75 Type Plastic Crown Gear Single Double Reduction Gear Worm Gear (Original Version)

I needed a gear for my son's chainsaw toy. was looking all over and came across this set. I took a chance to see maybe I will find the correct gear in here. using 2 gears from this set I was able to fix his toy. Great set for small project. lots of variety.

I only used one gear but, all of them seem sturdy and the one I did use is still working with no signs of repair. I used it to replace a gear in a Halloween gargoyle. I don't know what I will use the rest of them for but, hey, I got 'em just in case... lol

If you want to assemble a small gear train for a project, these gears look like a great place to start! They all have the same tooth pitch, so they all work with each other in combination. I have not applied any of these to a project yet, but I have separated them into types (no count of each yet): Multiple worm pinions... Multiple motor pinions... Multiple crown gear idlers... Multiple crown gear compounds... Multiple Idler gears... Multiple compound gears... Multiple drive pulleys... Multiple Idler pulleys... Multiple geared pulleys... Two racks... Multiple Rubber bands as pulley belts... Spacer Bushings... Right-angle bearing (One) Miter gear (only one, but no mate - I bought two sets, both identical, both had only one miter gear) NO SHAFTS All of the axle bores are the same size (roughly 1/16 inch), so they would have to be drilled for fitting shafts.

Just what I was looking for my home project. Little smaller than I thought but that actually worked out perfectly. Great diverse gear set, with lots of different ones there. Highly recommend if your looking for a tiny gear set.

Serving purpose to some motors I mounted on a microscope tray. Only thing is that there is a perfect circle for the center pin parts, not a pin with a notch. so like that's strange in slip theory, you'd e need exact nearly over snug pins for the gears to join onto and hope they don't just slip for cylindrical to cylindrical, I've seen it like this before honest, where the metal pin is so very tight it's tough to remove. It's typical size I think of that, I've glued plastic motor caps with axis I made with a 3D printer to the fitted holes.

They can be used for different mini-projects. I use them to open and close doors and make other things move. Great products have many uses. Just use your imagination. I know you can do it too.

A lot of different gears worm, angle But there small and they are in a small zippy bag.. Almost missed them in the box to the point of contacting azon for a lost item.. Dig around the box if you get them

A nice selection of plastic gears. I needed one for a side brush motor in a robot vacuum cleaner. It was a specialty gear, but I used 2 in this pack you make the one I needed. So for that I give it 5 stars.

Received the item well in time. The items are good and serve my purpose. Thanks.

liked that item was available used to repair 1990's toy car
