: これが解れば手作業を機械化・自動化が高い確率で出来ると思う話

2025/11/13 Mechanization/automation

今日は「これが解れば手作業を機械化・自動化が高い確率で出来ると思う話」をしたいと思います。ここ数年、自動機械を設計してきた中で解ったことのメモです。手作業の機械化・自動化 ...

: Types and characteristics of nitriding treatment (note only the essentials)

2026/1/31 Surface treatment

Here are some notes on "nitriding," one of the hardening methods. There are many different types of nitriding, so here are a few of ...

: Design method for using knock pins and parallel pins as positioning

2025/10/19 Knock pin/Parallel pin, Method of positioning, Design method

Here is a note on "How to design when using knock pins and parallel pins for positioning" mentioned in the "Complete Guide to Positioning". First, there are two major types of positioning for mechanical parts ...

: Calculation to determine wind pressure (how much force is being pushed per area) from wind speed

2025/11/13 Basic calculations

Today, I couldn't figure out the wind speed estimate, so I'll leave a note about "calculating wind pressure (how much force is being pushed per area) from wind speed". It is not particularly difficult. How much force per area does the wind speed push ...

: Consideration and load calculation of cross roller rings

2025/10/19 Bearing

Today's note is about "Cross Roller Ring Considerations and Load Calculations" Since THK's cross roller ring calculations are not on the manufacturer's website (I don't think), I made the calculations based on the information in the catalog, and the cross roller ring thing ...

: [Preservation Edition] Difference between knock pins (dowel pins) and parallel pins and how to use them.

2025/10/19 Knock pin/Parallel pin, Method of positioning, Design method

Today's note is about the difference between knock pins (dowel pins) and parallel pins and how to use them. I researched and summarized the difference between knock pins and parallel pins and how to use them. If you are looking for a positioning pin from now on, please refer to ...

: Study and Calculation of Torsional and Bending Strength of Ball Screw Shaft Terminals

2024/1/20 Ball screw

Today's memo is about "consideration and calculation of torsional strength and bending strength of ball screw shaft ends. In the selection of ball screws, some people may be surprised that they do not calculate the strength of the shaft end. In the past, I have discussed the ball screw axial allowable ...

: Good news] We found out in the chat. Even if the manufacturer doesn't have it, MISUMI may carry it.

2020/10/9 Misumi

Today's note: "MISUMI may carry some items that are not available from the manufacturer. The other day, I was researching couplings that connect a servo motor to a ball screw, and I found that the manufacturer I was aiming for (...

: How to calculate allowable load for "buckling, tension, and compression" in ball screw axial direction

2024/1/20 Ball screw

Today's note is on how to calculate the allowable loads for "buckling, tension, and compression" in the ball screw axial direction. There are two steps in using this calculation form. When pushing a heavy object at an arbitrary acceleration, the ball screw ...

: What is TRIZ, a method for efficient invention?

2025/10/19 TRIZ, The story of machine design

Today's note is about "What is TRIZ, a method for efficient invention? Have you ever heard of TRIZ? In the development of ...
