Grease that won’t run off a gear?

[Tim Good]

I need to grease the worm gear in “B” but I don’t want it to run off and go into “A” or more importantly not run off between A &B since there should be a dry surface between the two.

the purpose is for A to push into B and lock it in place. Any grease prevents that but yet the worm gear needs some Lubrication.

May be no help at all, but we use some Wurth aerosol at work called HHS2000, and it clings like poo to a blanket, as does Wynns Viscotene, long term use I have no idea, but some searching them products might throw up others that you can use?

I think that the thickest conventional grease I have is waterproof calcium grease but whether that is thick enough for your purposes, I'm not sure.

The thickest grease I have, per se, is probably silicone grease but whether that would be suitable would depend upon the level of stress that the gear is subject to.

Thanks. Arrr I see it’s called adhesive grease. That’s probably the magic word “adhesive”. I.e a grease that stays put.

Maybe some motorcycle chain lube would stay in place?

Agreed, plenty of proper gear greases around. I'd suggest the photo shows too much grease on the worm wheel, is this part of the OP's problem?

That's what I'd try. Chain wax in an aerosol.

Looks like some feature between A and B intended to seal or shield one from the other?

I’d have thought any high melting point grease would do, although I am a big fan of motorcycle chain lube as it sticks like sh1t to a blanket.

Wouldn’t chain lune need applying fairly frequently? Getting to this setup took me a long time so once it’s done it’s needs to last years!

It's a gear so you need gear grease. As post #2 says - it's sticky and designed to stay on.

Presumably winch grease will also do? Harken says “highly adhesive” on their spec...

Only saying as I have some of this already.

Not in a sealed enviroment.

Motorcycle chains only need frequent lube if they are out in the elements.

Many motorcycles have had fully enclosed rear chaincases with oil baths.

They need litte attention or routine service.

Chain lube would stick and stay, but a good HMP grease would too.

We used a Rocol wire grease on dockside cranes and boy was that sticky and as you can imagine out in the elements 24/7 but for the life of me I cannot remember it's name. Silly boy a'int i.

 

[Tim Good]

Anyone got any bright ideas on how to remove a lot of the old grease entirely? Other than wiping a lot that is. Perhaps an engineers will have a special bath that these kind of things go in

I think that stuff is pretty similar to motorcycle chain lube?
It is disgusting sticky stuff, prefer to lube my bike chains with synthetic motor oil. Before and after every ride.

'Wiping a lot' is your mission.
Adding clean lube will displace the dirty lube, then you can wipe some more.

Haynes manuals rate jobs in 'spanners' a 3 spanner job is moderately technical.
I rate jobs on the KR scale.
This looks like a 2KR job, you need two whole kitchen rolls to clean up.

Ok got some of this ordered and the part is currently in a degreasing bath at an engineers. With luck that’ll do the job.

Whatever grease you select, make sure it is designed for extreme pressure use. Worm gears are notoriously difficult to lubricate because unlike spur gears whose faces roll against each other, worm gear interfaces slide. Effectively wiping any lubricant off the mating faces. Several factors need to be taken into consideration such as rotational speeds and whether movement is continuous or spasmodic. Out of curiosity, what is the equipment in which it is installed?
