Title:
FLEXIBLE WHEEL FOR HARMONIC SPEED REDUCER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/000995
Kind Code:
A1
Abstract:
A flexible wheel for a harmonic speed reducer and a manufacturing method thereof, the flexible wheel for a harmonic speed reducer comprises a metal gear ring (1) and a plastic cup bottom (2); wherein, a nano combination part (11) is arranged on the metal gear ring (1), the inner and outer surfaces of the nano combination part (11) are subjected to a nano treatment; the plastic cup bottom (2) is formed by injection molding in a mold; and the nano combination part (11) of the metal gear ring (1) is embedded into the plastic cup bottom (2). The flexible wheel for the harmonic speed reducer comprises two parts, the metal gear ring with a relatively higher size precision requirement and the plastic cup bottom with a relatively lower size precision requirement; in this way, on one hand, the size precision and service life of the flexible wheel for the harmonic speed reducer can be ensured, and on the other hand, the manufacturing process can be simplified, the single processing time can be shortened, the production efficiency can be improved, the production cost can be reduced, and the benefit maximization can be realized.
