A bearing assembly for a turbo-engine with a bearing and parts of a bearing temperature detecting device. The bearing includes a main body having a thermoplastic bearing layer. A space is defined in the interior of the main body and of the thermoplastic bearing layer for accommodating parts of the bearing temperature detecting device. The space has a through hole having a first opening in the thermoplastic bearing layer and a second opening located in the main body. The parts include a temperature conducting element, a temperature sensor, and a securing fixture that attaches the temperature conducting element. The first opening of the through hole has a chamfer and the first end of temperature conducting element has a head which is correspondingly shaped to the chamfer in a form fitting manner. The center-axis of the temperature sensor extends transversely to the center-axis of the temperature conducting element.

Embodiments disclosed herein are directed to bearing assemblies, related bearing apparatuses, and related methods. An example of a bearing assembly disclosed herein may include a support structure having a first end and a second end. The bearing assembly also includes a superhard bearing element secured to the first end of the support structure. The superhard bearing element includes a superhard sealing surface that may be configured to contact a sealing surface of an opposing bearing element, a base surface contacting the support structure and opposing the superhard sealing surface, and at least one lateral surface extending between the superhard sealing surface and the base surface. The support structure and the superhard bearing element may both include at least one conduit extending therethrough through which a fluid may flow.

A motor assembly includes a shaft, a bearing, at least one fluid channel, a temperature sensor, a lubricant supply pump, and a controller. The bearing defines a bearing interface against which the shaft rotates. The at least one fluid channel is fluidly coupled with the bearing interface. The temperature sensor detects a temperature of the bearing. The lubricant supply pump is fluidly coupled with the at least one fluid channel to transport lubricant from a lubricant supply to the bearing interface via the at least one fluid channel. The controller receives the bearing temperature from the temperature sensor, determines a difference between the bearing temperature and a supply temperature of the lubricant, determines a lubricant flow rate based on the difference, and transmits a control signal to the lubricant supply pump to cause the lubricant supply pump to transport the lubricant to the bearing interface at the lubricant flow rate.

A hydrodynamic thrust bearing pad includes a composite laminate including at least one ply including a plurality of fibers oriented in at least one direction, and a bearing surface configured to confront a rotating thrust surface of a rotating shaft for transmitting axial thrust loads from the rotating shaft to the composite laminate. The bearing pad also includes a support surface configured to confront a stationary surface of a stationary housing for transmitting the axial thrust loads from the composite laminate to the stationary housing, and at least one side surface extending between the bearing and support surfaces. The at least one ply is configured to expand non-uniformly when heated from a first temperature to a second temperature for causing the composite laminate to warp from an unstressed state to a stressed state.

The present application provides a gearbox and an intelligent cleaning apparatus. The gearbox is used for the intelligent cleaning apparatus, and includes a rotatable part and a porous bearing. The rotatable part can rotate around a rotation axis to transmit power for a cleaning head of the intelligent cleaning apparatus, and has a contact surface. The porous bearing is fixedly arranged and has a support surface, and the support surface of the porous bearing is in contact with the contact surface of the rotatable part to support the rotatable part in rotating relative to the porous bearing. At least one of the contact surface and the support surface is provided with a recess.

Systems and methods related to hydrodynamic bearings are provided. One example hydrodynamic bearing system includes a sleeve assembly including a cross-member fluidically dividing a first interior cavity from a second interior cavity, a first shaft positioned in the first interior cavity, and a second shaft positioned in the second interior cavity. The hydrodynamic bearing system further includes a first journal bearing including a first fluid interface surrounding at least a portion of the first cantilever shaft and configured to support radial loads and a second journal bearing including a second fluid interface surrounding at least a portion of the second cantilever shaft and configured to support radial loads.
