Definitions
- the invention relates to a rudder propeller with a planetary gear comprising underwater transmission, wherein the planetary gear comprises a sun gear, a fixed ring gear, and between the sun gear and ring gear and mounted on planetary axles of a planet carrier planet carrier.
- Rudder propellers of the type mentioned are known for example from DE 28 43 459 A1.
- the rudder propeller is used for propulsion and control of a watercraft, wherein the engine torque of a drive motor usually disposed within the vessel is transmitted from an overhead drive via a vertically downward drive shaft to an underwater transmission, which usually comprises an angle drive and a downstream planetary gear from where the motor torque is ultimately transmitted to the horizontal propeller shaft carrying the propeller.
- the underwater transmission is arranged in a housing rotatable about the vertical axis for the purpose of controlling the watercraft.
- the object of the present invention is therefore to avoid the disadvantages of the known embodiments and to ensure an increased life and reliability of such a rudder propeller at low cost and easy installation.
- the invention proposes to support the planet wheels by means of hydrodynamic slide bearings on the planetary axes, so that the entire width of the planetary gears and the maximum diameter of the same becomes usable, which is reflected in higher rigidity, longer life and reduced wear.
- this pressurization can be realized via the feed channels of the already existing lubrication system of the rudder propeller or separate lubricant pumps are provided for this purpose.
- the control can be made speed-dependent by a corresponding control device of the rudder propeller. Once the speed range is reached in which liquid friction prevails due to the prevailing relative speed between the sliding surfaces, the supply of lubricant can be switched off via the supply channels, since then it is no longer necessary.
- the feed ports are connected according to a proposal of the invention with a common, formed in the planet carrier supply channel for the lubricant such that they communicate with each other.
- a central lubricant supply is created within the planet carrier, which is in all, outgoing from the planet carrier planetary axes for the individual planet wheels branch.
- a planetary gear comprises at least two, preferably three such planetary gears together with planetary axes.
- the pressure of the lubricating agent which can be applied to support the start-up or run-off of the planetary gear lies in a low pressure range of a few bar, which can be easily realized by the already existing lubrication system of the rudder propeller.
- the hydrodynamic slide bearings are advantageously formed on their outer surface facing the planetary gear with a circumferential groove into which the feed channels open, so that the lubricant film can form directly around the hydrodynamic slide bearing.
- the planetary axes are used on one end face of the planet carrier protruding in corresponding receiving holes, preferably shrunk.
- the planet wheels are mounted by means of the hydrodynamic sliding bearing flying on the planetary axes, so that it is possible to use the entire tooth width of the planet gears for power transmission.
- the planetary gears are secured according to a further proposal of the invention on the side remote from the planet carrier by means of a thrust washer against axial displacement on the planetary axis.
- Figure 1 is a fragmentary view of a planetary gear according to the invention
- Figure 2 shows the underwater transmission of a Rudderpropellers after
- FIG. 2 shows, in a simplified schematized illustration, the underwater gear of a rudder propeller according to the prior art.
- the fixed ring gear 4 is not shown in detail, e.g. connected to the housing, not shown, of the underwater transmission.
- the planet carrier 2 is shrunk onto the propeller shaft 1, so that the rotational speed of the drive shaft 10 is reduced after being deflected by the bevel gear 8 from the planetary gear into the slow and in this reduction, the propeller shaft 1 is driven.
- the roller bearing used in the illustrated embodiment of Figure 2 on the bearings 5a of the planet gears 5 is very susceptible to wear because of the alternating loads occurring.
- a hydrodynamic sliding bearing 50 which supports the planetary gear 5 on the planetary axis 3, is mounted on the planetary axis 3.
- the planetary axis 3 is shrunk into a corresponding receiving bore 21 of the planetary carrier 2 and has an axial first of a one Feed opening 300 extending supply channel 30 for a lubricant, which branches off at a right angle outgoing and leads to a formed on the outer surface of the hydrodynamic sliding bearing 50 groove 50.
- the feed opening 300 of the feed channel 30 communicates with a feed channel 20 formed in the planet carrier 2, so that it is possible to guide a lubricant flow via the feed channel 20 into the individual feed channels 30 by a lubricant pump, not shown in detail, for example the usual lubricant pump provided within the underwater gear , which will be explained in more detail below.
- the hydrodynamic sliding bearing 50 and the planetary gear 5 mounted thereon are secured by means of a thrust washer 51 against axial displacement on the planetary axis 3.
- the rudder propeller be put into operation ie, the drive shaft 10 and the downstream parts of the underwater gearbox are set in rotation
- a lubricant flow at a pressure of less bar for example up to 3 bar the feed channel 20 and the adjoining these feed channels 30 in the circumferential groove 500 of the hydrodynamic sliding bearing 50 pressed to overcome the occurring at low speeds or speeds mixed friction within the hydrodynamic sliding bearing 50 as quickly as possible.
- the mixed friction which decreases with increasing rotational speed, changes into the fluid friction characteristic of the hydrodynamic slide bearing, the lubricant flow or the pressurization with the lubricant via the feed channel 20 and the feed channel is interrupted.
