摘要： 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.

摘要： A bearing housing is provided with a cooling channel in at least part of the circumference around the bearing. The cooling channel is provided with a flow guide member at least in part of its flow section to construct a tortuous passage whose flow distance is longer than the corresponding circumferential length of the flow section. On the basis of the above-mentioned bearing housing, the present invention also provides a bearing housing unit, a continuous casting roll line and a continuous casting machine that use the bearing housing. The above-mentioned bearing housing adopts an optimized cooling channel design, which can obtain a better cooling effect without changing other structures of the bearing housing. Therefore, it is particularly suitable for upgrading existing equipment and has a huge cost advantage and a wide range of application prospects.

摘要： A device lubricates a connecting rod bearing on a crankshaft of an internal combustion engine. The device has a piston having an internal piston cooling fluid channel, and an outlet channel in fluid communication with the fluid channel. The device has a connecting rod, which is connected to the piston in an articulated, in particular pivotable, manner, and has a large connecting rod eye and a connecting channel. The large connecting rod eye is formed for receiving the connecting rod bearing. The connecting channel forms a fluid connection between the outlet channel and the large connecting rod eye so that a fluid, in particular a cooling lubricating fluid (e.g. oil), can be fed, or is fed, from the fluid channel to the large connecting rod eye via the outlet channel and the connecting channel. The connecting rod bearing can be lubricated by cooling oil from the fluid channel of the piston.

摘要： Improved bearing roller elements are disclosed. A first disclosed improvement is the addition of vanes to a ring-roller type element which allows fluids (such as liquids or gases) to flow through the bearing assembly. The fluids can then provide convection cooling. With proper configuration, the use of such vaned ring-roller elements can even allow the creation of a pump, either as part of the larger apparatus' cooling system or as a dedicated device. A second disclosed improvement, which can be used in combination with the first or in isolation, is the use of magnetic spokes in ring-roller type elements which allows them to be driven by an electromagnetic field. The use of such magnetic elements in the bearing roller elements also allows electromagnetic braking and/or regenerative braking.A bearing assembly incorporating the roller elements in a ring configuration and using pre-load to produce additional benefits is also disclosed.

摘要： A device for injecting a fluid into a mechanical system that may undergo heating, comprising at least one body containing a thermally triggered charge generating combustion gas, ignition of the charge being able to be triggered under the action of an ignition command and/or under the effect of a heat contribution, from a heating area of the body toward the charge, a reservoir containing the fluid, means for fastening the device to the mechanical system, the fastening means adapted to put the reservoir in fluid communication with the mechanical system, and means for delivering pressurized fluid outside the reservoir through the action, directly or through intermediate means, of the combustion gases. Within the device, the fastening means comprise at least one injection sleeve provided with an outer thread coated with an anti-loosening adhesive film. The invention also relates to a mechanical system equipped with at least one such device.
