Abstract: A speed reduction gear train comprising a sun gear, an annular gear, and planet gears meshing with the sun gear and the annular gear and mounted in a cage having axial housings between pairs of adjacent planet gears. The cage is connected to a cage carrier having axial arms received in the housings by radial pins disposed in the midplane of the cage by means of spherical finger connections allowing the cage carrier to tilt and to move axially relative to the cage.

Abstract: A high-performance plain bearing provided with a friction coating including a bronze layer whereof the pores are filled with a PTFE-type fluoroplastic paste filled with molybdenum bisulphide. The production method includes sintering a layer of bronze powder on the metal support of the bearing, a vacuum ionic cleaning, applying a filled fluoroplastic film, passing the component through a die and after sintering the paste, a final pass in the die for final dimensioning. During sintering and passing through the die an anti-adhesive and wear-resistant coating, based on titanium nitride or the like, is applied on the equipment.

Abstract: A satellite (3) is supported on its shaft (1) through a large number of distributed bearings, particularly roller bearings (6) and the arrangement keeps a good force distribution capability due to similar stiffnesses of parts of the shaft (1) and a bushing (7) which forms the inner part of the satellite (3), facing each other along the length of the hole.

Abstract: An oil deaerator device for an oil tank comprises a cylindrical chamber having a tangential inlet duct in its lower portion for the introduciton of pressurized oil to be deaerated, tangential outlet ducts for the deaerated oil in the upper portion of the chamber, and an axial outlet duct, also in the uper portion of the chamber, for the discharge of air from the chamber.The device, which operates on the vortex principle, is fitted within the tank in the upper portion thereof above the normal level of oil in the tank.

Abstract: A device for coupling two rotary machines with provision for automatic uncoupling under certain operational conditions, comprising a first shaft and a second shaft in two parts which are connected for motion transmission in a first sense by a dog clutch connection and in a second sense by an intermediate co-axial shaft and transverse pins. In the first sense an accidental excess torque is limited by fracture of a frangible groove section disposed in the first shaft. In the second sense in which a substantially lower torque is exerted, this is limited by the fracture of a second frangible groove section disposed in the intermediate shaft. After fracture of this second groove section, the first shaft and one part of the second shaft will become spaced apart and the one shaft part is maintained in this position by a blocking mechanism comprising at one end a cylindrical bush accommodating a radial spring and balls which are displaced to an internal groove of the other shaft part.
