rotating in an oven question 1

[juicepluslady]

is there a way to create a device that would rotate in an oven? all I could find was info on rotisserie ovens. I am thinking a cross between a timer and a wind up toy.

Thanks.

You want a wind-up timer in your oven? Not sure that I'm following. Can you elaborate on what you're trying to do? Is this a food oven?

what about the wind up tables in old microwave ovens

 

[juicepluslady]

it is for an invention I am thinking of. but it would need to be able to rotate in an oven- a kitchen oven.

I will check on the wind up tables in old microwaves.

thanks,

I have two microwaves that "turn". Never took one apart to figure out how they work - but they are obviously motorized.

If you are real curious - you can buy a brand new one for about $70!! Or go to Goodwill and find one for about $10.

As long as it's designed properly, you should be able to make a device that can rotate and operates under high temperatures. You might want to consider graphite impregnated plain bearings to avoid using oil or grease.

You're thinking of a wind-up device, so I'd imagine that there's a spring involved. You may want to look into high temperature materials for highly stressed parts like that: Inconel for example.

Good luck with your design.

thanks for you help!

I have to think that there must be a better way. Perhaps a more detailed description of what you're trying to achieve may help.

They used to use little dogs so I have been informed to drive spits.

Most domestic ovens user cheap geared sync motors like following:

these are outside oven and don't take full impact of heat

Can't you do anything with magnets outside the oven?

 

[CastMetal]

Maybe I'm mistaken, but isn't heat generally evenly distributed in a kitchen oven front to back, side to side. What is the goal of this device if it does not rotate similar to a rotisserie?

Comprehension is not understanding. Understanding is not wisdom. And it is wisdom that gives us the ability to apply what we know, to our real world situations

 

[KENAT]

Look in an antique store, long ago rotisseries did used to be spring powered (I saw Jamie Oliver use one over a camp fire on a TV show).

Now I'm not sure they were directly over the heat/in the oven but it might give you a starting point.

As others say, if you can better explain what you're trying to do someone may come up with another avenue to explore.

thanks for the help.

I am looking to make a kind of turntable that is not electronic that can be taken in and out of the oven for a project I am working on.

"a kind of turntable that is not electronic that can be taken in and out of the oven "

But if you're rotating the oven, why is the turntable inside the oven?

not rotating the oven= rotating the turntable in the oven

 

[btrueblood]

What upper limit temperature, what rpm, for what duration?

Mechanical spring motor gets tricky above 200 F or so, due to softening of typical (cheap) spring steel.

Can you bore a hole for a shaft in the floor of the oven?

 

[juicepluslady]

No, but thank you all for your help.

Pulley underneath a turntable, sheathed steel cable loop from pulley to a motor that sits outside the oven (close the oven door around the cable)

Turntable heavy enough to not move, or add clips / protrusions to catch on the oven rack limiting rotation until they hit the wires.

Mag base to oven door (wide enough that torque from the motor does not spin it off of the door, probably 2 magnetic feet)
