Abstract:
A washing machine is provided. The washing machine adopts an induction motor to achieve efficient operation as that achieved by using a frequency converter. The washing machine includes: an input shaft configured to supply rotation power to a rotation part that rotates washings; an induction motor, configured to rotate in a forward direction and a backward direction and served as a power source of the rotation part; a transmission-arranged between an output shaft of the induction motor and the input shaft of the rotation part. The transmission is configured to change speed of the induction motor by decreasing a reduction ratio along with startup of the induction motor.
Abstract:
A variable-speed belt drive pulley assembly includes a plurality of pulley segments, a plurality of sliders, and a rotatable hub. Each segment is adapted to engage a drive belt and is mounted to an outer end of a corresponding slider which is slidably received by the hub. Each slider may be a pair of rods extending from the body in parallel relationship to each other. The hub has a plurality of bores. Each bore slidably receives a corresponding one of the rods. An actuator device moves the segments radially inwardly and outwardly with respect to the hub. A coil spring is mounted on each the rods, and is biased to urge one of the segments radially outwardly.
Abstract:
A versatile, variable gear ratio mechanical transmission system is providing having similar first and second spaced Disc Subsystems connected by a belt or chain. Each subsystem of which comprises three primary components: (1) a Shift Actuation Structure located at one outermost side; (2) a Receiving Disc located at the opposite side; and, (3) a Retention Disc sandwiched between. The Retention and Receiving Discs accommodate concentric rings of proportionally spaced holes in which corresponding smooth, contoured or toothed Headed Pins are maintained, engaged, or retracted. When the pins are engaged, they span the slot between the Receiving Disc and Retention Disc and interface with the conveyance transferring load from Driving Disc Subassembly to the Driven Disc Subassembly.
Abstract:
Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.
Abstract:
A cone to which one or several torque transmitting member(s) are attached as to form at least one torque transmitting arc on the surface of the cone. The torque transmitting member(s) will be used for torque transmission between at least one rotational energy conveying device and the cone. The torque transmitting member(s) are attached in a manner such that significant circumferential sliding that occurs between the torque transmitting surface(s) of the torque transmitting member(s) and the torque transmitting surface(s) of the rotational energy conveying device(s) when the pitch diameter of the torque transmitting member(s) is changed can be eliminated, such that wear and frictional energy losses are significantly reduced, and positive engagement devices, such as teeth, can be used for torque transmission between the torque transmitting member(s) and the rotational energy conveying device(s). The cone with torque transmitting member(s) can be used to construct various Continuous Variable Transmissions that have a long life, low frictional energy losses, and can be made non-friction dependent.
Abstract:
A variable ratio chain-belt transmission for use in a vehicle, includes a pair of variable ratio pulleys having a plurality of pins which are lined in a plurality of circles, a chain-belt engaging with both variable ratio pulleys. Different sized pulleys are formed by pushing and pulling the pins in and out of engagement with the chain-belt by activating various solenoids, whereby various pulley ratios are formed when the plurality of pins form different relative sized pulleys. A clutch mechanism for use with the variable ratio chain-belt transmission includes distinct forward and reverse clutch assemblies.
Abstract:
A self adjusting tensioning system for a variable transmission. An endless belt is advanced by and supported on a pair of spaced apart, variable diameter, sheaves which are independently movable between reduced and enlarged configurations and which result in the belt assuming different paths. A pair of rollers are rotatably mounted at fixedly spaced locations on an enlongated carrier member. One of the rollers is actively biased into engagement with the belt by a compression spring assembly. A cam surface on the carrier member proximate the other of the rollers is slidable along a fixed contoured supporting surface and passively assures engagement of the other of the rollers with the belt. As the ratio of the transmission changes with changed diameters of the sheaves and the belt thereby assumes a changed path, the belt is effective to automatically move the rollers therealong so as to maintain a substantially constant tension in the belt.
Abstract:
A wheel (1) with variable diameter comprises two mutually opposed disks (2, 3) that can be displaced with respect to each other in the direction of their axis of rotation (6), wherein plates (9) are guided in a substantially radially displaceable fashion. The plates (9) taper in the peripheral direction as measured from one disk (2 or 3) toward the other disk (3 or 2) and are coupled displaceably with each other along their lateral surfaces (20). At least one sliding member (15) is arranged on each plate (9) and is displaceable along a sliding path (19), on the one hand, in the direction of the axis of rotation (6) of the wheel (1) and, on the other hand, in the peripheral direction against the force of springs (18), this sliding member (15) carrying at least one entrainment member (16) for engagement into a load transmission member (22).
Abstract:
A torque transmission apparatus having an infinitely variable gear ratio particularly suited for use as a bicycle transmission. The apparatus may be mounted on conventional bicycles and replaces the usual derailleur mechanism. A novel means is used to effect the gear changes which requires less force than previous devices. All force transmitting components of the apparatus are mechanically engaged without relying on friction which eliminates any possibility of slippage within the transmission.
Abstract:
The invention relates to a drive device having stepless torque adjustment, especially for cycles. The drive device comprises a drive shaft (13), a first adjusting disc (1) arranged coaxially with the drive shaft (13), into which first adjusting disc (1) a spiral-like cutout (3) is incorporated at least partially about the center of the first adjusting disc (1), a second coaxially arranged adjusting disc (5) into which through slots (6) are incorporated which run outwards from the center of the second adjusting disc (5), and a coaxial segmented ring (27) consisting of individual segments (28) onto the outer periphery of which segmented ring (27) can be placed an endless drive element (30). The segments (28) each have extensions (43) which engage both in the spiral-like cutout (3) and in an allocated through slot (6). One of the said adjusting discs can be driven by the drive shaft (13), whereas the other non-driven adjusting disc can be blocked by means of a blocking device (10a and 10b). When one adjusting disc is blocked and the other rotates, the diameter of the segmented ring (27) can be continuously changed, so that the torque is infinitely adjustable to the desired value.
