The Analysis of Down-hole Reducer in Transmission Scheme
Jin Lian-deng · Oil Field Equipment · 2007
This paper presents structure features of down-hole reducer,and analyzes the available transmission schemes which contain fixed-axis gear-train transmission,2K-H type planetary gear-train transmission,3K type planetary gear-train transmission and planetary gearing with small tooth transmission according to the structure features of the down-hole reducer.One scheme conforming to the petroleum well drilling operating mode request transmission plan was chosen at last.
