- gears are used in thrusters and azipods, for example.
- This application is used for power transmission and power conversion, which takes place between the drive and the propeller. Both an entry of water into the interior and an escape of lubricant into the marine environment are to be expected here.
- Hydraulics in the marine sector are used to drive adjustable propeller rudders, as well as in fin stabilizers and rudder bearings.
- linear guides are also used, which are usually lubricated with the same lubricant.
- lubrication takes place below the waterline. This is also the case in this case water entry into the machine parts and leakage of the lubricant into the marine environment are to be expected.
- the plain bearing application in the marine sector is primarily a propeller shaft bearing, which is located in the stern tube, the so-called stern tube bearing.
- the primary task of the propeller shaft is to transmit the drive movement through the ship's hull to the propeller.
- the bearing ensures low-friction movement.
- This also includes chains that are used, for example, in lock gates, ropes such as ship ropes or ropes that are used in networks, as well as fittings for regulating solid, liquid and gas flows.
- chains that are used, for example, in lock gates, ropes such as ship ropes or ropes that are used in networks, as well as fittings for regulating solid, liquid and gas flows.
- screws, springs and valves have to be lubricated in a wide variety of devices and machines.

- the sample is dissolved in a solvent mixture and then titrated with an alcoholic potassium hydroxide solution in accordance with ASTM D 664-18E02.
- the titration is carried out potentiometrically with the aid of a Solvotrode on a Metrohm 905 Titrando titration unit.
- the molecular weight is determined by means of GPC (gel permeation chromatography) against a polystyrene standard according to DIN 55672-1: 2016-03 "Gel permeation chromatography (GPC) - Part 1: Tetrahydrofuran (THF) as eluent" using a SECcure GPC system .
- GPC gel permeation chromatography
- ATR infrared spectroscopy measurements on the slip improvers are based on the standard DIN 51451 (DIN 51451: 2020-02) "Testing of mineral oil products and related products: Infrared spectrometric analysis - General
- the integral range is halved.
- the respective absolute minima are determined in these two sub-areas. If there are several absolute minimum points in a sub-area, the point is used which is located furthest in the edge area of the entire integral.
- the baseline is calculated using a straight line equation from the two absolute minimum points in the entire integral.
- the spectrum to be integrated is adjusted for the baseline.
- the baseline-adjusted spectrum is then integrated.
- the production of the lubricant compositions takes place according to a procedure known to the person skilled in the art, in that the base oils and additives are mixed in a suitable vessel, e.g. a mixing vessel, using a suitable stirrer. Solid additives or components are brought into solution by increasing the temperature and stirred in. Production can also be carried out by means of continuous processes.
- lubricant compositions according to the invention are prepared as described above (see Table 2 - Examples 1-15b).
- lubricant compositions without slip improvers base formulation
- base formulation lubricant compositions without slip improvers
- Example 16 Effect of the slip improver on the slip properties of lubricants
- the transition speed is defined as the speed at which the contact surfaces separate completely, i.e. the speed at which the transition from mixed friction (i.e. occasional contact of the metallic friction partners / incompletely formed lubricating film) to the elastohydrodynamic (EHL) area (i.e. fully developed lubricating film and complete separation of the metallic friction partners by the lubricating film).
- mixed friction i.e. occasional contact of the metallic friction partners / incompletely formed lubricating film
- EHL elastohydrodynamic
- the tests are carried out using a tribometer (BALL-DISC TRIBOMETER from AC 2 Tresearch / Austrian Competence Center for Tribology) with the test combination cylinder-on-ring.
- a 10 c 10 mm (diameter c length) 100Cr6 steel cylinder with a roughness Ra of approx. 0.02 pm is rubbed against a white metal ring with a roughness Ra of approx. 1.3 pm while applying a defined load.
- the white metal ring is located in an oil reservoir.
- a running-in procedure was performed prior to the start of the test. This included speed ramps from 0.05 m / s to 2.5 m / s and then from 2.5 m / s to 0.05 m / s at 10 N and 20 N at room temperature and at 10 N at 40 ° C
- the Stribeck curve is then generated at 20 N at 40 ° C with a speed ramp of 0.05 m / s to 2.5 m / s.
- 1 shows the measurement of the Stribeck curves for a basic formulation without a slip improver (comparative example 1) and a lubricant according to the invention with a slip improver (example 8). It can be seen that in the presence of the slip improver, the transition speed shifts significantly to a lower speed (A to B).
