Abstract
A wave generator suitable for a small-sized or medium-sized harmonic reducer, including a main body that is a porous structure manufactured by powder metallurgy and includes a central shaft and an elliptically shaped plug encirclingly disposed on a circumference of the central shaft. An outer diameter of the elliptically shaped plug is in a range of 25 mm to 72 mm. The wave generator has a strength enabling the wave generator to bear a torque less than or equal to 18 Nm that overcomes the technical bias so as to provide a wave generator manufactured by powder metallurgy capable of fulfilling the required harmonic reducer, thereby reducing the manufacturing cost.
