what are you rendering in, what's your normal map look like?

I think your cage is too small, so at some points the lowpoly acually is bigger than the cage.

The small indent is probably also not grabbing well because it's at a 90 degree angle. I'd say remove the inset (make the top of the large cylinder flat) which should also save a nice bunch of triangles.

Have you tried reading all the resources on normal mapping, that lies on polycount and on the web?

To give you some help, here you go.

Please post your actual normal map. It looks like you have problems from intersecting geo on the bake.

Also please highly the areas you're talking about, as it isn't clear from the images.

Where is that area on your normals?(uv layout)

here , you can see there is noo black area here .. i try to export it to UDK and apply my normal and work good

Possibly something corrupt with your mesh normals. Try resetting xform, importing and re-exporting your mesh, or adding another smooth normals modifier(I think thats it, im not max guy) to your mesh

Why does that tiny little pin piece take up so much space on the normal map? You really should adjust the pieces so they are roughly the same textel density. TexTools has a good Normalize function included. Also packing with normalize clusters turned on will get the job done.

Also you might want to think about welding the side pieces on so you're not creating more seams that can be difficult to deal with, at least on the top edges that are highly visible.
