摘要： The invention provides a simple, yet highly accurate device for synchronizing the speeds of two power-driven machines having separate, variable speed power-drives. A pair of shafts are respectively connected to the two machines and mounted in opposed concentric relationship for rotation in opposite directions at rates respectively proportional to the speed of rotation of the two machines. A differential unit is connected between the two shafts, such unit having equal size input and output sun gears respectively connected to the shafts. The planetary output of the differential unit is connected to a speed control element for at least one of the motors respectively driving the machines to vary the speed of such machine to bring it into rotational synchronization with the other machine. In accordance with a modification of the invention, if angular synchronization is also desired, a one-way clutch is provided between one of the shafts and its respective machine which is disengageable by a minimal torque produced by a difference in the rotational speed of the two shafts, and re-engages only in a fixed angular position when the two shafts are again brought into rotational synchronization.
摘要翻译：本发明提供了一种用于使具有单独的可变速度功率驱动器的两个动力驱动机器的速度同步的简单但高度准确的装置。一对轴分别连接到两个机器并以相对的同心关系安装，以相反方向旋转，速率分别与两台机器的转速成正比。差速单元连接在两个轴之间，这种单元具有相等尺寸的输入和输出太阳齿轮，分别连接到轴。差速单元的行星输出连接到用于至少一个马达的速度控制元件，分别驱动机器以改变这种机器的速度以使其与另一台机器进行旋转同步。根据本发明的变型，如果还需要角度同步，则在一个轴和其相应的机器之间提供单向离合器，该机器可以通过两个转速的差异产生的最小转矩分离轴，并且当两个轴再次进入旋转同步时，仅在固定的角度位置重新接合。

摘要： An improved planetary gear drive, employing multiple countershafts to reduce the loads carried by the individual components, is disclosed wherein at least one helical gear set having sets of oppositely inclined oblique teeth is mounted for axial movement on a common shaft to transmit power from a drive component to a power component. A compression spring, disposed contiguous with one face of the helical gear set, cooperates with the oppositely inclined teeth of the helical gear set to resiliently move the helical gear set axially along its shaft to equalize the axial force components on its oppositely skewed sets of teeth. The invention may be embodied at any one of several different points in the gear train.

摘要： A floating pinion engaged with a main gear, the floating pinion being mounted in a carriage adapted to roll along the periphery of the main gear. The carriage is interconnected with ground by two coupling bars symmetrically disposed on opposite sides of, and outside of, the main gear. Each coupling bar is connected to the carriage by an articulated joint at one end, and to ground through a universal type joint at the other end. Preferably, only a single universal type joint is used, that joint having an axis of rotation disposed in the median plane of the main gear.

摘要： A sprocket assembly having a two-piece hub supporting a sprocket wheel on a shaft. One part of the hub is circumferentially spaced from the other and both hub parts are interconnected by a pair of threaded studs each of which is pivotally supported at one end and carries a nut at the other end for adjusting the angular position of the sprocket wheel relative to the shaft.
