This year we are planning on using linear slides on our robot and I’ve noticed that a lot of teams lubricate them to reduce friction, so I have a few questions.
First of all, does lubricating axles change performance since delrin has a low friction coefficient ?
Second of all, I saw that most teams use white lithium grease. The problem is that our robot generally stays in my room so my question is : does lithium grease smell bad ? Because if it does, I don’t want to spend my whole life with the smell of it in my room. If it does, then is it possible to use vaseline (pure petroleum jelly) as a lubricant ?
And finally, how often do you lubricate your linear slides ? Do you just put the grease on once and leave it there ?
I don’t think it really smells, maybe a very tiny bit. But it is quite oily, so it is a but messy when dirt sticks in it, and also stains. After worlds my team shirt had quite a few oil stains on it. I guess that’s what happens if you’re the only one who builds and maintains the robot.
i used to use spray on industrial silicone lubricant
you spray it on, its more like an alchohol rub than oil, and it evaporates quickly.
However, after drying it leaves a lubricative film on the slides, does the job well.
Unless it gets dirty after drying it doesnt smell or stain.
Is that aerosol based? Grease can only be non-aerosol based to be legal.
@botfather, we find if you put not enough or way too much grease it can cause some strange issues… Best practice we have found is to apply grease to a clean paper towel and rub it in on both surfaces to be sliding. You’re looking for a thinnish layer of the stuff.
I hear aerosol and I think of flammable but I doubt it is that. Probably they don’t want a student with breathing problems to be hurt because of no experience or precautions. May also be students at competitions reapplying grease that is the reason.
