DOUBLE-CYCLOIDAL SPEED REDUCER

WIPO Patent Application WO/2024/045565

A1

A double-cycloidal speed reducer. The transmission of a double-cycloidal gear in an axial direction is driven by means of the transmission of an eccentric wheel of a first transmission portion, so that the double-cycloidal gear drives a second transmission portion to rotate synchronously. A first transmission assembly and a second transmission assembly are provided in an axial direction in which the eccentric wheel of the first transmission portion is located. A first pin wheel of the first transmission assembly is attached, by means of a first needle roller assembly, to a rolling path wall of an inner cavity where a first casing is located, so that when the double-cycloidal gear rotates to drive the first pin wheel to roll, the first needle roller assembly is synchronously driven to roll on the rolling path wall of the inner cavity where the first casing is located. During the transmission of the double-cycloidal speed reducer between the double-cycloidal gear and a pin wheel, the transmission mode of the pin wheel in a rolling path formed between the pin wheel and an inner cavity wall of the first casing/a second casing changes from sliding friction to rolling friction by means of a needle roller assembly, thus improving the efficiency of the whole speed reducer, and prolonging the service life of the speed reducer.
