摘要： Device and method for providing rotational power using power transmission are disclosed. The device enables multi-dimensional and angle-agnostic displacement of the rotational power output with respect to the input location and transference of high-torque and high-speed rotational movement, while preserving maximal efficiency and quick response. The device is a transmission gear that comprises at least two gear-links in a multi-link articulated gear (MLAG). Each of the links comprising at least two gear wheels. The transmission gear further comprising a common axis adapted to allow the links to rotate freely with respect to each other about the common axis and thus to allow change of the angle between the at least two links and thereby to change the distance between the input shaft and the output shaft.

摘要： A pedaling vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. A user can fully exercise muscles of the user's body during exercise, and a vibrational effect generated by the eccentric assembly can stimulate acupuncture points of the user's body to improve blood circulation. Left and right pedals of the pedal assembly can be treaded in turn to continuously drive a gear to rotate in a same direction so as to achieve an effect of acceleration and to enhance vibrations.

摘要： A mechanical device lubrication level control system operates within a mechanical housing having a sump cavity and a lubricant director, where the lubricant director is located at the bottom of the housing. A mechanical gear set is located in the sump cavity and a lube tank is located in the lubricant director. There is located within in lube tank either a motor with a pump or an expandable air bladder that is inflatable by an air source. For the lube tank having the motor with the pump, the pump controls the lubricant within the sump cavity. For the lube tank having the expandable air bladder, the air source controls the lubricant within the sump cavity.

摘要： A drive device includes a shaft rotatably supported by a first bearing and a second bearing. The first bearing is disposed in a shaft hole of an output frame end. The second bearing is disposed in a bearing box of an opposite-to-output frame end. An oil seal is fixed in the shaft hole and is closer to an output end than the first bearing is, and is in sliding contact with an outer circumference of the shaft. A biasing member is housed in the bearing box and biases an outer race of the second bearing toward the output end. Accordingly, a deflection amount and a bend amount of the shaft at the location where the oil seal is disposed may be reduced.
