The invention relates to a high power machine unit. Said invention is characterized by the following features: a drive which has an output shaft; a machine which has a drive shaft; a converter () which is connected between drive and machine and can be filled and emptied; having a toothed clutch () which can be engaged and disengaged and is connected in parallel with the converter (); one half () is firmly connected to the output shaft of the drive so as to rotate with it; the other half () of the clutch is firmly connected to the drive shaft of the machine so as to rotate with it.

A hydrodynamic converter is provided having a pump wheel, which is flowed through in operation from the inside to the outside; a turbine wheel, which is flowed through in operation from the outside to the inside; guide blades between the pump wheel and the turbine wheel; and guide blades between the turbine wheel and the pump wheel. The converter can have a speed ratio of between the speed nof the turbine wheel and the speed nof the pump wheel of between 1.2 and 4 at approximately even or falling &#x3bb; progress. The converter can also have different speed ratios between pump and turbine, which can be realized with the ratio R/r equal to or larger than 1.

Hydrodynamic converter

The invention relates to a hydrodynamic converter comprising a torus-shaped working chamber surrounding the converter axis, said chamber having the form of a ring channel in an axial cross-section; an impeller which is rotationally fixed to an input shaft; a turbine wheel which is rotationally fixed to an output shaft, and a ring of adjustable guide vanes. The converter is designed in such a way that it has a lambda value of less than 0.0005.

A method and device for speed control of a friction clutch in a drive unit having a drive engine and in which the friction clutch includes at least two clutch parts that can be pressed together for purposes of torque transfer. The first clutch part is coupled at least indirectly to the drive engine and the second clutch part can be coupled to the drive engine via the first clutch part. The contact force for the clutch parts required for torque transfer is automatically applied hydraulically at least on achieving the idling speed of the drive engine by rotational pressure of a rotating ring of hydraulic fluid.

The present invention is a drive system for a boat propeller, with a motor and a reverse gearbox. For forward travel a hydrodynamic coupling is provided and for reverse travel a hydrodynamic reverse converter is provided. The coupling is operated with its maximum filling degree in the upper range of the propeller speed, but in the lower range of propeller speed with a partial filling. Thus, the hydrodynamic coupling is the single hydrodynamic power transfer unit for the entire forward speed range. In order for the boat to be able to be quickly braked down from full speed, the reverse converter is arranged to provide a high torque conversion in the reactive braking range.

In a power-transmission unit for variable-speed drive of machinery with hydro-dynamic speed-superposition of a differential gear a second torque converter is provided as a braking device. This increases the effectiveness of the unit by feedback of the superposed output onto the drive side. Particularly advantageous is the use of an oppposed-motion converter as brake converter for certain operating conditions or the combination of a with-motion converter and an opposed-motion converter in the unit. Furthermore, this makes an extension of the speed control range possible.

A hydrodynamic brake has a rotor blade wheel and a stator blade wheel with oblique blades and which together form a toroidal work chamber. A series of quick blades are mounted on the stator blade wheel for controlling the flow of braking fluid between the blade wheels and thereby the degree of braking action. Each of said blades is mounted for rotation around a radial axis and can be swung uniformly by means of a common actuating device. In this basic position, the guide blades are parallel to the stationary blades to provide the maximum flow of braking fluid. In a 'zero position' the blades are all in a plane normal to the axis of rotation of the brake, whereby they substantially block the flow of braking fluid within the work chamber. In order to control the braking action, the guide blades may be brought into any desired intermediate position.

A power transmission system serves to drive a variable-speed processing machine normally in a lower speed range and if necessary in an upper speed range. The system essentially comprises the following elements which are all disposed coaxially to one another: An input shaft connected by means of a hydrodynamic adjustable coupling to an intermediate shaft to rotate the impeller pump of an adjustable hydrodynamic torque converter. Its turbine wheel rotates with a brakable override shaft. The intermediate shaft and the override shaft are connected to an output shaft by means of a differential gear.

The disclosure concerns a venting device for the housing of a rotary machine. The housing has a venting duct leading from the interior of the housing outwardly through a liquid-mist or oil-mist separator. A peeling device is arranged closely adjacent to the peripheral surface of a rotating member of the rotary machine. The peeling device intercepts the boundary layer of mist laden air that is rotating with the peripheral surface and directs the air boundary layer into the venting duct which in turn extends to a liquid or oil-mist separator or filter. The peeling device thus transforms the kinetic energy of the oil laden atmosphere at the peripheral surface of the rotating member into pressure which will drive the oil-mist laden atmosphere through a filter. The peeling device is directed so that it has an entrance opening facing in a direction counter to the direction of rotation of the rotating member so that it will peel off the boundary layer of liquid-mist or oil-mist laden air as the rotating member rotates.
