IDEA NOTE Idea on the O-ring groove

Since the O-ring is used as a resistant body, the groove on the fastening side has a rectangular shape and the groove on the loosening side is V shaped.

    Cautions on the CAD data

    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. The CAD data unit assembly consists of sub-assemblies.
      Each sub-assembly unit can be used as it is or can be 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.

  • * Unit assembly CAD data consists of some sub-assemblies.
       Each sub-assembly unit can be used as it is or can be edited.

Application Overview

Purpose

  • A process where a cap is press-fit into a plastic casing.

Points for use

  • Manual operation for small-quantity production.

Target workpiece

  • Plastic cap
  • Approximate workpiece size: 40 x 29 x 12mm

Design Specifications

Operating Conditions or Design Requirements

  • External dimensions: W200 x D250 x H316mm
  • Press fit stroke: 30mm

Required Performance

  • Pushing force: 50N or more
  • Operating load: 10N or less

Selection Criteria for Main Components

  • Device mounting stand
    • Select an economical shaft with a large diameter.

Design Evaluation

Verification of main components

  • Verify that the cap pressing force meets the required operating load.
  • Relationship between handle operating load and pushing force
    • Conditional values:
      Pinion pitch circle radius rm = 24mm = 0.024m
      Operating load Fs N
      Pushing force F N = 50N
      Pinion center - Operation point R m = 160mm = 0.16m
    • F N = Fs x R/r
      Operating load Fs = F / R x r Thus, Fs = 50 / 0.16 x 0.024 = 7.5N
      ⇒Meeting "Necessary operating load of 10N or less."

Other Design Consideration

  • For most O-ring applications, the groove shapes conform to JIS standards. However, different shapes are used for this application.
