Provided is an actuator having a double-gear structure for an electromechanical parking brake. The actuator includes: a main housing having a motor seat and a gear seat; a motor assembly disposed in the motor seat and providing torque; and a gear assembly rotated by the torque from the motor assembly and performing a reduction function through a plurality of gears.

A control drum system for a nuclear reactor including a reactor core, including an ex-core reflector including a plurality of cylindrical apertures, a plurality of control drum assemblies, each control drum assembly including a drive shaft, a drum cylinder affixed to a bottom end of the drive shaft, and a planetary gear attached to a top end of the drive shaft, wherein each drum cylinder is rotatably received in a cylindrical aperture, a first control drum drive motor operably connected to a first control drum assembly, and an annular ring gear that is operably connected to the planetary gear of each of the control drum assemblies so that all the control drum assemblies rotate simultaneously.

This invention provides an electric screwdriver with an integrated torque adjustment and sensing function, comprising a torque sensor connected between an electric motor and a torque adjuster. The torque sensor comprises a transmission shaft connected to the motor shaft by the shaft, a torque sensing component and at least one planetary gear set. The planetary gear set has a torque output component. The transmission shaft transmits the speed reduced rotational force through the torque output component to drive the output shaft to output a target torque which can be adjusted by the adjuster. The torque sensing component senses the operating torque between the transmission shaft and the torque output component of the torque sensor, thereby assembling to improve the problem that the conventional electric screwdriver can only adjust but cannot accurately sense the operating torque.

A joined component includes a first member provided with a first joint surface having an arranging part where a brazing filler material is arranged, a second member joined to the first member by brazing, and provided with a second joint surface having an accommodating recess that opposes the arranging part, a guide groove formed in the first joint surface or the second joint surface, and extending from the arranging part or the accommodating recess toward a fringe of the first joint surface or the second joint surface, and a chamfer formed along the fringe of the first joint surface or the second joint surface, and the guide groove communicates to the chamfer.

A buffer gear set mounted between a motor and a transmission assembly of a power tool is disclosed to include an outer ring seat and an inner ring seat coaxially arranged together, a planetary gear set mounted in the outer ring seat, accommodation spaces defined between the outer ring seat and the inner ring seat, and buffer members respectively accommodated in the accommodation spaces. When an external force is applied between the outer ring seat and the inner ring seat, the buffer members absorb a part of the external force transmitted between the outer ring seat and the inner ring seat, thereby reducing the impact of the overall power tool, achieving shock absorption, reducing noise and improving work efficiency and quality.

A commercial vehicle includes at least one driven axle, a service brake, at least one propulsion engine, and wheels. A parking brake function of the vehicle is achieved by a bistable locking means that acts on both wheels. A first and second multi-speed gearbox having respective first and second gear stages are each activated by an actuator and coupled to the wheels. The parking brake function is achieved at least in-part by concurrently activating the first and second gear stages. A computing device is configured to activate the bistable locking means when the commercial vehicle is at a standstill and configured to send a brake request via an electronic signal to an electronic brake control unit to activate the service brake.
