Definitions
- Rotating machine part in particular the rotor of a cycloidal ship propeller
- the invention relates to a rotating machine part according to the preamble of claim 1.
- a machine part such as the wheel body of the cycloidal propeller
- oil circulates inside, which lubricates and cools the bearings and gears, and from which the heat is dissipated to the medium outside via the outer wall of the machine part. To do this, the oil in the
- the heat transfer surfaces of the machine part are generally radially on the outside.
- the object of the invention is to decisively improve the heat transfer with regard to the machine part cooling or the bearing point.
- FIG. 1 shows an axial section through a Schiff cycloidal propeller and
- FIG. 2 shows a greatly simplified plan view of the rotor (the rotating machine part).
- the propeller consists of the main components stator 4 and rotor 1, which carries the individual blades 2 (generally five in number) by means of the wing bearings 23, 23 '.
- a bearing plate 38 is provided for the upper bearing 23.
- the rotor is driven thereby via the upper rotor part 3, and by means of the bevel gear 14 connected thereto via the bevel pinion 13, primary gear 29, shaft journal 34 and the drive motor, not shown here.
- the adjustment of the propeller blades 2 is carried out in a known manner by the central control stick 5, which is mounted in the central spherical main bearing 20 so as to be movable in all directions.
- the adjusting linkage 7 starting from the hydraulic servomotor 16 for adjusting the
- the joystick 5 adjusts the individual wings 2 via the coupling rods 18 and for this purpose is surrounded in its lower part by a control sleeve 21 or is mounted on the lower end of the joystick.
- the central bore 35 for the lubricating oil opens into the lower part 6 of the rotor 1 with a central introduction point 17.
- This part is essentially a flat, cylindrical housing with a cylindrical outer wall 13. Pockets 40 for the mounting of the wings 2 are formed in this by intermediate walls 42. The lower part of the rotor 1 is covered at the top by a cover plate 41 (see FIG. 2). At least one return line 12 for the oil (heat transfer medium) leads out of each of these pockets 40. This begins in the radially outer region of the pockets and is connected to the upper rotor part 3, where it continues in an opening 39 of this part. Thereafter, the oil continues to rise through holes 24 and 25 which are made in the central main bearing of the joystick. From there, the oil gets into the oil housing 11, which is inserted as a sheet metal insert into the sleeve-like stick housing 9.
- a shut-off in the form of a seal carrier 10 is also provided around the billet, which has a in its upper area
- the invention is based on the following consideration:
- the layered areas form paraboloids.
- the pressures in a stratified area are constant.
- the return lines lead the cold oil to an area near the central area of the rotor, where the oil is returned to the circuit.
- This oil pass results in a wetting of the outer surfaces of the rotor housing 6 with the warm oil up to the outer diameter and a derivation of the furthest cooled oil from the bottom and outermost corner of the wheel center.
