1. A mechanical assembly, comprising:
a first roller bearing including an inner race, an outer race and a plurality of rolling elements, wherein an axis of rotation of the first roller bearing defines a first axial direction oriented horizontally or inclined with respect to the vertical direction,
a source of lubricant configured to deliver lubricant to the first roller bearing, and
at least one movable element disposed adjacent to the first roller bearing on a first side of the first roller bearing in the first axial direction,
wherein the rolling elements of the first roller bearing are tapered and their larger diameter ends point towards the at least one movable element, and/or
wherein axes of rotation of the rolling elements of the first roller bearing are inclined with respect to the first axial direction so that centrifugal forces generated inside the first roller bearing are configured to transport lubricant towards the at least one movable element, and
wherein the mechanical assembly further includes a cover disposed on the first side of the first roller bearing, the cover closing or at least partially closing an annular space formed between the inner race and the outer race of the first roller bearing on its first side, the cover comprising at least one opening disposed such that an annular space formed between an inner race and an outer race of the at least one further bearing intersects with a cone, the cone having an apex located at or within the at least one opening, the cone having a cone axis arranged in parallel to the first axial direction, and the cone having an opening angle of less than 70 degrees.
