Introduction

Fridtjof Bremer is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of dynamic bearing technology, holding 2 patents that showcase his innovative approach to engineering solutions.

Latest Patents

One of Bremer's latest patents is for a dynamic groove bearing comprising a porous lubricant reservoir. This invention relates to a dynamic groove bearing that includes an internal and external bearing part, which rotate relative to each other about an axis of rotation. The bearing surface of one part features two grooves that cooperate with the bearing surface of the other part. A reservoir made from a porous material is positioned between the bearing surfaces, ensuring a uniform supply of lubricant to the groove patterns while minimizing the number of parts in the groove bearing. A preferred embodiment includes a ring-shaped body made from porous material, which is mounted in the external bearing part and may contain air-vent ducts. This dynamic groove bearing can be utilized in electric motors for driving rotatable supports in scanning devices, such as optical disc players.

Another significant patent by Bremer is for a hydrodynamic spiral-grooved journal bearing for electromagnetically driven free-piston Stirling machines. This invention features a piston that can both reciprocate and rotate within a cylinder, supported by a grooved dynamic bearing. The design ensures that the piston remains free of radial dynamic instability during operation by carefully selecting the length of the sealing surface and the size of the gap between the sealing surface and the cylinder wall.
