Ways to Spin a Flywheel using linear motion

Click For Summary
SUMMARY

The discussion focuses on methods to increase the speed of a spinning flywheel using linear motion devices. Participants suggest various mechanical solutions, including the use of a hand drill, a con-rod and crank system, and even a pressurized water hose. The consensus is that while linear motion can be applied, converting it to rotary motion is more effective for driving the flywheel. The conversation highlights the importance of contact time and the practicality of rotary systems over purely linear approaches.

PREREQUISITES
  • Understanding of mechanical systems and motion conversion
  • Familiarity with flywheel dynamics and applications
  • Knowledge of linear motion devices and their mechanics
  • Basic principles of crank and con-rod mechanisms
NEXT STEPS
  • Research the mechanics of flywheel energy storage systems
  • Explore the design and function of con-rod and crank systems
  • Investigate the use of rotary systems in mechanical engineering
  • Learn about the applications of pressurized systems in motion generation
USEFUL FOR

Engineers, mechanical designers, and hobbyists interested in mechanical motion systems and flywheel applications will benefit from this discussion.

I am to try to find simple way to spin a spinning flywheel. What linear motion device acting on the outside edge of a spinning flywheel can be used to increase the speed of the flywheel. Need to use a repeating pattern such as pushing your hand down over and over on the edge of the wheel to speed it up. instead of using hand want to use a mechanical device to do it automatically. Any ideas would be helpful.

Hello Gerald, :welcome:

ANy other boundary conditions? Are you allowed to use a hand drill ? Bow driven axle ? Foot power treadle ?
 
This is very old, but that stick's linear motion spins the hoop. It could spin a flywheel too. Motion of the stick could be done by machine.

Much simpler is @BvU 's suggestion to use a hand drill, but that is rotary, not linear.

Using linear motion, there is a practical limit to the contact time - at least a rotating wheel against the periphery is the most common way of doing what you want in demonstrations I have seen.
 
Why must it be linear?

Edit: Use something like a con-rod and crank to turn what ever linear source you have to the rotary motion required by the gyro/flywheel.

A crank would be a good way for a human operator but a rotary system would probably be better for most other power sources.
 
I used a pressurized water hose to spin a wheel once when I was a kid to study the friction of the bearings on the wheel

There are many clever engineers on PF.

But, unlike many one-off posts, his post managed to spark off some good, interesting ideas.
Must have been a homework topic and he may be getting credit for all these contributions. Ah well.
Was it Picasso who said "Genius steals"?
