Posted: Mon Nov 14, 2011 5:40 am Post subject: Fit of wheels on shafts

Hello group!

  

 I am fabricating the shafts for the 601 wheels and I noticed that on the XL, the shaft for the nose wheel is made out of 6061-T6 alum (please confirm).  

  

 Two questions that apply to both main and nose wheels:

  

 1. Should the wheel bearings slip easilly on the shafts or should they be pressed in?

 2. What technique is used to prevent the bearing from spinning on (and wearing) the shaft? (retaining compound? side pressure or compression?)  I did not think that side loading was a good technique on ball bearings (like that of the nose wheel)

 

  

 Thanks all!

Hi Michel,

I cannot speak for the axle material, but it would seem better as a 4130 tube with long thru-bolt.  As for fit, the bearings should 

be a slide-fit with .001 clearance plus or minus .0005.  The axle shaft should have a sleeve each side of the bearing

that allows the bolt to be tightened on the fork and sleeves, which in turn take a bite only on the inner bearing race. 

This makes for easy assembly, centering on the axle with no wear or incidental rotation.  

Side loads are not a factor so long as the sleeves only contact the inner bearing race.

It may be different with the newer kits, but my nose-wheel axle is a steel rod threaded on both ends. Three steel spacers fit over the axle and hold the inner bearing races in place. the torque on the axle nuts put side pressure on the inner races, preventing them from spinning

[Barry] - YES - Aluminum - Yes, 6061T6.  Could also be 7075 but either are OK.

[Barry] - The axle/shaft is SMOOTH - VERY Smooth.

The bearing just slips on - About a 0.005" clearance <-- Guessing here.  NOT PRESS FIT.

There is NO side load unless you land in a crosswind.

 They work by being held in position by the step in the axle and the nut.

ALWAYS tighten the nut so there is DRAG on the wheel. About 1/2 to 1 rotation with medium hand rotation.  <--- Don't ya just love those exact requirements    Otherwise you will ware away the step on the axle.
