Re: Rack'n'Pinion ideas for RA28	Wed, 10 December 2003 20:41

Hi Joel Phasing is one of those things that is visually easy to demonstrate but quite hard to describe in words. But is basically used to cancel or lessen the the variation in angular velocity across a UJ as they are not constant velocity joints. As I said not easy to describe so I will let someone else do it! (Although this is specific to propshafts it is just as relevant to UJ's in a steering system.) http://www.custompistols.com/cars/articles/ts_ujoi nts.htm The effects of phasing are obviously worse on a propshaft due higher rotational speeds, but on a UJ equipped steering system it can result in binding and tight spots. If you look at the photo of my setup and start at the rack. The yoke attached to the spline on the rack has no reason to be phased as it has no partner joint to phase to. The next yoke up attached to the bottom of the short shaft, requires phasing to the yoke at the top of the short shaft and as can be seen, the shaft through each of these yokes is parallel and therefore in phase. The double UJ is no different really, it is just 2 yokes at the ends of a very short (integral) shaft and without cutting the shaft in half and welding back together offset by 90 degrees will always be in phase. The last yoke at the top of the picture must be phased to the last UJ in the system which is on the other side of the bulkhead. Did that make any sense? To be honest though this does not sound like the problem you have described. Phasing should really only cause tight spots. If your set up is twisting and looping as I think you were describing this is purely a function of support, or more importantly lack of it. As soon as you get that rose joint on the shaft it will all make sense. I know when I was mocking up my system and tried running it without the support bearings, no matter how well you think you are supporting it with your hands it just ends in a looped up mess. Again I hope thats some help Cheers Gareth [Report message to a moderator]
