Abstract: The present invention relates to a non-hydroxide grease composition comprising a base oil and a thickener which comprises amorphous hydrophilic silicon oxide particles and one or more metal salts of different organic acids, wherein the silicon oxide particles have a BET specific surface area of at least 50 m2/g and wherein the amount of the metal salt(s) is 4-25% by weight, based on the total weight of the grease composition. The present invention further relates to a method for manufacturing said grease composition and the use of said grease composition for lubricating a bearing and in couplings and gearings.

Abstract: A system for mounting an annular component on a shaft, comprising (a) a hydraulic nut having an annular coaxial cavity and a ring-like piston, displaceable within the cavity; (b) a displacement sensor for providing a displacement signal indicating the axial displacement of the piston within the cavity; (c) a wireless displacement transmitter for transmitting the displacement signal; (d) a pressure sensor for providing a pressure signal indicating a pressure within the cavity; (e) a wireless pressure transmitter for transmitting the pressure signal; (f) a pump arranged to pump fluid into the cavity; and (g) a remote control device having a communications device arranged to receive transmitted pressure and displacement signals, wherein the remote control device is arranged to output control information for controlling the pump.

Abstract: A kit for testing grease includes components for testing consistency, oil bleed characteristic and contamination. Consistency of the grease is tested by compressing a sample of the grease between two surfaces (e.g., glass plates), measuring the extent of spread, and comparing the measured spread to a calibrated reference. Oil bleed characteristic is tested by placing a quantity of the used grease on a test medium, heating the test sample, measuring a dimension of the grease quantity on the heated test sample, and determining the bleed characteristic of the used grease by comparing the dimension of the grease quantity to a reference. A contamination test may be performed by further compressing the consistency sample and inspecting the sample both by the naked eye and with a microscope.

Abstract: Improved induction heating of a rolling bearing without the risk of damaging or blocking the bearing is achieved by controlling the heating cycle as a function of the temperature difference between the inner and outer bearing rings and/or dividing the heating cycle into different portions using different power combinations of at least two induction coils.

Abstract: A hydraulic transmission device for a machine, including a declutchable hydraulic motor having radial pistons, and including a cam that is secured to a casing, and a cylinder block and an internal fluid distributor that are disposed in the casing; a hydraulic pump including a drive member; and fluid exchange couplings; in which device the casing and the distributor are mounted to rotate relative to a stationary support about an axis of rotation, whereas the cylinder block is fastened to said support.

Abstract: An electrically conductive physical object, e.g., a rolling-elements bearing, is inductively heated by using a first primary coil around a first core for inducing a first electrical current in the object; and a second primary coil around a second core, different from the first core, for inducing a second electrical current in the electrically conductive material. The first and second primary coils are electrically connected in parallel and the parallel connection is driven from a single switched-mode power supply.