- Fig. 2 the transition speed of all tested lubricants is shown.
- all examined lubricants with slip improvers (Examples 2, 5, 8, 9, 11) have a significantly lower transition speed than a basic formulation (Comparative Example 1) and a lubricant composition that contains a non-inventive slip improver (Comparative Example 5 ), which indicates that the lubricants according to the invention which contain the slip improver according to the invention form the lubricating film much earlier than those of the comparative examples.
- the improved lubricating properties of the lubricants according to the invention with slip improvers show that they bring about an improved load capacity, for example in slide bearings and similar components.
- Example 17 Determination of the sliding behavior by means of elastomer dynamic measurements:
- the conditions / measurement parameters are selected as follows: Elastomer material: 75 FKM 585; Pressure: 0.25 bar; Temperature: 70 ° C; Test duration: 240 h; 10 cycles with a speed of 2000 rpm (20h) and Orpm (4h); Greasing: Bremer & Leguil Cassida GTS 2.
- Example 3 GV 1; Example 15b: GV 2, in each case in comparison to Comparative Example 2) a reduction in the radial shaft sealing ring tread / wear width from 0.66 mm to 0.35 mm (Example 3) or 0.54 mm (Example 15b) and a reduction in the shaft run-in from 20 pm to 0 pm (Example 3) or 14 pm (Example 15b) compared to the basic formulation without slip improvers (Comparative Example 2) is achieved .
- the measurement results for comparative example 4 show, increasing the viscosity of the basic formulation (mPAO 150 / comparative example 4 compared to mPAO 65 / comparative example 2) does not, however, achieve any improvement.
- Example 18 Determination of the sliding behavior with elastomer as friction partner by means of DES (Dynamic Elastomer Screening):
- the tests are carried out with a "ring-disc tribometer" under further development of the structure described by Sommer M. and Haas W. ([1] Sommer, M., Haas, W. "A new approach on grease tribology in sealing technology: Influence of the thickener particles ", Tribology International (2016), 103, 574-583).
- FKM elastomer material is used as the test material.
- the counter body is a steel counter body
- the lubricant composition to be examined is observed on a ring-disc tribometer, as described in [1], at a constant speed of 1.5 m / s and a temperature of 60 ° C. with a line load of 0.90 N / mm in order to provoke a breakdown of the lubricating film and solid body contact in the event of poor lubricating film formation.
- the lubricant compositions according to the invention with slip improvers show a significantly quieter and lower course over time the coefficient of friction m, which means a stable lubricating film build-up and speaks for hydrodynamic lubrication.
- the basic formulation without slip improvers shows an unstable build-up of the lubricating film, which manifests itself in a strong fluctuation and a higher profile of the coefficient of friction. This speaks for, at least local, solid body contact and a pronounced stick-slip effect.
- the addition of the slip improver reduces wear on the elastomer body by 57% (example 2: GV 3), 50% (example 14, GV 1), 67% (example 11, GV 2) or 63% (Example 5, GV 5), and the wear on the steel counter body is reduced by 80% (Example 2: GV 3), 67% (Example 14: GV 1), 67% (Example 11 : GV 2) or 73% (Example 5: GV 5), in each case in comparison with the basic formulation without slip improvers (Comparative Example 3).
- micropitting resistance test stand PCS Instruments, London, UK. Micropittings describe damage to gear contacts.
- the test bench uses a triple configuration where a central roller is in contact with three disks, resulting in three roller contact cycles per roller revolution.
- the two lower discs are partially immersed in oil and transport it into contact during the test, which simulates splash lubrication.
- the roller and the disks are driven by separate motors, which allows the simulation of different slide-roll ratios (SRR).
- SRR slide-roll ratios
- the tests are performed at a Hertzian contact pressure of 1.7 GPa, an SRR of 20% to 30%, an oil temperature of 90 ° C and 10 million cycles.
- the coefficient of friction and vibration were recorded with a torque meter and an accelerometer, respectively, during the test.
- the test roller is cleaned using a solvent to remove residual oil and the weight of the roller is determined and the track track is taken with an optical microscope.
- the ability of a lubricant composition with regard to its resistance to micropitting is assessed by the weight loss (comparison of weight before and after measurement) of the roller (see FIG. 5A) and by changing the wear track width (see FIG. 5B).
