Technical calculations

■Lead Screw and Lead Screw Nut Selection Steps

Calculate Contact Pressure P and Sliding Velocity V based on conditions of use to check that no abnormal wear will occur.
Plot the calculated P and V values against the PV value graph and confirm the intersection.
If the intersection falls inside of line (1) and (2), it is determined that abnormal wear would not occur

Determine Conditions of Use

Lead Screw and Lead Screw Nut Temporary Selection

(1) Contact surface pressure P, (2) Sliding speed V calculations
Verify that the value is within (1) and (2) of the PV value graph

Calculate Screw Efficiency η and Load Torque T

(axial load, rotational speed)

 

(lead screw and lead screw nut material)

(If not good)

    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.

    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.

Application Overview

Purpose

  • Motor drive is able to adjust the guides as needed.
  • Guide stays in sync because both left and right hand lead screws are used.

Points for use

  • The motor moves the guides to a specified width.

Target workpiece

  • Box
  • External dimensions: W150 ~ 300 x H150 x L400mm
  • Workpiece mass: 3 - 5kg

Design Specifications

Operating Conditions or Design Requirements

  • External Dimensions
    W500xH340xL1000mm
  • Guide dimensions
    H220xL1000xT9mm

Required Performance

  • Positioning precision: ±1mm unit

Selection Criteria for Main Components

  • Motor
    • Select a motor that can handle the weight of the guide.

Design Evaluation

Verification of main components

  • Verify allowable motor torque for meeting the required torque.
  • Motor
    • Conditional values: Guide weight W = 17 kg/piece, thread pitch P = 0.003m, thread efficiency η = 0.24, guide friction coefficient μ = 0.1, gravitational acceleration g = 9.8m/s², number of guides 2pieces
    • Required torque: T = W × g × μ × P/(2 × π × η) Thus, T = (17 × 2) × 9.8 × 0.1 × 0.003/(2 × π × 0.24) = 0.07(N・m) < 0.57(N・m) (60Hz)
    • Safety factor: 0.57/0.07 = 8.1

Other Design Consideration

  • An idler is installed at the middle point of the timing belt to adjust tension.
