Pgsaw worm gear motor backlash

what is "pitch dp?"
I'll message pgsaw and ask if they know, let me know other questions I should ask, the seller seems to provide great customer service, and if they know or if it's easy enough to measure they'll likely pass it on

I addressed this before. Depends on what bugs you more. Clacking or squeaking. Personally i find the scn blend more into the game sound, racing anyway, than the clack of the backlash.
I dont use headphones but play somewhat loud and the scn dont bug me at all. I dont even notice them except between dirt rally stages. Maybe because ive driven a 70 beetle like a race car most of my life a little suspension squeak sound normal

Diametril pitch, but I only know that from skimming that catalog as they are sorted by a few categories and one of them is DP (DOP in metric) and by no means am I the guy to figure out the right gear replacement, just fishing for someone that is.

That being said with the righ amount of research anyone could more than likely find it if it does indeed exist. Would just be nice for an expert to weigh in. If we need custom we could try a group buy as im sure you'd need some fairly large enconomies of scale to make it worth it.

Thanks!

and @PiaMan thank you too...I spent my first 30hours reading about SCN, and was super close to going SCN6, in fact I would have but a place that had them at a lower price only had 1... a month or so ago I switched "gears" to worm, and I have no clue why Oh well, and I appreciate you chiming in! Now I'm like, well what's the $200 difference per axis when you're spending X amount on amps and bass shakers, wheels and throttles, pedals and joysticks, me oh my

pgsaw unfortunately did not have the DP data

@gSeat i did a dig around and many of the gears as rated at very low torque and the ones that are rated for similar use as ours are way too big.

For the money you could could ditch the gearbox and make some small diy actuators to removed the lash issue. I'm working on designing somthing along those lines to build in the new year.

reIY actuators, definitely, but as my first build and new to all this hardware design(even just copying exact builds), it's a little daunting. Look forward to seeing another DIY actuator build

If you find the right wormwheel, you need a press to get the old one off!

I have more free play than you think, it is quite annoying the noise it makes, I give it a lot of positive charge to be able to notice the small details, I think I have to play inside, can it be by axial play on the endless screw? To open the mcp 4 I have to remove some riveted screws, I do not know how to remove them yet ..

Somewhere there is a how-to on drilling them out and replacing the rivets with screws. I know that’s not any help but maybe some searches will turn it up. I just know I’ve seen it.

They are Allen screws but they have drilled and it has been round to not remove them, have you opened your boxes? Have you seen anything that has more free play than normal gear?

What do you mean by the inner reinforcement in the gearbox?

in your post
"I also beefed up the motor mounts. Internally there is now an additional steel plate with welded nuts over the top of the existing internal angle bracing."

@evolaco

My gearbox is also connected via allen screw rather than rivets. I opened one up to flip the orientation of the shaft mount. You can see that here:

2DOF Compact almost-no-weld aluminum build

I removed the gearbox from the motor, which was easy, and then removed the allen screws. After the screws were removed it was still pretty tightly connected so I took a punch and at each screw-hole lightly knocked the two halves apart from one another, and then the center shaft.

The box casing is pretty tough, but I'd recommend being gentle with your punch and use a wood block when attempting to loosen the the center shaft.

Hi Zed!
For my sim i use ZYT90-155-12 MCP4 60:1 and same backlash.
Now i've just found these motor...see pdf attached . 12V 300w 1700rpm 0,80nm - with gearbox 30:1 60rpm and 27.5 Nm. Not bad.The motors ad gearbox seems stronger than ZYT and MCP4 series but I don't know if this different gearbox have the same backlash problem. Someone that use this type of motor probably could let us know their opinion

Supplier asked Usd 95,00 for each motor plus shipment.
4 motors and shipment to italy 95x4+180 total 560usd
At this amount it's necessary add custom tax

Today I was from a local company that builds gears to show the mcp4 gearbox and ask if it is possible to convert a worm gear coupling with reduced tolerance to eliminate the backlash. They replied that they must check the measure for the pace of my gear but think they can do it. They also explained to me that a worm gear coupling with reduced tolerance is better than plastic, not steel or bronze. Above all, the cost is lower
They also suggested me to insert a micrometric thickness on the worm screw. For a plastic gear they ask me for 50.00 Euros. Obviously for larger quantities the price could be reduced. I asked that they verify and try to make two of them. I will keep you updated by posting a video of the new gear and reduced backlash.
