Definitions

  • the invention relates to lubricating greases on calcium / lithium complex soap base, the use of greases for encapsulated constant velocity joints and constant velocity joints provided with such a grease and a method for producing the greases.
  • Lubricants For tribosystems, especially those used in many technical applications, it is important to use lubricants to reduce friction and wear on the contact surfaces of moving parts. Depending on the application, lubricants of different consistency can be used. Lubricating oils have a fluid and flowable consistency, while greases have a semi-solid to solid - often gelatinous - consistency.
  • a characteristic of a lubricating grease is that a liquid oil component is absorbed and retained by a thickener component.
  • Greases generally consist of a thickening agent which is homogeneously distributed in a base oil. Frequently, additional auxiliaries, such as emulsifiers, are used so that the thickener is stably dispersed in the base oil. Various substances are known as base oils.
  • the thickeners used are organic and inorganic compounds.
  • a lubricating grease The most important rheological properties of a lubricating grease include the consistency or its yield point, the avoidance of post-hardening and excessive oil separation under thermal and mechanical stress and a stable viscosity-temperature behavior. Often, even with lubricating grease outlet sealed lubrication points, a thixotropic (shear thinning) and shear unstable behavior of the grease advantageous as long as a consistent grease is required only for the assembly of appropriate components. In order to create a grease of high utility value depending on the lubrication and equipment requirements, a high degree of practical experience is required.
  • Greases are often used in sealed or sealed environments to protect the lubrication point from water, to minimize grease losses, and to prevent the ingress of particles such as sand or dust.
  • a typical application is greased and plastic bellows sealed joints of constant velocity universal joint shafts.
  • the capsule material often makes the movements of the mutually moving parts or at least absorbs vibrations. This requires mobility and, in most cases, elasticity of the material, which must not be adversely affected by contact or interaction with the grease.
  • conventional greases attack these capsule materials, causing them, e.g. become brittle and / or damaged by hydrolytic degradation.
  • a disadvantage of the prior art is considered that most lithium or lithium complex fats, as well as most lithium / calcium fats have too high shear stability, with the result of increased flexing and thereby caused increased steady-state temperatures in the joint.
  • Object of the present invention is it u.a. to minimize the disadvantages described above in terms of bellows compatibility and the loss of efficiency and service life in drive shafts.
  • the object is solved by the subject matter of the independent claims. Preferred embodiments are subject of the dependent claims or described below.
  • the calcium / lithium complex soaps (Ca / Li complex soaps) of the present invention having a high calcium content exhibit unexpectedly good properties when used as a constant velocity joint grease.
  • Such products differ significantly from conventional Li / Ca fats.
  • Preference is given to preparing the Ca / Li soaps or the Ca / Li complex soaps in situ using the corresponding carboxylic acid compounds and not by mixing separately prepared Ca and Li soaps or Ca and Li complex soaps.
  • the calcium hydroxide present in excess in conjunction with the Ca / Li complex fat buffers the acidic aging products without significant alkaline hydrolysis of the ester groups of the thermoplastic elastomer due to the comparatively low alkalinity and dissociation of calcium hydroxide.
  • the Ca / Li complex fats are preferably to be prepared in such a way that the amount of lithium compound and calcium compound required for the reaction is dimensioned to ensure that the more reactive lithium compound (presently preferably LiOH) reacted as completely as possible with the carboxyl groups of the carboxylic acids used and the remaining, with the lithium compound unreacted carboxyl groups quasi in excess with calcium compounds (in the present case preferably Ca (OH) 2 ) are reacted.
  • the calcium soaps present in excess should lead to a reduced mechanical stability or lower yield point after the entry of the cardan shafts and thus to an improved supply of the friction points in the constant velocity joints.
  • the product formulation includes an additional complexing agent.
  • the composition according to the invention is therefore referred to as Ca / Li complex fat or Ca / Li complex soap fat and not as Ca / Li fat or Ca / Li soap fat.
  • the percentages by weight are based on the total composition and apply in each case independently of one another.
  • a constituent assigned to one of the groups a), b) c) or d) can not simultaneously be part of another group a) to d).
  • composition is further characterized by a calcium / lithium molar ratio of greater than 1.0 to 5.0 to 1, preferably 1.2 to 3.0 to 1, and more preferably 1.4 to 2.4 to 1, wherein the ratio is determined by all the calcium and lithium compounds present, ie it is, for example, the existing Ca (OH) 2 includes.
  • the thickener is used in such a way that the composition contains so much thickening agent that a cone penetration value (walk penetration) of 265 to 385 mm / 10 (at 25 ° C.), preferably 285 to 355 mm / 10, is obtained (determined according to DIN ISO 2137 or ASTM D 0217-97).

  • a grease according to the present invention is preferably, but not exclusively, used for the lubrication of constant velocity joints (constant velocity joint CVJ), as used for example in drive shafts for motor vehicles and machines.
  • the task of a constant velocity joint is the uniform transmission of torque from a shaft to an angularly mounted second shaft at diffraction angles of up to 50 °.
  • constant velocity joints are used in particular in front-wheel drive and all-wheel drive vehicles and generally divided into two groups: constant velocity fixed joints and constant velocity sliding joints.
  • the group of constant velocity joints includes Ball Joints (BJ) and constant velocity joints ("Undercut Free" UJ).
  • the group of constant velocity joints are Tripod Joints (TJ), Double Offset Joints (DOJ) and Cross Groove Joints (Cross Groove Joins LJ).
  • synchronized sliding joints not only ensure uniform torque transmission at different bend angles, but also provide length compensation for the drive shaft connecting the gearbox to the wheel.
  • the production of greases can be done as follows, for example: Mixing the salt / metal compound into the carboxylic acid compound which may optionally be extended with the base oil component, and optionally simultaneously heating the mixture to a temperature above 70 ° C to form a thickened grease product, cooling the grease product and optionally adding water, Shearing forces on the mixture, eg with a tooth colloid mill, a high pressure homogenizer and / or a three roll mill.
  • a vessel is charged with a stirrer in a first step at a speed of 0 to 150 U / min with 3 to 40% by weight of the educt components of the thickener and 20 to 90% by weight of the base oil, based on the total weight of the finished grease composition.
  • the thickener is synthesized in situ in the base oil, preferably under pressure and at elevated temperature in a closed reaction vessel, such as an autoclave.
  • Preparation Example A to C (Comparative Example)
  • the preparations of the example formulations AC are based on known and customary processes for preparing corresponding thickeners.
  • Production description Example E In a reactor, 1240 g of 12-hydroxystearic acid (12-HSA) and 560 g of sebacic acid were placed in 12,000 g of a base oil mixture and heated with stirring until the 12-HSA was melted. In the next step, 125 g LiOH and 295 g Ca (OH) 2 were added. The Ca (OH) 2 was dissolved in 300g of water prior to addition to the reactor. The batch was heated in a predetermined temperature program to the intended maximum process temperature with stirring. In the cooling phase, additives were added to the batch at certain temperatures. After adjusting the batch to the desired consistency by adding 5,400 g of the base oil mixture, the final product was homogenized by tooth colloid mill.
  • Example D and G The preparation of the example formulations was carried out analogously to the example formulation E with modification of the LiOH and Ca (OH) 2 amounts.
