  • Device for measuring moving range of side gear
    Patent number: 9920825
    Abstract: A moving range measurement device of a side gear used in a differential unit, the differential unit including: a differential case; a side gear arranged inside the differential case; and a spring that biases the side gear in a direction parallel to a central axis, in which: the device includes: a jig in which a slope is formed, the jig being slidable in a direction vertical to the central axis of the side gear; and an actuator that slides the jig, and the actuator slides the jig to make the jig move toward the side gear in a state in which the slope is in contact with the side gear, to thereby move the side gear along the slope.

  • Dummy shaft, apparatus for assembling differential unit using dummy shaft, and method for manufacturing differential unit
    Patent number: 9657830
    Abstract: Disclosed is a dummy shaft which prevents washers from falling off. In addition, disclosed are an apparatus for assembling a differential unit using the dummy shaft, and a method for manufacturing the differential unit. Specifically disclosed is a dummy shaft for temporarily assembling a differential unit by being inserted into a pinion gear, and a washer in contact with an outer surface of the pinion gear, including a body portion, and a movable portion slidable in a direction toward or away from the body portion. The movable portion has a receiving groove for catching the washer.
