Abstract:
A drive mechanism for a vehicle is disclosed, said drive mechanism converting the reciprocating clockwise-counterclockwise motion of an input shaft into continuous rotation of an output shaft by means of two one-way clutches mechanically coupled to the input shaft and the output shaft, said one-way clutches having their power stroke in opposite directions of rotation. In an embodiment, said drive mechanism can be contained in a wheel hub and used for human-powered vehicles such as scooters, bicycles, wheelchairs, rollerskates, or other vehicles.
Abstract:
A multi-speed landing gear for a trailer includes a housing and a telescoping leg connected with the housing, and a gear assembly for extending and retracting the leg. The gear assembly includes a ring gear arranged to rotate about an axis transverse to the telescopic orientation of the leg member with the gear assembly configured to operate in a high speed setting and a low speed setting and automatically shift between the high and low speed settings, with an actuator selectively preventing or allowing rotation of the ring gear to enable the gear assembly to operate in the low speed setting or the high speed setting. The actuator may be connected to a shift member, with the actuator causing the shift member to selectively prevent or allow rotation of the ring gear by way of engagement of the shift member with the ring gear.
Abstract:
The valve is provided at its stopper (3) with a pin (4) combined to a spindle (5) which are coaxial and prevented to move in this direction but capable of rotating freely one with respect to the other so that, by means of the spindle (5), the nut (6) and the corresponding motor (9), the longitudinal movement of the stopper (3) is obtained in the valve opening and closing operations whereas, by applying directly a rotary motion by means of a second motor (23) to the pin (4) which does not affect the spindle (5), the stopper (3) rotates on the valve seat (2), to the closing position, causing a friction and consequent closer self-cleaning action.
Abstract:
The invention concerns a toothed gear as used in particular in drives to pivoting devices such as are used in articulated-arm awnings or windows. One shaft (5) rests, via a zone (10), against the other shaft (3), thus ensuring that the toothed gear proposed is extremely compact and stable to knocks and blows.
Abstract:
The electro-mechanical drive proposed comprises an electric motor (15), a transmission (17) and a restoring spring. In order to improve the ability of a drive of this kind to close the door, particularly in the event of a power failure, a large coil spring (25) is used as the restoring spring, the electric motor (15) being short-circuited when it is not powered in order to create a generator effect.
Abstract:
L'invention concerne un dispositif de commande de l'orientation des pales de soufflante d'un turbopropulseur comprenant au moins un ensemble (24a, 24b) de pales de soufflante à orientation réglable solidaire en rotation d'un anneau rotatif (28a, 28b) lié mécaniquement à un rotor (22a, 22b) de turbine. Chaque pale de l'ensemble est couplée à un support de pied de pale monté pivotant sur l'anneau rotatif au moyen d'un engrenage conique formé d'une première roue dentée solidaire du support de pied de pale et d'une seconde roue dentée (50) solidaire de l'anneau rotatif et portant un contrepoids (54) excentré par rapport à son axe de rotation. Un vérin (30a, 30b) solidaire en rotation du rotor de turbine et dont la tige (32a, 32b) est reliée à chaque contrepoids (54) par l'intermédiaire de bras de liaison permet de déplacer angulairement de façon synchronisée l'ensemble des contrepoids autour de l'axe de rotation de leur roue dentée respective.
Abstract:
A storage rack (30) with vertically arranged, horizontal drawers (38) movable by a crank mechanism is provided. Each individual drawer (38) of the storage rack (30) has a gear mechanism which is connected to a drive shaft (46) with wheels (44). A crank handle (54) is provided to engage the gear mechanism of any individual drawer and provide motive force to the drive shaft. The rotation of the crank causes the drive shaft to rotate and, in turn, rotates the wheels. The wheels travel along respective track members (50) attached the storage rack (30) to move a drawer in and out relative to the storage rack.
Abstract:
A window operator mechanism (10) includes a worm gear (22) which is generally parallel to the window when closed. A drive gear (24) is generally transverse and is at 45 DEG angle to the horizon. The operator (10) includes a housing (11) which is designed for drop-in assembly and includes three open gear receiving receptacles (15, 16, 17).
Abstract:
An angular adjusting mechanism for a headlamp assembly having a rigid two piece (30, 32) press fit molder gear housing assembly. The housing accepts a pair of angularly disposed bevel gears (116, 142) including a drive shaft (118) and drive gear (116) with the drive shaft (118) journaled in a bore (44) in one of the housing sidewalls (34) and the drive gear (116) positioned within the housing and bearing on the interior of the housing sidewall (34). A tubular nut (134) and an adjusting gear (130) engaging said drive gear (116) with the tubular nut (134) journaled in a second sidewall bore (54) and said nut (134) telescopically accepting an elongated adjusting screw (16) which is axially adjusted when the tubular nut (134) is rotated by the adjusting gear (130).
Abstract:
Arrangement for rotator units, especially those which are intended for rotation of excavator buckets. It comprises a motor (27) which, together with a transmission (26, 29) which is coupled to a drive wheel (24) in the chain transmission, is arranged in a bearing element (16), which is suspended in the housing (6) in a pivotable manner, but free from fixed connections to the housing. In the transmission there is a drive wheel (24) for a chain transmission, which wheel is connected by means of a drive chain (25) to a driven chain wheel (13) included in a shaft system (12) mounted in the housing. Spring elements (30) are arranged to pivot the bearing element (16) in such a way that the chain is held tensioned. The suspension of the bearing element in the housing is designed in such a way that deformations of the housing resulting from external force effect are not transmitted to the bearing element in a way that would deform the latter.
