摘要： The present invention is directed to a self-locking non-backdrivable gear system. The gear system may comprise a primary motor input and self-lubricating gear box. The primary motor input is for rotation of the gearbox about the axis of a drive shaft. The gearbox may comprise an input ring gear, one or more planet locking gears, fixed spur gear, and output spur gear. In operation, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the planet locking gear which causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, a rotational force applied to the output spur gear causes the gear teeth on the fixed and output spur gears to lock the planet gear in place.

摘要： The present disclosure discloses a double-speed electric winch and an operating method of the winch. The winch comprises two groups of planetary gears with different transmission ratios in a gearbox. The two groups of planetary gears have corresponding outer ring gears. The gearbox has a rotatable handle which has a locking head inserted in the gearbox. As the handle rotates, the locking head engages with the outer ring gears in different manners to provide a first rotating speed mode, a second rotating speed mode, and a disengaged mode.

摘要： A line puller designed to accept a Working line (15) through a Working Line Fairlead (14), directing the line around a Capstan (21), and through a brake (28). This line puller is mainly driven by gears or friction rotational devices (38), driving the internal face or cogs (36) of a Capstan. The design allows users to load a Working Line (15) from midsection not requiring the end of the line to load the puller. The puller can be hard mounted or Soft mounted using an Anchor Line (44) fed through incorporated Anchor Fairleads (20). Multiple gear rations allow users to pull objects at different rates.

摘要： A multi-speed winch is attached to a motor vehicle and is hydraulically powered by the vehicle's power steering system or other hydraulic source innate to the host vehicle. The winch operates in either a low-speed, high-torque mode for moving heavy loads, a high-speed, low-torque mode for quickly releasing or retrieving cable, a free-spooling mode for manually releasing cable, and a brake mode for holding the cable and load at a fixed position. The high-speed mode is enabled by coupling the drive shaft directly to the winch drum. The low-speed mode is enabled by coupling the drive shaft to the winch drum through a planetary gear assembly. In an alternate embodiment, high-speed mode is enabled by coupling the drive shaft to the winch drum through one of two planetary gear assemblies. Free-spooling mode is achieved by disengaging the drive shaft from the winch drum, and brake mode is achieved by engaging both the direct drive coupling and the sun and planet gear arrangement. The four operational modes are selected by four different combinations of positions of a direct drive selector handle (which determines the position of the coupling plate) and a gear reduction handle (which determines the position of the locking pin). In an alternative embodiment, the four operational modes are selected by four different combinations of positions of a direct drive solenoid and a gear reduction solenoid. A four-way, dual solenoid-operated valve controls the flow of pressurized hydraulic fluid to the winch motor.
