Offer on said countershaft-gear, jack shaft and the midship shaft bearing and interconnect second oil groove that is used for lubricated midship shaft bearing.
Offer on said midship shaft bearing outer ring, housing and the bearing of input shaft outer ring and interconnect the 3rd oil groove that is used for lubricated bearing of input shaft.
Said first oil groove comprises output shaft gear section, output shaft axial direction part and output shaft radial section; The output shaft gear section is connected with the output shaft axial direction part after being through to the output shaft gear center from the output shaft gear bottom; The output shaft axial direction part runs through whole output shaft center line, and the output shaft radial section connects output shaft axial direction part and output shaft bearing.
Said second oil groove comprises countershaft-gear section, jack shaft axial direction part and jack shaft radial section; The countershaft-gear section is connected with jack shaft axial direction part inboard after being through to the jack shaft center from the countershaft-gear bottom; The jack shaft axial direction part outside extends to the jack shaft end, and the jack shaft radial section connects jack shaft axial direction part and midship shaft bearing.
Said the 3rd oil groove top is opened in the outer ring of midship shaft bearing, and intermediate section is opened on the housing, and end is opened in the outer ring of bearing of input shaft.
The countershaft-gear section top of the output shaft gear section top of said first oil groove and second oil groove is respectively arranged with oil skipper.
The invention has the beneficial effects as follows: under low output speed, this oil duct can guarantee the round-the-clock lubricated of bearing and gear, has satisfied the needs of low jig frequency pumping unit.
