How does the axle offset in a face-gear affect sliding speed and frictional losses? How has the formula of Xu been applied to different types of gears? What major changes can be expected in the speed values and slide-to-roll ratio based on the direction of coefficients of friction?
The gear ratio can also be used to determine the output torque of the system. Torque is defined as the tendency of an object to rotate about its axis; basically, the turning power of a shaft. A shaft with more torque can turn larger things. The gear ratio R is also equal to the rat...
One of the properties of involute gears is that the nominal gear ratio is constant, i.e. a constant angular velocity on the input shaft results in a constant angular velocity on the output shaft. The path of contact in this case becomes a straight line, which tangents the respective base...
Poisson’s ratio, strength, deformation modes and even damping coefficient (Supplementary Fig.21). One can also envision 3D metamaterials by using bevel gears, assembling planar gears into hierarchical configurations as in Fig.3or synthesizing different types of gear (Supplementary Fig.22). Integrated...
For certain applications such as robot arms, having a fixed gear reduction ratio would limit the choice of speed and torque outputs. Given the same actuator, robot arms designed to lift heavy loads (high reduction ratio) would only be able to move substantially slower than the ones that were...

Similar considerations with respect to spur gears can be made for the analyzed helical gearbox regarding the ratio of the power losses among the three different situations. However, it can be noted that helical gears exhibit lower power losses with respect to spur gears. This is related to the...
Where N(--) designates the number of teeth on the respective gear. R is the number of turns of shaft 36 for each turn of shaft 10, a number much less than one for high ratio stepdown gearing. A shorthand notation for the rotation ratio equation is ...
Now, if said first internal gear 18 is left to freely rotate and second internal gear 19 is fixed by bolt 20 to the inner cylindrical portion 10a of casing 10, the reduction ratio Ra in this case is evident in the manner of equation (c): ##EQU4## ...
