[Development Case] Contracting for Software Development

[Development Case] Contracting for Software Development

We also have a track record of software development aimed at more specialized or academic fields!

We would like to introduce examples of "contracted software development" that our company has handled. We developed software for performing various calculations necessary for designing buildings, such as "calculation software for building design," and "initial adjustment software for large screens" that displays multiple tiles on the XY, XZ, and YZ planes in a 3D environment. Additionally, we also import and sell a virtual reality software system for large-scale data that allows for the verification of design validity immediately after completion, significantly contributing to the shortening of the design process. Please feel free to consult with us first. 【Development Examples】 <Contracted Software Development> ■ Calculation software for building design: ■ Initial adjustment software for large screens ■ Content creation system for smartphones <Import and Sale of Systems> ■ Virtual reality software for large data *For more details, please refer to the related links or feel free to contact us.

Technical Data: Influence of Rolling Bearing Stiffness and Shaft Stiffness on Gear Engagement

Technical Data: Influence of Rolling Bearing Stiffness and Shaft Stiffness on Gear Engagement

Detailed explanations with diagrams and tables! Includes shaft displacement diagrams related to gear loads.

To model a gear mechanism (gearbox), we will define the shaft shape, select various types of rolling bearings, and set the gear specifications. Considering rotational torque, various load conditions, internal clearances of rolling bearings, and fitting conditions, we will perform calculations for the entire system. In the calculations, we can determine the deflection of the shaft, the stiffness of the rolling bearings, the load distribution, and find the maximum contact stress and bearing life for each rolling bearing. [Contents] ■ Load distribution and life of each rolling bearing ■ Shaft displacement diagram under gear load ■ Line load of gears and gap width ■ Line load under various load conditions *For more details, please refer to the PDF materials or feel free to contact us.
