A wobble gear system is provided with an arrangement of gear elements that permits a motive input to drive planet gear elements to increase the gear reduction ratio while maximizing efficiency of the wobble gear system. The wobble gear system may have eccentrically rotating or oscillating wobble elements including a wobble plate and compound planet gear elements that are non-collinear and may be driven by the motive input, increasing the realized gear ratio in a single stage without reducing efficiency. One wobble gear system embodiment may employ a plurality of ring-supported and driven compound planet gear elements with laterally offset non-collinear central axes to optimize eccentricity and enhance gear reduction ratios. The wobble gear system may be integrated with components of a vehicle drive wheel driven by an in-wheel motor to produce speeds and torques required to drive vehicles including automobiles and aircraft.

A vibratory system for a screening and/or feeder machine, the vibratory system including shaft lines, each shaft line having an unbalance module, the vibratory system also having a drive device configured to drive the shaft lines in rotation in synchronous manner and in the same direction. The vibratory system also includes an angle modifier device configured to modify the angular position of the unbalance module of one shaft line relative to the angular position of the unbalance module of the other shaft line or of one of the other shaft lines.

An arrangement including a bushing having a bushing hub, a bushing flange, a housing containing a uni-directional bearing, an axle extending outward from the uni-directional bearing, and a stationary torque arm attached to the axle of the bushing. The bushing hub is inserted into a recessed hub section of a sprocket, and securely connected to the sprocket. The arrangement may also include a driven device attached to the bushing hub, and an endless drive belt and motor.

An actuator (1) having two detent devices (2) which include in each case at least one terminal detent element (3) for a part (27) of a drive train, and at least one adjustment element (4, 19) which is operatively connected to the terminal detent element (3) and is specified for setting a position of the terminal detent element (3). The at least one gear unit (5, 18) is disposed between the at least one terminal detent element (3) and the at least one adjustment element (4, 19).

A gearhead for a handheld power tool for machining workpieces, having a housing in which an output that can be connected to a drive of a handheld power tool is accommodated, and also having a tool shaft to which a tool can be coupled, wherein a braking device that can be moved between a braking position and a release position and that acts upon the tool shaft is provided for braking of the tool shaft. A switching device is provided that can be moved between a first switching position, in which the tool shaft is connected to the output in a power transmitting manner and in which the braking device is transferred into the release position, and a second switching position, in which the tool shaft is decoupled from the output and in which the braking device is transferred into the braking position.

A valve opening and closing timing control apparatus includes: a driving side rotator disposed rotatably about a rotation axis and configured to rotate synchronously with a crankshaft of an internal combustion engine; a driven side rotator disposed rotatably about the rotation axis and configured to be rotatable relative to the driving side rotator and to rotate integrally with a valve opening and closing camshaft of the internal combustion engine; and a phase adjustment mechanism configured to set a relative rotation phase between the driving side rotator and the driven side rotator by a driving force of an electric actuator. The phase adjustment mechanism includes: an internally toothed ring gear; an inner gear; and a drive shaft, and the valve opening and closing timing control apparatus further includes: a biasing member; and a displacement regulation portion.

A surgical device adapter for coupling an end effector to a surgical device includes: a proximal joint housing that is couplable to the surgical device; a middle joint housing pivotally coupled to the distal end of the proximal joint housing; and a distal joint housing pivotally coupled to the distal end of the middle joint housing. The middle joint housing is pivotable about a first pivot axis defined between the proximal joint housing and the middle joint housing. The distal joint housing is couplable to the end effector and pivotable about a second pivot axis defined between the middle joint housing and the distal joint housing, the second pivot axis being transverse to the first pivot axis.

A rotary device includes a rotatable member, at least one movable ring, and a supporting member. The supporting member includes a stopping portion. The rotatable member includes a rotary ring and a positioning portion. The movable ring includes an acting portion. The rotary ring and the at least one movable ring are coaxially disposed on the supporting member, and the movable ring is disposed between the rotatable member and the supporting member. The rotary ring and the at least one movable ring is capable of rotating relative to the supporting member. A part of the positioning portion overlaps the movable ring. When the rotary ring rotates relative to the supporting member, the part of the positioning portion pushes the acting portion, to drive the at least one movable ring to rotate until the acting portion is stopped between the positioning portion and the stopping portion.
