Shaft support for supporting an agitator shaft and an agitator

A shaft in combination with a shaft support,

• the shaft being a rotatable shaft that is rotatable about a shaft axis and that is configured to be connected to and extend downwardly from a drive arrangement for rotating the rotatable shaft about the shaft axis, the rotatable shaft having an outer envelope surface and including a lower portion;
• the shaft support supporting the lower portion of the rotatable shaft and including a support ring having an inwardly facing bearing surface that forms a slide bearing journaling the lower portion of the rotatable shaft, the inwardly facing bearing surface circumscribing the lower portion of the rotatable shaft and having a circular extension that extends circularly around a central geometrical axis of the support ring so that a distance from the central geometrical axis of the support ring to the bearing surface is equal in each point around the circular extension of the bearing surface in a first plane having a normal parallel to the central geometrical axis;
• and
• the support ring being in a tilted position relative to the rotatable shaft such that the support ring is tilted relative to a second plane having a normal parallel to the shaft axis such that the bearing surface has a non-circular shape as seen in a projection in the second plane, a first distance measured in a first direction in the second plane and being a longest distance between the bearing surface and the outer envelope surface of the shaft being larger than a second distance measured in a second direction in the second plane and being a shortest distance between the bearing surface and the outer envelope surface of the shaft, the second distance being less than 70% of the first distance.

• and
• the support ring being fixed in a tilted position relative to the rotatable shaft such that the support ring is tilted relative to a plane having a normal parallel to the shaft axis such that the bearing surface has a non-circular shape as seen in a projection in the plane having the normal parallel to the shaft axis, a first distance measured in a first direction in the plane and being a longest distance between the bearing surface and the outer envelope surface of the shaft being larger than a second distance measured in a second direction in the plane and being a shortest distance between the bearing surface and the outer envelope surface of the shaft, the second distance being less than 70% of the first distance.
