Latest Patents

Ichimura's latest patents include innovative designs for tilting-pad-type journal bearings. The first patent describes a tilting-pad-type journal bearing that consists of a rotary shaft, multiple tilting pads, a housing, a fixing structure, an oil inlet, and side plates. The tilting pads are designed to support the rotary shaft in a radial direction, while the housing accommodates these pads. The fixing structure maintains a circumferential relative position with respect to the housing, allowing the pads to swing freely. The oil inlet is responsible for supplying lubricating oil between the tilting pads and the rotary shaft, ensuring smooth operation.

The second patent focuses on a tilting pad journal bearing that features a unique arrangement of oil feeding holes. This design allows the circumferential position of the oil feeding hole to vary depending on the position of each bearing pad. For instance, the opening portion of the oil feeding hole for the bearing pad under the rotary shaft is set toward the upstream side in the rotating direction, while the pad above the shaft is set toward the downstream side. This innovative approach enhances the efficiency and performance of rotary machines.
