G'day Jack,
Thanks Jack and Kye for this info.
I did wonder about the black and white image of the new Villager mower as the colour of the fan blades and cake tin looked the
same but I had seen traces of gold paint on the cake tins on old mowers.
The original images of the new Villager Mower suggest the rubber blades were painted gold to match the cake tin .
I don't know if the covers are Champion or Villager.
Any ideas?
The images from Kye I would say are from a Villager Mower as the fan blades are on a roughly 45 degree angle
and the Champion cake top has the fan blades vertical so I would say the idea of the Champion blades
is to have a radial blade fan. Blades are perpendicular to the axis of rotation. Radial Blade design is used for high pressure application. Although low in efficiency the design is excellent for a dusty environment as the dust can't stick on the blades because of geometry.
The Champion mower with its radial fan, the air hits the fan wheel, turns at the right angle, and is accelerated by radial flat blades on the flywheel. The accelerated air is discharged radially, thus, the name. The airflow is induced by the centrifugal force, which is produced in a rotating column
In other words this fan would remove the heat at the top of the motor pushing the heat away radially .
The Villager with its pitched or angled blades, these blades not only push air, but create a downdraft so as to move air efficiently through a space, the downdraft is directed down past the cylinder for cooling
purposes.
Great to finally see a good image of exactly how the original blades were.
Cheers
Max.
