Inspired by the earliest tower mill in England, the Ugears Tower-Windmill model has a unique mechanism inside with a full-fledged chain drive made entirely of wooden materials.
When spinning rapidly the aerodynamic twist sails create fairly strong wind.
It also can work the other way around: blowing air directed at the sails will make them spin. Use a fan to demonstrate to your kids how real windmills operate.
The rotation of the windmill sails is mesmerising. You can’t stop watching them turning over and over.
A double planetary gear reducer with differently shaped gears provides the necessary speed.
The model is powered by a removable rubber band motor.
Once the motor is removed, the Windmill can work in a manual mode that allows you to observe and examine the fascinating complex mechanism in detail.
The rubber band motor drives the sails by means of a screw conveyor (worm feeder) and gear transmission.
The design of the gear transmission includes a flexure link, the type of chain drive assembled out of many small links.
The full-fledged chain drive made out of plywood has never been used in the Ugears models before.
Resembling a spiral staircase, the rotating base of the arched tower is a part of the screw conveyor mechanism that is a chief part of the model’s mechanism.
Fascinating mechanics of the moving gears will captivate your attention for a long time.
While taking origin from the Chesterton Windmill, the Ugears model also addresses the Spanish classic: the Tower Windmill can be completed with the figures of the Ingenious Nobleman Don Quixote and his quirky companion Sancho Panza.
