  • Patent number: 4765195
    Abstract: A stepless transmission of the non-friction type is provided using intermeshing non-circular gears. The transmission is made up of a number of angular velocity modulators each having first, second, and third shafts. Each shaft carries a non-circular gear thereon which meshes with the gear of a succeeding shaft. The angular velocity ratio .omega. of the third shaft of each modulator relative to the first shaft depends on the pitch curve of the intermeshing non-circular gears and on the position of the third shaft relative to the position of the first and second shafts. By changing the position of the third shaft the angular velocity ratio .omega. of the modulator can be steplessly varied. The output of the third shafts of each modulator are combined onto a common shaft by one the clutches to provide a continuous output. The position of the third shafts, and thus the overall ratio of the transmission, may be controlled automatically by a spring.

    Abstract: Two shafts rotatable about the same axis and having hubs are connected to each other by a transverse beam. One end of the beam is pivotally connected to one hub and the other end of the beam is pivotally connected to the other hub. Two roller followers are mounted to the beam with one follower located on each side of the beam's mid-point. The followers are guided by the interior surface of a closed path guide cam. In operation, the beam first pivots about the axis of one follower and then pivots about the axis of the other follower in a repetitive alternating sequence. For a given hub, the distance between the beam's pivot point and the hub connection changes each time the pivot point moves from one follower axis to the other. This causes one hub to alternately rotate at speeds which are relatively faster than, and then relatively slower than, the rotational speed of the other hub.

    Abstract: A hub (2) is rigidly torsionwise attached to a leading shaft (1) but free to move axially and radially. A rotary plate (3) is arranged on said hub (2) through a ball bearing (21) and carries a ring (4) provided with four conical transmission surfaces (30, 31). The transmission surfaces (30) of the ring (4) run on surfaces (33) of two rims (7, 8) of a wheel (6) integral with the casing, and the transmission surfaces (31) run on surfaces (34) of two rims (10, 11) of a second wheel (9) attached to the driven shaft (12) and coaxial with the wheel (6). The distance between the rims (7, 8 and 10, 11) is adjustable. When the driving shaft (1) rotates, the ring (4) effects a slow oscillation motion about the leading shaft (1) and transmits such motion to the wheel (9). The two transmission ranges are offset by 180.degree.. The eccentricity is adjustable between a maximum and zero, which allows the obtention of a reduction up to the infinite. A toothing may be provided in the transmission areas.

  • Patent number: 4475412
    Abstract: An infinite speed transmission having aligned input and output shafts with the input shaft driving a pair of eccentrics each of which oscillates an arm which in turn drives a gear plate housing in a rectilinear manner. Each gear plate housing slidably carries a gear plate equipped with multiple gear racks which drive a pinion gear mounted on the transmission output shaft. Gear plate and pinion engagement for unidirectional rotation of the pinion gear is controlled by a cam which shifts the gear plates within their respective housing. Speed changes are effected by relocating the eccentric driven arms relative the gear plate housings driven by the arms. Repositioning of the cam results in the output shaft mounted pinion being driven in a reverse direction.

  • Patent number: 4440004
    Abstract: A vertical axis flow through type clothes washing machine with a basket driving transmission which imparts a wobble action to the basket during wash and conventional rotational motion during spin operations. The transmission supports the basket such that when the input drive shaft rotates in its wash direction, the central basket axis is canted relative to the substantially vertical axis of rotation of the drive shaft. As the shaft rotates, the central basket axis describes an inverted cone thereby imparting the wobble action to the basket which is prevented from rotating about its own axis. When the drive shaft rotates in the opposite direction for spin, the central axis of the basket is substantially coaligned with the vertical axis of rotation of the input drive shaft, and the basket is rotated about its own axis for centrifugal extraction of liquid from the clothes in the basket.

  • Patent number: 4438656
    Abstract: An improved power transfer device utilizes an input power source supplemented by an unbalanced weight assembly which increases the torque on an output shaft as a function of load associated with the device. The input shaft is provided with a drive gear in operable engagement with an internal toothed ring gear, and the ring gear is provided with a plurality of diametrically opposed, radial extensions to which weight support arms are pivotably attached. The remaining free ends of the weight support arms are attached to the outer extensions of a cruciform support and are further in parallel alignment with and fixedly secured to elongated weights, such securement being offset from a central portion of the weights. A difference in load between the input shaft and output shaft results in the ring gear shifting in an unbalanced manner relative to the output shaft so as to deliver an additional torque to the shaft through the shifting of the unbalanced weights.

  • Patent number: 4411165
    Abstract: A rotor of the transmission is journaled within a stationary housing and is driven by rotatable gear rack components therein. A pinion gear drives the gear rack components by sequentially meshing with spaced apart gear racks on each component. A speed selector assembly positions the pinion gear relative the rotor axis and includes a gear train to couple the gear to a power input shaft. Speed changes between the input shaft and a rotor driven output shaft are effected by positioning of the pinion gear away from the rotor axis resulting in the gear rack components moving eccentrically within the rotor. A cam structure acts on each gear rack component to control meshing of the gear racks on the component with the pinion gear. Each of the pairs of gear racks on a modified form of the transmission are resiliently mounted on their respective gear rack assemblies. Rails of each gear rack assembly rotate about stationary but adjustable cam rings of the transmission.

  • Patent number: 4299133
    Abstract: A gearing has on its driving shaft a drive means carrier member carrying drive means in the form of pins protruding towards a driven means carrier member fixed to the driven shaft and carrying divergently arranged driven means. The driven shaft is offset relative to the driving shaft so that the circular orbital path of movement of the driven means surrounds the circular orbital path of movement of the driven means. From the drive means always only one single drive means contacts a driven means and only in a portion of the orbital path thereof which portion is more remote from the axis of the driven shaft than that portion of this orbital path arranged nearer to the driven shaft. In the other portions of their orbital path, the drive means pass within the orbital path of the driven means but do not contact these. This results in an increased torque of the driven shaft.
