Eg combustion engine is not reversible because you can't turn the crank to produce gas, while some electric motors are reversible because they can work as generators as well. Perhaps there is a better English word for that, but I don't know it. | |

You revealed the truth and its really disappointing that worm gears are required to hold loads, given that they can never be 1:1. Also, Google sucks because you need to know the answer before you can look things up. For example, without typing 'worm gear' or 'worm drive', try to find the answer to my question on Google. If someone can do this, I'll be VERY impressed. PS. Don't link to this page you're reading right now ;) | |

While I assume that inside the window motor from the image above there is a worm drive, I would love to see proof that it actually is one somewhere on the internet. Better if its a manual rather than an electric window so that it can be clearly exposed. | |
| Jul 15, 2016 at 20:30 | comment | added | Pᴀᴜʟsᴛᴇʀ2♦ | Yet a worm drive is reversible. How would the window roll down and then back up otherwise? Maybe you'd like to reword what you've said to say it more accurately? | |
