摘要： A footwear system can employ a brake and/or a clutch, such as a one-way clutch, to convert human motion into usable electricity. The brake and one-way clutch can be used together, such as on opposite ends of a spring. During a storage phase, the brake can be engaged and the one-way clutch disengaged so the spring stores an energy. After the storage phase, the brake can be removed to initiate the release phase since the brake is not stopping the spring, but the one-way clutch allows the stored energy to be released.

摘要： A gearhead for a handheld power tool for machining workpieces, having a housing in which an output that can be connected to a drive of a handheld power tool is accommodated, and also having a tool shaft to which a tool can be coupled, wherein a braking device that can be moved between a braking position and a release position and that acts upon the tool shaft is provided for braking of the tool shaft. A switching device is provided that can be moved between a first switching position, in which the tool shaft is connected to the output in a power transmitting manner and in which the braking device is transferred into the release position, and a second switching position, in which the tool shaft is decoupled from the output and in which the braking device is transferred into the braking position.

摘要： A variable-speed speed-up mechanism (1) includes an electric device (50) and a transmission device (10). In the transmission (10), an internal gear carrier shaft (37) forms a constant-speed input shaft (Ac), and a planetary gear carrier shaft (27) forms a variable-speed input shaft (Av). The electric device (50) includes a constant-speed electric motor (51) having a constant-speed rotor (52) which is configured to rotate the constant-speed input shaft (Ac), and a variable-speed electric motor (71) having a variable-speed rotor (72) which is connected to the variable-speed input shaft (Ac). The variable-speed speed-up mechanism (1) further includes a brake mechanism (200) which is configured to detect an abnormal state of the variable-speed electric motor (71), stop the rotation of at least one of the variable-speed input shaft (Ac) and the variable-speed rotor (72), and continue the rotation of the constant-speed rotor (52).

摘要： A first planetary gear set includes a first sun gear to which power is input from a hydraulic motor. The first planetary gear set includes a first carrier and a first ring gear. The first carrier and the first ring gear are able to rotate in conjunction with rotation of the first sun gear. A second planetary gear set includes a second sun gear configured so as to rotate integrally with the first carrier. A hydraulic clutch mechanism allows or prohibits the rotation of the first ring gear.

摘要： A door curtain anti-dropping device for a rolling door is provided. The device comprises a worm shaft connected to the output shaft of the door operator, and a drive shaft comprising a limiting disc with through holes. The worm wheel having receiving slots is fixed on the drive shaft to mesh with the worm. The driven wheel is disposed adjacent to the limiting disc. Baffle plates designed to cover the through holes and receiving slots extend from the driven wheel. Plural latching pins stored with spring potential energy are compressed by the baffle plates and retained in the through holes and receiving slots. When the worm wheel is excessively worn and dislocated from the driven wheel, the baffle plates are moved to allow the latching pins to spring out and insert into the notches of the front cover, thereby lock the worm wheel and prevent the winding shaft from rotating.
