6.05:1 Speed Reducer Gearbox Powered by Toshiba B0252FLG3UMH02 AC Motor STEP CONVERSION MODEL

Last crawled date: 1 year, 11 months ago

NOTE: THIS IS THE NEUTRAL .STEP FILE FORMAT VERSION OF MY DESIGN. AS A RESULT, THE CONSTRAINTS THAT ARE PRESENT ON THE ORIGINAL INVENTOR .IAM ASSEMBLY ARE NOT PRESENT. THIS MODEL SERVES AS A VISUAL AID. FOR THE ORIGINAL 2020 INVENTOR MODEL AND ASSOCIATED FILES, REFER TO THE "6.05:1 Speed Reducer Gearbox Powered by Toshiba B0252FLG3UMH02 AC Motor ORIGINAL MODEL" UPLOAD IN MY PROFILE.

I designed this model for academic reasons but I thought it would be nice to share it with the GRABCAD community.

As mentioned by the title, this gearbox is a 6.05:1 reduction power train. It features a
1:1 ratio synchronous input belt which serves as a sacrificial clutch and then a 2 stage reduction from 2.2:1 ratio to 2.75:1 ratio for a total of 6.05:1 ratio. The input and output shafts are equipped with Love-joy type flexible couplers for universal application. There are also fill and drain plugs that are conveniently located on the case. This gear box is powered by a Toshiba B0252FLG3UMH02 10HP AC motor that sports a 1.875" keyed shaft. Note: I did not design the motor and the model was provided by Toshiba. It is interesting to note that almost all of the parts are commercially available with/without machining modifications. The drawing files have notes as to the relevant modification. Though this design was created to be the power plant of a large industrial band saw, it can be used in a variety of applications. Much of the design and material choice stemmed from my automotive technician along with manufacturing experience. If you would like to see the decision making process, I have also attached a write up to this project. The .DWG's and .PDF's of each part are also attached. If you would like to see a demonstration video of the gearbox in action, please refer to the "Prototype Demonstration Video.mp4 file"

Final Note: This model was designed in Autodesk Inventor 2020.
