The invention relates to a transmission (), preferably a bevel helical transmission, having a transmission housing () and having a drive shaft (), on which a fan () is mounted, and comprising a ring cooler (), which surrounds the drive shaft (), oil lines () for transporting transmission oil in an oil circuit from the interior of the transmission housing () to the ring cooler () and from the ring cooler () into the interior of the transmission housing (), and an air-guiding hood () surrounding the ring cooler () for guiding air suctioned by the fan () onto the ring cooler ().

Transmission and use of a ring cooler

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.

Vertical mill gearbox

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.

Planet carrier arrangement, vertical mill gearbox and vertical mill

A gearing arrangement for a vertical mill includes a central shaft mounted for rotation about a vertical rotation axis, a spur gear arranged in fixed rotative engagement on the central shaft, and an output flange rotatably coupled to the central shaft. At least one gear unit having gear pairs is arranged vertically below the output flange, with a pinion gear arranged on an output side of the gear unit for engagement into the spur gear on the central shaft. The gear unit is arranged on a traversing mechanism in such a way that the pinion gear on the output side is movable in relation to the spur gear to engage in and disengage from the spur gear, as the gear unit is moved by the traversing mechanism.

Gearing arrangement for a vertical mill

A drive axle assembly for a heavy goods vehicle includes a hollow hub, a wheel body rotatably mounted to the hollow hub, and a planetary gear including first and second planetary gear stages, each having a sun gear, a ring gear and a planet carrier with planetary wheels mounted rotatably in the planetary carrier and meshing with the sun gear and the ring gear. A drive shaft is axially guided through the hollow hub and the sun gear of the second planetary gear stage, with the sun gear of the first planetary gear stage being non-rotatably mounted on a vehicle-distal outer end of the drive shaft. Non-rotatably connected by a screw and pin connection to the hollow hub is an annular disk which has an axial opening and a plurality of boreholes in radially surrounding relationship to the axial opening.

Drive axle assembly

A mill drive system includes a gear unit which is arrangeable below a grinding plate and has at least one planetary and/or spur gear stage, having a vertical shaft position. The mill drive system includes an electric motor, integrated into a housing of the gear unit and having a rotor and a stator which have vertically extending axes. Upper and lower bearing covers each including bearing seats for rotor shaft bearing are mounted on opposite end faces on the rotor and stator and are connected via a stator carrier, which has cooling fins on the outer periphery. A collecting tray for coolant is formed between the lower bearing cover and a base part of the housing. The motor is supported via a flange which is formed on an inner face of the housing and extends radially inward and to which the lower and/or upper bearing covers are connected.

Mill drive system

A gearbox mechanism is provided for a twin screw extruder having two screw shafts disposed at an angle to one another. The gear mechanism has a multi-stage reduction gearbox, and a distribution gearbox having two output lines connectable to the screw shafts. A first output line comprises a through output shaft. An angularly movable coupling, which is fixed against rotation, is disposed in a second output line placed at the angle of the screw shafts, relative to the first output line, via the coupling. A drive gear of the reduction gearbox is disposed between, and is in engagement with, a gear on the output shaft and a gear on a partial shaft of the second output line. A reduction gearbox and distribution gearbox are disposed, without spatial separation, in a common interior space of a multi-part gearbox housing.
