Small Turntable 2

Thursday, June 25th, 2009

Here’s a small turntable design using a thrust roller bearing. It’s still a work in progress, but I think I’ve sorted out the main geometry.

Not shown is the matching ring. When assembled, it kinda creaks a little bit. I’ll have to fine-tune things to make it roll smoother. But I think this one will turn out well. I’d like to make a different design for the rollers – I’d like more of them and with smaller diameter wheels.

This design uses the “solid core” concept that I’ve used on some of my other turntable designs. This concept proved to be too flexible for a large turntable, but I’m hoping that it works for a smaller one like this.

I’ll post a part 2 later on when I finalize this design.

I’ve just finished a new medium-sized turntable design that looks like it will work well. This turntable will be used in my new tower crane (see the triangular cross-section truss entry below – these developments are all for the tower crane). I need to take some photos of this new turntable, but I’ll post it here in the coming weeks.
