One embodiment of the present invention provides an actuator comprising: a housing having a mounting space part formed therein; a motor part provided inside the housing and generating power; a reduction gear part of which a plurality of gears respectively having an internal gear and an external gear sequentially engage with each other so as to transmit the power generated in the motor part; and a rod part engaging with the gear disposed at the last position, and linearly moving according to the rotation of the gear, wherein one of the plurality of gears is formed such that the internal gear and the external gear can rotate together or rotate independently.

A driving force transmission mechanism includes a first transmission member and a second transmission member that are arranged on an identical rotational center axis. The first transmission member includes one or more transmission claws engaged with the second transmission member. The transmission claw includes, at a position away from the rotational center axis, a fixing portion with respect to the first transmission member, and extends in a direction crossing a direction directed from the fixing portion to the rotational center axis. The second transmission member includes one or more stoppers engaged with a tip end of the transmission claw and one or more holding portions engaged with a side of the transmission claw, which faces the rotational center axis.

A transaxle according to the present application may include: a transaxle case; an input member supported within the transaxle case; a gear drivingly connected to the input member within the transaxle case; an output member which is supported within the transaxle case and arranged at the inner peripheral side of the gear concentrically with the gear; a cage with a roller as a bidirectional overrunning clutch interposed between the inner periphery of the gear and the outer periphery of the output member within the transaxle case; and a drag mechanism provided within the transaxle case to apply rotational resistance to the cage to make the bidirectional overrunning clutch be engaged. The cage has a first end and a second end, which oppose each other in an axial direction of the output member. The first end of the cage is close to a first bearing which pivotally supports the output member to the transaxle case. The drag mechanism has a rotation member which is locked to the cage at the first end of the cage so as to be relatively non-rotatable, and a spring member for applying the rotational resistance to the rotation member.

A rotating mechanism includes a stationary component and a rotating component rotatablely connected to the stationary component. One of the stationary component and the rotating component is provided with at least one group of clamping grooves each including a plurality of clamping grooves that are consecutively arranged in a rotation direction of the rotating component. The rotating mechanism further includes at least one elastic clamping block, which is in one-to-one correspondence with the at least one group of clamping grooves, disposed on another one of the stationary component and the rotating component. Each elastic clamping block is configured to be capable of being matched with any clamping groove of a plurality of clamping grooves included in a corresponding group of clamping grooves, and to be capable of being elastically deformed in a direction away from the clamping groove under a squeezing action of an inner surface of the clamping groove.

A handle connectable to a screw-type mechanical drive component for transmitting to the latter a first torque comprises first connection means, defining a constraint axis, for the connection of the handle to the mechanical drive component, a ring nut to which a second torque is manually applicable, support means of the ring nut for rotatably supporting the latter around an axis of rotation coinciding, in use, with the constraint axis, second means for connecting the ring nut to the support means, for connecting/disconnecting the ring nut and the support means in a mechanical and selective way, so that the ring nut is kinematically connected to the support means when rotated around the axis of rotation with a second torque lower than a threshold value and kinematically disconnected from the same upon exceeding such a threshold value.

Torque limiting connectors are described herein. A torque limiting connector includes an outer connector, and inner connector, and a clutch. The outer connector includes a profile disposed on an inner surface of the outer connector. The inner connector may be disposed within the outer connector and can include an upper threaded portion and a lower threaded portion. The clutch can be disposed around and rotationally coupled to the inner connector and can include a plurality of clutch teeth extending from an outer surface of the clutch, wherein the plurality of clutch teeth are outwardly biased to be releasably engaged with the profile of the outer connector. The plurality of clutch teeth can be configured to transfer torque from the outer connector to the inner connector when the torque is below a torque limit, and prevent transfer of torque when the torque exceeds the torque limit.

We disclose a novel family of mechanical bi-directional speed sensing clutches that use Reactive Intermediate Elements with interlocking wedging ramps, in a first element, corresponding to similarly shaped interlocking wedging ramps in a second element. Such that when said first and second elements are counter-rotated compression or expansion occurs to provide torque-transfer.

A shaft interlock system may have an a interlocking piston that translates a movable locking apparatus configured to interface with a turbine shaft having a fixed locking apparatus. The movable locking apparatus may engage and disengage the fixed locking apparatus. When the movable locking apparatus is engaged with the fixed locking apparatus, the turbine shaft is only able to turn in one direction. When the movable locking apparatus is disengaged from the fixed locking apparatus, the turbine shaft is able to turn in both directions. In this way, a turbine shaft can be prevented from reverse rotation.

An operating system for an architectural covering is provided. The operating system allows at least three modes of operation of an architectural covering. A transmission may be included between an input assembly and an output drive member, and the transmission may be selectively engaged to place the operating system into one of the at least three modes of operation. The operating system may include a first drive section including an input, a second drive section including an output, and a control mechanism arranged to selectively lock an element of the first and second drive sections to control movement of the output of the operating system upon actuation of the input. A shift lock is also disclosed herein. In use, the shift lock operates to restrict shifting operation of the operating system from one operating mode to another.

A transmission shaft automatic connection and disengagement device and test equipment. An input shaft drives a transmission shaft to rotate through a second connection shaft, a ratchet assembly, a first connection shaft and an output shaft so as to apply an acceleration torque, gears of the input shaft and the first connection shaft can be completely engaged and completely separated through extension and retraction of piston rods of a first group of air cylinders and a second group of air cylinders so as to achieve an effect that when a driving shaft needs to perform driving, a power system gets involved, and after driving is completed, the power system is cut off, and through the ratchet assembly, the transmission shaft can be prevented from driving a motor to work in reverse.
