Wang Hongxin. Kinematics and Force Analysis of Screw Pair Steel Ball Planetary Transmission Mechanism[J]. 1998, (1). DOI: 10.16578/j.issn.1004.2539.1998.01.003.
This paper introduces the construction composition and transmission principle of the screw pair steel ball planetary transmission mechanism with a coaxal input and output axes
calculates their transmission ratio function
gives the geometrical conditions of loading steel balls even distributed in space
presents the construction parameter constraint equation of the internal and external screw surfaces under the conditions of the steel ball loaded through three points
and sets up the calculation method of counteraction forces on bearings under space forces action.
