[TowerTalk] Rotor damage prevention

[Mike Harris]

G'day all,

| spur gears. I decided to replace it with an Italian worm gear unit. I
| also decided to try and reduce the mechanical "shock" load placed on
| the "parked" rotor, during high, and gusting wind conditions, by
| fitting a rubber doughnut drive coupler

PST make a "flexi mount clamp" for the PST2051 and there is a picture of 
it on the Array Solutions site.  To fit it on my PST61D requires 
fabrication of a mounting plate.

The PST61D's 1870lbs vertical load capability (the thing is built like the 
differential of a small car) means in my application on a tilt over tower 
I don't really need a thrust bearing though I do have a Yeasu GS-065 unit 
at the tower top.  There doesn't seem to be any radial load spec. for the 
Yaesu bearing and given that this is the point where the radial loads of 
mast flex are located I don't feel particularly comfortable with it.

Time will tell and in the meantime I'm looking for a sturdy flange mounted 
radial bearing to replace it with.

Regards,
