The shaft is operatively connected on its first end to the stationary gear (70), so that the shaft rotates about its axis as the yoke assembly (36) rotates relative to the stationary gear.
|Motor housing with integrated gears|
A motor housing with integrated gears includes a motor having a first shaft, the motor configured to actuate the first shaft, a dowel, the dowel rotatably coupled to the first shaft, an encoder configured to surround the dowel, the encoder being configured to measure an angular velocity of the first shaft, a gear system in meshed communication with the first shaft, and a second shaft in meshed communication with the gear system such that the motor is operable to transmit power to the second shaft. The housing further includes at least one seal, the seal located on the dowel between the first end and the second end of the dowel and creating a barrier such that the dowel is rotatable within the seal while preventing migration of lubricant on the at least one gear into the encoder..
|Propulsive apparatus for electric vehicles|
A propulsive apparatus for use in an electric vehicle includes a gear rotatable by a propulsive motor and having first teeth, and a constant velocity joint having an outer member which includes a larger-diameter portion having second teeth on an outer wall surface thereof. The second teeth serve as part of a speed reducer mechanism which is thus interposed between the propulsive motor and the constant velocity joint.
|Machine hydraulic system having fine control mode|
A hydraulic system for a machine is disclosed. The hydraulic system may have a hydraulic actuator, and at least one valve configured to regulate fluid flows associated with the hydraulic actuator.
|Ballistic combat glove|
Gloves for military and law enforcement personnel that provide ballistic protection from high velocity fragments, bullets, and projectiles, flame and heat.. .
