P60 planetaries gearboxes

[Rosiebotboss]

Has anyone ordered and received one of the new P60 planetaries? (With either a F-P or a RS 545 motor on it.) How are they holding up? Any problems surface yet? Is BB shipping on time?

We are looking at the 64:1 with RS 545 motors for our ball conveyor system.

We ordered 4 of the 16:1 but we havent received them yet. we will post up as soon as we get them. We arent going to be using them in a particularly high stress area though

How long did it actually take?

seemed better than a week

We ordered them last Monday (1 week ago) and have not received them. At the time, it said there was a 2-3 day delay. It now says there is a 5-7 delay and that orders made last week will ship on Wednesday or Thursday.

I ordered two on January 15 and received them via priority mail on January 24. We haven't had much of a chance to play with them yet.

We ordered P60 16:1 gearboxes the evening of January 19th and just received notification that they are shipping today January 27th. Shipping is USPS , wish they would use UPS or Fed Ex. There was no communication between order confirmation and now. The delay is painful but they must be hammered so we remain patient . Plenty of other things to work on ....

Everyone,

Thanks for the interest in the P60s.

Given that these are a new product being used by a good number of FIRST teams, we thought it might be good for us to monitor this thread and provide answers to questions that may come up. We would like to give credit to the person who called and suggested we do this, but honestly we forgot to get his name.

Please ask any questions you have concerning the P60s and we will respond to them as fast as we can. Please understand that we do not continually monitor this forum so it may take a little time for us to post a response.

It seems the largest question right now is around delivery time. We have been working 7x24 to meet the demand for the P60s

All orders for P60s placed before 1:00PM Mtn time yesterday (Jan 27th) have shipped.
Orders placed yesterday afternoon or today will likely be shipped on Thursday or Friday.
Orders placed Wednesday – Friday will likely ship next Monday.
Starting next week we hope to maintain about 2 days from order to ship.

We do not anticipate any problems or delays due to materials, all lead times are a direct result or machining and assembly times.

A few things to note:

- The screws on the 64:1 are a bit short. They engage enough to hold but longer would be better. We have not been able to find an affordable source for the 2-1/8 inch long screws so we had to go with the current 2 inch screws. If you are worried, you can pick up some 2-1/4 inch screws and cut them to length.

- The grease used is not critical. We use Mobil XHP 222 Special, it is readily available from many sources includnig McMaster, Grainger, and MSC. Some people have chosen to get the gearboxes with no grease and use a light oil (you might be surprised how much resistance the grease adds.) We can't directly recommend this but have found that it works OK for intermittent use. Keep in mind that you can (or will soon be able to) purchase the gears separately if you push it too far

- When assembling the gearbox, ensure that all 4 spring pins are in place in the front block. They keep the ringgear from spinning. Only two engage at a time depending the the direction. If one is missing in a high stress application, the other may push out and allow the ringgear to spin.

- The blocks on some of the geasrboxes are a bit tighter than we planned, we have adjusted to correct for it. There is nothing holding the gearbox together besides the 4 long screws. If you are having trouble separating the blocks and the ringgear after removing the screws, you can gently tap the blocks to remove them.


Please post comments, questions, and suggestions. We appreciate candid feedback and will try and respond in a timely manner.

We just received our 16:1 and 64:1 P60 gearboxes. I hooked up a 64:1 to a RS-545 and a 16:1 to a FP motor whose shaft I cut to match the length of the RS-545 (and swapped out with the appropriate pinion of course). Both motors draw over 30 amps, no load; no extra load anyhow.

Of the three things I fiddled with (4 ring gear clamp screws, 2 motor mount screws, and the pinion) the pinion location seems the least idiot proof. Can anyone offer up a CAD file, or at least a distance from the back of the pinion gear to the front of the motor location boss that results in acceptable "no load" load? That or how far a stock rs-545 shaft is proud from the front of the pinion face (positive or negative).

Thanks,
Travis

Can the P-60's be face mounted? We would have gone with them, but it didn't seem like you could face mount them. It looks like you might be able to get longer screws (the ones early mentioned that hold the whole gearbox together) and use those to face mount it, but I'd be worried that it would compromise the structural integrity. Is this doable? Is there any way to face-mount them or do they have to be mounter from the side?
