Constant velocity joint Chronometry Isochronism 1. Introduction 1.1. Oscillator time-bases without escapement The biggest improvement in timekeeper accuracy was due to the introduction of the oscillator as a time base, first the pendulum by Christiaan Huygens in 1656 [18], then the balance wheel-...
an outer cup composed of soft elastic material at least partially containing the inner cup and having elongated ribs disposed on the outer surface of the outer cup to support the outer cup in the ball joint socket, spaced apart from the ball joint socket whereby the plastic ball socket may ...
joint change with its activities, whereas the rotation axis of the subtalar joint is relatively stable [21]. Therefore, this study adopts the UR model as the kinematic equivalent model of the human ankle, in which the tibiotalar joint is equivalent to the U-pair and the subtalar joint is ...
Spherical plain bearings are composed of an inner ring or raceway that fits into an outer housing or shell to create an articulated joint. The spherical inner ring is able to move freely within the outer raceway, allowing rotational and angular movement in multiple axes and planes. This flexibil...
A new spherical joint mechanism which is well suited to parallel robotics is presented. The concentric multilink spherical (CMS) joint allows two or more s... GJ Hamlin,AC Sanderson - IEEE 被引量: 99发表: 1994年 Analysis of Failure Mechanism of Super Large Diameter Welded Hollow Spherical J...
All legs start to deploy from the outer shell using only the third joint of each leg and the shell starts to rotate as shown in B. After the outer shell rises and its center pole becomes vertical, the rising motion is finished by standing up with a paddle motion by the legs as shown...
