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.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus can comprise a generator, a hardware controller, a capacitor, and a battery. The controller can control whether the capacitor is electrically coupled with the battery based on one or more conditions. The controller can control whether the generator is electrically coupled with the capacitor and/or the battery.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass, a generator, a charger, a hardware controller, and a communication circuit. The driven mass rotates in response to a kinetic energy of the vehicle and is coupled to a shaft such that rotation of the driven mass causes the shaft to rotate. The driven mass exists in one of (1) an extended position and (2) a retracted position. The generator generates an electrical output based on a mechanical input coupled to the shaft such that rotation of the shaft causes the mechanical input to rotate. The charger is electrically coupled to the generator and: receives the electrical output, generates a charge output based on the electrical output, and conveys the charge output to the vehicle. The controller controls whether the driven mass is in the extended position or the retracted position in response to a signal received from the communication circuit.

The bearing has a housing and a plurality of pads coupled with the housing. The pads form bearing surfaces facing a shaft receiving space. The pads are provided with cooling micro-channels formed therein, adapted to circulate lubrication fluid and improve heat removal.
