A lubricant transfer arrangement for a lubricant supply for a transmission includes an outer transmission component, an inner transmission component rotatable relative to the outer transmission component and a plain bearing supporting the outer transmission component on the inner transmission component. A lubricant pocket is formed between the outer transmission component or the inner transmission component and the plain bearing, and a lubricant channel is designed to lead through the outer transmission component, the plain bearing and the inner transmission component to supply a transmission element to be lubricated provided at a downstream end of the lubricant channel. The lubricant channel runs past the lubricant pocket. A leakage groove is formed between the outer transmission component or the inner transmission component and the plain bearing to fluidically connect the lubricant channel to the lubricant pocket.

A plain bearing bush includes a cylindrical main body having a first shell surface and a second shell surface. The first and second shell surfaces include a plurality of exchange bores for a lubricant. At least one of the exchange bores has a first diameter on the first shell surface and a second diameter on the second shell surface, with the second diameter being greater than the first diameter for an increase in a load-bearing capability of the plain bearing bush. Two of the exchange bores are arranged in axial spaced-apart relation and connected to one another by a pocket depression.

A vertical mill gearbox includes a drive shaft mounted in a casing for rotation about a rotation axis, and an intermediate shaft configured as a hollow shaft and mounted in the casing for rotation about a vertical second rotation axis. The intermediate shaft has a bevel gear meshing with a bevel-gear pinion of the drive shaft. A torsion shaft is received in fixed rotative engagement with the intermediate shaft and sized to extend beyond the intermediate shaft to define a projecting section to which a sun gear rotatably driven via the intermediate shaft is fixed. A planet carrier is mounted in the casing for rotation about the second rotation axis and rotatably supports an internal gear having an internal tooth system. Mounted to the planet carrier is a rotatable planet gear which meshes with the sun gear and with the internal tooth system of the internal gear.

A planet carrier arrangement includes a bearing assembly having first and second roller bearings and a traction element having a first end supported by the bearing assembly such as to enable the traction element to oscillate. A planet carrier is mounted in a suspended manner to the traction element, wherein one of the roller bearings of the bearing assembly is configured to absorb an axial force seeking to lift the planet carrier.
