurate calculations due to the effects of the vibrations and shocks. Therefor, use Table 2 to simplify the life calculations.

Applied Load P Calculation Method
When moment load is applied to each block, convert the moment load into applied load by the following formula.
  • P: Applied Load (N)
  • F: Downward Load (N)
  • Co: Static Load Rating (N)
  • MA: Allowable Static Moment - Pitching Direction (N·m)
  • MC: Allowable Static Moment - Rolling Direction (N·m)
  • Lp: Load Point Distance (m) in Pitching Direction
  • Lr: Load Point Distance (m) in Rolling Direction

Application Overview

Purpose

  • An ascending/descending mechanism that can turn to change the transfer direction. This mechanism uses an air cylinder and a rotary actuator.

Points for use

  • After loading a workpiece in the roller conveyor unit, the work guides ascend to hold the workpiece during turns.

  • Box shape: cardboard box
  • Size: W600 x D300 x H350mm
  • Mass: 1kg

Design Specifications

Operating Conditions or Design Requirements

    • Outer dimensions: W1109 (up to work guide) x D650 x H707 (not including roller conveyor, during ascending) [mm]
    • <Roller conveyor unit side>

 

    • Air cylinder stroke amount: 30mm
    • Rotary actuator oscillation angle: 90°
    • <Lifter unit side>

 

  • Air cylinder stroke amount: 250mm

Required Performance

  • Required load: 397.88N

Selection Criteria for Main Components

  • Cylinder
    • A cylinder with a guide is selected for holding the workpiece.
  • <Lifter unit side>
  • Cylinder
    • A compact cylinder is selected for space-saving purposes.

Design Evaluation

Verification of main components

  • Verify that the cylinder thrust can withstand the operating load.
  • Cylinder thrust
    • Conditional value: weight to move: workpiece (1kg) + rotary actuator (8.3kg) + conveyor unit (15kg) + lift base (16.8kg) = 40.6kg, operating air pressure: 0.5MPa, cylinder efficiency: 50% (assumption), theoretical output = 2268N (from catalog)
    • Load F = mg = 40.6 x 9.8 = 397.88N
    • Cylinder thrust on pulling side: theoretical output x cylinder efficiency = 2268 x 0.5 = 1134N
    • Safety factor: 1134/397.88 = 2.85

Other Design Consideration

  • The shock absorber absorbs the impact when the conveyor unit descends.
