摘要：一种利用差动轮系进行无级变速和改变转向的装置，在输入轴保持高速运转的同时，输出轴可以方便地实现正转—零—反转的无级变速要求。本发明通过2K—H型差动轮系的输入轴(9)带动一机械式无级变速器控制另一中心轮(5)的转速。两个中心轮(2)、(5)相对独立地转动，当转向相反时，若它们的线速度相等，则行星轮没有公转，系杆H或输出轴不动，若它们的线速度不等，系杆随线速度较快的一个中心轮的方向转动。

摘要：该发明属于机械传动领域，用于输出转速需频繁变换，而又并非严格均匀的场合。该装置的输入轴上装有一个齿轮，通过一个行星轮及系杆与另一端为输出轴上的中心轮连接。可控制变速机构是在由输入轴齿轮与系杆间组成的传动键上加入了一个由可控制的离合装置，使系杆做连续的或间歇式的转动，或做被动式的随动空转。其转动的快慢则是靠系杆在做间歇式转动时，所受周期转动的时间长短来确定的。

摘要： A bicycle coaster brake hub having a gear-transmission therein is provided with a change-over mechanism between a driving member or clutch always rotatable together therewith and a gear frame including planetary gears and carrying actuators, such as rollers or a clutch, for operating brake shoes of a braking mechanism. The change-over mechanism causes a reverse rotation of the driving member induced by back-pedalling to be transmitted to a ring gear instead of the gear frame, whereby the gear frame is always reversely rotated through the ring gear at any driving speed stage from low to high thus braking the bicycle wheels with a uniform braking effect regardless of what speed stage the gear-transmission is in at the time of braking.

摘要： In the hub shell of a bicycle or the like a gear shifting mechanism mounted to be axially moveable is such that when the pedal is reversely rotated it is transferred in the axial direction and expands the brake shoes to forcibly press the same against the inner walls of the hub shell, thereby braking the rotation of the bicycle wheel. Thus by transferring the gear shifting mechanism for the braking purpose, it is possible at any time when necessary to secure the most reliable braking effect, in whatever speed changing condition the gear shifting mechanism may be or even if any parts thereof are damaged and even if the wire rope thereof has been extended in protracted use.

摘要： A down shift mechanism for incorporation in a device such as an assembly tool includes a wrap spring which locks and releases a planetary gear speed reduction assembly to provide shifts between two drive ratios in response to torque throughput. The wrap spring is received upon a drive drum within a cylindrical housing. The ends of the wrap spring are engaged by a pair of relatively rotationally adjustable and fixable spring engaging lugs which adjust the preload of the wrap spring and thus the torque level at which the spring unwraps and lifts off the drive drum and thus the torque level at which the shift occurs. The wrap spring housing is coupled to the ring gear of the planetary gear assembly. When the torque applied to the wrap spring exceeds the preload, the spring unwraps, unlocking the ring gear and planetary gear assembly and downshifting to the speed reduction determined by the planetary gear assembly. An alternate embodiment of the downshift mechanism is also presented.

摘要： A bi-directional, speed reducing mechanism for use with hand-held power tools comprises a pair of epicyclic gear trains mounted in a common carrier which each independently engage one of a pair of cages or ring gears disposed thereabout. The cages may alternately be locked in a stationary position or released for free rotation by independent activation of one of two identical wrap spring brakes disposed about each of the cages. The mechanism is contained within a generally cylindrical housing suitable for positioning between a conventional unidirectional power tool motor and gear head or powered device. In addition to the reversing capability, speed reduction in the range from 3.5:1 to 9:1 is also achieved by this mechanism.

摘要： A reversible speed reducing mechanism for use with hand-held power tools comprises a pair of juxtaposed epicyclic gear trains mounted in a common carrier which independently engage a pair of cages or ring gears. The cages may alternately be locked to or released from an outer housing to accomplish the bidirectional transmission of rotational power. The complete reversing mechanism is housed in a generally cylindrical body suitable for mounting between a conventional unidirectional motor and gear head or powered device. Forward or reverse output rotation is selected by moving a control button positioned on the periphery of the reversing mechanism. Speed reduction in the range from 3 to 5 to 1 can be achieved by this mechanism.
