As with all thing in engineering there is a compromise to be made and I'll have to work out what it is!!!įind attached photos of the OpenScad gears and the point motor. Optical switches are both accurate and durable but low switching capability and would need extra electronicsto switch the motor. But so far it works well otherwise, I now have to put some limit switches in but am unsure what to use microswitches would be simplest and accurate but may not survive well outside reed switches would surve ok but are not very accurate It instantly broke the end stops I put in and when connected to the points broke the quadrant mounting, that is now made of steel
With gearing the motor down so far, being a humble sparky, I totally underestimated the torque such a small motor would generate. I do not like the motor mounted vertically, I do not know what it's longevity would be because I doubt the bearings are designed for this mounting. The reason for these gears is to build a robust point motor. Apparently it is on the guys list of things to do to make multiple gears.
#OPENSCAD GEARS PLUS#
On the inner cylinder I plan to mount 3 un-powered bevel gears vertically plus a 4th powered one each at the proper location/angle to interface with external cylinder's spiral bevel gear and keep the external cylinder. I discovered why it is printed in two halves, if printed vertically the edges sag and are rounded making a fairly uselessįrom my point of view there are two issues I'm trying to design a 'Lifting Table' in OpenSCAD which will consist of 2 concentric cylinders. The spur gear produced is absolutely fine but I tried to print the worm vertically so as avoid the need to accurately join two halves.
#OPENSCAD GEARS GENERATOR#
I have downloaded OpenScad and the gear generator and had an initial trial at producing a worm drive with moderate success. I would endorse the thanks from Adrian and others to Don for the gear generator.
