Definitions

  • Lubricating composition process for its preparation, use in a rolling bearing and rolling bearing with this.
  • the invention relates to a lubricant composition, a process for their preparation, a roller bearing with the lubricant composition and a use of the lubricant composition for a Wälzla- ger, wherein the lubricant of a lubricating oil component and a thickening component is formed.
  • lubricating compositions in mechanical engineering elements primarily serve to reduce friction moments in the case of components moving relative to one another and preferably forming a metallic friction.
  • different compositions of lubricants are proposed.
  • DE 696 27 872 T2 discloses a lubricant composition in which, in particular for lubricated metalworking, a superabsorber is added to a lubricant which is intended to absorb water on a large scale.
  • Such lubricant compositions are not suitable for use with rolling contacts.
  • a lubricant composition for rolling and plain bearings is known in which ionic liquids are added to a lubricating oil to improve the lubricating properties, in particular against thermal and oxidative attack. Due to the rapid relative movements of machine elements against each other, in particular of rolling bearing components in rolling bearings such as the rolling elements on bearing guides, on the one hand occur in the case of grease high churning losses, which can lead to increase friction between two components moving against each other. On the other hand, lubricating oils are volatile, in particular under the influence of centrifugal force on rotating parts such as races of rolling bearings, so that the lubricating effect subsides.
  • the object of the invention is therefore to propose a lubricant composition which reduces the frictional torque of components moving against one another, in particular rolling elements in rolling bearings. Furthermore, a method for producing such lubricant compositions and a rolling bearing with reduced frictional torque should be proposed.
  • a lubricant composition in particular in a rolling bearing with a lubricating oil component and a viscosity of this increasing thickener component, wherein the thickener component is formed from a mixture of an ionic liquid and a superabsorbent.
  • a lubricant concept can be created that allows variable composition over a widely adjustable and variable range of parameters lubricant in particular for the requirements in rolling bearings with the same components and only with respect to the mass fraction of the thickener.
  • the properties are variable over a wide range of applications, for example, the viscosity of a lubricating oil used as the basis can be systematically lowered, so that at As a proportion of the thickener component, a consistency of the lubricating oil composition which is gel-like can be achieved.
  • such a gel-like lubricant composition may also have the influence of centrifugal force or other advantageous properties of greases with respect to a structure of a lubricating film on the rolling components, whereby the frictional moments of the rolling points may be reduced in a manner previously achieved only by lubricating oils.
  • a lubricating oil component mineral synthetic and natural oils and mixtures thereof can be used.
  • additives and additives known in the art such as, for example, inorganic materials such as molybdenum sulfide, graphite and the like, can be added to the lubricant composition. With regard to their proportions, these are added in the following with ratios of the lubricant component.
  • the lubricating composition has particularly advantageous properties for lubricating engine components when the lubricating oil component and thickener component are mixed together in a mass ratio between 5: 1 and 1: 5.
  • the adaptation of the properties to the application by the selection of components - lubricating oil component, ionic liquid and superabsorber - and their specific properties and by the ratio of the components to each other.
  • a mass ratio of the lubricating oil component to the thickener component between 3: 1 and 1: 1 has proven to be particularly advantageous.
  • the variation of the mass ratios depends on the desired viscosity, taking into account the properties of the individual components of the lubricant component and the thickener component used and the material costs.
  • a cost-reducing addition of high-quality Components of the thickener components with a low proportion prove to be advantageous if this can reduce the cost of the lubricant component used with a larger proportion and vice versa.
  • the superabsorber for example Luquasorb®
  • a polymer matrix for example from polyacrylic acid, polyacrylamide, polacrylonitrile, polyacrylic esters and the like, and mixtures thereof, copolymers, graft copolymers, which are prepared by only partially neutralized functional groups and / or by introduction and immobilization Of ions such as sodium, potassium, ammonium, chloride, bromide ions and the like and / or organic cat- or anions carry partial charges, so that ions and dipolar substances such as water are absorbed in a multiple amount of the self-weight of the superabsorbent. Taking advantage of this absorption effect, the ionic liquid is absorbed and thus produced the thickener component according to the invention.
  • the absorption complex formed in this way the thickener component can fulfill different functions.
  • the absorption complex itself can positively influence the properties of the lubricant composition, for example by increasing the viscosity of the lubricating oil.
  • the depot effect of the absorption complex for the ionic liquid can show advantageous effects. For example, if the proportion of the ionic liquid is adjusted so that free ionic liquid is present in equilibrium, the absorption complex buffers this portion if the ionic liquid is lost, for example by destruction.
  • the absorption complex and the superabsorbent itself can be active as active constituents of the thickener component, with perabsorber additionally existing, interfering water, for example, in a water ingress can absorb into the rolling bearing and thus seizure of the bearing components is effectively avoided in itself by the water-dissolving lubricant film.
  • the ionic liquid is formed from a cationic and an anionic component, with both components or the cationic or anionic component being active with respect to the lubricating properties of the lubricant composition.
  • the active components may contain organic radicals which form lubricating properties or increase the viscosity of the lubricant component alone or in conjunction with the superabsorbent.
  • Corresponding compounds which can preferably be dissolved in the lubricant without disadvantages can be provided as counterions.
  • organic cations of hydrochlorides and the like or organic anions with functional acid residues can be provided.
  • the ionic liquids are with respect to their melting point designed so that they are liquid at temperatures below 100 ° C, preferably at room temperature. Examples which may be mentioned of examples of ionic liquid are 1-decyl-3-methylimidazolium-tetracyanoborate and 1-ethyl-3-methylimidazolium-dimethylphosphate in non-exhaustive list.
  • the object is further achieved by a method for producing the described lubricant composition, wherein a predetermined mass of an ionic liquid is absorbed to form a thickening component of a given mass of a superabsorber and a predetermined mass of the thickening component under temperature supply with a predetermined mass of a lubricating oil component a gel-like mass is homogenized.
  • the mass ratio between ionic liquid and superabsorber is set to the equilibrium state, in which the maximum absorption capacity of the ionic liquid is achieved, for example under production conditions, at maximum or minimum operating temperature at the superabsorber.
  • the Superabsorbent are metered in excess, wherein during the production or during operation of a rolling bearing with the lubricant composition corresponding water is absorbed by the superabsorber in addition to the ionic liquid and thus a substantially active water-free lubricant composition can be achieved.
  • the ionic liquid may be provided with improved lubricating properties, thereby shifting the lubricating properties of the superabsorbent to the background. Dosing of the ionic liquid takes place in excess and the function of the superabsorbent is limited to an increase in the viscosity of a depot effect for the ionic liquid.
  • the object is further achieved by a use of the lubricant composition as a lubricant for a rolling bearing.
  • a suitable viscosity in particular a gel-like consistency
  • advantages are achieved in reducing the frictional torque of rolling bearings, which hitherto have only been achieved by lubricating oils.
