摘要： Devices, systems, and methods for varying rotational speeds is disclosed. A battery pack has a plurality of batteries and a switch. The battery pack has an overall voltage. The switch varies the overall voltage in discrete steps by combining the plurality of batteries in series, in parallel, or in a combination thereof. A motor drives a shaft at a rotational speed. The motor is powered by the battery pack. The rotational speed varies proportionally with the overall voltage.

摘要： A winch is described that includes a drum, a motor and transmission, and a tensioner. The motor and transmission apply torque to the drum, thereby enabling the drum to draw in and let out a line. The tensioner is positioned adjacent to the drum, such that when the line passes between the tensioner and drum, the line is in frictional contact with the tensioner and drum. The tensioner rotates with a linear speed exceeding a linear speed of the drum as the line is let out from the drum, and rotates freely as the line is drawn onto the drum. Methods for making and using the winch are also described.

摘要： Embodiments of a two-way output reverse-torque clutch described herein may include a torque input having a segmented race, a pin removably disposed adjacent to, and between, at least two segmented race segments, a torque output rotatably disposed within the segmented race, and an outer race encircling the segmented race. The torque output may include a cam surface with an interference point corresponding to at least one of the one or more pins. The cam surface may have an interference point. The outer race may be in slideable contact with the segmented race. A torque exerted directly on the output may force the interference point against the pin, wedging the pin between the interference point and the outer race and preventing torque from being transmitted to the input from the output. The clutch may prevent torque from being transmitted to the torque input from the torque output with one pin.

摘要： An apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. In certain embodiments, a depth of the groove is equal to or greater than a radius of the line. In the same or other embodiments, a passive guide that physically engages and tracks the groove may be used to guide the line into the groove.

摘要： An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. The transmission includes at least one stage of gearing to reduce a gear ratio of the motor relative to the drum. A shaft couples the motor to the transmission and a locking mechanism selectively locks the shaft to prevent rotation of the drum. In certain embodiments, a braking mechanism may be provided in addition to the locking mechanism to slow the motor when the motor is not applying torque to the drum. This may slow the motor sufficiently to enable engagement of the locking mechanism.

摘要： A method of powering an intermittent-duty cycle winch is disclosed. The method includes identifying a number of amp-hours required to power the winch through one duty cycle, identifying a minimum required rest period between two consecutive duty cycles, and assembling a power supply unit that powers the winch based, at least in part, on the duty cycle and the rest period. The duty cycle is mechanically or thermally limited. The power supply unit includes at least two components: a power storage unit and a charging unit that recharges the power storage unit during the rest periods. The power storage unit powers the winch through at least one duty cycle. The charging unit recharges the power storage unit during the rest period so that the power storage can power the winch through at least a second duty cycle that immediately follows the end of the minimum required rest period.
