摘要： The disclosure provides a torsional damper having a hub in which a boss adapted to be fixed to a rotating shaft, such as a crankshaft of an engine, and an annular rim are integrally provided via a plurality of stays, and an annular vibration ring connected to an outer circumferential surface of the rim via an elastic body. The stays have a circumferential width dimension that does not exceed one-quarter of the wavelength of the axial resonant frequency of the hub, and are thickened within a range in which the axial thickness dimension does not exceed one-half of the wavelength of the axial resonant frequency of the hub. Thickening of the stays is implemented by, for example, setting the axial thickness dimension thereof to a length equal to or more than one-quarter of the wavelength of the axial resonant frequency of the hub. The stays have an axially inclined shape.

摘要： A kind of gear is provided with shorter teeth, transition teeth and at least one longer tooth. The cross-section of the longer tooth is of a hawk beak shape, and the profile of the longer tooth is smoothly connected in series by a convex section, a tip section, a concave section, and a leading section. The two sides of the longer tooth are each provided with a transition tooth which neighbors a shorter tooth on the opposite side of the longer tooth. The pair of engaging gears according to this invention have advantages of reducing the fluid leakage, canceling the inertia of the rotors, and minimizing the vibration and noise. This invention also discloses a fluid machine for conveying, compressing or expanding liquid or gaseous fluids, which includes a casing comprising a housing, an upper end cover and a lower end cover. At least one pair of engaging gears which includes one driving rotor according to this invention and one driven rotor according to this invention is accommodated in the housing. As a result, the leakage between the rotors can be reduced, therefore the compression ratio can be improved. In addition, over compression and under compression can be avoided in operation.

from said clutch assembly (12) a primary shaft (23) comes out for controlling a gear reduction (19, 20) at the output of which reduction there is provided a coupling (21) to transmit the motion to a shaft (22) of the power take-off (15),
the machine also provides a hydrostatic assembly (25) which draws motion directly from said internal combustion engine (11) through said clutch assembly (12) and a first kinematic chain comprising a pair of bevel gears (28, 29),
said hydrostatic assembly in turn is connected to a second kinematic chain (34, 36) that retracts in the gearbox (14) and through its final transmission gear (40) controls an axle (41) of the wheels (13),
said machine providing three assemblies of shafts for the transmission of motion respectively: from the endothermic engine (11) towards the power take-off (15), from the endothermic engine (11) towards the hydrostatic pump (26) and from the hydrostatic motor (27) towards the final reduction (40), from the final reduction (40) towards the wheel axle (41) and the wheels themselves (13), wherein said assemblies of shafts are arranged on axes orthogonal to each other according to the main directions (X, Y, Z) of a three-dimensional Euclidean space.
