72001 Planetary Gearbox Set

this gearbox is super nice. I needed a gearbox that would run super slow and steddy so I got two of these and was able to get the exact speed I wanted. it all went together quit well the assembly is simple almost lego like so it allows you to fit it to whatever you want to fit it to easily. To any hobbyist this is a vary good gear box to have lying around

puting it together can be a pain, instructions are ok but need to take it very very slow. also these tiny little tabs that you break off at the start you should really use clippers to make sure its removed smooth to the surface otherwise you may haver some issue like i did at first. But besides that once its all put toogether i noticed with 2 AA batteries as the power source it was able to pick up 6lb weight, i suppoted the other end of the shaft also with a wheel so the rod does not bend, pretty cool.

I didn’t resize how tiny this kit is. Lots of very small parts. I’m in the middle of reworking the kit for a specific small project I’m working on. It saved buying lots of parts individually. There are enough to experiment with. You need some basic gear technology if you are going to modify it. The motor is not real big and it’s easy to lock up the system if you over tighten the screws. It does have a list of ratios for each section and you can change it around if you understand planetary systems. You can simply purchase another kit and get many more parts pretty inexpensively.I’d consider this as an adult toy.. kids could maybe make a science project out of it with some guidance. I hav vision issues so I have to use my lighted magnifying glass an my new forceps to assemble it or modify it but I’m ok with that. It’s probably not strong enough to operate anything requiring lots of torque. Staged planetary systems can create massive torque for their size but this kit is tiny. So don’t expect too much of it.

Simple product and easy to assemble - its even color coded. Good motor too, but does not include a battery hookup. Cool educational toy.

I've built several of these for my vairous robotic projects. The nice things is, you can select your gear ratios. Very powerful planetary gear motor system. Educational, too.

the gearbox is really nice it shows how the gearbox works.

Tamiya makes great project kits. Easy to assemble and very flexible & useful for various nerdy needs.

This gearset is very small. Pieces are cast together on a common molded frame. It says to trim the broken tabs for proper fit. Too small to demonstrate function. I returned and got refund date. 2 week later no refund so I notified Amazon who the notified seller. Seller sent this disclaimer "We outsource sales and shipping to Amazon". So this is where I am now, in the old "not me its them" game. Best not to take a chance on this inferior item and you wont be at this point...

プラネタリーギアの教材として購入しました。 勉強になりとても良かったです。

へらウキのトップ塗装のために購入 専用に作られたものを購入すると 4000から5000円くらいしてしまうので安価で作れたので満足 回転スピードも2種類 2枚ずつあるギアの組み合わせで 1秒間に数回の回転に調整できる

頼まれ物の塗装の際に「吊るして回転させる」必要があり、久しぶり…というか小学校の頃以来のタミヤの工作キットの購入となりました。 パーツはほぼプラスチック製、マブチモーターのRC-260が付属。 (「RC-260はマイコンカーラリーの規定モーターとして使用されます」との事。概ねRE-260と同じと考えて良いかと思います) 組み立て自体に難しい部分はありませんが、ニッパーで部品をカットしたあとのゲートはしっかり処理しないとパーツが閉じないので要注意。 動作している動画は、ギアを全部組み上げてギア比1:400、アルカリ単三乾電池1本(モーターの適正電圧は3.0V)で回してみたもの。 塗装用には少し遅かった為、実際に組み上げた際にはギアを1段抜いて1：80としています いくつか気付いた点としては ・取付用の台座は付属しているが、ベースに固定するネジ類は自分で調達する必要あり 昔の(金属製だった頃の)ギアボックスには、木板に固定する為の木ネジが付属していましたが、今はプラスチック製のベース材料を使う可能性もあり、用途に適したネジを別途用意する必要があります。 (別途購入した電池ボックスも同様でした) ・付属のグリスがチューブのサイズに見合う量が入っていなかった 絞り出すようにしないと出てこないくらいの量しか入っていませんでした。

遊星歯車機構を知りたくて、買いました。教材には良いです。

遊星ギアの原理が学べる教材。性能も十分です。
