Abstract: At present, the design of parallel kinematic mechanism (PKM) generally starts from type synthesis based on the motion pattern and then the dimensions are synthesized based on performance requirements. The synthesized type ...

Abstract: Face gear drive has been widely investigated in the aviation field as a power split device on the helicopter main reducer. However, high-speed and heavy-load condition makes the face gear prone to tooth surface pitting, ...

Abstract: Noncircular bevel gear is applied to intersecting axes, realizing given function of transmission ratio. Currently, researches are focused mainly on gear with involute tooth profile and straight tooth lengthwise, while that ...

Abstract: As a prospective machining method for cylindrical gear, gear skiving has been promoted by many commercial companies, such as Gleason, Mitsubishi, and Prawema recently. Although the principle and mathematical model for gear ...

Abstract: Noncircular bevel gears are applied in variable-speed transmissions with intersecting axes. Since dedicated machines for manufacturing noncircular bevel gears are not available, noncircular bevel gears are normally ...

Abstract: Gear shaping, commonly regarded as the most widely used machining method for cylindrical gear, is in fact an ideal manufacturing method for noncircular gear due to its merit of not being restricted by gear type or pitch ...

Abstract: Gear shaping, a widely used machining method for circular gears, was generalized to noncircular gears in recent works using a 3-linkage machine tool. As the pitch curve normals of noncircular gears change constantly in ...
