    Abstract: An output torque sensing and limiting mechanism, for preventing the continued application of torque to a load when the torque exceeds a selected value. The mechanism is positioned at the end of a gear train, meshed with the final gear and adapted to transmit the output torque to the load, through an output adapter. An input gear assembly includes a sector gear, meshed with the gear train, for receiving the input torque. A housing assembly is rotationally carried on the input gear assembly, with wing members extending to define a wing angle. The sector gear lies in the wing angle, with vertical gear ends adjacent each wing member. A torque sensor subassembly is carried in each wing member, consisting of a bearing button positioned in registration with the sector gear end, biased into position by a wave spring and adjustable by means of a retainer button. Microswitches are carried on the sector gear, located with the switch elements extending into the gap between the sector gear and each wing member. If the torque applied to the sector gear exceeds the resistance of the wave spring, the bearing button deflects and the wing member makes contact with the switch element, which in turn removes power from the gear train.

Ramp surfaces (11a, 11b, 12a, 12b, 10a, 10b) are provided at the respective pockets to enable the ball members (13, 14) to ride out of the pockets upon an occurrence of an excessive torque thereby axially displacing the respective ramp members (10, 11) against a bias of springs (15, 16) coupled to the sun gears (8, 9) through planet gear radial support members (4) integrally formed with the sun gears (8, 9) thereby disconnecting a torque path through the actuator (1). Axial support for the radial support members (4) and ramp members (10, 11) is provided by struts (17, 18) fashioned as pins displaceable between an axial position and a transverse position upon the occurrence of excessive torque.

    Abstract: When abnormal torque occurs in a valve, water gate, etc., it changes speed of a load shaft in a reduction gears, which is transmitted from a worm to a rotary encoder via a main shaft connected to an electric motor and gears. An electric signal is fed from the rotary encoder to a microcomputer in which the abnormal torque is identified to stop the elctric motor. The microcomputer also identifies a full-opening point and a complete-closing point of the valve to stop the electric motor.

    Abstract: A universal load sensing gearbox integrating a safety mechanism for use, for instance, with motor driven closures, such as garage doors, barriers and gates, includes a housing which encases a worm slidably mounted on an input shaft and adapted for rotation therewith. The input shaft is connected with the motor driving the closure. The worm is engaged with a worm gear which is mounted on an output shaft which is connected with the closure. Dished washers are provided generally around the input shaft at both ends of the worm to urge the worm in a central meshed engagement with the worm gear. A motion transmission device is provided on the worm and is adapted to slide therewith to detect a longitudinal movement thereof and to transmit this movement to an actuating device which is adapted to stop and/or reverse the motor. Therefore, sufficient resistance to the rotation of the output shaft resulting, for example, from the closure encountering an object pressure, causes the worm to be displaced along the input shaft against the dished washers along with the transmission device. A sufficient movement of the transmission device causes the actuating device to trip a limit switch which triggers the stoppage and/or reversing of the motor. The load sensing gearbox is also intended for agricultural applications using reducing gearboxes, for actuating aircraft wing flaps, for conveyer belts, etc.

    Abstract: A speed reducer construction for use with a drive motor which has a drive motor housing and a drive motor shaft which extends out of the housing comprises a reducer housing which is adapted to be coupled to the drive motor housing and encloses a portion of the motor drive shaft. The motor drive shaft is advantageously journalled in the reducer housing and it carries a worm made of a Nylatron material which is rotatable therewith. An output shaft extends transversely to the drive shaft and is journalled in the reducer housing and it carries a sleeve which is keyed thereto for rotation therewith. A gear is freely rotatable on the sleeve alongside a collar portion of the sleeve and is in meshing engagement with the worm. The drive of the motor through the worm to the gear and the output shaft is regulatable by a clutching device including a clutch spring which is biased against an end of the gear with a biasing force which is regulated by a torque adjusting wheel which is threaded on the sleeve. The arrangement permits some slippage between the drive gear and the drive shaft during overload. The worm shaft is adjustable relative to the gear by means of an adjusting knob which may be fitted into an opening in the reducer housing so as to become engaged with the motor drive shaft.

    Abstract: To provide a torque limiting and overtravel stop device for aircraft actuation systems, where the overtravel stop is lightweight, bi-directional, repeatable and on-jamming, and allows for many revolutions of rotation between each end stop, the device includes a drive shaft having an input end and an end disposed in remote relation to the input end. A torque limiter is operatively associated with the drive shaft for rotational movement therewith and includes an input side adapted to receive input torque from the drive shaft and an output side adapted to transmit input torque from the drive shaft. The device includes a driven shaft having an input end driven by said drive shaft and an end disposed in remote relation to the input end with a traveling nut being disposed on the driven shaft for movement between the ends thereof. Gears are operatively related between said drive shaft and said driven shaft to normally provide a relative speed difference between the traveling nut and the driven shaft. The device further includes jaws for stopping movement of the traveling nut at the ends of the driven shaft so as to cause a torque build-up across the torque limiter by reason of the speed difference between the gears and the drive shaft sufficient to cause the torque limiter to prevent rotation of the drive shaft in one rotational direction.

    Abstract: A bi-directional advance gear having a torque limiting radial friction clutch is disclosed. The friction clutch comprises an annular member having an inner and outer periphery and having gear teeth defined by its outer periphery and radially inwardly projecting teeth on its inner periphery. A flat web substantially closes one face of the annular member to provide a shallow recess bounded by the projecting teeth and defines an opening concentric to the annular member. An inner member having a hub portion is rotatably mounted in the opening and has a pinion gear at one end. The other end of the hub has a plurality of radially extending rosette-shaped springs contained in the recess. Each spring has a pair of radially extending leg portions joined by an arcuate portion. Each arcuate portion has a lobe biased into engagement with the inwardly projecting teeth.

    Abstract: A gearing unit with planetary gearing stages employs a load sensor and a clutch for disengaging drive through the gearing should the sensor detect overloading. The load sensor is in the form of a stationary pin provided with a strain gauge transducer easily accessible via a bore in a housing. The pin bears on a rotatable component of one of the planetary gearing stages to hold this component stationary during operation and is subjected to force proportional to dynamic loading on the gearing. The clutch serves as a brake to hold a rotatable component of another planetary gearing stage stationary and on release permits this component to rotate to interrupt the drive.
